Included activities starts

This activity starts with the waste treatment plant receives municipal solid waste

Included activities ends

At the end of this activity, the waste is treated, and specific waste emissions from the landfill are released into the environment (air due to landfill gas leaks, water due to leachate from the waste, and subsequently into groundwater).

Description

The dataset represents the waste management activity of \"municipal solid waste\" in a sanitary landfill. The recommended use of this dataset: for average municipal/public waste mixtures. It is not suitable to represent any single specific waste, such as plastics, paper, cardboard. The characteristics of municipal solid waste in Zhangye City, Gansu Province, are as follows: food waste 36.38%, paper 9.7%, rubber 11.34%, textile (fiber) 2.1%, wood/bamboo 1.36%, ash soil 0%, brick/tile/ceramics 37.81%, glass 0.93%, metals 0.23%, others 0%. Moisture 44. 26%, Higher Heating Value (HHV) 6088.2 kJ/kg, Lower Heating Value (LHV) 4390.57 kJ/kg. The carbon fraction of the initial waste, i.e., 60.4% biogenic. The proportions of metals in the waste not oxidized and largely recoverable (excluding extremely small or extremely thin components): Iron: 60.03%; Aluminum: 17.81%; Copper: 72.83%. Overall degradation rate of waste over 100 years: 18.73%. Degradability of waste fractions: Paper: 27%; Mixed Cardboard: 32%. 4% plastics: 1%; laminated materials: 18%; laminated packaging, such as drink cartons: 18%; composite products, such as diapers: 18%; glass: 0%; textiles: 12%; minerals: 0%; natural products: 27%; compostable materials: 27%; inert metals: 10%; volatile metals: 0%; batteries: 0%; electronics: 0%; landfill gas capture and utilization generated 5.52E-05 kWh of electricity and 1.99E-01 MJ of useful heat.

Technology comment

This is an inventory for a sanitary (controlled) landfill for municipal solid waste. The final average landfill height is 20 meters. The duration of the operation phase is 30 years. The landfill gas collection and utilization for this waste begins one year after disposal in the landfill and lasts for 30 years. The landfill gas utilization conversion efficiency is 70%, with 50% converted to electricity and 50% to heat. The leachate collected during the initial 100 years is collected and treated before being discharged.
