Paradigm for solid waste containment to active treatment and energy recovery

Project: Research project

Project Details

Description

Approximately 250 million tons of municipal solid waste (MSW) is generated on a yearly basis in the United States. In 2010, 54% of the generated waste was landfilled, while 34% was recycled and 12% was incinerated. Both recycling and incineration have limitations in handling large volumes of waste and are only feasible for certain types of waste. Among the landfilled MSW, 60% consisted of paper, food and yard wastes by wet weight. These organic wastes are in general economically or technically unfeasible for recycling and incineration, and are biodegradable under anaerobic conditions in landfills. Therefore there is major need to develop a targeted and sustainable strategy for handling such types of waste.

MSW biodegradation prior to and after landfilling can be affected by various operations 'from bin to grave.' These include source separation, temporary storage, collection and transportation, pretreatment, co-disposal or co-treatment with other waste streams, and biodegradation enhancement in landfills.

The degree of biodegradation of MSW determines its energy generation and recovery potential. However, there is a lack of complete understanding of the overall MSW biodegradation process and the factors influencing it at each step. Current waste management practices are often not optimized and energy recovery is not emphasized. Economic analysis is largely absent due to insufficient knowledge and data. Fei's research targets impacts to the MSW biodegradation process prior to and after landfilling due to various operations.
