| 'Sustainable' bio-plastic can damage the environment |
|
The worldwide effort by supermarkets and industry to replace conventional oil-based plastic with eco-friendly "bioplastics" made from plants is causing environmental problems and consumer confusion, according to a Guardian study. The substitutes can increase emissions of greenhouse gases on landfill sites, some need high temperatures to decompose and others cannot be recycled in Britain. Many of the bioplastics are also contributing to the global food crisis by taking over large areas of land previously used to grow crops for human consumption. The market for bioplastics, which are made from maize, sugarcane, wheat and other crops, is growing by 20-30% a year. Bookmark this page!      |
