Abstract (sommario):

Management of animal waste, originating from agriculture and food production, has to be disposed in a safe, financially justified manner and practical solutions which are in accordance to EU regulations, have to be applied. According to the Regulation (EC) No 1774/2002 animal waste is categorized in three categories. Categorization of the waste is a precondition for proper and harmless treatment of waste from the aspect of public health and protection of the environment. The first category consists of dangerous matters that are disposed in an incinerator at 1200oC. The second and third category may be used in processing or in production of biogas and compost, but according to the prescribed procedures. This paper presents a practical solution in processing of animal waste of all three categories: building a composting facility and an incinerator. The composting facility consists of covered concrete plateau, boxes for composting, area for keeping the compost, roads for mechanization, premises for maintaining hygiene of workers, space for incinerator and a fence with a gate. This facility should be built according to the previously designed construction project. Safe management of animal waste is, according to this suggestion, possible because biodegradation is carried out by the help of commercial heterotrophic microorganisms and plants distributed in layers. Compost, originating from the litter on farms, is mixed with the compost that originates from animal waste. The obtained compost has to be analyzed on pathogen microorganisms and pedology composition and than used in crop production. It was concluded that this way of animal waste is safe, financially justified and according to the European regulations.

Abstract (sommario):

Confined food-animal operations in the United States produce more than 40 times the amount of waste than human biosolids generated from US wastewater treatment plants. Unlike biosolids, which must meet regulatory standards for pathogen levels, vector attraction reduction and metal content, no treatment is required of waste from animal agriculture. This omission is of concern based on dramatic changes in livestock production over the past 50 years, which have resulted in large increases in animal waste and a high degree of geographic concentration of waste associated with the regional growth of industrial food-animal production. Regulatory measures have not kept pace with these changes. The purpose of this paper is to: 1) review trends that affect food-animal waste production in the United States, 2) assess risks associated with food-animal wastes, 3) contrast food-animal waste management practices to management practices for biosolids and 4) make recommendations based on existing and potential policy options to improve management of food-animal waste.

Abstract (sommario):

The study was conducted in rural areas of Mymensingh district during March to April 2007. Seventy two households were interviewed and respondents were grouped in three categories: low, medium and high income group to identify the respondents socio-economic condition, total waste production, processing, utilization and preservation methods of waste. The total organic waste production was unequally proportionate areas among low, medium and high income group. Waste generation was also depending on family size and family income. Smaller family generated less amount of waste while larger family generated huge wastes. High income contributes to generate more wastes. The characteristics such as family size and family income of the respondents had positive and significant relationships with their waste generation. Waste use as many purpose such as manure, fuel, landfill etc. A significant amount of waste generated from domestic animal, specially cowdung have been using as fuel purpose. Only 2.78% respondents used cowdung as compost in their crop field due to less number of domestic animals and scarcity of fuel wood. But 27.78% respondents were not used it for any of those purposes. Besides these ashes, kitchen waste, feed wastage etc. are used as manure and landfill purpose. Respondents had no systematic planning in all spheres of production, processing and utilization of organic waste. The respondents were disposing their solid waste at various times. As a result improper processing and preservation of wastes have been occurring serious air and water pollution.DOI: http://dx.doi.org/10.3329/pa.v18i2.18383 Progress. Agric. 18(2): 247 - 254, 2007

Abstract (sommario):

Healthcare wastes are generated by human or animal healthcare facilities. A small portion of these wastes are considered dangerous. However, accidents generated by incorrect waste management is a reality around the world. Accidents happen in different management stages, from the waste generation to its final destination, if waste is not properly managed. Therefore, this work aimed to discuss the possible problems related to the incorrect healthcare waste management, focusing on public health. This mini-review discussed some of the ways in which waste management can favor the preservation of public health and the environment, through steps such as minimization, segregation and recycling.

Abstract (sommario):

In the work presents the results of the analysis of the current state of polymer waste management in Ukraine and the world. It is known that the vast majority of such waste accumulates in landfills or enters the natural environment. Such a threatening situation requires the search for an effective solution to the problem of polymer waste management, since its processing contributes to the preservation of natural resources and the solution to the problem of the shortage of polymer raw materials. The quantitative and qualitative composition of such waste was analyzed and it was established that the most frequently used types of plastic are polyolefins. Since the management of a large amount of plastic waste is a difficult task, the state regulation of the polymer waste management system is of great importance in this area. In Ukraine, this is being implemented thanks to the adoption of the National Waste Management Strategy in 2017. An assessment of possible ways of recycling polymer waste was carried out in order to solve the problem of shortage of polymer raw materials. Today, polymer waste can be disposed of in three directions: material (polymer-raw material); raw materials and energy. The main methods of their processing and directions of use of the obtained products were studied. The most popular methods are physical, chemical and thermal. It has been established that the recyclates obtained in this way can most often be used in the food, processing, construction industries, as well as in automobile and aircraft construction. A fairly promising direction of using recycled products is light industry products with additional hydrophobic, fire-resistant, flame-retardant, conductive, heat-insulating, anti-corrosion, airtight and other operational properties.

Abstract (sommario):

The paper analyses the peculiarities of waste management in Zhytomyr region over the last 5 years. There was a significant decrease (up to 40 %) in the amount of wastes belonging to the hazard Classes I–IV as well as almost 40 times reduction in waste products of the hazard Class III. The largest amount of waste products of the hazard Classes I–IV was formed in Popilnia district, Andrushivka district and Zhytomyr. The smallest amount of these waste products was found in Pulyny, Brusyliv and Baranivka districts. The highest amount of available waste products was registered in Zhytomyr, in Korosten and Ovruch districts respectively. Berdychiv, Malyn and Brusyliv districts were characterized as those ones generating the least amount of waste products. The waste products of mining industry and wastes of organic nature, videlicet wood waste, plant and animal waste account for 28 % of all the wastes generated for the period of 2016. Household wastes, other mineral wastes, and dead rock account for 22 %, 21 % and 16 % respectively. The lack of properly functioning infrastructure (first of all, the system of separate collection) causes annual losses of million tons of valuable resources contained in waste products. The simultaneous need of domestic processing enterprises for such raw materials is solved nowadays by means of purchasing such recyclable materials from other countries. The issue of further implementation of low-waste technologies as well as the improvement of regulatory and legal support in the field of waste management need urgent solving.

Abstract (sommario):

With the development of agriculture in India, the production of agricultural wastes increased rapidly. Basically these wastes are bio products and are very important for survival of animals and human beings. The occurrence of agricultural wastes is unique in the different areas. The agricultural straw and livestock excrement are considered to be potential resources. These substances are widely available on earth and can be a good source of energy or be converted into useful products. The wastes generated from crop have a good potential to convert to energy through related energy sector. The waste produce from animal or from crop residue is called biomass which has an interdependent relationship with ecosystem from production to disposal and has physicochemical properties. The recycling and utilization of agricultural wastes are considered to be the important step in environmental protection, energy structure and agricultural development. The present review deals with the research work carried out in the conversion of biomass and agricultural waste and to illuminate the potential environmental risk, recycling and utilization pathway, influencing factors and policy suggestions in the recycling and utilization progress of agricultural wastes. An attempt is carried out to increase the economic value of agricultural waste into useful product. The survey provided the development mode of industrialization and scale of agricultural waste recycling. The recycling and utilization pathway of agricultural wastes were also analysed. The crucial suggestions may be proposed, such as cultivating new industry, building economy incentive standard, improving laws and regulations, and creating rural market strengthening medium and long-term plans of agricultural waste recycling. The resource consumption, ecological crisis and other issues caused by agricultural wastes were evaluated.

Abstract (sommario):

Solid waste management is a crucial issue in developing countries due to large amounts of waste being generated from different sources. Aerobic windrow composting of various wastes was carried out to create compost from various wastes for use as a nutritious soil fertilizer and to optimize waste material by employing sewage as an addition to minimize composting time and improve soil nutritional value. Four composting windrows were formed with three different types of wastes i.e. first windrow was animal waste + garden waste treated by sewage water, second windrow was food waste + garden waste treated by sewage water, third windrow was mixture of wastes treated by sewage water, and the last windrow was also mixture of wastes but treated by tap water. The compost of mixture of wastes treated by sewage water was found better than the other three windrows as having pH 8.69, Organic Content 59.25%, Moisture Content 28.09%, Carbon 27.85%, Nitrogen 0.66%, C/N ratio 42.2, Phosphorous 1.4% and Potassium 0.84%. If composting of mixture of wastes like animal waste, food waste and garden waste treated with sewage water is carried out, then it will give better results and also reduce the composting period by 30%.

Abstract (sommario):

The high nitrogen content of animal waste provides opportunities for processing to marketable byproducts and challenges for proper management to avoid harmful impacts. Technologies are being developed to conserve and utilize nitrogen as well as other valuable constituents in animal waste. Advanced treatment technologies are also being developed for housing/waste management systems that address public concerns and protect soil, water and air quality. Smithfield Foods, Premium Standard Farms and Frontline Farmers have entered into an agreement with North Carolina to develop environmentally superior technologies that meet these goals. The 18 candidate technologies are identified and three with the longest operating period, and thus most data to date are discussed. Methods for distributing this information for implementation of cost-effective technologies through the Curriculum Project and the National Center for Manure and Animal Waste Management will be presented. This work supports priority goals to conserve and utilize valuable animal waste constituents while also protecting against negative impacts.

Abstract (sommario):

Waste management in the agricultural sector has become a major concern. Increased food production to satisfy the surge in population has resulted in the generation of large volumes of solid waste. Agro-waste is a rich source of biocompounds with high potential as a raw material for food packaging. Utilization of agro-waste supports the goal of sustainable development in a circular economy. This paper reviews recent trends and the development of agro-wastes from plant and animal sources into eco-friendly food packaging systems. Different plant and animal sources and their potential development into packaging are discussed, including crop residues, process residues, vegetable and fruit wastes, and animal-derived wastes. A comprehensive analysis of the properties and production methods of these packages is presented. Future aspects of agro-waste packaging systems and the inherent production problems are addressed.

Abstract (sommario):

The article is devoted to the study of the peculiarities of waste formation during the hostilities on the territory of Ukraine. With the beginning of active hostilities in the russian federation on the territory of our country is the destruction of industrial and communal facilities, there is a mass movement of people to the western regions and abroad, disrupting natural ecosystems, leading to large amounts of waste. The classification of wastes which are generated during hostilities is presented: military, wastes from demolition and damaged buildings, household and similar wastes, wastes from destruction of industrial objects, wastes of animal husbandry, medical wastes, natural burials. The peculiarities of each of the types of waste are determined and the directions of their effective management are outlined. It is substantiated that hazardous military waste requires safe disposal by the military and the State Emergency Service of Ukraine (hereinafter – SES); it is possible to reuse the metal from the damaged military equipment. It is noted that waste from damage of buildings and industrial facilities can be divided into safe, which can be partially reused in construction, and hazardous, which require disposal. The directions of medical waste management are outlined, which are massively generated both in hospitals in relatively «quiet» regions, where the wounded are brought, and in combat zones in the provision of emergency medical care – they must be disposed of according to medical protocols. Livestock waste (dead animals and poultry, products of their vital activity) in the zone of active hostilities during the destruction of poultry farms and farms may pose an ecological danger. The prospects of their use for energy purposes – as raw materials for biogas production are determined. The terrible consequence of the war is the formation of natural burials. The necessity of exhumation and reburial of the dead in specialized. Ways to reduce the generation of household waste in regions where internally displaced persons moved en masse are proposed. An algorithm for sorting these wastes with the separation of components that can be reused during hostilities or for other purposes is presented.

Abstract (sommario):

Food waste management is a challenge in University Campuses of developing countries. This study assessed food waste management challenges in Hawassa University and the possibility of cascading the waste through biomass bioeconomy model by using interviews, observations and published and unpublished documents. The results show that so far the food leftover is being used by poor people, collected by animal ranchers or damped in an openpit. Food leftover use by poor people was challenged due to poor hygienic quality, health implication to users, insecurity to campus community and theft of property in the campuses. The university’s animal enterprise was also forced to quiet its agreement with the university due people’s competition for the leftover. Generally food waste management at the University is reactive and long-term sustainability is needed. This study suggests the cascading use of biomass, i.e. using food waste as animal feed; animal waste as feedstock for biogas generation; biogas-slurryas an organic fertilizer for university farm and plantations. If implemented the model improves the waste management practices of the University; improves the resource use efficiency and energy security, and reduces fuel wood consumption and mitigate greenhouse gas emission. Moreover the model creates circular economy that serves as a sustainability showcase in practice for research, training, recreation, experience sharing and income generation activities.

Abstract (sommario):

A sustainable animal production can improve the efficiency of animal production and recycle of animal waste, and reduce greenhouse gas emissions. It can be achieved by firstly, properly operation of animal production, such as improvement by animal breeding, synthesis of amino acids, improvement by animal nutrition, good housing design, phase feeding system, liquid feeding system, using left over of one day bakery and biscuit factory, left over of vegetable and fruit market, new methods to plant Leucaena or mulberry to feed goats, grass or fodder plant in hydroponic house for sustainable farming. Secondly, good waste management, such as transferring waste to no contaminant material and even to useful material, reduction of greenhouse gas emissions, liquid waste management, and solid waste treatment. All these subjects also need to consider the interaction between knowledge, e.g. breeding and nutrition need to consider about environmental temperature factors; waste management needs to consider about nutrient requirement by vegetable, fruit, etc. A sustainable animal production is a kind of science integrated different knowledge together, then you can achieve some good results.

Abstract (sommario):

Healthy soils are essential for progressive agronomic activities. Organic fertilization positively affects agro-ecosystems by stimulating plant growth, enhancing crop productivity and fruit quality and improving soil fertility. Soil health and food security are the key elements of Organic Agriculture 3.0. Landfilling and/or open-dumping of animal wastes produced from slaughtering cause environmental pollution by releasing toxic substances, leachate and greenhouse gases. Direct application of animal carcasses to agricultural fields can adversely affect soil microbiota. Effective waste management technologies such as thermal drying, composting, vermicomposting and anaerobic digestion transform animal wastes, making them suitable for soil application by supplying soil high in organic carbon and total nitrogen. Recent agronomic practices applied recycled animal wastes as organic fertilizer in crop production. However, plants may not survive at a high fertilization rate due to the presence of labile carbon fraction in animal wastes. Therefore, dose calculation and determination of fertilizer application frequency are crucial for agronomists. Long-term animal waste-derived organic supplementation promotes copiotrophic microbial abundance due to enhanced substrate affinity, provides micronutrients to soils and protects crops from soil-borne pathogens owing to formation of plant-beneficial microbial consortia. Animal waste-derived organically fertilized soils possess higher urease and acid phosphatase activities. Furthermore, waste to fertilizer conversion is a low-energy requiring process that promotes circular bio-economy. Thus, considering the promotion of soil fertility, microbial abundance, disease protection and economic considerations application of animal-waste-derived organic fertilizer should be the mainstay for sustainable agriculture.

Abstract (sommario):

The aim of this study is to give an overview of the production and management of animal waste in the Republic of Serbia, and to emphasize the importance of this issue and its proper solution. Disposal of animal waste is a significant prophylactic measure, aimed at detecting, preventing, suppressing and eradicating infectious and parasitic diseases in humans and animals. The process of animal waste disposal starts from the manufacturer, who is responsible for ensuring safe storage of waste in a cooling unit, until its final removal in the processing plant. Disposal of animal waste must be done in a safe way otherwise dangerous pathogens can be spread by water, air and soil and can endanger the health of the population. In the European Union, and the Republic of Serbia accordingly, the legislation was introduced regulating the ways of managing animal waste, categorizing hazardous waste and ways to its secure resolving, with member states obliged to respect and apply the methods of safe handling of by-products of animal origin.

Abstract (sommario):

Background Livestock play important economic and cultural roles in smallholder communities of Ecuador, yet they also serve as potential sources of zoonotic infections. Understanding the animal and human health concerns of smallholder farmers is important in guiding strategies for improvement of the health and livelihoods of these resource-poor farmers. Therefore, the objectives of this study were to: (a) assess the health concerns of smallholder farmers; (b) explore animal and waste management practices; and (c) identify predictors of pediatric and livestock diarrhea on smallholder farms in Ecuador. Methods This is a cross-sectional survey of 58 smallholder farmers in three communities of Chimborazo province, Ecuador. Data were collected on household demographics, smallholding characteristics, type of animals owned, human-animal interactions, health concerns, and 30-day occurrence of human as well as animal diarrhea. Summary statistics were computed and logistic models used to investigate predictors of pediatric and animal diarrhea. Results All respondents reported keeping animals. Animals kept included cattle, pigs, poultry, dogs, guinea pigs, cats, sheep, horses, rabbits, donkeys, or other livestock. More than half of the respondents named diseases as their greatest personal (55.2%) or family (58.6%) health concern, while an even greater percentage (60.3%) reported physiological stress as the primary health concern for their animals. Occurrence of diarrhea in the 30 days prior to the study was reported by 12.1% of the respondents. Additionally, 15.2% and 55.2% of the households reported diarrhea among children and animals, respectively. The majority (65.5%) of the households had toilets, while the remainder had either latrines (27.6%) or no sanitation facilities (6.9%). However, only 9.1% of the smallholdings had either a toilet (3.6%) or a latrine (5.5%) onsite and yet the farmers tended to spend most of the day at the smallholdings. Potential exposures to gastrointestinal pathogens included food- or water-borne sources (93.5% of children; 91.4% of adults) and blood-borne or fecal sources (80.4% of children; 100% of adults). Although 98.3% of the respondents kept cattle, only 27.6% had animal enclosures and even fewer (15.5%) had animal waste management plans. The odds of animal diarrhea were significantly higher (Odds Ratio [OR] = 8.7; 95% Confidence Interval [1.0–75.0]; p = .049) among households that had animal waste management plans compared to those that did not. None of the variables investigated were significant predictors of pediatric diarrhea. Conclusions Ongoing surveillance is needed to develop estimates of diarrhea incidence among smallholder families and their livestock. The impact of different animal management strategies on the potential pathogen exposure of smallholders warrants further investigations. Improving sanitation infrastructure and animal waste management strategies is recommended.

Abstract (sommario):

This article discusses the features of the application of new requirements in the field of animal waste management. From March 2023, a number of new provisions in the legislation come into force, which contribute to the transfer of animal waste from the jurisdiction of the environmental area to a new industry for the management of animal by-products.The adopted changes are aimed at increasing the efficiency of involving livestock by-products in agricultural production, including to ensure the reproduction of the fertility of agricultural land, and should help reduce the administrative burden on agricultural producers.However, the introduced norms in a number of cases leave the dual position of animal husbandry waste, keeping the requirements of environmental legislation regarding them as production and consumption waste.

Abstract (sommario):

The paper analyzes the steady trend of solar energy development, which is accompanied by the formation and accumulation of solar panel waste. This process requires the application of accomplished waste management and the development of waste disposal technologies. It was determined that the problem of waste solar photovoltaic panels becomes more urgent due to the military actions taking place on the territory of Ukraine. The general characteristics of waste for different types of panels are given. The heterogeneity of the materials of photovoltaic panels leads to an ambiguous classification and involves a combination of safe and dangerous components. It has been determined that photovoltaic panel waste can be divided into two hazard classes: hazardous waste and non-hazardous waste. The key points of solar panel waste management operations are characterized in accordance with the Law of Ukraine “On Waste Management” and EU Legislation. The main points of disposal of unusable photovoltaic panels with recovery of valuable raw materials are described. It is noted that there are significant differences in the material composition of crystalline silicon panels and thin film modules. It is noted that two processing types of PV modules are currently distinguished – coarse and fine, and the most effective steps in the preparatory stage of disposal are also determined. In general, PV panel waste disposal operations combine mechanical and chemical material extraction processes. The imperfection of the legislative and regulatory framework in the field of waste management, the increase in the ecological danger of the generation and accumulation of waste, the imperfection of the information base and waste monitoring, the insufficient development of the processes of organizing the processes of collection, accumulation and transfer of waste for disposal, the insufficiency of proposals for methods of processing and disposal of solar panels waste as a valuable resource of secondary raw materials are notable as the main problems in the field of waste management of photovoltaic panels in Ukraine. One of the main tasks for development is to increase the share of waste materials that are currently not disposed of, but can be used as secondary raw materials.

Abstract (sommario):

Technological and economic development have influenced the amount of post-production waste. Post-industrial waste, generated in the most considerable amount, includes, among others, waste related to the mining, metallurgical, and energy industries. Various non-hazardous or hazardous wastes can be used to produce new construction materials after the “solidification/stabilization” processes. They can be used as admixtures or raw materials. However, the production of construction materials from various non-hazardous or hazardous waste materials is still very limited. In our opinion, special attention should be paid to waste containing fluoride, and the reuse of solid waste containing fluoride is a high priority today. Fluoride is one of the few trace elements that has received much attention due to its harmful effects on the environment and human and animal health. In addition to natural sources, industry, which discharges wastewater containing F− ions into surface waters, also increases fluoride concentration in waters and pollutes the environment. Therefore, developing effective and robust technologies to remove fluoride excess from the aquatic environment is becoming extremely important. This review aims to cover a wide variety of procedures that have been used to remove fluoride from drinking water and industrial wastewater. In addition, the ability to absorb fluoride, among others, by industrial by-products, agricultural waste, and biomass materials were reviewed.

Abstract (sommario):

In the context of agricultural waste recycling perspectives, the article addresses the issues of its structure, approaches to classification, determining its volumes and generation processes, and waste generation coverage in statistical observations. The author offers the consideration of three classification groups of agricultural waste: crop, animal, and agrochemical waste. The low level of agricultural waste representation in official domestic statistical reports is emphasized. The methodological approaches to calculating the crop and animal waste are suggested, and agricultural waste in Ukrainian regions is calculated and mapped. The calculations show that the annual volume of agricultural waste generation in Ukraine amounts to 177.5 million tons, and only about 5 percent of them are represented in statistical reports. This situation almost eliminates the creation of an efficient public waste management system that would secure the inclusion of tens of millions of tons of crop and animal origin resources in economic turnover through waste recycling and complicates the implementation of business projects in the reuse and processing of agricultural waste. The article outlines the directions, technological forms, and reserves of primary and secondary agricultural waste recycling. It also defines three possible ways to use primary crop waste: to secure animal breeding needs, for energy purposes, and as a fertilizer. Most animal wastes are safe and low-hazard, and can be used as secondary material or energy resources. Manure plays a special role in agricultural animal waste recycling. Biologically cleaned, disinfected, or biothermally processes manure is a valuable organic fertilizer. Energy is considered to be a perspective direction of the manure use in Ukraine. The article emphasizes the importance of taking into account the competitiveness of agricultural waste recycling directions based on the general economic and environmental reasonability.

Abstract (sommario):

Agriculture and animal husbandry produce significant quantity of solid or liquid residues and waste products. Unfortunately, some of these wastes are not dealt with properly and are causing considerable damage to the environment. Agricultural wastes (AW) in Romania amount range from 7600 thousand tons a year of which only 1400 thousand tons as animal feed and 1100 thousand tons as organic manure are being utilized. These crop waste results after harvesting in the farm of leaves stem which are characterized as coarse plant by-products and big size, chemically low in protein and fat contents, or, like other country (example: Netherlands) avoid waste as much as possible, recover the valuable raw materials from any waste that is created, try to generate energy by incinerating the residual waste, and only then dump what is left. The focus of the research paper is to investigate the importance of agriculture wastes that becomes very obvious and aggregated after the harvest crops. The most common solution is the utilizations of agricultural waste for compositing, as animal fodder, most often as a source of energy, food production, by growing mushroom on agricultural wastes such as oat straw as a substrate. This means the conversion of wastes to economic, nutritional human food. Growing vegetables on oat straw compacted bales in areas where soil disease and salinity are constrains. The implementation of most of the solutions to agricultural waste management does not meet the basic elements of sustainability like environmental protection and social progression, technical and technological improvement as well as economic improvements.

Abstract (sommario):

A considerable amount of food waste ends up in centralized treatment plants due to the lack of preventive measures, resulting in significant environmental impacts. Hospitality food waste management is even more resource-intensive because of animal by-products regulation. According to this regulation, companies must store and then consign waste to specific waste managers. The extensive need for transportation of high-moisture-content materials is the leading cause of the impact. Moreover, the management of category III animal by-products is costly for companies. A previous study has shown the economic benefits of decentralized animal by-product treatment by intensive composting in catering companies. Although the produced compost was characterized by exceptional quality parameters, it was phytotoxic. The investigation of hospitality waste management is scarcely discussed among scholars, and waste management on a regional scale is nearly absent. This study examines the regional management of hospitality food waste by exploiting the municipal waste management infrastructure and intensive composting at the source. The co-maturation experiment with animal by-products and municipal green waste primary composts showed that the phytotoxicity parameters of the cured compost were in the optimal range or below the thresholds (conductivity (1.1 mS cm−1), dissolved organic carbon (82 mg kg−1), and NH4+/NO3− ratio (0.0027)). Additionally, the amounts of total nitrogen, water-soluble nitrogen, and water-soluble phosphorus in the compost were rated as very high. Finally, inventory and environmental impact analysis of the current and planned management approaches showed a reduction in 12 of 18 impact categories.

Abstract (sommario):

Solid waste disposal is a major challenge in many industrialized and developing nations, both in metropolitan regions as well as rural ones. The collection and disposal of municipal solid waste (MSW) is a serious issue facing metropolitan areas in many nations today. An effective MSW management strategy must satisfy all of these criteria: financial viability; technical feasibility; social and legal acceptability; and ecological friendliness. Small and large cities alike have a major difficulty in dealing with solid waste management. One of the current study topics is the valuation of food organic waste. Existing waste disposal methods include the typical landfill, incineration, composting, and other methods of handling solid waste. Composting and anaerobic digestion have traditionally been the most widely employed methods for the treatment and exploitation of the organic part of MSW (AD). The amount of organic solid waste (OSW) being generated globally is rising at an astronomical rate. Agricultural waste, domestic food waste, human and animal wastes, etc. comprise the majority of OSW. They're often used as animal feed, disposed of in landfills, or burnt. OAWs are made up of protein-, mineral-, and sugar-rich components that may be employed as substrates or raw materials in other processes.

Abstract (sommario):

This study compares biogas production from cattle dung, piggery faeces and poultry wastes under different environmental conditions by anaerobic digestion as a means of managing municipal solid wastes and was conducted in the Department of Biological Sciences, Benue State University, Makurdi from 1st August, 2011 to 13th December, 2011. A 6 Kg of each of waste was mixed with four litres of water and loaded into three locally constructed digesters. The biogas produced was measured using water displacement method after every 5 days. The result indicated that piggery feaces gave the highest yield of biogas (1.07 L/kg), followed by cattle dung (0.71 L/kg), with poultry wastes the least (0.42 L/kg) all under direct sunlight. This study shows that piggery droppings are the best substrate for biogas production and the best yield result when the process is carried out under direct sunlight. However, statistical analysis showed no significant difference in the biogas yield of these feed stocks at 5 % level of significance. Anaerobic digestion is recommended to be explored as an environmentally friendly technology for organic waste management.

Abstract (sommario):

Maggot comes from the Black Soldier Fly insect which is very active in eating a variety of organic waste. Maggot is able to process organic waste up to 52.2 kg per day. Indonesian waste dominated by organic species is 40 million tons in 2019 where 17.94% is produced by traditional markets (7 million tons). Based on BPS data, Traditional markets produce 1 ton of waste per day. By the ability of maggot to process waste, a 60 x 40 meter building is needed. Aside from being an organic waste solution but also as a producer of maggot with high protein, maggot flour and compost, it will add economic value. Organic waste production in Indonesia which continues to increase has the potential for maggot production to be continuous so that it can replace fish meal or conventional animal feed in terms of continuity. Maggot has a crude protein content of 42% so it is very good as a substitute for fish meal which is always imported. Maggot is also thought to have potential as a substitute for the MBM ration. Research shows that maggot flour can replace 75% of fish meal as an abdominal ration. The compost produced by maggot also has a greater NPK value than Em4 and cow dung, so that it has the potential to become a quality NPK fertilizer. It can be concluded maggot as an organic waste solution and potentially as a substitute for conventional sustainable feed.

Abstract (sommario):

Healthcare wastes are generated in facilities whose activities are related to human or animal healthcare. Wastes with high infectious potential risk to human health and the environment must be managed carefully, from generation to its final disposal. However, there is an absence of consolidated data addressing the healthcare waste qualitative classification generated by hospitals of a large city. Therefore, the present study aims to characterise qualitatively the high infectious waste generated by hospitals from Belo Horizonte city, Brazil, whose Health Services Waste Management Plan were approved and certificated by the municipal cleansing autarchy. Differences in the types of infectious wastes generated in maternity hospitals were identified ( p 0.034), when compared with general ( p 0.189), low ( p 0.549) and high complexity ( p 0.619), which can be explained owing to the extended hospital activities. This information suggests a similar profile of the qualitative generation of infectious wastes by hospital categories, as expected. The largest generation and diversity of high-infected wastes are associated with a greater variety of activities provided. The segregation can be considered as the main step in healthcare waste management, therefore, it is concluded that the correct classification leads to a better understanding of all those involved in the healthcare waste management.

Abstract (sommario):

Medical waste is waste generated in medical and health institutions and poses a risk to those who created, packaged, stored, transported, treated and performed the disposition. The management of medical waste is an organized process that consists of five elements: separation; identification; handling; treatment and disposition. Clinical waste is defined as 'any waste which consists wholly or partly of human or animal tissue, blood or other body fluids, excretions, drugs or other pharmaceutical products, swabs or dressings, syringes, needles or other sharp instruments'. This type of waste may prove hazardous to any person coming into contact with it unless it is rendered safe. Waste is defined as 'hazardous' when the waste itself or the material or substances it contains are harmful to humans or the environment. The other main waste stream is known as offensive waste, which primarily contains waste that is considered unpleasant due to its appearance and smell, for instance incontinence waste. Management of whole medical waste requires strict control and monitoring from the spot of occurrence, until its final storage. Each health institution should tend to reduce the amount of medical waste, meaning to organize and control the generating of the bio-hazardous waste as well as to organize and control the action of collection, transportation and destruction of the waste.

Abstract (sommario):

Animal waste can serve as a raw material source for feed preparation, and can also be used, after appropriate processing, as fuel, fertilizer, biogas, and other useful products. In addition, the practical use of these wastes eliminates their mandatory disposal. Recycling animal waste is a feature of the circular economy, leading to environmental sustainability. In this regard, we conducted a search and review of contemporary scientific publications from open sources, including publications and data from Internet portals, Web of Science, Scopus scientometric databases, websites of patent offices, libraries, and reading rooms. It has been found that animal by-products are desirable for use in combination with vegetable protein sources. The 15 most relevant types of animal waste and their use are indicated based on current scientific publications. Moreover, 13 types of feed of animal origin, along with their purposes and descriptions, are also identified. Current scientific publications and research on the processing of insects into feed; the use of bird droppings, meat, and bone and bone meal; and the processing of seafood waste, bird waste, and eggshells are reviewed. As a result, firstly, the most important types of technological equipment involved in animal waste processing technologies, particularly devices for drying, grinding, and mixing, are analyzed and discussed. Secondly, technologies for processing waste into useful products of animal origin are analyzed and discussed.

Abstract (sommario):

A considerable part of food is wasted, causing investment capital loss as well as environmental pollution and health problems in humans. Indirect solar drying was applied to test the potential of drying and reusing this waste as a component of animal feed. The effect of weather changes on drying kinetics and the effective diffusion coefficient, dried feed nutritional composition, and microbiological analysis of the dried product were investigated. A convective laboratory dryer was used as a reference method. Weather conditions have a crucial effect on the use of solar drying; one sunny day with appropriate conditions can reduce the water activity of food waste to below 0.3 and moisture content to below 6%. Much better fitting of experimental and model drying curves was achieved considering sample shrinkage, applying a more complex solution of Fick’s second law combined with an optimization procedure. The studied food waste had a good combination of nutrients, such as protein, fat, and carbohydrates; however, the amount of protein in the dried food waste was found to be lower than that in regular feed, and therefore, adding a protein source is recommended. Autoclaving of fresh samples reduced the total microbial counts of dried samples by more than 50%.

Abstract (sommario):

Environmentally friendly options for waste disposal and the need for expansion and diversification of the national and international energy matrix are relevant issues today. One technique that supports these goals is anaerobic biodigestion, which generates clean energy from biomass. Accordingly, our goal was to perform a quantitative and qualitative assessment of scientific publications on biodigestion in order to understand the evolution of the technique, which is essential for environmental and economic sustainability. Ninety-nine articles indexed in the Scientific Electronic Library Online between 1980 and 2015 were evaluated. The results showed a significant increase in scientific publications since 2000 which addressed, in addition to environmentally friendly waste management, the energy issue, with the use of biogas. This increase in the number of publications coincides with increased awareness on natural resource management and concern about global energy management. Most of the articles involved a general evaluation of the process, using mainly animal waste from pigs, and emphasizing biodigestion as waste management, since pig farming produces a large volume of waste and has a high environmental impact.

Abstract (sommario):

Frozen shrimp and fish are the second most valuable export items from Bangladesh. Thus, in processing industries, a considerable amount of seafood waste is produced every year. Neglecting seafood waste leads to serious forms of wastage. The purpose of this survey-based study was to estimate the amount of seafood waste produced and understand the existing waste management practices in Bangladesh. Potential for seafood waste-based silage production and its utilization were also studied. Across the seafood industry, around 43,321 tons of seafood waste are produced every year. The highest amount of seafood waste is produced in Khulna, followed by Chittagong, Cox’s Bazar, Dhaka, and Sylhet. Local people consume a portion of fresh shrimp carapace and heads and gills of large fish. A portion of seafood waste is also used to feed aquaculture species. Moreover, parts of dried shrimp shells, appendages, and fish scales, air bladders, and fins are exported to some Asian countries. The prospect of fish silage production constitutes a promising new development for animal feed production in Bangladesh. The availability of waste materials from seafood processors and the demand from feed millers favor the conditions for silage production. However, in order for the seafood waste-based silage industry to flourish, the establishment of supply chains for seafood waste and end products (silage) is required. Studies on growth performance, muscle quality, and digestibility of animal feed with silage-based diets are required for farmed species.
