– Aiming to Build a New Social System for Resource Recycling –

  SEKISUI CHEMICAL CO., LTD. (President and Representative Director: Keita Kato; hereinafter, “SEKISUI CHEMICAL”) has launched the new brand “UNISONTM” (trademark registration pending) for the biorefinery business that uses microorganisms to convert municipal/industrial waste into resources. Through the promotion of UNISONTM, SEKISUI CHEMICAL aims to create a new resource recycling social system with the participation of a wide range of stakeholders as partners.

  The various materials used when creating things are all gifts from the earth. Because these resources are limited, they are returned to the earth once they have fulfilled their roles, given a new life and recycled. This is how SEKISUI CHEMICAL wants to run society together with the earth and connect lifestyles with life.
  The name “UNISONTM” expresses the desire for the earth and humanity, nature and chemistry to work together and resonate with each other like a chorus. In addition, “Unique Solution for NatureTM” represents an unparalleled solution for plastic resource recycling, with the starting letters of each word forming the name “UNISON.”

  “UNISONTM” is a biorefinery business brand that uses microbes to create resources from municipal/industrial waste through BR ethanol technology and other methods. This revolutionary technology, the first of its kind in the world, turns combustible waste collected at waste disposal facilities into gas without the need for sorting , and converts the gas into ethanol using microbes developed by U.S. company LanzaTech NZ, Inc. without the use of chemical catalysts, heat or pressure. It is expected to make a significant contribution to the realization of a sustainable society by helping to reduce the use of fossil resources, curb CO2 emissions, and resolve the issue of marine plastic waste.

  To achieve the “new social system for resource recycling,” SEKISUI CHEMICAL is aiming to establish a new recycling system that returns discarded waste into materials so that they can be reused repeatedly. This will require collaboration by a wide range of participants (corporations, local municipalities, consumers, public authorities etc.). The aim is to extensively promote co-creation for a sustainable society.
