nature : organic material through the biological role of people grateful to be decomposition (organic matter mineralization were damaged or for inorganics) phenomenon. Plants, animals right into the body and have a certain degree of organic degradation capacity, but biodegradable microbial degradation of the largest role, also known as microbial degradation (microbiological degradation). Degradation of ease, and decided to microbial itself, but also with organic structure. Simple structure are more likely to degradation, complex structures will be less degradation. Human activities with the needs of living, production and economic development, many organic poison into the soil and water, causing environmental pollution and degradation through microbial life can effect the repeated elements may become so complex to the degradation of organic matter, thus enabling environment purification, to maintain the ecosystem virtuous cycle. Polymers and Composites can be the molecular microbial degradation resistance, for example, left in the soil broken farm PVC films will be very difficult to be biodegradable, causing pollution.
