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. Not suitable to represent any single specific waste, such as plastics, paper, cardboard. The characteristics of municipal solid waste in Zibo City, Shandong Province are as follows: food waste 46.04%, paper 15.3%, rubber 19.62%, textile (fiber) 4.81%, wood and bamboo 4.75%, ash and soil 5.31%, bricks, tiles, and ceramics 0%, glass 3.48%, metals 0.69%, others 0%. Moisture content 57%. 98%, Higher Heating Value (HHV) 7587.04 kJ/kg, Lower Heating Value (LHV) 5679.24 kJ/kg. The carbon fraction of the initial waste, i.e., 60.4% biogenic. The proportion of unoxidized and recoverable metals in the waste (excluding very small or very thin parts): Iron: 60.03%; Aluminum: 17.81%; Copper: 72.83%. Overall degradation rate of waste over 100 years: 18.73%. Degradability of the waste fraction: Paper: 27%; Mixed Cardboard: 32%. 4% plastic: 1%; laminated materials: 18%; laminated packaging, such as drink cartons: 18%; composite goods, like 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 generates 1.85E-04 kWh of electricity and 6.68E-01 MJ of useful heat.

Process Description

'Municipal solid waste' primarily originates from a wide range of activities across many different sectors. 'Municipal solid waste' consists of the following fractions: food waste, paper, rubber, textiles (fibers), bamboo and wood, ash and soil, bricks and ceramics, glass, metals, and potentially other fractions. These by-products (recyclable or waste) are produced by common transformation activities, thus it's plausible to model the waste output for similar components. In the HiQ database, the handling methods for these by-products include: deposition - sanitary landfill, municipal incineration. Additionally, these by-products are also utilized in the following processes: clinker production.

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.
