Slaughter House

Presently the slaughter houses of khulna city corporation (KCC) area in Bangladesh are being used in such a way that the wastes come from these are polluting the surrounding environment such as river water, solid surface, air etc. In this circumstance, the research analyzed the management options of this slaughter house wastes and determines how this process would be suitably managed through the community participation. To fulfill the above mentioned objective, the research work was conducted through the questionnaire survey, direct observation, face-to-face interview along with the random sample collection and relevant measures of different factors. The research finding reveals that the total quantity of waste produced from these slaughter houses was 2888.45 tonnes/year. The management of this volume of waste was found as unsatisfactory by the most of the stakeholder groups due to fail of the conservation of public health and ecosystem of the local community. However, the analysis of the research data and other relevant information suggest that the potential management system such as a zero waste management of the wastes of slaughter houses in Khulna City Corporation area is possible to implement for more environmentally friendly development of the society which have the potential to resource reuse (waste-to-energy recovery) and others. Finally, the research recommended three separate designs of the conventional biomethanation plant and a potential biogas production model for these slaughter houses.

The Impact

Waste is a valuable commodity and remains a livelihood source for waste pickers in the global South. Waste to Energy (WtoE) is often described as alternative to landfilling, as it provides cheap fuel while making waste disappear. In some European cities, this method has evolved into an impediment, slowing down the adoption of more sustainable technologies and waste prevention. These plants typically strain municipal budgets and provide fewer jobs than recycling and composting, thereby inhibiting the development of small-scale local recycling businesses. We applied the idea of ‘waste regime’ with an interdisciplinary and situated lens to provide insights to the following questions: How do different political developments in Brazil and Sweden, frame and reframe waste incineration and energy recovery, in the context of sustainability and waste management on local, regional and national levels? What forms of resistance against WtoE exist and what are the arguments of these protagonists? We evaluated the impact of WtoE and compare it with other waste management options with regard to CO2 balances and general environmental and social impacts. We conclude by suggesting more socially and environmentally appropriate ways of waste management, particularly for the context of global South cities.

Abstract Waste is a valuable secondary carbon resource. In the linear economy, it is predominantly landfilled or incinerated. These disposal routes not only lead to diverse climate, environmental and societal problems; they also represent a loss of carbon resources. In a circular carbon economy, waste is used as a secondary carbon feedstock to replace fossil resources for production. This contributes to environmental protection and resource conservation. It furthermore increases a nation’s independence from imported fossil energy sources. China is at the start of its transition from a linear to circular carbon economy. It can thus draw on waste management experiences of other economies and assess the opportunities for transference to support its development of ‘zero waste cities’. This paper has three main focuses. First is an assessment of drivers for China’s zero waste cities initiative and the approaches that have been implemented to combat its growing waste crisis. Second is a sharing of Germany’s experience—a forerunner in the implementation of the waste hierarchy (reduce–reuse–recycle–recover–landfill) with extensive experience in circular carbon technologies—in sustainable waste management. Last is an identification of transference opportunities for China’s zero waste cities. Specific transference opportunities identified range from measures to promote waste prevention, waste separation and waste reduction, generating additional value via mechanical recycling, implementing chemical recycling as a recycling option before energy recovery to extending energy recovery opportunities.

Global Capacity

In this study, United States, China, India, United Kingdom, Nigeria, Egypt, Brazil, Italy, Germany, Taiwan, Australia, Canada and Mexico were selected to represent the global community. This enabled an overview of solid waste management worldwide and between developed and developing countries. These are countries that feature most in the International Conference on Solid Waste Technology and Management (ICSW) over the past 20 years. A total of 1452 articles directly on solid waste management and technology were reviewed and credited to their original country of research. Results show significant solid waste research potentials globally, with the United States leading by 373 articles, followed by India with 230 articles. The rest of the countries are ranked in the order of: UK > Taiwan > Brazil > Nigeria > Italy > Japan > China > Canada > Germany >Mexico > Egypt > Australia. Global capacity in solid waste management options is in the order of: Waste characterisation-management > waste biotech/composting > waste to landfill > waste recovery/reduction > waste in construction > waste recycling > waste treatment–reuse–storage > waste to energy > waste dumping > waste education/public participation/policy. It is observed that the solid waste research potential is not a measure of solid waste management capacity. The results show more significant research impacts on solid waste management in developed countries than in developing countries where economy, technology and society factors are not strong. This article is targeted to motivate similar study in each country, using solid waste research articles from other streamed databases to measure research impacts on solid waste management.

Zero Waste is a strategy offering waste management solutions for today’s businesses. The Zero Waste strategy has been created with the objective of stimulating sustainable utilisation of resources, production and consumption with the highest possible level of recycling of generated waste. Due to the fact that currently there is very little information and only few relevant data available as a base for the implementation of the Zero Waste strategy, waste management specialists approach and apply such a strategy in different manners. On the other hand, there are areas of waste management where such a strategy has already been applied on a long-term basis in spite of non-existing relevant legislative tools. Indicators determined in the Zero Waste strategy may be achieved only if the individual countries clearly define legislative environment and adopt a national Zero Waste strategy with achievable objectives unambiguously determined. The area of waste separation, or handling of fractions of waste non-utilisable as secondary materials after separation, is one of the areas directly connected to the Zero Waste strategy. The objective of this paper is the evaluation of the usage of fractions of waste non-utilisable as secondary materials for energy recovery, providing thus valuable knowledge and information for the implementation of the Zero Waste strategy.

Waste To Energy

Thermal technologies, such as gasification, pyrolysis, waste-to-energy (WTE), and advanced thermal recycling (second generation WTE with the most advanced air emission control system), can be employed to recover energy from municipal solid waste (MSW), reduce the volume of material to be landfilled, and lessen the potential emission of methane. Methane is a potent greenhouse gas and a major component of landfill gas. All operating WTE facilities in the United States have been subjected to strict environmental regulations since the passage of the Clean Air Act Amendments in 1990. As a result, U.S. WTE facilities now meet or exceed stringent local air quality standards, including those imposed by the South Coast Air Quality Management District (SCAQMD) in Southern California. The United States Environmental Protection Agency (EPA) recognizes the important role of WTE in the integrated solid waste management and ranks combustion higher than landfilling in its solid waste management hierarchy. In addition to upstream source reduction and recycling, downstream thermal treatment of the residual MSW (conducted in controlled environment) can effectively recover energy and further reduce waste volume. Despite all the advantages and environmental benefits of thermal technologies, its utilization for treating MSW in California still faces many challenges. These include negative public perceptions, economical disadvantages, local marketability of by-products, and disposal options for residuals. This paper discusses the need to include energy recovery in the integrated MSW management in California and the challenges encountered by many local jurisdictions.

Use Of Resources

The environmental impact and potential for utilization of the billions of tons of used products and materials discarded each year by humanity is immense. The sheer magnitude of the materials and complexity of waste management and reuse make the issue of quantifying impacts and best practices all the more difficult. In recognition of this task, the Earth Engineering Center (EEC) of Columbia University and the Environmental Engineering Group of North Carolina State University combined resources in 2008 to form a research organization that is focused on defining and promoting best practices for sustainable waste management. This is the Center for Sustainable Use of Resources (SUR; wwwSURcenter.org) and its mission is to quantify the greenhouse gas emissions and other life cycle impacts of various “waste” management practices; and use this information for advancing the best practical means for managing used materials, in the U.S. and globally. The SUR Center builds on the strengths of past research at Columbia and North Carolina State on recycling, composting, waste-to-energy, and landfilling. This paper describes some of the research work completed and underway at the Center.
