Sumika Sustainable Solutions

Mankind faces serious issues such as climate change and the food problem. The world places expectations on companies that take on the challenge of resolving these issues.

With the serious problems facing us now, the Sumitomo Chemical Group reaffirms its corporate mission of contributing to society through its business activities. We identify certain kinds of our products and technologies as “Sumika Sustainable Solutions” that offer technology-based new value in solving the problems to help build a sustainable society. We promote the development and use of these products and technologies.

Sumikaexcel™, polyethersulfone

Solution

Sumikaexcel™PES is one of high performance engineering plastics and has excellent properties in heat resistance, dimensional stability, flame resistance, and hot water resistance. It is used to give toughness to carbon-fiber reinforced plastics (CFRP) for aircraft as an indispensables material to improve aircraft performance. CFRP is used in the main wings, tail wings and body of an aircraft, reducing the weight of aircraft parts by 30 to 40 percent compared with those using conventional materials. It thus improves aircraft fuel efficiency and contributes to reducing greenhouse gas emissions.

UV lamination for polarizer (manufacturing) process

Solution

UV lamination is a new manufacturing process for polarizing film with ultraviolet curing technology. The conventional process uses water-soluble glue and its curing requires a long process of drying by heating. UV lamination can omit this process, achieving substantial energy saving and contributing to greenhouse gas emissions reductions.

SUMIMET™, feed additive methionine

Solution

Methionine is an amino acid that poultry tend to lack most when they grow. We need to give poultry feed to which methionine alone is added to make up for a deficiency, or feed with a high content of high-protein, methionine-containing ingredients, such as fishmeal. When the latter feed was given, amino acids except methionine become excessive and are released into poultry excrement as nitrogen compounds, leading to the generation of nitrous oxide (N2O), a greenhouse gas. By adding methionine alone to fill up a deficiency, the amino acids that poultry need for growth are given in proper amounts, thus reducing nitrogen in poultry excrement and cutting greenhouse gases. Methionine also helps reduce environmental burdens such as an odor due to ammonia emission and soil and water pollution derived from nitrogen in excrement.

Sumikathene™ EP and Excellen™ GMH, polyethylene used for refill pouches

Solution

Sumikathene™ EP and Excellen™ GMH are polyethylene used for refill pouches for shampoo, dish detergent, and liquid laundry detergent. Compared with rigid plastic bottles of the same size, these pouches use a smaller amount of plastic, thus contributing to resource savings.
