Project description
Creating a closed loop for wastewater processing with recycled CO2
The EU goal of sustainability and emission reduction across its sectors and industries requires both resource efficiency and efficient recycling of waste. Waste and wastewater treatment currently emit large amounts of CO2. The EU-funded WaterProof project will tackle this issue by developing a clean water cycle loop that uses CO2 and reduces greenhouse gas emissions. To do this, it will use the CO2 from the waste incineration and wastewater treatment in an electrochemical process to make formic acid for consumer products and oxidants that are useful during the decontamination process.
Objective
The WaterProof project proposes a resource efficient solution convert CO2 emissions from waste(water) processing into green consumer products. At the heart of the WaterProof concept is an electrochemical process that converts CO2, originating from waste incineration and wastewater processing, to produce formic acid. This reaction is paired with the generation of high-energy oxidants, which are used to remove persistent contaminants from wastewater thereby contributing to a clean water cycle with zero-waste. The energy to run the electrochemical process is provided by waste incineration facility. The formic acid is a feedstock for the production of Acidic Deep Eutectic Solvents (ADES). These ADES are used to extract precious metals from water treatment sludge and incinerator ash. Additionally, the formic acid is used for fish leather tanning to sustainably produce fish leather and will be tested in consumer cleaning products. The WaterProof technology results in a GHG reduction based on CO2 utilization, replacement of fossil feedstock and by industrial electrification. In the WaterProof project, a TRL 6 plant is constructed, including innovative downstream processing. The conversion of CO2 from wastewater treatment and the CO2 captured at a waste incinerator is demonstrated in two consecutive campaigns. To maximize impact of the WaterProof technology, life-cycle assessments and a full business case analysis are initiated in the early stage of the project to provide targets for technology development. A marketing and deployment strategy is developed to ensure social acceptance of the WaterProof technology. Besides the reduction of GHG emissions, WaterProof will have societal impact by, creating awareness trough interaction with policy makers and civil society and the creation of new jobs in innovative fields. By targeting an industry as essential as waste(water) treatment, WaterProof aims to create a concept that can impact society and climate on a big scale.
