Definition of bioplastic
"Biodegradable plastics" that are biodegraded by microorganisms and "biomass plastics" that are manufactured from biomass are collectively called "bioplastics."
- Japan Bioplastics Association (JBPA): A private organization established in 1989

Biomass pressure sensitive adhesives
Biomass pressure sensitive adhesives are able to reduce CO2 more than existing normal products. It is causative substance of global warming, but plants as raw material absorb CO2 when they grow up. Therefore it will not increase as total if you burn final adhesive coated product for dispose. This concept is based on "Carbon neutrality".

About biodegradability test
The following biodegradability test methods have been published by ISO, and JIS standards corresponding to each have been published.
- Compost decomposition: Decomposes in special equipment (high temperature and humidity)
ISO 14855-1 (JIS K6953-1)
→ TOYOCHEM: Biodegradable pressure sensitive adhesives, Toyo-Morton: Biodegradable adhesives
ISO 14855-2 (JIS K6953-2) - Soil decomposition: decomposition in soil
ISO 17556 (JIS K6955) - Aqueous decomposition: decomposes under freshwater conditions
ISO 14851 (JIS K6950)
ISO 14852 (JIS K6951) - Marine biodegradation: Decomposition in seawater
ISO 18830
ISO 19679
*Neither corresponds to JIS standards.
About marine biodegradation test
About marine biodegradation
TUV Austria: A private certification body that certifies marine biodegradation.
In laboratory tests, 27 products (as of March 2020) have been certified to biodegrade by more than 90% within 6 months in seawater at 30°C and meet various conditions (non-toxicity, etc.).
About the difference in biodegradation
The amount of bacteria varies depending on the environment. Biodegradation progresses relatively easily in environments where large amounts of bacteria exist, such as in compost environments, garbage (activated sludge), and soil.
➝There are very few bacteria in seawater, making it difficult for biodegradation to proceed.
