CREATING CIRCULAR VALUE CHAINs with superfine fly ASH
Globally, >150 million tonnes of landfilled fly ash contain valuable superfine fly ash fractions
Superfine fly ash is very difficult to separate. Value Ash has the technology to extract the ~20% superfine fractions efficiently and at low cost. Currently about 150 million tonnes fly ash that are landfilled contain such valuable fractions that could be separated .
Superfine fly ash is a resource for low cost superstrong concretes and geopolymers
To make ultra high strength concrete it was needed to use superfine silica fumes for 5 to 15% of the binder content. Silica fumes are expensive, in the order of 600 to 1000 US$ per ton. Only 5 million tonnes silica fumes are produced annually globally. Superfine fly ash <10 micron increases the packing effect. It has about 85% of effects of silica fumes at 1/3 of the costs. Superfine fly ash allows to create much stronger and more durable concrete It is also more reactive to create better geopolymers.
Value Ash patented separation technology
Value Ash Technologies has developed and patented a unique fly ash separation technology in partnership with VITO, a leading Belgian research organization. The technology extracts superfine ash particles, which can then be transformed into ultra high strength concrete and novel geopolymer applications. Value Ash offers:
• Industrial separation technology for superfine fly ash
• Innovative value chains for high strength concrete and geopolymers
About 30 million tons superfine fly ash could be made available globally with Value Ash patented technology.
Transforming superfine fly ash into economic and development empowerment
Value Ash offers cost-effective, durable product streams that address the SDG and national development goals of many countries:
· Stronger and more durable concrete products such as retaining walls
· Agriculture, water storage, and infrastructural solutions using high strength concrete and geopolymer applications
· Social and urban slum housing solutions
· Innovative ultrathin lost formwork using superfine fly ash
Value Ash collaborates with Belgian and European industrial, university and research partners to provide these solutions.

We are proud to work with our South African partner Cenospheres South Africa Ltd to develop our first JV in South Africa
Combining several European innovation and circular value chains to increase SDG impact
Value Ash transforms its innovative solutions into industrial production using local resources and empowering local partners. We combine our circular added value chain of fly ash with other European innovation and circular value chains such as of steel slags, biogas and basalt. This will help solve the SDG locally and globally by combining raw materials streams.
Value Ash Technologies has developed its technology with funding and support of the EIT raw materials programme of the EU Horizon program.
