I. What is Urban Solid Waste?
Urban solid waste (MSW), commonly referred to as municipal waste, refers to solid or semi-solid materials generated and discarded in daily urban life. It mainly includes:
1. Household waste: Kitchen waste, packaging materials, and discarded items generated by households.
2. Commercial waste: Waste generated by shopping malls, offices, restaurants, etc.
3. Public place waste: Waste collected from public areas such as parks, streets, and stations.
4. Some construction waste: Construction waste generated from small-scale renovations and repairs (large-scale construction waste is usually classified separately).
II. Modern Challenges of Urban Solid Waste Management
Currently, urban solid waste management faces multiple challenges: continuously increasing waste production, insufficient awareness of waste sorting, shortage of treatment facilities, low resource recycling rates, outdated treatment technologies, and difficulties in facility site selection due to the “not in my backyard” (NIMBY) effect.
III. High-Efficiency Sorting and Processing
As a professional manufacturer of waste sorting equipment, we offer the following urban solid waste management solutions:
1. Automated Sorting Systems
– Mechanical Screening Equipment（trommel screen): Separates different components by size
– Magnetic Separator: Highly extracts metallic substances
– Eddy Current Separator: Separates non-ferrous metals
– Air separator: Separates Materials by Weight.
– Optical Separation Equipment: Identifies plastic and paper types using near-infrared and visible light technologies
– Artificial Intelligence Sorting Robots: Achieves high-precision sorting through machine vision and deep learning
2. Biological Treatment Technologies
– Anaerobic Digestion: Processes organic waste to produce biogas energy
– Aerobic Composting: Converts organic matter into high-quality fertilizer
3. Energy Recovery Systems
– Waste Incineration Power Generation: Converts non-recyclable waste into energy
– Pyrolysis Gasification Technology: A cleaner energy recovery method
4. Secure Landfill
– Sanitary landfilling of residues that are non-recyclable and unsuitable for incineration
– Equipped with a complete anti-seepage, leachate collection and treatment, and biogas collection system
IV. Resource Utilization and Circular Economy
1. Material Recycling: Recycling of plastics, glass, metals, and paper
2. Organic Matter Recovery: Compost products used for urban greening and agricultural production
3. Energy Recovery: Waste-to-energy incineration integrated into the city power grid
4. Industrial Synergy: Establishing a resource recycling industrial chain to form a closed-loop economy
V. Cases of Urban Solid Waste Management
Taking our company’s integrated solid waste treatment system designed for a coastal city as an example:
– By deploying intelligent sorting lines, the resource recovery rate increased from 25% to 65%.
– Artificial intelligence sorting robots improved the purity of plastic sorting to 98%.
– The organic waste treatment system generates 30,000 cubic meters of biogas daily, supplying electricity to 5,000 households.
– Overall landfill volume was reduced by 70%, extending the landfill’s lifespan by more than 15 years.
