Energy generation and revenue potential from municipal solid waste using system dynamic approach

Area of Science:

• Environmental Science
• Engineering
• Economics

Background:

• Municipal Solid Waste (MSW) generation increases with economic growth in developing nations.
• Composting and waste-to-energy are emerging as sustainable alternatives to landfilling in India.
• Effective MSW management is crucial for minimizing environmental impact and securing local energy resources.

Purpose of the Study:

• To develop a system dynamic (SD) model for predicting energy generation, treatment, and cost analysis of MSW in India up to 2030.
• To evaluate the potential of MSW for energy and compost production.
• To analyze the economic viability of MSW treatment facilities.

Main Methods:

• Development of a system dynamic (SD) model.
• Forecasting electrical energy generation potential from MSW.
• Estimating compost production rates.
• Analyzing revenue generation and budget requirements for MSW treatment.

Main Results:

• Electrical energy generation potential is predicted to rise from 58,380 MWh in 2007 to 319,875 MWh by 2030.
• Compost production is projected to increase from 45,000 tonnes in 2006 to 390,000 tonnes by 2030.
• Predicted revenue from MSW treatment is expected to reach Rs. 2569 million (33.4 million USD) in 2030, exceeding expenditures.

Conclusions:

• The developed SD model demonstrates the significant potential for energy and compost generation from MSW.
• MSW management through waste-to-energy and composting can become economically self-sustaining by 2030.
• The SD model offers a valuable tool for enhancing municipal solid waste management systems.
