Drastic changes await Bioplastics use in packaging industry

NEWYORK (Scrap Monster): Packaging market demand gradually shifts from biodegradable and compostable polymers towards biopackaging based on renewable and sustainable materials, says a report from Pira International.

According to the study titled The Future of Bioplastics for Packaging to 2020: Global Market Forecasts a new breed of bioplastics will become significant drivers.

Pira expects the fast-growing GM and bio-derived segments will account for a quarter of total bioplastic packaging market demand by 2020. Polyhydroxyalkanoates (PHA) are forecast to achieve a CAGR of 41 per cent and bio-derived PE a staggering 83 per cent over the period.

It also foresees the current top five suppliers, which presently meet more than half of global supply, will be joined by a raft of other companies as novels manufacturing streams come on-line.

Global bioplastic packaging demand is forecast to reach 884,000 tonnes by 2020. A 24.9 per cent compound annual growth rate (CAGR) is expected from 2010-15 slowing to 18.3 per cent in the five years to 2020, said the analysts.

From 2010 bioplastic technology is expected to change with the commercialisation of materials produced directly by natural/genetically modified (GM) organisms and the introduction of non-biodegradable, bio-derived polyethylene (PE), said the report

At the same time traditional bioplastic packaging technologies based on starch, cellulose and polyester are each forecast to show a decline in market share.

The report said the current highly concentrated Bioplastics market is also set to see major changes as new firm join the top rank of suppliers.

It forecasts that large petrochemical companies such as Braskem, Dow Chemicals and Solvay are scheduled to commence bio-derived PE production by 2012 at industrial-scale facilities in Brazil.

Telles, the joint venture PHA producer, is also expected to become a major world player and several Chinese companies are known to be investing in significant capacity expansion programmes that should propel them into leading market positions, added the report.

The period is also due to see significant technological advances in fields such as algae and carbon dioxide-based materials. A new sugar-based bioplastic that can be sourced from non-food crops and produced via a low energy process is also tipped to reach the market within the next five years.

Europe is currently the largest market for bioplastic packaging with demand account for more than a 50 per cent share of world tonnage in 2010. While North America and Asia are presently lagging behind, Pira said it expects growth rates in these two regions to outstrip Europe in the period to 2020 – with Japan predicted to continue driving Asian expansion. Rigid packaging presently has a 52 per cent share
