Expert Meeting on Biomass Waste Valorisation
for Resilient Cities on 28–29 Oct 2025

NUS Environmental Research Institute (NERI), together with the Chair of Circular Economy and Recycling Technology (CERT) at Technische Universität Berlin (TUB) and the Office of the Deputy President (Research and Technology) (ODPRT), National University of Singapore (NUS), jointly organised the Expert Meeting on Biomass Waste Valorisation for Resilient Cities on 28–29 Oct 2025. The meeting was supported by the Berlin University Alliance (BUA) and the Centre for Environmental Resilience (CER), NUS Civil and Environmental Engineering.

We convened a curated group of ~20 researchers, practitioners, and policy thinkers from NUS, TUB, and strategic partner institutions to advance circular bioeconomy solutions for cities. The meeting was coordinated by Asst Prof Iris Yu, Dr Lee Lai Yoke, and Dr Terence Tan (NUS), and Li Wah Wong and Prof Vera Susanne Rotter (TUBerlin). We extend our sincere thanks to all participants—especially Pui Cuifen and Tan Hang Chong—for sharing the community-led initiatives that convert biomass waste into resources for community gardens.

Key topics discussed:

  • Technology progress in biomass valorisation and bio-based materials, with a focus on scalability and life-cycle impacts in urban contexts.
  • Frameworks for implementation, quality assurance, and multi-level adoption, including governance, certification, and community-driven innovation.

Target outcomes:

  • Catalyse transdisciplinary solutions for a circular bioeconomy, integrating science, engineering, and policy.
  • Develop scalable biomass valorisation pathways across tropical urban contexts—from feedstock characterisation to conversion (gas, liquid, solid) and product upgrading.
  • Establish harmonised life-cycle, techno-economic, and risk assessment frameworks, with shared data standards.
  • Translate innovations through pilots and living labs with public agencies and industry, building bilateral testbeds in Singapore and Germany.
  • Enable adoption via policy, standards, and market design, while building capacity through talent exchanges.

We look forward to catalysing impactful partnerships and translational projects that turn waste into resilient urban value for Singapore, Germany, and beyond.
