Challenges Facing Municipal Waste Shredding
Lack of technical adaptability is a primary challenge. Existing shredding equipment is mostly designed for specific materials. Hard impurities in mixed waste, such as building debris and metal parts, can easily cause tool wear and even equipment damage. Hard organic matter like bones and shells in kitchen waste can increase shredding energy consumption by 40%, while flexible materials like plastic bags can easily entangle the spindle, reducing efficiency. Further complicating matters, my country’s waste sorting system is still incomplete, and pre-treatment costs for unsorted mixed waste account for over 35% of total processing costs.
The risk of secondary pollution is a constant threat. Fine particles (PM2.5-10) generated during the shredding process can easily escape dust collection systems. Experimental data shows that bacteria levels in untreated shredding exhaust can reach 100,000 times that of ambient air. Dioxin precursors released by mechanical forces from chlorinated plastics can directly generate toxic substances through high-temperature friction. A pilot project in Shanghai experienced a blockage in the leachate collection pipe, resulting in ground pollutant levels exceeding the permitted level by 87 times.
Addressing these challenges requires building a technological innovation system: developing self-cleaning, anti-entanglement cutter assemblies, integrating a linked system for X-ray sorting and mechanical shredding, and developing load-adaptive control technology based on the Internet of Things. Furthermore, exploring a collaborative “shredding + biological treatment” disposal model to reduce the risk of secondary pollution while improving resource conversion efficiency. Only through the coordinated advancement of technological breakthroughs and institutional innovation can the environmental value of waste shredding technology be truly realized.
We are a manufacturer of solid waste disposal machines, including Municipal Waste Shredding machine, double-shaft shredders, single-shaft shredders, sorting machines, metal crushers, and RDF machines.
