"Three islands and two networks" model of comprehensive solution for waste free city construction

Wanrong adheres to the concept of "turning garbage into resources", constructs the urban-rural waste recycling and "three islands and two" industrial model with three nuclear technologies, and contributes to the great process of "carbon neutralization".

• Urban and rural waste resource utilization ecological industrial chain
• Classified collection and transportation reverse logistics network and big data information internet
• Recycling of urban recyclables (blue island)
• Rural waste collaborative disposal (Green Island)
• Distributed RDF and intensive energy conversion (energy island)

Comprehensive solution for rural environmental governance ecological island model

With the concept of natural ecology and the method of system engineering, wanrongzhi has built an ecological factory for waste recycling - "ecological island" by means of resource utilization. "Ecological island" includes domestic waste and organic waste MBT treatment system, waste classification and renewable resource recovery system.

Dismantling and resource utilization of household appliances and end-of-life vehicles

The technology and equipment for harmless treatment and resource recovery of Waste Refrigerators independently developed by the company has a unique patent combination design of "double shaft shredder + vertical crusher + large air volume dilution cyclopentane gas". It is mainly used for the separation, recovery and utilization of various raw materials in waste refrigerators. It has independent intellectual property rights, The scientific and technological achievements of the Ministry of industry and information technology were identified as "filling the domestic gap and reaching the international advanced level".

Physical and chemical recovery and disposal of waste tires and plastics

Adopt anaerobic pyrolysis technology to realize the physical and chemical recovery of waste tires and plastics, and solve the "white pollution" and "black pollution" that perplex the world. Provide crushing and sorting equipment, front-end pretreatment and terminal pyrolysis, and whole plant system services for comprehensive utilization of waste tires. On the premise of safe, environmental protection, continuous and stable operation, waste tires (waste rubber products) are finally transformed into steel wire, pyrolysis oil and pyrolysis carbon to realize resource-based, harmless and reduction disposal. Packaging waste plastics, sorted municipal waste, industrial waste plastics, agricultural film, paper mill waste, etc. can no longer be used directly. After crushing, sorting and anaerobic pyrolysis, they are finally transformed into high calorific value energy products, pyrolysis oil and pyrolysis carbon, so as to realize resource-based, harmless and reduction disposal.

Pyrolysis treatment of hazardous packaging and medical waste

Provide pyrolysis resource utilization system services for waste packaging containers / materials and medical wastes. Hazardous waste packaging containers finally form iron, pyrolytic oil and pyrolytic carbon through "decapping and flattening + pyrolysis + crushing and screening" and "crushing + pyrolysis + screening", so as to achieve the effect of resource utilization of hazardous waste packaging. The medical waste is poured into the feed bin by the movable Tipper and then fed into the pyrolysis and carbonization treatment by the double roller feeder. The product pyrolysis oil and pyrolysis carbon can be sold as fuel.

Pyrolysis treatment of municipal sludge, industrial sludge and oil sludge

It is applicable to municipal sludge produced by urban sewage treatment plants, underground pipe networks and river channels, and industrial sludge produced by paper making, printing and dyeing, leather industry and down manufacturing industry; Oily contaminated waste, ground sludge, refinery sludge, tank bottom sludge, drilling cuttings, ground oil spill and other oily sludge (hw08). After pretreatment, sludge and oil sludge are finally transformed into main products such as pyrolysis oil and pyrolysis carbon through anaerobic pyrolysis technology and equipment on the premise of safe, environmental protection and stable operation, so as to realize their reduction, harmless treatment and resource utilization.
