Degradable rubbish bags

Product analysis: Tuffy d2w™ rubbish bags

The market
Anyone who disposes of waste in plastic bin-liners and refuse sacks - especially domestic households, local authorities and businesses. The bags are sold as high-performance products that do no split or tear, as well as being environmentally acceptable. Some local authorities are now distributing the bags to householders for collecting garden waste that can be used in composts.

Technical specification
This depends on the bag. For example:

Product function
The d2w™ rubbish bags, sacks and bin-liners are totally degradable and strong. They can be used to dispose of all forms of household and garden refuse.

Materials
Polythene combined with an additive that makes the material degradable.

Production
The polythene is formed into a thin, tubular film using standard extrusion methods. It is printed at the same time. This film is then sealed into bag lengths and perforated using a stamping process, so that the bags can be torn off easily.

Safety
All plastic bags are potentially dangerous to small children. However, compared with other polythene bags, which are either non-degradable or partially degradable and which actually prevent decomposition, the d2w™ bags are much more acceptable environmentally. As they degrade, they don't litter the countryside, harm animals or marine life, produce harmful substances or fill up landfill unnecessarily.

Ergonomics
The bags come in a variety of sizes and are easy to use.
