Mitsui Chemicals is working with Kaisei on a project to develop commercial-scale biopolypropylene. According to the Journal of Bioplastics, the project has been adopted by the Japanese Ministry of the Environment as part of its carbon-free society goal plan.
Mitsui Chemicals' bio-polypropylene pilot project will help Japan reduce greenhouse gas emissions.
The Japanese Ministry of the Environment is further supporting a carbon-free society by accelerating the construction of a resource recovery system for plastics and other materials. The project will carry out trials to switch to renewable resources as an alternative to petroleum-derived plastics, and to establish recycling processes for plastics and other materials.
Therefore, Mitsui Chemicals will conduct the world's first industrial demonstration demonstration of bio-polypropylene. This will involve a large and diverse assessment of technology, quality, economic benefits and environmental impacts (such as greenhouse gas reductions). After addressing these issues, Mitsui Chemicals Group will consider commercializing the production of bio-polypropylene. The company says production will begin as early as 2024. The project will be part of the company's so-called "Blue Value Products" or "Environmental Projection Value Products" expansion plan based on its climate change policy and plastics strategy. In 2015, Mitsui developed the "Blue Value", an environmental contribution value, to achieve its goal of "a cohesive society living in harmony with the environment". According to the unique blue value index of the environmental impact assessment standard, Mitsui Chemicals Group's certified products and services have blue value and are considered to reduce carbon dioxide, protect resources, and live in harmony with nature, thereby contributing to the environment in three ways.
The company announced in a statement issued on September 26: "Our goal is to commercialize biopolypropylene. Unlike other major resins, biopolypropylene has not yet been produced from biomass. We will be in Establish a circular model throughout the manufacturing supply chain to significantly reduce carbon dioxide emissions. "
Polypropylene has a wide range of applications, from automobile parts to medical care products, household appliances, housing and food products, accounting for more than 20% of Japan's plastic production. However, due to technical difficulties, the production of polypropylene from biomass has not yet been established on an industrial level.
Traditional plastics are produced from fossil resources stored hundreds of millions of years underground, while bioplastics are mainly derived from plants. Because plants absorb carbon dioxide from the atmosphere for growth, they provide a more effective way to reduce carbon dioxide emissions, which can help alleviate global warming. Biopolypropylene extracted from plants is a product that is expected to contribute to a more sustainable society.
A new production route towards commercialization involves fermentation of various types of biomass (mainly non-edible plants) to produce isopropyl alcohol (IPA), which is then dehydrated by the first IPA method to obtain propylene. Compared with other biomass production methods studied by other companies so far, this may prove to be a more cost-effective method for producing biopolypropylene.
Kaisei will plant biomass raw materials used by Mitsui Chemicals, collect waste generated from biomass raw materials, provide power to production facilities, and produce fertilizer through its effective use. By cooperating with Kaisei, Mitsui Chemicals aims to contribute to society through environmental protection actions by utilizing the recycling model of the supply chain.
As MRC previously knew, after an unplanned shutdown, Mitsui Chemicals restarted its naphtha cracking unit in Japan from May 11-12, 2019. At the end of April 2019, the cracker was shut down due to a power outage. The cracker is located in Chiba, Japan, with an ethylene production capacity of 600,000 metric tons / year and a propylene production capacity of 331,000 metric tons / year.
Mitsui Chemicals is a leading manufacturer and supplier of value-added specialty chemicals, plastics and materials for the automotive, healthcare, packaging, agriculture, construction, and semiconductor and electronics markets. Mitsui Chemicals is a Japanese chemical company that is part of the Mitsui Group. The company has a turnover of approximately $ 15 billion and has business interests in Japan, Europe, China, Southeast Asia and the United States. The company mainly deals in performance materials, petroleum and basic chemicals, and functional polymer materials.
