Decomposition of bio-degradable plastic spoons
Bio-degradable spoons lose some of their weight as quickly as within 30 days after being kept in soil
Bio-degradable plastic materials are able to degrade and decompose over time under natural environmental conditions. The degradation of these bio-degradable plastics is achieved by allowing micro-organisms to metabolize on their surface and decompose the plastic into smaller parts and less harmful materials.
The decomposing of bio-degradable plastic can be done by natural composting or in a landfill. Moisture and oxygen are normally required for the decomposition process to take place and these conditions are readily available in most composting facilities.
Some of the concerns over the use of bio-degradable plastics are the release of carbon dioxide during the decomposition process. The release of carbon dioxide into the environment contributes to the release of greenhouse gases, which cause global warming. However most bio-degradable plastics are made from natural plant material ? and these plants hav consume and reduce carbon dioxide gas in our atmosphere.
