The aims of this Task are consistent with the overall IEA Bioenergy Strategic Plan and include ongoing initiatives to:

  • Promote market deployment of technologies and systems for sustainable energy generation from biomass.
  • Raise public awareness through communication with key stakeholders for the use of biomass as an energy source and to provide clear and verified information on bioenergy.
  • Strengthen the outreach efforts to the Implementing Agreement to involve interested new country members, industry and multilateral organisations.
  • To increase dissemination and information.

Task 36 objectives for the 2022-2024 triennium

During 2022–2024, Task 36 will focus on the effect that circular economy initiatives along the waste and energy value chain will have in the deployment of bioenergy globally.

The specific objectives for the proposed programme are:

  • Understanding economic, societal, and environmental aspects derived from different EfW and material recycling technologies/strategies adopted.
  • Highlight the role of EfW in a circular economy.
  • Evaluation of new technologies pathways for turning waste into high valuable products.
  • Forecast waste streams composition and amounts generated as circular economy is unfolding.
  • Raise awareness within the waste and energy sector about the role of smart/digital technologies in enabling transition of sectors to circularity.

Work programme will include

Within the three-year timescale of the Task, the Work Programme will include:

  • Task meetings to exchange results from relevant national R&D programmes
  • Field trips associated with the Task meetings, including visits to state-of-the-art facilities (if possible)
  • International workshops (physical and/or on-line) associated with the Task meeting, to cover integration of WtE and material recycling/recovery in industry; sustainability; public acceptance; policies to support waste-to-resource management; sewage sludge valorisation; and high value products from waste.
  • Specific actions resulting in discussions of Resource recovery from residues generated by EfW;
  • Two strategic project – see outline below
  • Information exchange with other IEA Bioenergy Tasks and other international networks on relevant energy from waste technologies worldwide
  • ExCo interaction and support


The following deliverables will be primarily aimed at decision makers who impact the development of energy from waste:

  • Four topic reports about:
    • Sustainability
    • Smart sorting technologies
    • Food waste- current practices and future solutions
    • Future scenarios: new waste streams, their composition, and amounts
  • Two case studies  about:
    • “Potential synergies between WtE and material recycling”
    • “Environmental performance of different waste management strategies”
  • A series of six international workshops and their respective summary reports. Topics for these events are:
    • Integration of WtE and material recycling/recovery industry
    • Sustainability metrics
    • Public acceptance
    • Sewage sludge valorisation
    • Framework for strengthening waste to resource management
    • High value products from waste
  • Collaboration with Task 40 in the strategic project “The potential of carbon capture and utilisation (CCU) within WtE”
  • Collaboration with other tasks in the strategic project “Hydrogen from waste”
  • Final report summarizing all the content collected/generated during the triennium.
  • Newsletters
  • Webinars under IEA Bioenergy (to be determined)
