Beer and soft drinks could soon be sipped from “all-plant” bottles under new plans to turn sustainably grown crops into plastic in partnership with major beverage makers.
A biochemicals company in the Netherlands hopes to kickstart investment in a pioneering project that hopes to make plastics from plant sugars rather than fossil fuels.
The plans, devised by renewable chemicals company Avantium, have already won the support of beer-maker Carlsberg, which hopes to sell its pilsner in a cardboard bottle lined with an inner layer of plant plastic.
Avantium’s plant plastic is designed to be resilient enough to contain carbonate drinks. Trials have shown that the plant plastic would decompose in one year using a composter, and a few years longer if left in normal outdoor conditions.
The bio-refinery plans to break down sustainable plant sugars into simple chemical structures that can then be rearranged to form a new plant-based plastic – which could appear on supermarket shelves by 2023.
The path-finder project will initially make a modest 5,000 tons of plastic every year using sugars from corn, wheat or beets. However, Avantium expects its production to grow as demand for renewable plastics climbs.
