Descripción del proyecto
Un método de reciclaje de plásticos para residuos de aparatos eléctricos y electrónicos
Todos los años se exportan de Europa a Asia millones de toneladas de plásticos mixtos generados por residuos de aparatos eléctricos y electrónicos (RAEE), a fin de reciclarlos como plásticos secundarios que contienen sustancias nocivas o para acabar en vertederos. El motivo es que los plásticos de los RAEE contienen aditivos peligrosos que impiden su reciclaje en Europa. Por lo tanto, es imprescindible disponer de soluciones nuevas y eficaces para el reciclado de los RAEE. El proyecto PLAST2bCLEANED, financiado con fondos europeos, tiene el objetivo de desarrollar un sistema de reciclaje de plásticos de los RAEE que sea práctico, económicamente viable y que reduzca el impacto medioambiental. Este método se centrará en el reciclaje de los polímeros más comunes, los pirorretardantes bromados y el trióxido de antimonio mediante tecnologías innovadoras que permitan separar los aditivos peligrosos de los plásticos.
Objetivo
1.2 Million tons of mixed plastics arise from Waste Electrical and Electronic Equipment (WEEE) treatment in Europe and this quantity is still growing. WEEE plastics often contain undesired additives that hamper recycling in Europe. 75% of WEEE is currently exported to Asia where it is recycled to secondary plastics containing undesired (hazardous) substances or ending up in landfill where leaching occurs. Hence for WEEE plastics a closed loop solution is needed.
PLAST2bCLEANED’s aim is to develop a recycling process for WEEE plastics in a technically feasible, environmentally sound and economically viable manner. To fulfil this aim, PLAST2bCLEANED addresses the recycling of the most common WEEE plastics acrylonitrile butadiene styrene (ABS) and high impact polystyrene (HIPS) that contain up to 20wt% brominated flame retardants (BFR) and up to 5wt% of the synergist antimony trioxide (ATO). PLAST2bCLEANED will close three loops: (1) polymer, (2) bromine, and (3) ATO.
Key technologies developed within the project are: (1) improved sorting of HIPS and ABS that contain BFR from other polystyrene and ABS fractions; (2) dissolution of WEEE plastics in superheated solvents; (3) separation of additives to concentrate BFR and ATO fractions for recycling; (4) energy efficient recovery of solvent and of polymer. The developed technology will be integrated in a pilot facility with capacity of 2 kg/hr (TRL 5/6) delivering polymer samples. The developed technology can be applied to similar waste streams from other sectors, e.g. automotive.
The combination of improved sorting and use of superheated solvents offers an economic and environmental advantage. First calculations indicate a sound business case. The consortium is well equipped to develop this technology and consist of partners to cover the whole value chain.
