Now, environmental protection is only relative, that is, in PP or PE added starch, discarded starch degradation, but PP and PE still, but not as before, all plastic are not degraded only. Fully biodegradable environmentally friendly plastics have not been produced on a large scale, such as carbon dioxide or polylactic acid.
