Companies that make packaging from plants instead of fossil fuels are starting to challenge the oil industry’s ambition to increase the supply of raw materials for plastics. Use of bioplastics made from sugar cane, wood and corn will grow at least 50 percent in the next five years, according to the European Bioplastics Association in Berlin… Bioplastics … about 1 percent of the plastics market … are made by processing sugars from plants and tend to have a smaller carbon footprint than their conventional counterparts. …“Alternative raw materials must be competitive,” Stora Enso’s Chief Financial Officer Seppo Parvi said … anticipating eventual price parity with crude plastics. “I’m confident we’ll be able to do it.” Demand for bioplastics also needs to grow among retailers and consumers, according to Coke.
