    Leather Belts

    Leather Belts are bioderadable, whereas silver foil, iron nail, plastics are non-biodegradable. Leather biodegrades slowly; it takes 25 to 40 years to decompose. However, vinyl and petro-chemical derived materials will take 500 or more years to break down and return to the Earth.
