Mitsui Chemicals working on commercialisation bio-PP

December 06/2019

MOSCOW (MRC) -- Mitsui Chemicals, Inc. is collaborating with Kaisei Inc. on a project aimed at the development of bio-PP at commercial scale. The project has been adopted by Japan's Ministry of the Environment as part of its plans for a carbon-free society ambition, reported BioplasticsMagazine.

Mitsui Chemicals' bio-PP pilot project will aid in the countrys effort to reduce greenhouse gas emissions.

The Ministry of the Environment is further supporting a carbon-free society by accelerating the construction of resource recycling systems for plastics and other materials. This project will run trials for switching to renewable resources as a substitute for petroleum-derived plastics as well as for building recycling processes for plastics and other materials.

Mitsui Chemicals will therefore be conducting the world's first bio-PP industrialization demonstration test. This will involve conducting numerous and varied evaluations of technologies, quality, economic efficiency, and environmental impact such as GHG reduction. After solving these issues, Mitsui Chemicals Group will consider commercializing the production of bio-PP. Production,  said the company, will start in 2024 at the earliest. The project will be part of the expansion of the companys so-called Blue Value products , or environmental contribution value products, based on its climate change policy and plastic strategies. In 2015, Mitsui developed the environmental contribution value, Blue Value, to achieve its goal of realizing a "cohesive society in harmony with the environment". Under the unique environmental impact assessment criteria Blue Value Index, the Mitsui Chemicals Group certifies products and services as having Blue Value that are deemed to reduce CO2, protect resources, and harmonize with nature, thereby contributing to the environment in three elements.

"We aim to commercialize bio-PP, which has yet to be produced from biomass unlike other major resins We will build a circular model throughout the manufacturing supply chain to significantly reduce CO2 emissions," the company announced in a statement released 26 September.

Polypropylene has a wide range of applications, spanning automobile-parts to medical care products, home appliances, housing and food products, and accounts for more than 20 percent of the plastic produced in Japan. However, due to technical difficulties, production of polypropylene from biomass has not been established at the industrial level.

Conventional plastics are produced from fossil resources that have been stored underground for mhundreds of millions of years, while bioplastics are primarily derived from plants. Since plants absorb CO2 from the atmosphere to grow, they offer a more effective way to reduce CO2 emissions, thus helping to mitigate global warming. Bio-PP derived from plants is a product expected to contribute to a more sustainable society.

The new production route towards commercialization involves the fermentation of various type of biomass - mainly non-edible plants - to produce isopropanol (IPA), which is then dehydrated to obtain propylene in a first-of-its-kind IPA method. Compared to other biomass production approaches studied by other companies thus far, this could prove to be a more cost-effective way to manufacture bio-PP.

Kaisei Inc. will cultivate biomass raw materials used by Mitsui Chemicals, collect wastes generated from biomass raw materials, and supply electricity to manufacturing facilities and manufactures fertilizers through its effective use. By collaborating with Kaisei Inc., Mitsui Chemicals aims to contribute to society through environmentally friendly action with a circular model that leverages the supply chain.

As MRC informed before, Mitsui Chemicals restarted its naphtha cracker in Japan on 11-12 May, 2019, following an unplanned outage. The cracker was shut in end-April, 2019 owing to power failure. Located at Chiba in Japan, the cracker has an ethylene capacity of 600,000 mt/year and propylene capacity of 331,000 mt/year.

According to MRC's ScanPlast report, the estimated PP consumption in the Russian market in January-October 2019 totalled 1,066,520 tonnes, up by 7% year on year. Supply of block copolymers of propylene (PP block copolymer) and homopolymer of propylene (homopolymer PP) increased, demand for statistical copolymers (PP random copolymer) decreased.

Mitsui Chemicals is a leading manufacturer and supplier of value added specialty chemicals, plastics and materials for the automotive, healthcare, packaging, agricultural, building, and semiconductor and electronics markets. Mitsui Chemicals is a Japanese Chemicals company, a part of the Mitsui conglomerate. The company has a turnover of around 15 billion USD and has business interests in Japan, Europe, China, Southeast Asia and the USA. The company mainly deals in performance materials, petro and basic chemicals and functional polymeric materials.
