The Circonomics Training Book is a practical guide designed to help small and medium-sized enterprises (SMEs) in the Philippines and across ASEAN adopt circular economy practices for plastics. Developed by the Regional Knowledge Centre for Marine Plastic Debris (RKC-MPD) under ERIA, the book examines the impacts of linear business models and provides actionable tools for redesigning products, reducing plastic waste, improving eco-design, and integrating recycling and extended producer responsibility (EPR) frameworks.

It features regional case studies, hands-on exercises, and step-by-step guidance to help SMEs strengthen supply chains, optimise resource use, and tap into emerging financing opportunities within the circular economy for plastics. By equipping enterprises with practical strategies and contextual insights, this publication supports ASEAN’s broader objective of advancing plastic circularity and building a more sustainable and resilient regional economy.
