Autoclave MSW Sorting with Plastic Waste
Innovative and Tech Projects
Our team of engineers spans 10+ years of experience in development and implementation of innovative technologies in petrochemistry. However, as we started to learn about heavy industry we realised, that decarbonisation, waste treatment and emission reduction not only beneficial form ecological point of view, but can also be financially sustainable. So we started to focus on projects for both Russian and international clients in areas such as process and energy audit, process design, equipment design, process scale-up and outsource manufacturing of equipment with the aim to fulfil SDG’s and create a positive ecological and social impact. The project is focused on the secondary use of resources and waste recycling as a combination of two technological processes: autoclave sterilization and plastic waste Remolecularization. Stage 1: Autoclave. Unsorted MSW is gridded transferred into the autoclave, where sterilized with high-pressure steam, which helps to get rid of organic residue and generally cleans it. Then, using various separators, waste is divided into fractions (metals, glass, biomass, aluminium, etc.), which can be sold in an open market. Only 4% to 10% of the neutral processing residue is sent to the landfill, and ideally can also be used as a mineral filler for building materials. The cost of raw materials is a key factor in the process. Since manual sorting of plastic requires huge financial costs, autoclave sorting is used as a more cost-effective technology. Due to the automation of the process, this two-stage technology not only greatly increases the availability of mixed clean polymer waste (the most suitable material for de-polymerization), but also guarantees a certain raw stream from autoclave to industrial plant. Stage 2: Plastic Waste Remolecularization The plastic fraction obtained in the first step is supplied to the plant for recycling a mixture of plastic wastes. The process is based on thermos-catalytic de-polymerization with the production of liquid monomers and subsequent hydration. This makes it possible to produce stable gasoline and kerosene solvents and diesel components, ready for sale to wholesalers and retailers. This approach not only allows to reduce the amount of MSW by 90%, but also fractions, obtained from both stages, can be sold on the open market, which ensures the financial profitability of the business.
