Solid waste management is the process of collecting, transporting, processing, recycling, and disposing of solid waste in a way that minimizes its impact on the environment and public health. Solid waste refers to any non-liquid waste generated by households, businesses, industries, and other sources. This can include garbage, food waste, yard waste, construction and demolition debris, and hazardous waste.
Effective solid waste management practices include source reduction, which involves reducing the amount of waste generated at the source, recycling and composting, which diverts waste from landfills and incinerators, and safe disposal of remaining waste in a manner that minimizes the risk to the environment and public health. Solid waste management systems vary by country and region, and can be managed by government agencies, private companies, or a combination of both. The goal of solid waste management is to create a sustainable system that balances the need to dispose of waste with the need to protect the environment and public health.
Solid waste management is typically categorized under the larger category of municipal solid waste management (MSWM). Municipal solid waste refers to the waste generated by households, businesses, and institutions within a municipality or urban area. This includes solid waste such as household garbage, food waste, yard waste, and other non-hazardous waste. MSWM is the management of the solid waste generated within a municipality, which includes collection, transportation, processing, recycling, and disposal of the waste. The management of solid waste can be carried out by government agencies, private companies, or a combination of both, depending on the country and region. The goal of MSWM is to provide safe and effective management of solid waste, while minimizing its impact on the environment and public health.
With the growth of population and industrial and economic development, municipal solid waste (sludge, garbage) production increased dramatically. Municipal solid waste(MSW), known as garbage or rubbish, is a waste type that is discarded by people every day. Generally speaking, there are three sources of municipal solid waste.
◎ Domestic solid waste comes from households and public areas, including waste collected from residential buildings, litter bins, streets, marine areas, and country parks.
◎ Commercial solid waste comes from shops, restaurants, hotels, offices, and markets in private housing estates.
◎ Industrial solid waste is generated by all industries but does not include construction and demolition waste, chemical waste, or other special waste.
The municipal solid waste sorting machine adopts a precise waste sorting system and has a strong capacity of sorting as many as 400 tons of wastes for one production line. Our waste separation machine can separate the various wastes clearly according to their volumes, materials, natures and future usages, etc. It cannot only be used for treating municipal solid waste but also used for mining waste sorting.
Municipal solid waste sorting machine is a large waste sorting facility for wastes centralized processing. Most of the time, it is the first step for wastes treatment. Since many wastes are recyclable, you may need subsequent plants for reprocessing them and then get more profits, such as pyrolysis plant, carbonization machine, plastic pelletizing machine, etc.
Municipal solid waste enters the feeding system by grab or front loader, and then through pre-shredding and bag opening processing, using different screening equipment, such as trommel screens, ballistic screen, star screen and waste vibrating screen, separated waste to different size stream, and then use magnetic separation system, eddy current separation system, air separation system, optical sorting system and AI robot sorting system to get plastics, paper, metals and other recyclable materials.
1. The organic waste is sorted out, it can be used for anaerobic digestion and biogas power generation, and the residue can be used for composting.
2. After the inert waste is sorted out, it can be made into concrete aggregate, cement and building materials.
3. The remaining non-recyclable high-calorific value waste often includes a small amount of mixed plastic film, a small amount of lightweight paper, composite fabrics, etc. After shredding, the size of this mixed waste is less than 50mm, which can be made RDF and SFR for incineration and power generation.
