Composting Miscellaneous Materials

Many plastics are biodegradable, however, the common plastics are often not. Plastics degrade in UV sunlight and UV degraded plastic is biodegradable. It can take a long time for these to biodegrade, usually varying between 50-500 years depending on the environmental conditions.

Always check whether the time quoted for a material to biograde is based on sea water, landfill (anaerobic), soil (cold composting), hot composting (aerobic), exposed to sun etc.
