摘要:
- The invention relates to an installation and a method for treating a mixture of waste (4) comprising biodegradable waste, the method being characterized in that it comprises the following successive steps: - Step A: the mixture of waste (4) is subjected to a first composting cycle so as to obtain a mixture of pre-composted waste (4), - Step B: the mixture of pre-composted waste (4) is dried in order to obtain a mixture of dried waste (4), - Step C: the mixture of dried waste (4) is separated into at least one portion of heavy waste (14) and one portion of light waste (13), - Step D: the portion of light waste (13) is subjected to a second composting cycle so as to obtain a mixture of refined waste (4; 20). - Treatment of biodegradable waste.
摘要:
The method and systems efficiently extract recyclable materials from a mixed solid waste stream. The methods and systems use sizing, density and dimensional separation to produce intermediate waste streams that are enriched in particular recyclable materials. The recyclable materials can then be efficiently sorted from the individual intermediate streams using mechanized sorting equipment.
摘要:
A method for solid waste separation and processing (10) comprising the method steps of: (a) Passing a municipal solid waste (12) to a first size based separation step (14) producing at least a fine organic fraction(16) and a coarse fraction (18); (b) Passing the fine organic fraction (16) to a digestion process (20) by way of a glass and grit separation step (24); and (c) Recirculating the coarse fraction (18) of step (a) through the first size based separation step (14) at least once.
摘要:
The installation (10) has a device (12) for fermenting the waste, a device (14) for pre-shredding at least a part of the waste, and a conveying circuit (18) having a section (26) connecting the outlet from the pre-shredding device (14) to the inlet to the fermentation device (12).
