Japanese firm develops cellulose-based resin
Environmental problems such as plastic pollution, global warming due to human population explosion, are getting severe in the world and especially the microplastic problem in the marine environment is becoming a devastating issue. It is predicted that the amount of plastic garbage will be more than that of fish in the world by 2050. There are also some scientific reports that these microplastics are already in our human body. Therefore, plastic recycling, reduction of plastic usage itself, and biodegradable plastic usage and development, have been intensively challenged and carried out.
In this regard, in a project led by Dr. Ryohei Mori, Japanese firm Green Science Alliance Co. has developed biodegradable textile, fibre, yarn, film with cellulose-based resin. The company has also applied its nano cellulose composite technology into this cellulose based material, and made so to speak "cellulose + nano cellulose" material and products.
Green Science Alliance had confirmed previously that mixed nano cellulose in the biodegradable resin can increase biodegradability. This "cellulose + nano cellulose" resin is said to be “a very interesting new type of biodegradable resin material”. In addition, cellulose can be said to be an environmentally friendly biodegradable resin since most of biodegradable resins are composed of either petroleum or edible biomass. Using edible biomass such as corn, sugarcane, potato, etc. as raw material can be risky since they compete with human nutritious food.
Dr Mori has said the company will keep making an effort to improve resin properties such as mechanical properties, moulding properties, etc., in order to create “good biodegradable resin fibre, yarn, film, as well as non-woven”.
