Profile: Blend Colours Private Ltd specializes in providing biodegradable additives and compounds for the Plastic industry. Oxo-biodegradable plastic is made by blending a pro-degradant additive into the plastic during the extrusion process. The additive causes the molecular structure of plastic to break down when exposed to heat or sunlight. Oxo-biodegradable plastic is often referred to as ?degradable? plastic since it does not require a biological process to degrade. Microorganisms will speed up the degradation process, but they?re not required. This gives oxo-biodegradation a distinct advantage over prior methods for degrading plastic.
