About us
CEO Message

PET REFINE TECHNOLOGY’s cutting edge chemical recycling technology makes it possible to produce PET from any level of used PET bottles which are mainly manufactured from petroleum-based materials. This recycling technology even allows bottles that contain a high level of impurities so that they are considered difficult to recycle, to be recycled into new, safe and secure PET bottles again and again and again.
Since its establishment in 2008, the company has played a role in the bottle-to-bottle cycle in Japan. We have joined JEPLAN Group since 2018 and have made a fresh start with the goal of complete recycling of used PET bottles as one of the members to realize JEPLAN's vision of “everything back into circulation”.
Because of efforts of consumers, Japan has been successfully collecting used PET bottles. PET REFINE TECHNOLOGY challenge to create a society that used plastic bottles can be continuously used, thereby contribute to the reduction of fossil fuel consumption and carbon dioxide emissions, which are considered to be one of the causes of global warming. In order to pass on this world to the next generation for their healthy living, we commit to challenge of realizing the complete recycling of PET bottles.
We would like to thank you for your continued support of PET REFINE TECHNOLOGY's activities.
