Marine debris collection and ocean cleanup
Recycling of runoff waste

summary
The company collects and recycles plastic waste that is difficult to recycle, such as litter that has drifted ashore, and plans and manufactures upcycled products. In addition, the company gives special classes on marine plastic waste at educational institutions such as elementary schools and companies, introducing its initiatives. The company also provides information on how familiar items can cause marine pollution and the measures that can be taken to prevent it.
Technical Strengths
The company's strength lies in its technology that can produce plastic boards with performance equal to or better than wood at low cost, eliminating the processes of sorting, washing, and pelletizing that are indispensable for material recycling of plastic waste. The technology has a wide range of applications, including the ability to mix not only plastic waste but also plasterboard and rubber chips. It is also spreading to waste from factories and construction waste.
