Sharing the Japan Model
for Plastic Resource Circulation
with the World

Solving marine plastic pollution requires not only addressing plastics that have already accumulated, but also building systems across society—beyond national and regional boundaries—to prevent further leakage into the environment.

Guided by a shared vision, CLOMA brings together the technologies and expertise cultivated by Japanese industry. Through public–private collaboration, CLOMA promotes the circular use of plastics, centered on the 3Rs (Reduce, Reuse, Recycle) and alternative materials.

By engaging consumers and society, CLOMA promotes the Japan Model on the global stage—positioning it as a Japan-originated solution for realizing a circular society and eliminating plastic waste leakage into the oceans.

A Carbon-Neutral,
Nature-Positive Future

As part of its activities, CLOMA promotes a circular economy through the Japan Model of plastic resource circulation. CLOMA extends its focus beyond industry to consumer lifestyles, supporting the transition to a more sustainable and resource-efficient society.

By reducing use of fossil resources and accelerating the shift to non-fossil alternatives— such as biomass—for raw materials and fuels, we can contribute to carbon neutrality while preventing the loss of biodiversity.

It also works to prevent the leakage of plastic waste into the environment, striving to achieve clean oceans and a nature-positive future.

Creating New Innovation
Through Corporate Collaboration

CLOMA is an alliance that brings together a diverse range of stakeholders, including companies, partner organizations, local governments, relevant ministries, and observers. Organizations from different industries and with distinct roles unite to address a shared societal challenge.

Taking a comprehensive view of the entire plastic lifecycle—from materials and manufacturing to distribution, collection, and recycling—participants contribute their respective expertise and strengths to drive practical collaboration that transcends organizational boundaries.

Through these collaborations, CLOMA fosters innovation that goes beyond technological development to achieve real-world implementation, including new systems and frameworks that no single organization could create alone.
