Abstract (sommario):

As the population grows there is an increase in wastage from our economic activities. Causing pollution on land, water, air, and on all other living things. India, being the second largest populous country in the world produces enormous organic and inorganic waste. While the household and agriculture waste may be used immediately after simple treatment, the waste generated from industries cannot be used as it is. If the industrial leftovers are effectively recycled or retreated by adopting suitable management techniques, then there will be no unwanted element in the environment. Rather, all nutrient elements if recycled, may enrich soil and other natural resources. Scientists and economists have found new technology to treat all waste as a source through recycling, conversion, source of energy, and land reclamation. Now, they have come to the conclusion that waste is a waste if untreated, but if it is modified in some other form, it is a potential resource and a wealth for our future. However, the only requirement is that it should be treated properly or taken care of. This paper examines some of the technology adopted by scientists, economists to use the waste as one of the potential resource either through knowledge or any other means for increasing productivity, maximising returns, and reducing pile up of unused waste. Successful case studies have been reviewed and analysed critically.

Abstract (sommario):

The growth of the population is related to urbanization, development, and industrialization. There found a strong correlation between population, industrialization, and waste production. The famous thermodynamics laws offer insights into the technological/marketing impact on waste production and energy conversion processes. The conventional methods such as land filling, combustion, gasification, incineration, etc. not enough to manage such a huge volume of waste. The non-segregation tendency, consumerism nature makes this waste management work problematic. The paper studies the natural efficiency in the waste management system and also the inability of traditional technology's to handle rapidly increasing waste volume. The plasma-based waste technology is similar to the natural waste management cycle, but with high volume capacity in a short duration. This also has a scope of waste to energy (WtE) conversion. Though plasma has high installation and maintenance costs, revenue generation from byproducts like syngas and slag will create it financially viable.

Abstract (sommario):

Current building management standards demand that construction waste management occurs in the planning phase. This paper presents the development of a plug-in as a BIM tool to predict waste generation. As a research strategy, the plug-in was applied to a single-family housing project, the respective construction wastes were predicted in the BIM technology and compared to the literature. Through waste generation indexes, some planning indicators were calculated. The identified wastes were automatically classified, and a management structure was designed. The study showed that the best results are obtained when the construction waste is estimated from Actual Built Volume instead of Apparent Constructed Volume like the traditional models uses. In conclusion, adopting a plug-in do predict construction waste has proved to be advantageous. A specific advantage of the proposed method is that the plug-in user may adopt their waste generation indexes according to the regional and the production team aspects. The adoption of a plug-in made the acquisition and processing of data fast and versatile.

Abstract (sommario):

In cities where a large geographical area of the city is densely populated, the process of waste collection is cumbersome, tiresome and expensive. Often, the burden of manually tracking and collecting of waste causes waste management companies enormous wasted effort and get them involved in tasks that are not necessary. No doubt, a digital interaction between waste management companies and targeted waste collection areas could ensure the process becomes fast, efficient and traceable as they become aware of the states of the wastes, aptly. It will considerably reduce any discrepancies that may occur due to the lack of information available during a particular time. Accordingly, this paper proposes a novel approach towards waste management combined with the internet of things to reduce the problems that would occur due to the accumulation of wastes and hence improvise waste collection/management process. Additionally, an innovative feature which generates revenue and creates business opportunities for waste management companies is introduced via advertisement solution based on network-attached storage technology.

Abstract (sommario):

This study aims to study the waste management process and recycling of municipal waste in Tehran. Currently, Kahrizak is the defined landfill area which collects the waste generated from 22 districts of Tehran. The organic wastes undergo to the windrow composting method in order to manage the partial of the waste generated in the city. Samples from the compost pile generated in Kahrizak were examined to evaluate its fertilizer value to be used further by the farmers. The results show that the obtained compost does not reach the acceptable quality to be used further in agriculture, due to lack of homogeneity, aeration and presence of heavy metals. Overall, it has been concluded that, due to the improper waste segregation and management prior to sending to landfill and presence of non-organic materials such as hazardous metals and medical wastes, causes difficulties in proper waste management, implementation and producing high quality compost. Based on this study the existence of stakeholders, society, economy and proper handling rules can effectively improve the waste management system in the country and leads to the sustainable green environment.

Abstract: Urban India generates tones of wastes annually. Our country faces major challenges related with waste management. Conventional garbage collection is not efficient since authorities are not notified until waste bin is full, and this leads to overflow of waste material. Efficient way of waste disposal and collection of disposed garbage is crucial for a sustainable and clean India. This paper presents smart waste management using IoT based waste bin for collection and monitoring level of waste inside bin. system is applied using two ultrasonic sensors which is being controlled by Node MCU. One of ultrasonic sensor detects level of waste in bin and or detects person approaching bin to dispose waste. This detection helps in automatic opening and closing of lid. Servo motor is connected to lid which assists action of closing and opening of lid. In this system, level of waste in bin will be sent to concerned authorities. IoT data is kept and observed using Blynk app. offered system is reliable, cost effective and can be implemented.

Abstract (sommario):

The problems concerned with waste management abound in most regions of the world, and so, efforts must be made to assess the global level of pollution and to understand the major factors involved in order to propose efficient waste treatment technologies. This must be compatible with environmental and economic conditions and appropriate to semi-urban settlements, isolated communities and a variety of industrial situations. The main purpose of this paper is to present recent waste management technology as an alternative solution to traditional treatment systems in regions where those systems are not economically or technically feasible, using for this purpose the advantages of climatic conditions (air temperature, relative humidity and wind speed). This integrated technology combines two different processes: optimization of the solid/liquid separation, using a decanter, followed by the utilization of evaporation panels to eliminate the liquid fraction of the effluent, optimizing by this way the evaporation phenomenon, which is so important and resolute in certain cases, that it is absurd not to exploit it intensely. The technology presented was followed by a research programme developed in the last three years, implemented in an agro-industrial unit located in a high polluted area of Portugal, with the aim to evaluate its efficiency and optimize the performance parameters. The conclusions of this research programme emphasized the importance of the evaporation phenomenon as a simple solution to deal with complex environmental problems.

Abstract (sommario):

Recently, there are many problems caused by global environment warming. The limited natural resources require efficient methods and systems for recycling and processing of the wastes for a better environment. One of the problems today is the processing of the kitchen garbage, because when they become in large amounts in small areas, the natural capacity of the environment cannot assimilate them. Therefore, construction of the recycling systems is needed to save the resources and minimize the wastes. For this reason, in this paper, the authors have proposed and implemented a waste management robot system, which can change the kitchen garbage to compost. Then, the compost can be mixed with the ground and used for growing of vegetables and other plants. The proposed system uses the information network, sensor technology and robot technology. The authors present in this paper, the implementation of the proposed system and evaluate its performance by experimental results.

Abstract (sommario):

Households in developing countries are the primary waste generators. Therefore, this study aims to identify the composition and factors responsible for household solid waste generation. It also studies the current status of household waste management in India and strategies for waste minimisation and management. Findings revealed that household waste is heterogeneous. The urban household produces substantial amounts of waste, and vegetables and food waste are major components. Family size has either a positive or negative impact on waste generation. A higher-income household with more purchasing power has a clear positive impact on waste generation. People living together share food items and consumer goods, so fewer food scraps, leftovers, and packaging wastes are there. With advanced education, household wastes are higher, whereas households with secondary education produce the least waste. There is an accumulation of fresh graduates but few are aware of current environmental issues. Municipalities are responsible for collecting and disposing of solid waste, but at present, they focus mostly on the collection part, while innovation in waste treatment is scarce. Nevertheless, a few cities in India have taken a positive approach to the selection of waste management strategies. Also, household solid waste can be converted from burden to resource by sensitising people to segregate waste at the source and following sustainable strategies.

Abstract (sommario):

As more studies were conducted and global events unfold, a greater emphasis is being placed on the importance of preserving the Earth's natural resources and cycles before we face a catastrophic climate crisis. Thus, developed countries are constantly adapting their policies and legislation to promote green development for the sake of sustainable development, which benefits both the environment and the socioeconomic segment. As populations grow and living standards improve, more waste is generated. Appropriate municipal waste management is necessary to avoid harm to the environment, wildlife, and human health. Sustainable municipal solid waste management is even included in the United Nations' (UN) Sustainable Development Goals, which aim to improve the world's environment and economy. The European Union (EU) member states' waste management systems can be considered exemplary. In some countries, landfills have been prohibited, promoting the use of more sustainable technologies such as organic waste incineration, recycling, and composting. However, a divide exists between member countries, with some lagging behind in terms of waste management strategies. Thus, this paper examined the current state of municipal waste in EU member states, followed by a review of the various disposal technologies implemented. The difficulties and environmental concerns that must be overcome are discussed, as are the recommendations and possible future directions.

Abstract (sommario):

The present paper discusses the role of earthworms in recycling of sugar industrial wastes. The wastes generated from sugar industry are pressmud, bagasse, bagasse fly ash, sugar cane trash, sugar beet mud, sugar beet pulp, molasses etc. These wastes when mixed with other organic substrates become ideal mixtures for growth of earthworms. These wastes if stored in open field’s causes contamination in the environment and may cause several diseases in public health. But the governments have been unable to tackle the menace of solid waste pollution due to dearth of appropriate technologies, finance and space. Therefore, environment friendly and cost effective technologies for nutrient recycling or remediation of wastes are being advocated as an alternative means for conserving and replenishing natural resources of the ecosystems. Vermicomposting is one such technology that synergises microbial degradation with earthworm’s activity for reducing, reusing and recycling waste materials in a shorter span of time. Earthworm technology can convert sugar industrial wastes into valuable fertilizing material. The final product (vermicompost) produced during the process of vermicomposting is nutrient rich organic fertilizer with plant available nutrients such as nitrogen, potassium, calcium and phosphorus. In the present study an attempt has been made to document the role of earthworms in reuse of sugar industry waste.

Abstract (sommario):

Food is essential to our survival, yet the Food and Agriculture Organization of the United Nations (FAO) estimates that about 820 million people were undernourished in 2018. In this context, food waste generation is a particularly salient issue. Wasting food means missing opportunities to feed the growing world population and consuming scarce resources, such as land, water and energy used in the production, processing, distribution and consumption of food. Firms in HORECA (hospitality, restaurant and catering) represent a considerable share of total food waste and, more importantly, are characterized by an overall low sense of awareness about the sustainability-oriented innovation opportunities and challenges of minimizing food waste. This article draws on an in-depth case study to explore the use of technological advancements in downstream value chain. This case study draws on a tech startup providing services for HORECA companies to address a new way for companies to solve the food waste challenge. Adopting technological innovations to quantify and minimize wastage via collaborations with third-party companies can be a strategic and cost-effective way to supplement a company’s open innovation activities.

Abstract (sommario):

Across the world, any activity associated with the nuclear fuel cycle such as nuclear facility operation and decommissioning that produces radioactive materials generates ultramodern civilian radioactive waste, which is quite hazardous to human health and the ecosystem. Therefore, the development of effectual and commanding management is the need of the hour to make certain the sustainability of the nuclear industries. During the management process of waste, its immobilization is one of the key activities conducted with a view to producing a durable waste form which can perform with sustainability for longer time frames. The cementation of radioactive waste is a widespread move towards its encapsulation, solidification, and finally disposal. Conventionally, Portland cement (PC) is expansively employed as an encapsulant material for storage, transportation and, more significantly, as a radiation safeguard to vigorous several radioactive waste streams. Cement solidification/stabilization (S/S) is the most widely employed treatment technique for radioactive wastes due to its superb structural strength and shielding effects. On the other hand, the eye-catching pros of cement such as the higher mechanical strength of the resulting solidified waste form, trouble-free operation and cost-effectiveness have attracted researchers to employ it most commonly for the immobilization of radionuclides. In the interest to boost the solidified waste performances, such as their mechanical properties, durability, and reduction in the leaching of radionuclides, vast attempts have been made in the past to enhance the cementation technology. Additionally, special types of cement were developed based on Portland cement to solidify these perilous radioactive wastes. The present paper reviews not only the solidification/stabilization technology of radioactive wastes using cement but also addresses the challenges that stand in the path of the design of durable cementitious waste forms for these problematical functioning wastes. In addition, the manuscript presents a review of modern cement technologies for the S/S of radioactive waste, taking into consideration the engineering attributes and chemistry of pure cement, cement incorporated with SCM, calcium sulpho–aluminate-based cement, magnesium-based cement, along with their applications in the S/S of hazardous radioactive wastes.

Abstract (sommario):

<abstract> <p>The world is today faced with the problem of plastic waste pollution more than ever before. Global plastic production continues to accelerate, despite the fact that recycling rates are comparatively low, with only about 15% of the 400 million tonnes of plastic currently produced annually being recycled. Although recycling rates have been steadily growing over the last 30 years, the rate of global plastic production far outweighs this, meaning that more and more plastic is ending up in dump sites, landfills and finally into the environment, where it damages the ecosystem. Better end-of-life options for plastic waste are needed to help support current recycling efforts and turn the tide on plastic waste. A promising emerging technology is plastic pyrolysis; a chemical process that breaks plastics down into their raw materials. Key products are liquid resembling crude oil, which can be burned as fuel and other feedstock which can be used for so many new chemical processes, enabling a closed-loop process. The experimental results on the pyrolysis of thermoplastic polymers are discussed in this review with emphasis on single and mixed waste plastics pyrolysis liquid fuel.</p> </abstract>

Abstract (sommario):

AbstractSeveral European waste management organizations have started work on creating a technology platform to accelerate the implementation of deep geological disposal of radioactive waste in Europe. There is an increasing consensus in the international community about geological disposal as the preferred option for solving the long-term management of spent fuel, high-level waste and other longlived radioactive wastes. At the same time, European citizens have a widespread desire for a permanent solution for high-level radioactive waste disposal. A majority of European countries with nuclear power have active waste-management programmes, but the current status and the main challenges of those programmes vary. The most advanced waste management programmes in Europe (i.e. those in Sweden, Finland and France) are prepared to start the licensing process of deep geological disposal facilities within the next decade. Despite the differences between the timing and the challenges of the different programmes, there is a joint awareness that cooperation on the scientific, technical and social challenges related to geological disposal is needed, and that it is beneficial for the timely and safe implementation of the first geological disposal facilities. Such a demonstration of a viable solution for the management of high-level radioactive waste will enhance stakeholder confidence in Europe. It is envisaged that a technology platform would enhance European cooperation in this area. The platform will provide a tool for reducing overlapping work, to produce savings in total costs of research and implementation, and to make better use of existing competence and research infrastructures. From 2008, SKB (Sweden) and Posiva (Finland) led the preparation work to set up the implementing geological disposal of radioactive waste technology platform (IGD-TP). Since then other implementers from France, Germany, Switzerland, United Kingdom, Spain and Belgium have joined the project. To date a strategic research agenda for the platform has been prepared and consulted upon, which is now the basis for taking the platform into a deployment phase.

Abstract (sommario):

Urban construction works produce wastes of mud, silt and silts. Through an environmental economic analysis of the waste disposal and an investigation of the existing management mode, it can be seen that the managements of those waste in Shenzhen--instead of regarding those as resource--are more for imminent discharges which results in the waste of soil and the pollution of the environment. Based on the idea of ecological sustainability, this paper puts forward a mode for the overall process of managing the construction wastes in Shenzhen, which can be divided into four aspects: reduction at source, optimization of the transportation, comprehensive utilization and efficient disposal. In the end, the paper brings up a management mechanism suitable for the overall process from the perspectives of technology, legislation, management and social awareness.

Abstract (sommario):

The municipal solid waste management (MSWM) is one major concern in Cambodia due to complicated problems from waste sector. Until now, because of poor MSWM, solid wastes have produced high pollution, like methane (CH4), nitrous oxide (N2O), and carbon dioxide (CO2), which are the substances of greenhouse gas affect to climate change. Therefore, this study was undertaken to estimate and compare the greenhouse gas (GHG) emission from municipal solid waste in different cities namely; Phnom Penh, Battambang, and Siem Reap of Cambodia. GHG emission was calculated through Intergovernmental Panel on Climate Change (IPCC) calculator 2006 based on secondary data of 2009 for all cities. In order to reduce the GHG emission, four scenarios were proposed with different waste treatment technologies such as composting, anaerobic digestion, waste reduction at landfill by separating waste for recycling before disposal off in landfill, and landfill with gas recovery as well. Additionally, the multiple benefits of implementing the proposed scenarios may include reduction of GHG emission, promotion of energy saving for landfill operation, and promotion of the renewable energy concept like electricity.

Abstract (sommario):

The main characteristics of the European environmental policy are reviewed. Focusing on EU policy on waste, the paper presents the principles on which EU waste management is founded, particularly the waste hierarchy. In this hierarchy, priority shall be given to prevention of the generation of wastes and of its hazardousness. Secondly, the reuse and the recovery of materials (recycling), which implies the separation of waste at source involving consumers in the scheme of waste management. Priority should be given to material recycling over energy recovery. The less desirable option is the disposal of waste. The paper reviews specific directives on organic waste management, following the scheme of the waste hierarchy, together with the general trends observed in producing common regulations for all types of organic residuals. Afterwards, key issues and measures for the implementation of a feasible strategy for organic residuals management, e.g. quality requirements and quality assurance, are discussed. Finally, there is a view from a manager's perspective on the current EU policy, public acceptance and suitable waste management operations.

Abstract (sommario):

Abstract: In the electronic industry, e-scraps or e-wastes refer to electronic goods that are discarded or unneeded. About 50 million ton of e-wastes are produced every year. Depending on their reactions, there might be potential danger. E-wastes, such as computer batteries and other electrochemical waste, may cause unwanted results, so it is important to consider them along with physical wastes. India generates about 1.5 lakh tons of e-waste annually, and almost all of it ends up in the informal sector as there is no organized alternative. It is well documented that humanity's capabilities were enhanced by the industrial revolution. However, the revolutionary changes experience by societies across the globe due to the application of electronics are deeper and more widespread than the impact of the industrial revolution. Human society has been profoundly changed by the electronics age and has become more connected than ever before. Electronic items have contributed to smoother communication, economic growth, and job opportunities. However, in addition to the positives, technology has brought to light a number of concerns, such as the growing problem of ewaste, which society must confront head on. In the existing situation, it is always possible that human health and the environment would be in trouble. If coordinated legislation and activities for efficient e-waste management and disposal were not enacted. This paper aims to provide a quick overview of the relatively new notion of e-waste, its production in India, and the associated environmental and health implications. It emphasizes the booming informal and nascent official e-waste recycling economies, as well as the urgent need for more explicit legislation and a forward-looking strategy. The paper also examines global e-waste trading and international experience in this area. There is also a list of references at the conclusion for further reading. Each year, hundreds of thousands of consumer electronics, computers, monitors, phones, printers, televisions and other portable devices become outdated and were mainly dumped to the landfills or poorly recycled. Recent technological development and growing demands for new and better functioning electronics accelerate the amount of electronic waste (e-waste) worldwide, making it to be one of the fastest growing streams in many countries. The estimated lifespan of electronics is about three to five years because of the increasing rates of consumption, new developments and urbanization.

Abstract: Waste proliferation has increasingly become a serious concern of municipal authorities in recent times, especially for developing countries and municipalities. This paper presents the composition of municipal solid wastes generated in the Yenagoa metropolis and dumped in the Yenagoa Central waste dumpsite, Bayelsa State Nigeria. The character of the municipal solid waste was determined in terms of the composition of individual waste in the waste stream using average mass (kg) and percentage composition by mass of the various components using electronic weighing balance. It was found that 53.125% of the solid waste generated in the study area was made up of organic waste. Out of this percentage, food waste was the most abundant with 32.38% by mass. Vegetable waste recorded 5.8% composition by mass. Paper and Textile recorded 6.5% and 6.38% respectively. Wood waste had 2.13% composition by mass. While the percentage of inorganic waste within the waste stream was 46.875% in the following order, Plastic and nylon bags recorded 20.38% by mass of the total waste stream. Bottles, leathers, ceramics and construction wastes recorded 8%, 1.38%, 1.13% and 5.63% respectively. Electronic waste recorded 6.75% composition by mass. Metals, Cans and Battery wastes recorded 0.75%, 2% and 0.25% respectively. Finally, medical waste recorded 0.63% composition by mass. It is recommended that adequate financial provision, proper waste legislation, training and re-training of staff and full community participation in waste management should be encourage. Formal composting and recycling facilities should also be setup to enhance adequate management of waste. Keywords: Municipal Solid Waste, Characterization, Proliferation, Composition.

Abstract (sommario):

In response to the RCRA land ban regulations and TC rule promulgated by the U.S. Federal Environmental Protection Agency (EPA) in 1988-1990, an Integrated Refinery Waste Management (IRWM) program has been developed to provide cost-effective solutions to petroleum industry customers. The goal of IRWM is to provide technology based remediation treatment services to manage sludges and wastewaters generated from the oil refining processes, soils contaminated with petroleum distillates and groundwater contaminated with fuels. Resource recovery, volume reduction and waste minimization are the primary choices to mitigate environmental problems. Oil recovery has been performed through phase separation (such as centrifugation and filtration) and heating of heavy oils. Volume reduction is achieved by dewatering systems such as centrifuges and filter presses, and low temperature thermal treatment. Waste minimization can be accomplished by bioremediation and resource recovery through a cement kiln. In-situ vapor extraction has been applied to remove volatile organic compounds from the vadose zone in contaminated sites. Stabilization has been effective for soils contaminated with heavy metals and nonvolatile substances. For the listed hazardous wastes generated from the refining process, a combination of liquid/solids separation and thermal treatment has been successfully applied. The sludge from the on-site ponds or continuous operations is pumped to a surge tank before heating, phase separation and volume reduction by a two-stage centrifuge system. The first stage horizontal centrifuge has effectively separated the solids from the liquid phase containing oil and water. The oil in the liquid phase is separated from the water in the second stage vertical centrifuge and is recycled back to the refinery for re-use. The water will be sent back to the wastewater treatment system for further treatment. Pretreatment of the wastewater may be required.
