BESS Conference on Zero Waste and Circular Economy will be held in Dec 2021 online via Zoom. In a region full of biomass resources, Singapore lies in the center of South East Asia where biomass and biomass wastes are generated in large amounts. Additionally, the population of the region is currently at 675 million and growing at a rapid pace, correlating with a similar growth in waste generation. However, most countries now dispose these wastes in environment-unfriendly and unsustainable manners, like landfills, incineration or just discarding into open land or in the ocean. These methods generate significant greenhouse gas emissions and create future health hazards, in addition to killing wildlife and sea creatures. Therefore, the goal of achieving zero waste and using circular economy concepts for waste management has been of growing interest for many governments, including Singapore which launched its Zero Waste Nation goal in 2019. In this conference, we will explore these concepts and study the significant uses and potential for wastes towards achieving the Zero Waste goal using biotechnology and bioprocessing methods.

Conference Topics include:

  1. Bioprocessing biotransformation and fermentation
  2. Palm oil upgrading and waste utilization
  3. Sustainable food processing and technology
  4. Food waste upcycling, treatment, and management
  5. Biomass conversion and utilization
  6. Bio-based chemicals
  7. Synthetic biology, systems biology and metabolic engineering
  8. Life cycle analysis
  9. Entrepreneurship and industries

Conference keynote speakers and organizers information is available below. Conference Proceedings can be found HERE. More details will be updated later. 

Come and join us for this networking event and hear from the experts on zerowaste and circular economy from Southeast Asia and around the world.

We look forward to meeting you online.
