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.

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.

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.

Waste Conversion

The technology selected by the Los Angeles Bureau of Sanitation for its new waste-conversion facility marks an unprecedented step forward in sustainable waste management. Developed by Green Conversion Systems (GCS) in Rye, New York, the proposed facility utilizes commercially-proven waste-treatment technologies which combine the proven benefits of a conventional materials-recycling facility (MRF) with technologies developed for the newest generation of waste-to-energy (WTE) facilities operating in Europe. As a result, the proposed plant will convert essentially all of the waste into electrical power and recyclable byproducts. In the plant design developed by GCS, “black-bin” (post-curbside recycling) waste collected by the City of Los Angeles is treated in a two-step process: • An advanced materials-recovery facility recovers almost 30 percent of the waste for recycling. • The remaining waste is processed in an advanced WTE facility which produces electrical power and a range of commercial byproducts. • More than 99 percent of the waste treated will be diverted from landfilling. When the plant becomes operational, it will provide waste disposal at reasonable costs and several hundred direct and indirect jobs for the surrounding community.

Resource Circulation

In light of the growing attention to the need for establishing a lifecycle-oriented circular economy and to promote resource circulation to maximize the utilization of limited resources, this paper presents a case study on setting-up new national-level indicators and targets in accordance to the shift in the national waste management paradigm from waste treatment to resource circulation, which is being initiated in multiple countries around the world. Specifically, using the case of Korea, which recently implemented its new Framework Act for Resource Circulation, this study illustrates the process for setting new indicators and projecting Korea’s waste management based on the indicators developed in this study. The five main indicators suggested are the final disposal rate, actual recycling rate, waste to energy recovery rate, resource circulation rate, and resource productivity, and their precise definitions and calculation methods and the necessary revision in national statistical data collection for obtaining the required data for the indicators are discussed. For the effective delivery of the policies in the long term, the annual targets for the indicators and overall strategies for promoting resource circulation are proposed based on the predictions for future population growth and waste generation. With continuous effort from 2018 to 2027, it is expected that Korea will be able to reduce its final disposal rate from 8.7% to 3.0% and increase its actual recycling rate from 76.4% to 82.0%, waste to energy recovery rate from 6.95% to 12.66%, resource circulation rate to 14.0% to 16.4%, and resource productivity to 630 USD/ton to 1900 USD/ton.

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.

Recovery System

The elevation of waste generation subsequent to population growth has become a severe environmental topic in Malaysia. Since most of the waste is being dumped into a landfill, the open dumpsite, or unsanitary landfills which are not constructed with proper engineering plan, severe impacts on the environment result. The energy demand in Malaysia increased with the growing population, but reliance on fossil fuels to generate electricity has created another greenhouse gas contributor. Alternatively, waste-to-energy technology solves the problem of increasing waste by converting the waste to a renewable energy source. Malaysia has moved towards landfill gas recovery system and incineration for waste energy recovery. The recovery system and refuse-derived fuel plant achieved expectation; however, the incineration plants have failed due to the opposition of the public, lack of funding and technician expertise, and other technical issues. The solid waste management practices lacking separation and recycling sources, become an obstacle for development. The government puts effort into solving the current issue by promoting recycling in the public, enforcing the legislation, and approaching new technologies for better solid waste management practice in the future. This paper aims to discuss the application of energy recovery from municipal solid waste in Malaysia.
