Oxo-biodegradable plastic was evaluated by Intertek and confirmed to provide the best LCA of all materials used for making carrier bags and bread bags.
The LCA concluded that the best way to reduce the impact of plastic carrier bags is to re-use them more often, minimise transportation and energy input needed for recycling and make them from oxo-biodegradable plastic.
Bio-based plastic cannot be recycled with conventional plastic as part of a mixed post-consumer waste steam without compromising the recycling process.
The bio-based bag had the worst performance in 10 of the 11 environmental impact categories.
