With a variety of green and environmental products in the market, it is easy to find yourself confused or misled by various terminologies including the definition of biodegradable, compostable and degradable.
Biodegradable
Biodegradable indicates the process of biological breakdown by microorganisms including, bacteria, fungi and enzymes. These microorganisms eat away at the biodegradable material leaving behind only natural constituents of biomass, carbon dioxide and water. Subsequently these natural materials can be safely re-absorbed back into the earth.
Compostable
Compostable refers to the biological breakdown and recycling of ‘Organic’ or ‘Biodegradable’ materials within a composting environment. An ideal composting environment is subject to certain heat or moisture conditions. Decomposition of such materials results in the addition of rich nutrients to the soil and can be an effective form of fertiliser for home gardeners and farmers.
Degradable
Degradable products are oil-based with an additive included to trigger the process of degradation – They are not biodegradable or compostable. Degradable materials break down via a chemical reaction and the end results of degradation do nothing more than break down the oil components into smaller fragments leaving behind the same amount of plastic dust. Degradable bags require specific UV conditions in order to break down and will remain intact when composted or buried in landfill.
