As bacteria discover the plastic is not a viable food source, they then begin feeding on each other. Bacteria in these vats isn’t able to convert the carbon in plastics into CO2 very efficiently, but as the bacteria in an area attempts to feed they produce an electrical charge that attracts other bacteria in the vat. In multiple test vats containing 3d printed parts made from pure PETG, measurable CO2 production is primarily a result of the bacteria cannibalizing each other. In independent tests 3d printed parts made with BioPETG provide a constant food source for the bacteria in each test vat, and measurements showed steady production of CO2 during the entire 45 day test period. (Average results of combined tests) BioPETG: ASTM D5511 measures anerobic biodegradation. Our bio-additive simply provides a food source for bacteria living in active landfill facilities and commercial composts, but 3d printed parts maintain the strength, pliability, heat resistance, chemical resistance, and post processing capabilities of PETG in every way, delivering a more sustainable 3d printing experience.īioPETG meets both ASTM D5338 and ASTM D5511 standards for biodegradability.ĪSTM D5338 determines the degree and rate of aerobic biodegradation of plastic materials by measuring a percentage of conversion of carbon in the sample to carbon dioxide. BioPETG is a professional grade PETG combined with our proprietary bio-additive technology that delivers a sustainable PETG filament, without compromising material performance.
