A compostable material is always biodegradable.
Biodegradable refers to the ability of a substance to break down into small enough parts so that microorganisms can consume it. Biodegradable products break down naturally when placed in a land fill, if given enough time. “Bio” meaning “life”, “degrade” meaning to break down, and “able” of course meaning that it can happen.
- Breaks down into smaller sized pieces
- Requires heat, water oxygen and micro organisms but may never fully break down
- May take decades to disappear
- Plastic biodegrade into smaller pieces of plastic over a longer period of time
Compostable refers to the ability of a microbes to break down materials. Products that compost leaves no visible, distinguishable or toxic residue and generally help improve the soil. Composting is the process of recycling organic waste so that it can eventually be reused.
- Breaks down into non-toxic components
- Requires heat, water, oxygen and micro organisms to fully break down
- Breaks down completely and does not harm plant growth
- Bio based materials break down faster as long as the right condition are met
