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 per cent in the next five years, according to the European Bioplastics Association in Berlin, whose members include Cargill Inc. and Mitsubishi Chemical Holdings Corp. German chemical giant BASF SE and the Finnish paper maker Stora Enso Oyj have stepped into the business to meet demand from the likes of Coca-Cola Co. to Lego A/S.
“Biochemicals and bioplastics could erode a portion of oil demand, much like recycling can erode overall virgin plastics demand,” said Pieterjan Van Uytvanck, a senior consultant at Wood Mackenzie, a research group focused on the oil industry. “Provided the challenges facing biomass today are overcome, it will become a larger portion of the supply.”
Moviegoers famously learned in the 1967 film “The Graduate” that “there’s a great future in plastics.” Oil companies make ethylene and other basic building blocks for plastic. They’ve been eyeing that market for growth as electric cars threaten to trim demand for gasoline.
Plastic material’s ubiquity in packaging has left the world literally swimming in disused bottles, bags and wraps. That’s starting to worry both environmentalists and the companies that use it the most. There’ll be more plastic than fish in the world’s oceans by 2050, according to the Ellen MacArthur Foundation, and those materials are finding their way into the food chain.
Bioplastics currently make up about one per cent of the plastics market, according the industry’s organization in Europe. They are made by processing sugars from plants and tend to have a smaller carbon footprint than their conventional counterparts. Some are also designed to naturally degrade after use. Top producers include Sao Paulo-based Braskem SA, NatureWorks LLC in the U.S. and Novamont SpA of Italy.
“Attitudes are evolving,” said David Eyton, the head of technology at BP Plc. “The question that faces the petrochemicals industry that has yet to really be answered is, ‘How are people going to deal with some of the environmental impacts of petrochemicals? Particularly plastics, which are a growing concern.’”
The International Energy Agency forecasts that growth in the plastics market should boost petroleum demand. It takes about 8.5 barrels of oil-derived naphtha to produce the a ton of ethylene needed to manufacture 160,000 plastic bags, according to Bloomberg Intelligence calculations.
“Petrochemicals will take center stage in driving oil demand,” said IEA analyst Tae-Yoon Kim. “This is why oil majors are very much focusing on petrochemicals.”
Saudi Arabian Oil Co., Exxon Mobil Corp., Royal Dutch Shell Plc and Total SA are expanding their plastic footprints, according to the IEA.
“We’re expecting petrochemicals to grow four per cent per year,” said Ahmad Al Khowaiter, chief technology officer at Saudi Aramco. “That’s an opportunity we’re really trying to leverage.”
Alternatives to traditional plastics are appearing:
- BASF set up a JV with Avantium Holding BV last year and is making bottles from cornstarch at a pilot plant. The partners are planning a plant with a capacity of 50,000 tonnes per year in Belgium.
- Coca-Cola, focusing on sustainability of plastic in packaging, has sold more than 50 billion so-called PlantBottles. Packaging contains 30 per cent bioplastic.
- Stora Enso wants to reinvent itself as a renewable materials company. It sold close to 10 billion euros of paper and cardboard products last year and has a research centre in southern Sweden where it’s testing plastic that’s 50 per cent wood fiber. A mill in eastern Finland makes yarn from wood pulp.
- Lego allocated one billion kroner (US$160 million) to research more sustainable materials for its building blocks.
The new technology will have to compete against massive refineries that convert hundreds of thousands of barrels of every day into plastics.
“Alternative raw materials must be competitive,” Stora Enso’s chief financial officer Seppo Parvi said in an interview in London, 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.
“It won’t ever work if there’s just one big consumer company like a Coca-Cola trying to drive suppliers,” said Ben Jordan, head of environmental policy at Coca-Cola. “You need more demand out there in industry.”
