PROCESS FOR RECOVERY OF COMPONENT MATERIALS FROM COMPOSITE PRODUCTS COMPRISING UNCURED RUBBER AND REINFORCEMENT MATERIAL
The disclosure provides a process for the recovery of component materials from composite products, the process including: a) providing a composite product that comprises a plurality of component materials, the component materials including uncured rubber and reinforcement material selected from fabric and/or metal; b) preparing one or more standardised sheets of composite product, wherein each standardised sheet has a maximum thickness of 125 mm or less; and c) jetting pressurised water onto one or more surface of the standardised sheets, whereby the water is at a pressure of up to 500 bar, thereby stripping the uncured rubber from the reinforcement material and resulting in a mixture of uncured rubber fabric and reinforcement material.
Method And Apparatus For Producing Milled Elastomer
The invention is a method for producing milled elastomer, comprising the steps of directing a liquid jet from at least one nozzle on an elastomeric material moving in an at least partially transversal direction with respect to the discharge direction of the at least one nozzle. In the method according to the invention the liquid jet directed on the elastomeric material has a pressure of 650-1350 bar, and the elastomeric material is moved with respect to the at least one nozzle such that, in a first phase adapted for disintegrating a surface of the elastomeric material, the elastomeric material has a first forward-feed rate of 10 to 20 mm/s at a point of impact of the liquid jet in a direction transverse to the discharge direction, and, in a second phase after disintegrating the surface, the elastomeric material has a second forward-feed rate being decreased with 35-65% compared to the first forward-feed rate. The invention is, furthermore, an apparatus for producing milled elastomer.
Method and Device for Separating Multilayer Composite Materials
The invention relates to a method and a device for separating multilayer composite material in which valuable material is located between two layers of the multilayer composite material, in particular in the form of photovoltaic modules (PV), TFT, OLED, or LCD displays, consisting of at least one lower hard layer (1) and at least one soft layer (2, 3) located thereon, wherein one or more layers of the multilayer composite material to be separated is cut in layers or as a whole using at least one high-pressure water jet and is then raised and individualized, and one or more nozzles which discharge the high-pressure water jet are rotated by means of a rotatable nozzle head (DK) about a rotational axis (L) of the nozzle head (DK) while at the same time the nozzle head (DK) and the multilayer composite material are moved relative to each other such that the valuable materials lie freely individually or on the separated layers after the separation process. The device has at least one nozzle (D1, D2) for discharging at least one respective high-pressure water jet, and at least one nozzle head (DK) has a nozzle (DK) arranged outside of the rotational axis of the nozzle head (DK).
Mobile on-site recycling system for a wind turbine blade
A recycling ship configured to sail to an offshore site for recycling a composite material rich structure at the site. The composite material rich structure can include a wind turbine blade, a boat or a ship comprising fiber reinforced composite material. The recycling ship comprises a first processing unit having a cutter configured to receive the composite material rich structure and to section it into composite parts, and a second processing unit having a crusher and/or grinder configured to reduce the size of the composite parts into composite material granulates.
