Chemicals firms reap bioplastics harvest |
|
The Bioplastics in Packaging event at this year’s Interpack occupied
three times as much space as in 2005, underlining the increased
interest in non oil-based polymers as packaging materials. However,
concerns about source, sufficient supply and subsequent disposal (see
below) have restricted commercial growth.
Last year,
for example, Treofan stopped producing its Biophan polylactic acid
(PLA) due to insufficient predicted sales growth to justify necessary
investment in a new production line. Stanelco said shortage of supply
of material was hindering product development and Innocent Drinks moved
its bottles from PLA to recycled PET, citing the UK’s inadequate
recycling infrastructure.
