US startups say available methane to produce environmentally friendly plastics

Methane is a powerful greenhouse gas. If it is used to make plastic products , it can remove air pollution and replace oil. Although this possibility has long been known in science, how to reduce costs for commercial production is A big problem. Recently in the United States, a small startup called Newlight Technologies announced a breakthrough. The company said it has found an alternative way to use plastics from farm animal manure to make plastics. It has already reached a supply contract with large companies such as Dell and L'Oreal, and plastics made from methane can be used for packaging, chairs, etc. product. Mark Herrema, the company's chief executive, said that the plastics produced are cheaper than traditional plastics and hope to revolutionize the plastics industry, thereby reducing greenhouse gas emissions.
Herrema said that its products have two advantages over traditional petrochemical plastic products: First, the raw materials of the products can reduce air pollution, and second, the price is lower. However, Shinko Technology is currently small and requires substantial investment. After the methane is transported to the Shin Kong Technology plant, it is pumped to the reactor together with the air and the company's self-developed biocatalyst.
In addition, David Valentine, a professor at the University of California, Santa Barbara, points out that the use of methane by Sunbeam Technologies is from dairy farms and landfills, rather than commercial markets, which may hinder The expansion of scale. The company itself will not have a major impact on reducing greenhouse gas emissions, but a small amount of emission reduction is also helpful.
Methane is the largest component of natural gas and one of the major greenhouse gases that contribute to global warming. In the United States, agriculture is the main source of methane emissions. According to the US Environmental Protection Agency, more than one-third of all methane gas in the United States comes from the digestive system of manure or livestock, such as cattle, sheep and goats. At present, most plastic products in the United States are made of ethane extracted from natural gas, while other parts of the world mainly use petroleum to make plastic.
