Description
This dataset represents the treatment of 'municipal solid waste, sanitary landfill'. The recommended use of this dataset is for average municipal/public waste mixtures. It is not suitable to represent any single specific waste type, such as plastics, paper, or cardboard. The composition of municipal solid waste in Qinghai are as follows: kitchen waste 47.78%, paper 6.85%, rubber 9.41%, textiles (fibers) 2.72%, wood and bamboo 1.75%, ashes and soil 0%, bricks, tiles, and ceramics 27.22%, glass 2.89%, metals 1.21%, others 0.17%. Moisture content is 55.81%, and higher heating value is 5367. 35 kJ/kg, lower heating value 3624.71 kJ/kg.
Assume that municipal data within the region are combined with equal weights.
Process Description
"Municipal solid waste" is primarily generated from a wide range of activities across many different sectors. "Municipal solid waste" includes the following components: kitchen waste, paper, rubber, textiles (fibers), wood and bamboo, ashes and soil, bricks, tiles and ceramics, glass, metals, and potentially other fractions. This by-product (recyclable or waste) arises from common transformation activities and can therefore be considered for modeling waste outputs of similar composition. In the HiQ database, treatment methods for this by-product include: landfilling – sanitary landfill, municipal incineration. Additionally, this by-product is used in the following process: clinker production.

Technology comment
This is an inventory for a sanitary (controlled) landfill site for municipal solid waste. The final average landfill height is 20 meters. The operational phase lasts for 30 years. Landfill gas collection and utilization begin one year after waste disposal and continue for 30 years. The landfill gas utilization efficiency is 70%, with 50% converted into electricity and 50% into heat. Leachate collected during the first 100 years is collected and treated prior to discharge.
