Filtrabit

Heavy industrial processes produce not only emissions but also dust-containing gas streams, which are released into the air due to the difficulty of filtering them. In addition, it is often impossible to utilise the energy contained in hot gases because of the dust in the gas streams. If left unrecovered, these dust particles pollute the air, damage the environment and cause health risks to humans.

Based on an innovative dust separation technology, Filtrabit’s extraction system effectively purifies industrial gas streams, even in applications for which this process was previously difficult or even impossible. The recovered dust contains valuable raw materials, which can be used in industrial manufacturing processes, reducing the use of virgin materials. In the future, the solution’s potential to reduce emissions may be multiplied several times over through the utilisation of purified waste heat.

The Climate Fund’s investment decisions are guided by a set of criteria emphasising impact, against which every case applying for funding from the company is evaluated. Preconditions for funding include a credible plan for repayment of the investment, alignment with the six environmental objectives of the EU’s sustainable investment network, i.e. the “do no significant harm” principle, and that with Climate Fund’s investment the project will be realised earlier, on a larger scale or in the first place. When the preconditions are met, the final selection will be made based on impact criteria, such as emissions reduction potential.

Filtrabit’s current emissions reduction potential is based on the recovery and utilisation of coke dust as an alternative to using virgin raw materials. The estimated emissions reduction potential of one extraction unit is approximately 200 t CO2-eq per year. The company’s cumulative emissions reduction potential is estimated to be approximately 128 kt CO2-eq over a period of ten years. In the future, the recovery of heat from industrial processes and possibly carbon dioxide would dramatically increase the emissions reduction potential of the extraction technology.

The capital loan of up to EUR 4 million by the Finnish Climate Fund has been allocated to raise working capital for the manufacture of extraction devices. The capital loan includes a conversion right and emission reduction incentive. The funding is targeted at industrial applications with heavy pollution loads or at applications with significant potential for emissions reduction. The service model will enable the rapid roll-out and scalability of the new technology on the market. Other necessary funding will be provided by the company’s owners and other lenders.
