Building blocks from waste

As part of the circular economy, there is an increasing interest in converting waste streams into feedstock (hydrocarbons) and energy carriers (biogas, syngas, oil, heat, hydrogen). The program Building blocks from waste aims to match under-utilized residual streams with the most suitable conversion technologies.

There are many different technologies under development for the conversion of complex residual streams into energy carriers and/or smaller building blocks. How these technologies fit with the characteristics of each of the complex residual streams is often unknown.

Converting residual streams

The Building blocks from Waste Matchmaking Event in 2021 marked the starting point for a new platform. The objective of this platform is to exchange knowledge and expertise on innovative technologies to assist the owners of residual streams in judging on – or distinguishing between – the applicability of different technologies, or the potential market of the resulting (mixture of) components.

Challenges on making waste economic feasible

Participants indicate that low economic feasibility and lack of market for the products are the main reason for the low valorisation potential. Also, the need for a continuous high volume and the fluctuating prices are seen as hurdles.

Other challenges mentioned are:

  • Waste incineration is too cheap, hindering better technologies to develop
  • Getting same legislation for waste incineration as for other emitting industries
  • Scale-up towards commercial scale
  • Fate of contaminants in the streams
  • Additional side-streams arising from the conversion processes
  • Finding general solutions for many small streams
  • Financing

ISPT aims to fill these gap by bringing together the owners of the residual streams, the innovative technologies ánd the experts in possible feedstock-process combinations from physical and thermodynamic perspectives. Also, a joint development program will be set-up to accelerate the developments and solve both technical and non-technical hurdles.

For questions please contact Annita Westenbroek, coordinator of the Building blocks from waste program.

This program is always open for new ideas, suggestions and partners to start new innovation or coordination and support actions. For more information contact the program director or program support.
