A waste treatment dilemma triggered by "resource mismatch" is spreading nationwide. On the one hand, cities face a "raw material shortage": Some newly built large-scale waste incineration plants suffer from excess capacity and the dilemma of "not getting enough to process," forcing them to transport waste from counties and rural areas across regions. On the other hand, there is a "disposal crisis" for waste in towns and townships: In remote counties, towns, and rural areas, with the closure of landfills, large amounts of waste are left "nowhere to be disposed of."
Recently, a "Municipal Solid Waste Molecular Membrane Fermentation Chamber Resource Utilization Technology and Complete Equipment" that passed scientific and technological achievement evaluation has provided a new path to solve this dilemma. Independently developed by Vary Tech, this technology is becoming the key to breaking the urban-rural waste treatment contradiction.
The technology takes the high-efficiency molecular membrane fermentation chamber as the core unit, integrating a technology chain of pretreatment, rapid composting, and screening. It biologically decomposes and composts the organic matter in waste, simultaneously achieving high-efficiency deodorization and drying. Finally, organic waste is converted into nutrient soil or organic fertilizer, directly used for landscaping and soil improvement. For the sorted plastic packaging and other high-calorific components, they are made into stable-form, standard-calorific-value Refuse-Derived Fuel (RDF), accounting for about 35% of the total treatment volume.
Breakthrough 1: Alleviating the 'Hunger' of Incineration
As a standardized fuel product for transportation, RDF is easy to store and transport over long distances, significantly reducing the transportation cost per unit calorific value by more than 85%. This enables RDF to be economically and efficiently delivered to incineration power plants or cement kilns hundreds of kilometers away that are "starving for materials," serving as high-quality alternative fuel and effectively filling the raw material gap of large-scale waste incineration plants.
Breakthrough 2: Perishable Waste in Counties Also Finds a Solution
The molecular membrane fermentation chamber technology is adapted to small-scale application scenarios, providing a fundamental solution to the waste dilemma in towns and townships: By building local ecological treatment centers – "Green Islands," it realizes one-stop collaborative disposal of county-level waste, efficiently processing various organic wastes such as domestic waste, food waste, municipal sludge, livestock and poultry manure, and rural straw.
The organic components in county waste (such as food waste, straw, sludge, fruit and vegetable waste, livestock and poultry manure, etc.) are efficiently converted into nutrient soil or organic fertilizer in the station, directly used for local soil improvement or landscaping to achieve local resource recycling. The sorted high-calorific components (such as plastics) and domestic waste are made into standardized RDF fuel, which is transported to energy enterprises.
At present, Vary Tech's molecular membrane fermentation chamber technology has been industrially applied in domestic waste treatment projects in many provinces, including Hunan, Guangdong, Henan, etc.
