APEC ACABT executed the project PPSTI 06 2021A - Green Synergy Solutions for Sustainable Community on Agriculture Residue-Based Energy and Circular Economy for capacity building of participants from APEC economies. The review presented the issues of Bio-wastes to Green Hydrogen/methane and Bio-circular Economy. The events included Policy Dialogue, Workshop I - Lectures, Workshop II - Young Entrepreneurs Training Program, and On-site Technical Practice (Self-Fund) on 15-17 September 2022. The hybrid events were on-site in Chinese Taipei and online on Cisco WebEx, with 106 participants from 12 APEC member economies and a Non-APEC member at the events. Throughout these events, the participants acquired more information on green energy policies from Policy Dialogue, advanced green synergy technologies from Workshops I and II, and the HyMeTek knowledge and experience from On-site Technical Practice. These have built their capacity to solve environmental and social issues through green synergy in the APEC region.
