New bioplastics are being made in laboratories from straw,wood chips and food waste,
with researchers aiming to replace oil as the source of the world's plastic
The new approaches include genetically modifying bacteria to eat wood and produce
useful chemicals.But the bioplastics are currently significantly more expensive to make
than fossil fuel-based plastics.
Land and seas around the world,from high mountains to deep oceans,have become
polluted with plastic,prompting major public concern.The world has produced about 8
billion tonnes of plastic since the 1950s and demand is still rising.
While some waste plastic is recycled,much of it is burnt to produce electricity,
resulting in carbon emissions that drive climate change.In contrast to plastic made
from oil,plastics made from plant-based materials only release the carbon the plants
absorb from the air as they grow.Bioplastics will also give more options for products
that biodegrade in the environment,although they can be made very long-lasting if
required.
"Plastics are an incredible enhancement to our daily lives,"said Paul Mines,CEO of
Biome Technologies in the UK,which has spent f 5m in the last five years on
bioplastics research."But we can't go on using fossil fuel-based materials.About
6%-7%of every barrel of oil is used to make plastics."
Using plant materials is feasible,said Professor Simon,at the University of
York.Replacing half of the nation's plastic bottles could be done by using just 3%of
the sugar beet crop,5%of wheat straw or 2.5%of food waste,he said.
Currently,just a few thousand tonnes of bioplastics are used in the UK each year,
compared to millions of tonnes of conventional plastic.Mines said this could rise to
about 20,000 tonnes in the next five years.
