Environmental problems such as climate change, deforestation, extinction of species, water and food shortage etc., due to the explosion of the human population, are becoming increasingly severe worldwide. Plastic pollution is an especially severe environmental problem which cause adverse effects; nanoplastics, in particular, are already present in the human body as a result of breathing polluted air and though our meals. For example, we are ingesting nanoplastics through drinking water with PET bottles. Recently, there have been some medical studies reporting the enhanced risk of heart attack caused by nanoplastics in blood vessels. In addition, they may also possess ill effects for the immune system, as well as cause an inflammation reaction in the digestive system (Figure. Nano-plastics Pollution Risk to Human Health).

The production and usage of biodegradable plastic is slowly increasing, although greater than 90% of plastics worldwide are still petroleum-based non-biodegradable plastics. In addition, the production of these petroleum-based non-biodegradable plastics are still increasing regardless of these plastic pollution problems. Therefore, plastic pollution is worsening each year.

On the other hand, biodegradable plastics can biodegrade and return back to nature and do not become plastic pollution; although biodegradability needs to be carefully examined in various types of conditions including compost condition, soil, water, sea water etc. However, biodegradable plastics including PLA (polylactic acid), lactone-based materials are already applied for medical usage in the human body. When biodegradable plastics are made from plants, since plants absorb CO₂ from the surrounding atmosphere, the amount of CO₂ emission will be less than that of petroleum-based plastics. Because the status of CO₂ is circulating so that they can be regarded as carbon neutral.

One of the goals for Green Science Alliance is to replace all the petroleum based materials with plant biomass alternatives, as Dr. Ryohei Mori, CEO of the company, wrote the scientific article which made front cover page of British scientific journal "RSC Sustainability." 

Replacing all petroleum-based chemical products with natural biomass-based chemical products: a tutorial review - RSC Sustainability (RSC Publishing)

Based on his concept, Green Science Alliance has been making an effort to develop various types of plant organic biomass based materials such as biodegradable plastics, resins, coatings, paints, glue, plasticizer, lubricant, biochar, nanocellulose, 3D printer materials and products, etc. And this time, Mr. Daiki Tanaka and Dr. Ryohei Mori have made biodegradable film bags with plant based resins. There are already some plant based film bags in the market but they are not biodegradable so that they can be nano-plastic pollution if they are thrown away after usage. But Green Science Alliance's film bags are not only plant based but also biodegradable. The plant biomass content is 50% - 60%, although they will keep challenging to make the biomass content higher.

The product is printed with company trademark "Bio Sakura"; however, they can also print different a logo or design as the customer requests.
