[Characteristics and influence factors of the energy consumption and pollutant discharge of municipal solid waste transfer stations in Beijing].
In this study, we investigated characteristics and influence factors of energy consumption and pollutant discharge (ECPD) of municipal solid waste transfer stations (MSW TSs) in Beijing by assessing four parameters including the amount of waste recycled, leachate production, water consumption and electricity consumption, based on three years' average data of MSW TSs in Beijing obtained through field investigations from 2009 to 2011. Meanwhile, integral performances of the stations with and without garbage sorting capacities (Sorting TS and Compressing TS) were also analyzed. Results showed that MSW TSs in Beijing differ greatly. For each ton of MSW, masses of waste recycled, leachate productions, water consumptions and electricity consumptions generally fall in the ranges of 12.9 kg x t(-1), 5.8-49.0 kg x t(-1), 40. 3-156.7 kg x t(-1) and 1.75-5.60 kWh x t(-1), respectively. Despite overall the higher energy consumption and more pollutant discharge than Compressing TS, Sorting TS could achieve waste reduction and reuse by recycling part of the municipal solid wastes, as well as the optimization of process by sorting wastes into different ingredients for corresponding waste disposal plants, which could reduce heavy burdens of landfills and extend their lifespans.
