In Colombia, the issue of waste discharges derived from the tanning process to water bodies is a scenario that has been widely documented. However, measurement exercises have failed to identify improvements in this process that integrates administrative knowledge with concepts of labor, social and environmental welfare. The present article is the culmination of research conducted within the framework of the project “Estudio comparativo de la administración y las repercusiones socio-ambientales en las empresas del sector de curtiembre. Case Bogotá (Barrio San Benito), Case Barranquilla and Case Villapinzón (Cundinamarca)” (Comparative study of the administration and the socio-environmental repercussions in tanning sector companies. Case Bogotá (Barrio San Benito), Case Barranquilla and Case Villapinzón (Cundinamarca)) concerning the administrative practices and the negative effects derived from the absence of management systems for negative externalities caused to the environment by companies in the tanning sector. The study was developed as follows: initially, a systematic documentary review of the laws, decrees and regulations that have a direct or indirect impact on the tanning sector was carried out, followed by field work using data collection instruments (questionnaires) in the San Benito neighborhood (Bogotá), in the town of Villapinzón (Cundinamarca) and in the city of Barranquilla (Atlántico), where there are formal and informal work clusters dedicated to the leather industry. The objective of this study was to identify the relationship between administrative styles and formal processes of strategic planning activities development with the adoption of dumping control systems and other aspects related to environmental management, oriented to the organizational level. Based on the above, the information was analyzed with emphasis on those companies with a common denominator in their control strategies in relation to those policies that were the result of administrative and business practices and that finally led to the desired effects in the social, environmental and economic spheres. Finally, the discussion section focuses on the recognition of these good practices and the possibility that they could be replicated by other actors on the global level.

The Leather Industries occupies a place of prominence in the Indian economy in view of its massive potential for employment, growth and export. There has been increasing emphasis on its planned development aimed at optimum utilization available raw material for maximizing the returns particularly from exports. This paper aims at understanding the impact of tanneries waste disposal on environment. From the very beginning of industrialization in India, tanning industries have been playing a significant role in the country’s economy. Due to its importance as a labor based export oriented industry the full flourish of this industrial sector is essential. But due to the absence of proper waste management, using inferior technologies, lack of facilities for treating industrial wastes; the tanning industries especially located in Vellore district are aggravating environmental problems day by day. The discharging and dumping of wastes near the water bodies without treatment makes it almost look like an area which is lying under the blanket of pollution. It is an emerging problem not only for the environment but also as the social context of the country. This study focuses on the tanneries located in Vellore District to assess the present situation arising from such activities and proposed several mitigation measures.

Availability of quality freshwater is one of the most critical environmental issues of the twenty first century (UNEP, 2002). Urbanization leads to the environmental pollution, i.e., urban growth leads to the increasing of slums, solid waste disposal, provision of transport facilities, conjection and groundwater contamination. Groundwater is an important water resource for domestic and agriculture in both rural and urban parts of India. Pollution of groundwater comes from many sources. Groundwater contamination in a major issue, especially in industrial areas especially like Dindigul. The presence of large number of tanniers and allied industrial unit such as dyeing and bleaching units in and around the town are the main factors, which affect the environmental quality of the town. Dindigul town is not having the physical expansion since 1981 with an area of 14.01sq.km. Only wards are increased by enjoying the rapid growth of population. Dindigul is the main industrial hub for the Tanneries. Effluents from the tanneries are discharged in to streams which drain into ponds, thereby polluting the ground water sources and cultivable land. These values are more than the permissible limit in and around the tannery cluster compared to other parts of the area. The pH,CO3, Na, Ca, Mg, NO3, and SO4 values of all groundwater samples are within the permissible limits but all the EC, TDS, HCO3and K values are exceeding the permissible limit. According to TH and Cl 6 samples are exceeding the prescribed limits. There are about 80 tanneries spread within 4-6 kms radius in the south western part of the town i.e., near Paraipatti, so ground water pollution is very high compared to other places. Madurai road tanneries are located so in Begampur near Annamalayar school pollution is high. R. M. Colony is having the highest household wastages because of its vertical expansion so in that areas also pollution is high.

One of the most urgent environmental problems today is the pollution of the environment by emissions of harmful substances and industrial waste. The negative impact on the environment and people is becoming more widespread, and its disposal methods inhibit the development of the economic system. In a market economy, entrepreneurs are not interested in increasing environmental costs, which naturally lead to higher production costs and reduce profits. The impact on the environment is becoming more widespread every year and has led to an ecological crisis in some parts of the world. Waste recycling has been constantly discussed since a person “produces” more than 250 kg of household waste per year. At the enterprise, these figures reach 10 000 kg. In recent years, Ukraine has imported about 30-50 thousand tons of PET granulate, which is gradually accumulating in landfills in the form of packaging, bottles, films. Such hazardous pollutants affect the environment through soil and water. In contrast, Ukraine does not yet have successful experience in waste management. In our opinion, such behavior is the ignorance of the population about waste disposal and replacement of a particular product with a more environmentally friendly one. The functioning of enterprises and farms does not always have the equipment to dispose of waste, and there is no room for the disposal of unnecessary products and raw materials. However, the problem of lack of innovative equipment arises due to a lack of adequate funding. Therefore, the lack of possibilities for a comprehensive solution to the situation creates a barrier, which does not allow to take proper measures to eliminate and reduce the amount of garbage. Despite many regulations and legal frameworks for regulating waste management, there is no cost-effective policy, and there is no regional waste management program and plan for their proper disposal. It can be concluded that the recycling and disposal of waste will reduce the need for waste incineration, create conditions for improving the economic component of the region and the country as a whole with an account of environmental quality standards. The paper pays attention to the essence of waste disposal; identified ways to recycle garbage.

From a circular economy perspective, the recovery and reuse of waste plays a fundamental role. Foundries purchase hundreds of millions of siliceous sands every year to create molds and cores that give shape to the casting. These sands, after several uses, become waste that must be properly recovered or disposed of; they are called waste foundry sands (WFS). The reuse of WFS leads to a reduction in: (i) the consumption of raw materials; (ii) the emissions into the atmosphere; and (iii) the amount of waste sent to landfill—on the other hand, the impact that their use generates on the environment and human health must be carefully assessed. Leaching tests are a fundamental tool for establishing the hazardousness of a waste and its release of contaminants into the environment. This paper presents an analysis of the scientific literature regarding the chemical characteristics of WFS and their release following leaching tests carried out in the laboratory; the environmental standards adopted by the countries that have issued guidelines regarding the reuse of WFS will also be presented.

Studies on comparison of principal factors between CAER (China Actual Environmental Risk) and CZER (China Zero Environmental Risk) from Behavior Angle are seldom found, so we studied the theme above in this thesis. By analysis, we have known that on one hand, there are such aspects in common as natural cause, production action, living action, production waste disposal, and living waste disposal between CAER and CZER. On the other hand, they are different in such aspects as Government surveillance only for CAER, and public management and market management only for CZER. And our related advice is as follows: first, careful protection of natural environment. Secondly strict surveillance on production of waste from such behaviors as enterprise production and human living action by market management, public management, and Government surveillance, etc.. And thirdly great encouragement to arouse interest in technological innovations friendly with the environment in waste disposal, etc..

Annually, increasing volumes of industrial and municipal waste generation and disposal, leading to increasing anthropogenic environmental and sanitary-epidemiological pressure on the environment and, as a consequence, significant environmental damage and associated economic damage to natural ecosystems, represent one of the main threats to environmental safety territories, life and health of the population. At the same time, numerous valuable components extracted from processed production and consumption wastes can be an important source of reserve for the development of industries and sectors of the economy, entrepreneurial activities in the use of secondary resources for production, services, works and energy. This factor dictates the need to search for new sound management, economic, organizational and technical approaches and solutions to lawmaking, planning and forecasting the cost-effective organization of the system of separate collection, processing, disposal, disposal of production and consumption waste, the development of an appropriate industrial, scientific and technological infrastructure, increasing the share of secondary material and energy resources extracted from waste, the development of instruments of state oh support and economic incentives for this activity.

Landfills have become the main environmentally sound form of final disposal of urban solid waste and when properly managed, do not cause harm or risks to public health. The objective of this work was to perform an analysis of the environmental quality of the Landfill in Campina Grande / PB, in order to verify if the landfill meets the technical standards and environmental requirements. In the analysis of the data collected were used, as reference, the standards NBR 8,419 (ABNT, 1992) and NBR 13,896 (ABNT, 1997). From the analyzed data, it was verified, that the landfill presents technical and operational conditions for the employees to work and an operability that makes possible the accomplishment of the activities in a satisfactory and environmentally safe way. Thus, the studied area is appropriate for the waste disposal activity according to NBR 8,419 (ABNT, 1992) and NBR 13,896 (ABNT, 1997). However, improvements are suggested for the internal access routes, since, because they are not paved, it may hinder the passage of trucks that discharge the waste on days of intense rain.

Every year around the world, tanneries valorize and ennoble about 8 million tons of raw hides and skins, a waste material from the agri-food supply chain that would otherwise be destined for disposal in landfills or incineration, resulting in the release of about 5 million tons of greenhouse gases. On the other hand, leather, an extraordinary example of valorization and conversion of a putrescible and polluting material, has a much longer use life than its substitutes and a far more favorable degradative fate for the environment. The war in Ukraine and the consequent repercussions on the international market are likely to further exacerbate the historic need for raw materials (crude and semi-finished) of the European and, in particular, of the Italian tanning industry; and tanneries in non-European (Asian and South American) countries, given the greater availability of raw hides and skins, could take advantage of this to reduce the competitiveness of EU tannery in the markets. So worrisome is the situation that one of the world's most important associations of tanning industrialists, the National Union of the Tanning Industry (UNIC-Unione Nazionale Industria Conciaria), in agreement with the European Confederation of Tanners (COTANCE), has planned, in the first months of the year 2022, to request the European Commission to limit the export of European raw/semi-processed hides and skins outside the EU borders. In such a disturbing scenario, there is a clear need to adopt countermeasures projected over the medium and long term and adequate investments, for the ever-increasing implementation of the principles of circular economy and technological innovation in order to improve the environmental, but also economic, sustainability of the leather industry.

Information systems MRP, ERP or ERP II and is now the standard used in many enterprises. Many of these companies also has a statutory obligation to monitor and report information about the waste. For this purpose, they become extremely useful environmental information systems in the enterprise. These systems can lead to a measurable positive economic impact in the enterprise. In addition, legislation in Poland forced by the municipalities need to organize collection system and waste disposal. The introduction of the so-called junk reform enabled municipalities to enable the use of information systems to inform about the dates of the waste collection, including mobile technologies. The article presents the use of IT systems in managing the economy of municipal waste.

The snow and glacial ice on permanent snowfields must serve as both the water source and the receptacle for wastes for any human habitation. In addition, the snow also serves as the support media for any structural foundations and hence the thermal aspects of water supply and waste disposal can be critical. Most activity has occurred on the ice caps of Greenland and Antarctica and has ranged from small transient field parties to large permanent facilities in continuous use for over 25 years. Novel procedures to insure the reliable production of good quality water are described as well as the recommended criteria for water quantity depending on the size and duration of the activity. The various methods of wastewater disposal that have been used at temporary camps and permanent stations are described along with the results from studies that defined the fate of the wastewater following its discharge to the snow. Such definition is important to insure protection of the water supply as well as the thermal integrity of any structural foundation. Key words: water supply, water quality, sewage waste disposal, ice cap, glaciers, snowfields.

Since 2017, a housing renovation program has been implemented in Moscow, which is a unique program aimed at settling and demolishing shabby low-rise housing stock and new construction on the vacated territory. The renovation program raises a fundamental issue of construction waste disposal. Many current technologies of building mass demolition imply dusting of adjacent territories, have low efficiency in transporting construction waste generated in this process and lead to environmental problems resulting from its disposal, so the rational use of construction waste becomes one of the environmental protection's main points. In this research, we address the question: how the principle "Green Digital Technologies," reflected in the Moscow development concept "Smart City," which is a part of the housing renovation program in Moscow, is currently implemented. Three implementation ways of this principle have been revealed: contraction of "smart houses" under the renovation program according to smart 1.0 standard; use of BIM-technologies in the program; use of "smart demolition" technology. It is proposed to consider the process of recycling construction waste after demolishing old houses under the renovation program according to the principles of sharing and circular economy to increase the program's environmental friendliness and reduce environmental risks for the Moscow population.

Recycling building demolition waste in addition to environmental benefits is also economically interesting. In addressing the environmental issues it is recommended to give priority to recovery and rational utilization of waste with regard to their basic characteristics before disposal respectively storage. Issue of the use of recycled materials in concrete structures and their disposal in the world and in our longer pays much attention. Use and recycling of construction materials is a great asset for more prospective and progressive methods of construction waste utilizations. The program focused on waste management is therefore necessary to reconcile economic and environmental aspects in order to come to an optimal solution of the issue of waste and environmental protection.

After decades of turmoil and international sanctions much of the key civil infrastructure within Iraq has fallen into disrepair, leading to a considerable decline in the provision of basic and essential municipal services. This is particularly true of waste and resource management services that have seen years of underdevelopment and deterioration. This has resulted in a lack of provision of basic public services in the waste sector which have been replaced by a burgeoning unregulated informal market in waste collection, disposal and recycling. In response, a National Solid Waste Management Plan (NSWMP) for Iraq was developed in 2007, to plan for the strategic development of all aspects of waste management in the country over the coming 20 years. In particular, the NSWMP focuses on policy development and integrated planning regarding regulatory framework, economic aspects, institutional capacity, citizen and technical education, and technical and operational development. This paper summarizes the key objectives, challenges and subsequent recommendations contained in the NSWMP for Iraq.

To preserve the ecological balance and health of the population of the African continent, it is necessary to maintain the cleanliness of the surrounding rivers, lakes and ocean coasts. Oil production, transportation of oil and petroleum products inevitably lead to pollution of sea waters due to accidents on tankers, equipment breakdowns, and fires. Oceanic coasts are of great importance for the development of the tourism industry, which plays a significant role in the national economies of African countries. However, many coastal areas are contaminated with industrial and household waste, oil refining waste and sewage. As a result of the growth of cities, the increase in the number of urban residents and the development of industry, a huge number of substances that do not decompose naturally is discharged into water sources. Currently, domestic sewage in most coastal cities does not meet modern sanitary requirements, since the repair of old and the laying of new sewage treatment plants require large financial investments. In the interests of nature and human health, a number of international instruments has been adopted prohibiting the import of hazardous and radioactive waste, as well as the dumping or incineration of hazardous waste in the oceans and inland waters on the African continent. In some African countries, periodic clean-up activities are carried out on ocean and river coasts, but they are ad hoc and do not have a decisive impact on the state of contaminated areas. Experts of international environmental organizations have proposed a set of measures for the conservation and rational use of water resources: construction of wastewater treatment plants; mandatory environmental assessment of all major water management projects; development of measures to eliminate possible damage; control of new industrial installations and industrial waste disposal; design and operation of landfills based on reliable hydrogeological information and environmental expertise. However, these regulations are often violated, and solving the problem of coastal water pollution remains a distant prospect.

The production of municipal solid waste (MSW) represents one of the greatest challenges currently faced by waste managers all around the world. In Brazil, the situation with regard to solid waste management is still deficient in many aspects. In 2015, only 58.7% of the MSW collected in Brazilian cities received appropriate final disposal. It was only as late as 2010 that Brazil established the National Policy on Solid Waste (NPSW) based on the legislation and programmes established in the 1970s in more developed countries. However, the situation with regard to MSW management has changed little since the implementation of the NPSW. Recent data show that, in Brazil, disposal in sanitary landfills is practically the only management approach to MSW. Contrary to expectations, despite the economic recession in 2015 the total annual amount of MSW generated nationwide increased by 1.7%, while in the same period the Brazilian population grew by 0.8% and economic activity decreased by 3.8%. The article describes the panorama with regard to MSW in Brazil from generation to final disposal and discusses the issues related to the delay in implementing the NPSW. The collection of recyclable material, the recycling process, the application of reverse logistics and the determination of the gravimetric composition of MSW in Brazil are also addressed in this article. Finally, a brief comparison is made between MSW management in Brazil and in other countries, the barriers to developing effective waste disposal systems are discussed and some recommendations for future MSW management development in Brazil are given.

The paper discusses the results of a study on the use of fundamentally new equipment (rotary knife mill) for the preparation of secondary fiber waste in the air and the possibility of their full use in finished products for various purposes. In order to justify the effectiveness of the preparation and the feasibility of using secondary wood fiber semi-finished products by a dry grinding method, the physical phenomena and regularities of the mechanism for the preparation of secondary wood fiber semi-finished products by the proposed method are determined and investigated, which characterize the technological process of preparation in air and their possible future use as semi-finished products or in the manufacture of finished products products. The process of dissolution of wood fiber waste was studied, the mechanical effect on wood fiber waste due to face-cross cutting (cutting, crushing, flattening, breaking) and aerodynamic phenomena (breaking, collision, dissolution, fibrillation), contributing to the formation of external and internal fibrillation of the secondary wood fiber, is described. increase in specific surface in the absence of high temperatures and pressure, without the addition of chemical additives, without the use of water and steam. The performed studies allow us to propose a new method and system for the preparation of wood fiber waste by dry grinding, justifying their economic and environmental feasibility.

Purpose – This paper examined the current status of municipal solid waste management across Nigeria. The core aspects covered are generation, characterization, collection, scavenging, open dumping, disposal and environmental implications of poor solid waste management. The purpose of this paper is to present a comprehensive overview of the current state of municipal solid waste management in Nigeria. Design/methodology/approach – This study was executed by a combination of an extensive literature search and field study. Solid waste generation rates for 31 Nigerian cities were obtained from literature. In addition, characteristics of municipal solid waste from 26 Nigerian cities were also obtained from literature. Other aspects such as characterization of solid waste obtained from final dumpsite and heavy metals accumulation in solid waste dumpsites were undertaken first hand. Findings – Solid waste generation rate was found to vary from 0.13 kg/capita/day in Ogbomosho to 0.71 kg/capita/day in Ado-Ekiti. Factors affecting solid waste generation rates were identified. Typically, food waste was found to constitute close to 50 percent of overall municipal solid waste in Nigerian cities. This study shows that the rate of generation of plastics, water proof materials and diapers has assumed an upward trend. Due to the dysfunctional state of many municipal waste management authorities, many cities have been overrun by open dumps. For instance, more than 50 percent of residents of Maiduguri in northern Nigeria and Ughelli in southern Nigeria dispose of their waste in open dumps. Indiscriminate disposal of waste has also resulted in the preponderance of toxic heavy metals in agricultural soils and consequent bioaccumulation in plants as well as groundwater contamination. Research limitations/implications – The main limitation of this research is municipal waste management authorities do not have relevant data. Hence, there was heavy reliance on published materials. The status of waste management in Nigeria is very deplorable and therefore poses serious threats to public and environmental health. There is urgent need for both government and individuals to adopt holistic and sustainable waste management strategies in order to safeguard public/environmental health. Practical implications – Findings from this paper can form a veritable resource for the formulation and implementation of sustainable municipal solid waste management framework and strategies in Nigeria. Originality/value – While most studies on municipal solid waste management in Nigeria are focussed on selected cities of interest, this particular study cuts across most cities of Nigeria in order to present a broader and holistic view of municipal solid waste management in Nigeria. The paper has also unraveled core municipal solid waste management challenges facing Nigerian cities.

Pakistan, an agricultural country, raises 146.5 million commercial and domestic poultry birds, which generate around 544,831 tons of waste per year. This waste finds its final disposal in agricultural land as soil fertilizer or disposal site amendment. The usage of poultry litter for this purpose is uncontrolled, which results in environmental degradation such as emission of greenhouse gases, e.g., methane. However, alternative options such as thermochemical conversion of poultry litter can offer better solutions where this waste can be used as a low-cost carbon source for the synthesis of Multiwalled Carbon Nanotubes (MWCNTs). In this study, efforts were made to utilize this cheap and plentiful carbon source for the synthesis of CNTs in the presence of Ni/Mo/MgO as a catalyst, through pyrolysis. For a better yield of carbon product, the optimum ratio for the catalysts (Ni/Mo/MgO) was found to be 4:0.2:1. Furthermore, the process parameters were also optimized for better carbon yield. A good yield of CNTs resulted from a pyrolysis time of 12 min, a temperature of 825 °C, and a catalyst weight of 100 mg. The structure and morphology of the produced nanotubes were confirmed through X-ray Diffractometer (X-RD) and Scanning Electron Microscopy (SEM). The environmental application of the nanotubes was tested in a synthetic chromium solution in the lab using a batch experiment. Different experimental conditions (pH, adsorbent dosage, and contact time) were optimized to improve the adsorption of Cr (VI) by carbon nanotubes and a UV-Visible spectrophotometer was used at 540 nm to measure the absorbance of Cr (VI). The results showed that up to 81.83% of Cr (VI) removal was achieved by using 8 mg of CNTs at pH 3 with 400 rpm at 180 min of contact time. Thus, it was concluded that poultry litter can be a useful source for the synthesis of MWCNTs and thereby removal of Cr (VI) from industrial tanneries’ wastewater.

Improper management of municipal waste has become a growing concern globally due to its impact on the environment, health, and overall living conditions of households in cities. Waste production has increased because households do not adopt waste management practices that ensure sustainability. Previous studies on household waste management often considered socio-economic aspects and overlooked the environmental and behavioral factors influencing the disposal practices and health status. This study adopted four constructs, defensive attitude, environmental knowledge, environmental quality, and waste disposal, by employing a structural equation modeling approach to explore research objectives. Data from 849 households of the Islamabad-Rawalpindi metropolitan was collected by using a multi-stage sampling technique. The structural model results showed that the two constructs, environmental knowledge and defensive behavior, positively affect household health status. The most significant health-related considerations are waste disposal and environmental quality, both of which negatively impact health status and do not support our hypothesis. The results provide valuable perspectives to enable households to engage actively in waste management activities. The findings indicate that understanding the intentions of household health status drivers can assist policymakers and agencies in promoting an efficient and successful community programmes related to sustainable solid waste management by allowing them to foster how the desired behavior can be achieved.

The principles of selection and creation of rational methods of disposal and recycling of wastes are based on the fact that the problem of waste is an interconnected environmental-economic and technological problem, and the waste itself should be considered as technogenic raw materials of complex organo-mineral composition. Therefore, the main purpose of the work is to define methods for recycling waste and their environmental aspects. To achieve this goal, the methods of analysis, spectroscopy were used. It is determined that the final treatment of waste, to date, means either their disposal in a landfill or incineration, which adversely affects the environment. Methods for identifying the material of the object, as well as algorithms for the selection and recognition of objects by processing data from the computer vision system are considered. High accuracy is shown in 94.12% identification of plastic polymers.

Anthropogenic geoecology was developed at the end of the 20th century, but continues to face challenges in an integrated methodological approach to assessing the pollution of territories with long-term consequences of natural resource extraction. The consequences of extraction and primary processing of natural raw materials are the lack of effective control over the territories once the ore mining is completed. In order to develop effective methods to control the development of hazardous natural and man-made processes in the areas of inactive waste disposal facilities, it is necessary to analyze a sufficiently large set of data, including the condition of ground and surface waters, soils, flora, the efficiency of waste disposal facilities protection from direct or indirect impact on the natural environment. Research on modeling the processes of transfer and accumulation of pollutants includes a general assessment of the direction of man-made flows and selection of vegetation for phytoremediation of territories along the boundaries of the facilities as well as the direction of pollutant migration. The impact of mining facilities (dumps, tailings reservoirs) is directly correlated with the time of their existence, the toxicity and the rate of transformation of the components contained, the economic efficiency of their further utilization or conservation. Thus, the methodological approach to the rehabilitation of environmentally disadvantageous areas in places where mining and primary processing of resources is completed requires integration of several techniques and methods to assess the existing environmental situation. It also includes the speed and direction of its evolvement, and the economic assessment of damage to the natural environment. The introduction of tested recovery techniques will prevent the expansion of territories with irreversible destruction of geosystems, which led to a complete loss of productivity of the reproducing resources.

This paper firstly reviews the microbiological aspects of the accumulation of xenobiotic and non-xenobiotic substances from industrial and domestic waste water treatments, with particular reference to hydrocarbons, pesticides and inorganic plant nutrients. The paper goes on to argue that if water bodies are to be used to establish recreational fisheries as well as for water supply and effluent disposal, then the management aim may need to be one of controlled eutrophy. Ramifications of this proposal are considered. The biological aspects of the impact of other recreational and amenity uses of water bodies on water and environmental quality is briefly described. The paper concludes by discussing the training required by potential water managers.
