What are environmental bags

Environmental bags are made in such a way that its material can biodegrade which is a process by which organic substances are broken down by the enzymes produced by living organisms.

What environmental bags are made of?

Environmental bags can be made from many different sources and materials such as starch based polymers, polyesters (bacteria based polymers), starch or polyester blends, oxo-biodegradable polymers, photodegradable polymers and water-soluble polymers.

Biodegradable plastic bags

Biodegradable plastic bags quickly degrade when disposed of by the action of bacteria, these include kitchen waste and refuse bags, bin liners, carrier bags and standard bags. Degradable plastic bags instead degrade by the action of chemicals.

What is the difference between degradable and biodegradable?

Degradation is a process whereby very large molecules are broken into smaller molecules or fragments. Normally this process is aerobically, oxygen is incorporated into these molecular fragments. As the molecules of which the films consist become much smaller they become weak and likely to break as a result of oxidative degradation. Degradation can be caused (initiated) by heat, or exposure to UV light and is enhanced by mechanical stress.

Biodegradation is the process by which microorganisms such as bacteria, fungi or algae, convert materials into biomass, carbon dioxide and water.

There are two main differences between 'degradable' and 'biodegradable'. Firstly, heat, moisture and/or UV exposure most often causes the degradation of a degradable product, whereas microorganisms degrade a biodegradable product. Secondly, degradable products tend to take much longer to break down into carbon dioxide, biomass and water.

When degradable plastics break down into smaller molecules, eventually they will be small enough to be consumed by microorganisms and so biodegradation occurs. In essence then, all degradable films will eventually biodegrade but at different speeds.

Biodegradable or Biodegradeable?

Two words commonly misspelt: biodegradable and degradable as biodegradeable and degradeable(please take note yourself as some of our domains are actually misspelt!) .When written down these words often look like an incorrect spelling and have been known to be corrected to biodegradeable by some overzealous and missinformed editors.
