Informing energy justice based decision-making framework for waste-to-energy technologies selection in sustainable waste management: A case of Iran

Municipal solid waste (MSW) is an energy source that should not go untapped or unutilized. The waste must be properly utilized through combustion, anaerobic digestion, and landfill gas acquisition, as it represents material and energy content. This will reduce the effects of global warming, which is as a result of high concentration of carbon dioxide, methane, and other greenhouse gases (GHGs), in the atmosphere. This chapter focuses on the technologies for solid waste management and the thermodynamics involved in the process for sustainable and cleaner energy. The equations presented represent the thermal efficiency, conversion efficiencies, as well as possible work that can be derived from a power plant utilizing MSW as fuel. It is important that countries in Sub-Saharan Africa vigorously pursue sustainable waste management technologies, especially recycling and landfilling, while exploring and investing in waste-to-energy technologies that will perform optimally using the composition of the waste in Sub-Saharan Africa in the design of the waste-to-energy technology.

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.

The City

The City of Taunton, MA (City) has undertaken a competitive procurement process to consider proposals for a private company to develop, design, permit, finance, construct and operate a Solid Waste Management Facility (SWMF), which may be sized up to 1800 tons per day (TPD), to serve both the City’s and region’s needs for long term solid waste management. A comprehensive Request for Qualifications and Proposals (RFQP) for the SWMF was issued in June 2008. The City initiated the procurement process because its current landfill is scheduled to reach capacity in 2013. The procurement process focused on conversion technologies capable of recovering materials and producing electricity or fuels, and maximizing diversion of waste from landfilling. Technologies considered included both traditional and emerging technologies; e.g., composting, co-composting, thermal gasification, aerobic and anaerobic digestion, hydrolysis and mechanical means of waste separation into useful products. Landfilling and traditional waste-to-energy technologies were not considered.
