Tesco drops oxo biodegradable bags
Friday, August 19, 2011
British supermarket chain Tesco ended the use of oxo biodegradable plastic following research findings saying biodegradable plastic bags could be more harmful to the environment.
Oxo biodegradable bags are made of nonrenewable plastics, which are able to degrade in the presence of oxygen and sunlight thanks to the addition of small amounts of metals.
“We took the decision to remove the biodegradable additive because we believed it contributed towards bags becoming weaker and to help better promote their reuse and recycling at end-of-life,” a spokesman for Tesco said.
The decision was based on research conducted by the Department for Environment, Food and Rural Affairs disproving that plastic bags will degrade to water, carbon dioxide and biomass in 18 months. The report concluded that degradability depends on where and what conditions the bag ended up after use.
Currently, Tesco uses non-biodegradable carriers that contain 15 percent recycled material. – K.D. Mariano
