Estimation of Energy Consumption and Environmental ECO-Costs of Compost Production from Municipal Solid Waste in Rasht

According to technology progress and the increase in human populations since the Industrial Revolution, the amount of waste generated is increasing. With the increase in waste production, due to problems and challenges such as emissions from waste, require to sustainable management of waste has increased. One of the methods of waste management is to use it for the production of compost. In this study, the composting plant in Rasht was investigated, with a daily input of around 400 ton of MSW. Of this 400 ton of waste, 64.1 percent is the organic material, that 48 percent (192 ton) after the processing is separated from the MSW and sent to the fermentation location, and finally 12 ton compost is produced. The amount of energy consumed at this plant, after calculating the input and output energy, was about 82.02 GJ. Energy productivity index was calculated as 0.15 ton/GJ. Environmental ECO-costs for the entire composting process were obtained as 4.92×107 Rial.
