Sustainable Solutions for Italian Biochemical Plant
When Italian biochemical company Mater-Biotech, a subsidiary of Novamont, bought an existing facility and was refurbishing and expanding it, it looked to Fluence to design and implement multiple solutions for its water and wastewater treatment needs.
This case study shows how Fluence provided the company with an effective turnkey operation that includes water treatment, wastewater treatment, and waste-to-energy technologies in three treatment trains, all in only one year.
In today's world, businesses in all industries are focused on sustainability, even as they seek ways to operate efficiently, meet permitting regulations, and make a profit. The technologies chosen for this project reflect the customer’s reputation for innovation, while also addressing its desire to reduce costs and become more sustainable.
Part of Novamont's sustainability model is the regeneration of local areas, including giving new life to existing facilities. When the company decided to refurbish a factory in Adria, Italy, it contacted Fluence to design and construct a system that could produce primary water for manufacturing from local wells, and a wastewater treatment plant capable of treating the biomass remaining from its fermentation process.
To reduce the company's environmental footprint and disposal expenses, Fluence incorporated a third solution: Waste-to-energy was added to the plant's capabilities, reinforcing Mater-Biotech's pursuit of innovative, environmentally-friendly technologies.
Perhaps the greatest challenge was that the client needed to go from commission to completion in a very short time frame. The project was awarded in March 2015 and completed in August 2016.
The primary water system provides water for use inside the plant. The treatment process which involves removing methane from the well water was successfully tested for two months using a Fluence pilot plant before full scale implementation.
The wastewater treatment plant is a membrane bioreactor (MBR) plant, which processes high-organic-load effluent from the production plant, as well as the liquid digestate from the anaerobic reactor.
In addition to the MBR wastewater treatment stage, Fluence added a biodigester to treat sludge generated by the process.
The design was based on Fluence's waste-to-energy solutions for treating high chemical-oxygen-demand wastewater from animal slaughterhouses, and other industrial plants.
This stage uses a continuous stirred tank reactor (CSTR) anaerobic digester with a volume of 5,000 cubic meters. It's capable of treating wastewater with applied organic loads of between 5 and 6 kilograms of COD per cubic meter per day.
