Biopolymers are polymers produced by living organisms, cellulose, starch and chitin, proteins and peptides. DNA and RNA are examples of biopolymers, in which the monomeric units respectively, are sugars, amino acids and nucleotides. Biopolymer bags are created using natural renewable resources such as starch and cane sugars.


Composting is the transformation of organic waste into compost. A pile of organic waste attracts micro organisms normally present in the environment. If the water content is sufficiently high, the micro organisms start to consume the nutritional substances. This degrades the organic molecules, produces carbon dioxide, water and heat (biodegradation). At the end of the process, the initial waste is transformed into a substance called compost. In commercial composting plants, this process is controlled and optimized in order to achieve high conversion rates, control the effluent and control the quality of the final compost.


Biodegradability is the fragmentation and degradation of product by natural means. The breakdown is caused by micro organisms and bacteria present in the soil, as for example the biodegradation of fruit or vegetables. The product, plant or fruit is decomposed, leaving no harmful traces as it returns to the soil.

Degradability on the other hand, is the fragmentation of product or bags, not caused by micro organisms and bacteria. There are products around such as ox-degradable bags and others that are treated with chemicals that in some circumstances cause fragmentation. There are fragments and residues left which are harmful to the soil and these residues can return to our food chain, i.e. plankton, causing further harm to our environment.
