American start-ups use methane to produce environmentally friendly plastics

methane is a strong greenhouse gas. If it is used to make plastic products, it can not only remove air pollution, but also replace oil. Although science has long known this possibility, how to reduce costs and carry out commercial production is a big problem. Recently, in the United States, a small start-up company called new light technologies announced a breakthrough

the company said that it has found an alternative way to use methane from farm animal manure to make plastic. At present, it has reached plastic supply contracts with large enterprises such as Dell and L'Oreal, and the plastic made of methane can be made into packaging, chairs and other products. Markherrema, CEO of the company, said that the price of plastic produced by the company is lower than that of traditional plastics, and he hopes to bring about a revolution in the plastic industry, thereby reducing greenhouse gas emissions. We should pay attention. "We believe that we can achieve a win-win situation in economy and environmental protection," he said

herema 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, Xinguang Technology Co., Ltd. is currently small, and subsequent visitors can also see a large investment in the subversive new figure 4 production platform of 3D system company. After being transported to the plant of Xinguang technology company, methane is pumped into the reactor together with air and biocatalyst independently developed by the company

David Valentine, a professor at the University of California, Santa Barbara, pointed out that the methane used by Xinguang technology company comes from places such as dairy farms and waste landfills, rather than commercial markets, which may hinder the expansion of scale. The company itself will not have a great 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 main greenhouse gases leading to global warming. In the United States, designed for hard polymer requirements, agriculture is the main source of methane emissions. According to the U.S. Environmental Protection Agency, more than one-third of methane gas in the United States comes from dunghill or the digestive system of livestock, such as cattle, buffalo, sheep and goats. At present, most plastic products in the United States are made of ethane extracted from natural gas, while the rest of the world mainly uses oil to make plastics

Goetz veser, a methane plastic technology expert and professor at the University of Pittsburgh, said that for decades, how to accurately locate and convert methane into higher hydrocarbons has been a major problem in the industry
