Biodegradable packaging from plant material

Many people unfortunately leave behind dishes, plastic bags and disposable cutlery after a picnic in the countryside. In the case of biodegradable material we do not have to worry about the future of such debris. After the materials made of bio plastics are left on the ground in just a few weeks they degrade naturally. Also in landfills bio plastics decompose turning into industrial mould which eliminates the problem of disposal and recycling.

Biopolymers are the products of a fusion based on sugar, starch, cellulose, lignin, and vegetable oils. According to calculations, the life cycle of biopolymers (from receipt to complete digestion in a landfill or burned as fuel) produces much less carbon dioxide than plastics from petrochemical feedstock.

Manufacture of polymers based on vegetable raw materials is the way of energy conservation. For example, compared with polyethylene for each ton of bio plastics there is a saving of 12 to 40 GJ of energy. In addition, biodegradable plastics from natural ingredients alleviate the problems of disposal, composting and waste plastic including packaging materials.

Advantages of biodegradable polymers:

- ability to process, as conventional polymers, using standard equipment.

- low barrier passing oxygen and water vapour (optimised for use in food packaging).

- rapid and completely degradable in natural conditions.

- no problems with the disposal of waste.

- independence from petrochemical raw materials.

- biodegradable from plant materials are recyclable without damaging the environment.
