MUNICIPAL SOLID WASTE (MSW) Treatment Plants
W2E- BASIC MODEL
Treatment plant that combines a mechanical pre-separation plant of the different morphological fractions of the waste, a biogas plant and a composting plant. Once separated, the solid fraction is used in co-feeding with other organic waste, mainly liquid, as a feeding diet for a biogas plant, with cogeneration engines for the production of thermal and electrical energy, generating organic composting as a result of digestion process. The other elements of the municipal solid waste, once separated, are sold for recycling. Those that, due to their morphological characteristics, cannot be recycled, such as so-called inert materials: stones, earth, glass, wood, fabrics, are destined for landfill. They represent a reduced percentage of the total treated waste, which significantly reduces the dependence and use of the landfill as a management solution.
Treatment plant that combines a waste sanitation plant with a biogas plant and a composting plant. The sanitization is carried out by means of the autoclave system with the addition of high temperature steam, with subsequent mechanical separation of the different morphological fractions of the MSW, except for the organic one that is already separated at the end of the Sanitization process.
Sanitization consists in subjecting the waste to a treatment with steam at a given operating pressure, and a series of internal movements. This sterilizes the waste, which leaves the sanitation facility free of pathogens, and in formats that make it very easy to separate.
The rest of the process is similar to the one described in the W2E-BASIC model.
Both models can incorporate additional technologies, if required.
