Synt3® and Bio-D
Synt3® Srl, always been concerned with environmental matters in every stage of production process, has now the pleasure to present a new range of biodegradables polyurethane articles, called Bio-D.
Bio-D is part of an ecological- oriented vision of future business by Synt3®. Our primary goal is responsible management of natural resources and environmentally safe degradation of our materials at the end of their product life cycle.

Bio-D and Biodegradability
Biodegradability is the property of a material to safely biologically degrade in the environment, (i.e., to be consumed by microorganisms in aerobic or anaerobic conditions) and return to organic compounds found in nature. In particular, Bio-D degrades into carbon dioxide, water (or methane), mineral salts and biomass. According to the strict European standards, EN 13432 and EN 14995, a material can be considered as biodegradable if it degrades by at least 90% within 6 months (180 days). The biodegradability test guarantees that the leftovers (with maximum level of 10%) will be degraded safely into the ground. UNI EN 14046 and ISO 14855-1 standards regulate the execution of ultimate aerobic biodegradation under controlled composting conditions. During these tests of our Bio-D, fine particles of Bio-D material were placed in compost (a mixture of organic materials particularly apt for the developing of microorganisms) and kept at controlled temperature (58°) and humidity (40%), under presence of oxygen. After 180 days, Bio-D resulted to be biodegradable in compost by reaching an average value greater than 90%. This confirms that the Bio-D is biodegradable in accordance with UNI EN 13432-2000.

The below chart shows the biodegradability curve of the Bio-D, as follow: Blue color = Bio-D; Yellow color = Cellulose, used as benchmark reference item because 100% biodegradable.
