CO-PROCESSING AS VIABLE RECYCLING ROUTE FOR GLASS FILLED COMPOSITES
OEMs and designers need to have peace-of-mind on the availability of reliable end-of-life solutions for the composite parts and components they create. The recycling of composite regrind through co-processing into cement proves to be such a reliable solution, bringing substantial benefits in minimizing carbon footprint. Aliancys is introducing its newest brochure, providing customers with insight into this recycling route and its positive impact on the environment.
Co-processing is the simultaneous use of composite regrind as raw material and as a source of energy in cement manufacturing, replacing natural mineral resources (material recycling) and fossil fuels such as coal, petroleum and gas (energy recovery). The co-processing process has been recognized by the EU Commission as recycling route for composites.
Already in 2012 Aliancys worked with cement manufacturer Holcim/ Geocycle to better quantify the ecological benefits of using composite regrind for making cement. For this purpose, the companies used a detailed LCA model developed in close collaboration with the Swiss Federal Institute of Technology (ETH) in Zürch, Switzerland.
Glass filled composite regrind can be used up to levels of 75 % of raw material weight in the process. Interestingly, it was calculated that at those levels the addition of composites allows reducing the CO2 emissions of the cement clinker production with 16 %. This is obviously a major reduction for a process that inherently generates fair amounts of CO2 because of the chemistry involved. Additional detail on study and results can be found in the new Aliancys brochure. Please click here to download a copy.
