Recycling Services
Through our SOLVAir® Residual Sodium Chemicals (RSC) recycling solution, we offer our customers the possibility to handle the recycling of the residue generated by their flue gas treatment systems. To do this, SOLVAir® has developed and patented an original technology that allows the production of purified sodium brine from flue gas treatment residue in order to replace the natural brine used in soda ash production plants. Our operations Solval® in Italy and Resolest® in France have successfully industrialized this technology since 1998. None of our competitors can offer this service at the moment.
A service adapted to all our customers
This offer could work for all our customers in search of solutions to decrease their environmental footprint and increase their regulatory compliance, from waste-to-energy operators to industrial clients as well as the marine industry.
Whatever the industry, recycling replaces the extraction of virgin raw materials with chemical processes and reduces the amount of residue to be landfilled by a factor of 10 or more.
The brine recycling process
The SOLVAir® RSC Recycling process yields a brine whose contents can be recycled. The residue is dissolved in water at a controlled PH, with additives, and filtered in order to eliminate residual organic matter and any remaining traces of heavy metals.
The purified brine is then re-used in the sodium carbonate manufacturing process. The recycling operations are conducted at specialized facilities located close to sodium carbonate production centers.
Promoting the circular economy
Thanks to this process, natural resources are saved and landfilling following the incineration of flue gas residues is avoided. What’s more, recycling sodium chemicals residue is in line with circular economy policies.
A unique, environmentally sound service
SOLVAir® is the only player offering the recycling of flue gas treatment residue. We combine the transport of sodium sorbent with that of the residue by using the same trucks, thereby reducing pollution and traffic congestion. Lastly, the recycling process doesn’t generate any emissions in the air or effluents, making it an environmentally sound process.
- Nearly 2 million tons of brine recycled so far
- Successful operation for over 20 years
