COMBINED PROCESS FOR TREATMENT AND RECYCLING OF MUNICIPAL SOLID WASTE / MSW/ WITH COMPLEX MORPHOLOGICAL COMPOSITION

摘要

The treatment technologies for municipal solid waste (MSW) are effective mainly for components sized over 40 - 50 mm. This fraction is separated by screening in the beginning of the process. Usually the undersized product is deposited without additional treatment. Its quantity is variable from several up to 30 - 40 % of the total MSW. Both oversized and undersized fractions are formed by all types of primary matter.Adapted technologies from mineral processing will provide a suitable technology for treatment of MSW under 40 - 50 mm. The MSW content depends on the geographical location, the degree of urbanization and other factors. The methods can be applied for separations of different components suitable for recycling or other utilization are:• Separation by density;• Separation in thin liquid layer;• Selective grinding and screening;• Flotation, etc.
