Funding from Vinnova SEK 500 000
Project duration May 2014 - December 2014
Status Completed
Venture Challenge-Driven Innovation – Stage 1 initiation

Purpose and goal

- Relevant stakeholders are now linked to the project. - Market analysis of other markets and a commercializationplan is taking shape - The design of a pilot begins to be clear. - Deeper study is complete. - A consortium draft has begun. - Patent analysis is still ongoing, but a general idea of execution is ready The purpose and goal of the project UDI step 1 has thus achieved.

Results and expected effects

The results from step 1 indicates that we have good opportunities to carry out steps 2 and 3 within the UDI program. Thus can we come to a paradigm shift in the management of fly ash and flue gas condensate. The expected impact is that the process can be commercialized after demonstrated in pilot and deomnstration scale. This means in turn that waste incineration can continue to be an integral part of the energy system that Sweden has chosen. This can create growth for Sweden and the energy sector and also contribute to increased employment in those industries related to the energy sector.

Approach and implementation

A literature study on washing of fly ash have been executed by all parties in the project. Several laboratory experiments have been performed on a ´ash wash´ and purification of washing liquid. They were analyzed before and after treatment. The results so far are good. The ashes can be purified to the point that it can be treated as non-hazardous waste, and the the solvent stream can be split into two streams, one containg heavy metals and the other non-hazardous metals. The developed process enables a cost-effective way to handle these waste products.
