Biodegradable products are made of biodegradable materials that can decompose naturally when exposed to microorganisms (eg. bacteria) in the environment. Some products break down quickly while others take a much longer period of time to completely decompose. Some examples of biodegradable materials are paper, corn starch, vegetable oils, and animal fats.
Some biodegradable products do not completely break down and may leave behind harmful chemicals. Example of such product is Oxo-degradable bags that are made of Oxo-degradable plastics.
Compostable products are products made of compostable material. Composting is the process of breaking down organic waste – such as vegetable scraps, paper, and dead leaves – into a dark, crumbly, nutrient-rich material called compost. Compost is used to enrich the soil in your garden, or wherever you grow your favorite plants. Composting is an important part of reducing the amount of organic trash that ends up in landfill.
Generally speaking, all compostable products are biodegradable. However, not all biodegradable products are compostable.
