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.

Processing waste materials to recover valuable metals, such as copper, from the materials. The disclosed systems and methods employ processes that further refine the waste materials to concentrate the metallic material after the waste materials are initially processed. Processes include employing air separation and screening. Processes also include employing a dynamic sensor and a vacuum pressure separator to separate metals from other materials. A central processing facility may process metal concentrate from multiple concentration facilities.

The application describes methods and apparatus for recovering materials from waste carpet and of the like products. The carpet material is initially shredded into coarse pieces. These are optionally dried and then subjected to cooling to embrittle at least one components, such as a polymer backing material, while leaving other component e.g. tuff fibres, flexible. In the cooled condition, the pieces are subjected to mechanical action such as hammering or rolling to break up the embrittled material, and these fragments are separated from the other material and recovered. Preferably a drying stage is applied after the mechanical fragmentation, before separation. The procedure may be repeated, optionally with different temperatures to selectively embrittle and fragment different components and facilitate their separation.

The invention relates to a method for selectively separating synthetic organic materials such as polymers and/or reinforced or non-reinforced copolymers in the form of wastes, in particular domestic wastes recyclable in order to be reused. Said synthetic organic materials are recuperated from broken used cars and obsolete consumer durable products. The inventive method for selective separation consists in separating materials which have an identical density threshold value and are selected from a dense medium comprising separate liquid fluid suspensions which consist of powdery disperses particles in an aqueous phase and are stabilised with respect to the density threshold value selected in such a way that a selective separation of a determined fraction of the mixture of separable used material is initiated.

The present invention relates to processes and apparatus for improving municipal waste treatment in autoclave processes. Improvements relate to the use of air-waste stream treatment, indirect heating with thermal fluid, forced steam transfer, autoclave design, waste treatment of contaminated air,classifiers for better separation offibres from glass or gritand processing. The improvements allow more efficient, saferand environmentally friendly processing, and better end products.
摘要:
The invention relates to a method and a device for drying and for the material flow-specific processing of coarse-grained waste that can be aerated. The invention is characterized by subjecting the waste in a first step to a hot air drying step (1) in a tunnel drier (10), followed by the subsequent process steps of sieving (2) to remove the fines, preferably with a grain size
