Materials that decompose through natural processes are called biodegradable whereas those which do not decompose are non biodegradable.
Leather belts are biodegradable whereas silver foils, plastic mugs, and iron nails are non-biodegradable. It takes leather between 25 and 50 years to completely decompose. Leather that has been tanned can take significantly longer to decompose because of the chemicals used to tan it.
