勝光山鉱業所 List of Products and Services

We would like to introduce a case where "film and sheet bio-material pellets" were produced using 100% biomass resin (bioplastics). By incorporating 51% mineral filler, we can mold thin sheets with a thickness of 0.04 to 0.05 mm, achieving a departure from 100% petroleum-derived materials. Additionally, by combining this resin with biodegradable resin, we can accommodate a variety of applications. We assist brand owners in realizing their sustainability efforts (such as reducing petroleum-derived resins and CO2 emissions) and in communicating information on reducing environmental impact through material substitution in waste disposal scenarios. 【Case Overview】 ■ Usage scenarios: Multi-sheets and garbage bags disposed of as waste in agricultural settings, or packaging sheets for gift plastic materials. ■ Industries: Agriculture, garbage bag industry, gift packaging industry, etc. *For more details, please download the PDF or feel free to contact us.

• Biodegradable plastics

We would like to introduce a case study where "cutlery/tableware bio-material pellets" were produced using 100% biomass resin (bioplastic). By incorporating 80% high concentration of oyster shell powder and wood powder, and combining the resin with bio-materials, we achieved a 100% bio-material (excluding additives) that is environmentally friendly and suitable for injection molding. We assist brand owners in realizing their sustainability efforts (such as reducing petroleum-derived resins and CO2 emissions) and in communicating information on reducing environmental impact through food-related settings by replacing materials. 【Case Overview】 ■ Usage scenarios: Disposable situations or repeated use scenarios for spoons, forks, chopsticks, tableware, etc. ■ Industries involved: Convenience store industry, event industry, school lunch industry, etc. *For more details, please download the PDF or feel free to contact us.

• Biodegradable plastics

We would like to introduce a case study of the production of "bio-material pellets for liquid bottles" using 100% biomass resin (bioplastics). By blending 80% high-concentration powder from oyster shells and wood powder, and combining it with bio-material resin, we achieved a 100% bio-material (excluding additives) that is suitable for blow molding, making it an environmentally friendly material. We assist brand owners in their sustainability efforts (reducing petroleum-based resins, reducing CO2 emissions, etc.) and help communicate information on reducing environmental impact through the replacement of materials in everyday life. 【Case Overview】 ■ Usage scenarios: Bottles for detergents, liquid soaps, shampoos, conditioners, etc. ■ Industries: Toiletries industry, shampoo industry, etc. *For more details, please download the PDF or feel free to contact us.
