Abstract
A method of recycling/upcycling needle punched PET panels or baffles makes use of a plurality of injection moulded PET components capable of being attached to a needle punched PET panel by plastic welding and to be removably attachable to complementary components fixed or fixable to a support. Spin welding allows the injection moulded PET components to be installed on site or in the factory. The PET panel with its now welded PET components can be press fitted to the complementary components fixed on the wall. A modified form of PET fixing component allows for a suspended baffle or panel. The PET panel or baffle with its PET components welded thereto can be recycled/upcycled without needing to remove the PET components from the panel as they are uncontaminated by any adhesive.
Claims17
A method of fixing a needle punched PET product to a support so that the PET product can subsequently be recycled, the PET product having a front face and a rear face, comprising:
- attaching at least one first PET fixing component to the rear face of the PET product by plastic welding without use of glue, wherein the least one first PET fixing component has a spike protruding from one face which is pressed into the needle punched PET product to locate the least one first PET fixing component,
- attaching at least one second complementary mechanical fixing component to a support,
- attaching the PET product to the support by a mechanical connection between the least one first PET fixing component and the least one second complementary mechanical fixing component so that they are releasably attached together by the mechanical connection without use of glue contaminating the needle punched PET product thereby allowing the PET product and the least one first PET fixing component to be recycled.
