Willow Ridge Plastics, Inc. is the leading manufacturer of oxo-biodegradable additives, with over 24 years of experience. As pioneers of the industry, we are in the forefront of developing technological breakthroughs that set new ecological and quality standards. WRP is the only ISO 9001:2008 accredited manufacture of oxo-biodegradable additives. Using the highest state of the art equipment, our in-house testing laboratory, analyze and validates oxo-biodegradable performance. All testing is based on current ASTM standards.
WRP oxo-biologically degrades almost all plastic products that are disposed in the landfill. WRP makes plastic "rust" by using the oxo-biodegradation process, time, ambient heat, and/or UV light, WRP's additives will completely oxidize the plastic. Oxidation reduces the molecular weight of the plastic and allows for oxygen containing functional groups to form within the polymer. This allows microorganisms to further biodegrade the polymer once it has been disposed of in the landfill.
