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 for representing any single specific waste type, such as plastic, paper, or cardboard. The composition of municipal solid waste in Fujian are as follows: kitchen waste 44.76%, paper 13.96%, rubber 25.87%, textiles (fibers) 6.57%, wood and bamboo 3.29%, ash and soil 0%, bricks, tiles, and ceramics 1.44%, glass 1.36%, metals 1.39%, other 1.37%. Moisture content is 56.51%, and higher heating value is 8627. 63 kJ/kg, lower heating value 6667.68 kJ/kg.
For municipal solid waste incineration, each kg of this waste generates 0.205 kg of slag and 0.05 kg of fly ash is landfilled after precious metal recovery from fly ash and slag; the fly ash is solidified with cement at a ratio of 1:1. The average thermal efficiency for waste heat electricity generation is assumed to be 22%; in the waste heat utilization for heating, no conversion between different forms of heat and energy is considered, and the thermal efficiency is relatively high, taken as an average of 64%. By integrating the thermal efficiencies of both waste heat electricity generation and direct heating processes, 15% of the heat generated from waste incineration is used for electricity generation, and 56% is used for direct heating.
It is assumed that municipal-level data within the region are aggregated 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.
