As a pioneer in the recycling industry, Krall Kunststoff-Recycling can now prove that the CO2 equivalents of the PMMA, PET and PC regrinds produced there from post-industrial plastic waste are up to 95% lower than those of corresponding virgin materials. One key to this particularly high contribution to sustainability is the extensive use of solar energy generated in-house. The calculation of the carbon footprints, which was carried out at a renowned institute, was based on the international standards DIN EN ISO 14040 / 14044 on "Life Cycle Assessment" and DIN EN ISO 14067 on "Carbon Footprint of Products".
