Recycling of phosphoric acid
12. April 2018
The Styrian plant manufacturer BDI has landed a contract in Germany to design a special plant for phosphorus recycling. The range of services provided by BDI includes the preparation of the engineering local authority approval documents, detailed engineering design and upscaling. The plant is scheduled to go into operation in 2020 and will recover 6,500 tonnes of ultra-pure phosphoric acid from around 20,000 tonnes of sewage sludge per annum. In Germany, phosphorus is a vital but scarce raw material, which currently must be imported. But with its own recycling plant, it has sufficient support from this project to meet the strategic requirements to recycle this raw material from wastewater starting in 2029 at the latest.
BDI receives the order to plan an innovative specialized plant
The Styrian plant engineering company BDI – BioEnergy International GmbH is working on a funded project to recover phosphorus together with the companies REMONDIS and HAMBURG WASSER
By planning this specific plant, the Austrian company BDI – BioEnergy International GmbH can prove once again its expertise according to the company’s slogan “from Waste to Value”. Working in this project, BDI is responsible for up scaling, preparing the documents for the engineering authorities and for engineering in detail. The plant should operate by 2020 recycling from 20,000 tons of sludge to 6,500 tons of pure phosphorus acid.
Germany has to import phosphorus, which is a very important but also very scarce raw material. Due to building a recycling plant, this project fundamentally supports the policies that this raw material has to be recycled from sewage water by 2029 at the latest.
“After a two-year pilot phase the Hamburg Phosphorrecyclinggesellschaft mbh was founded – it had already been initiated by HAMBURG WASSER and REMONDIS in 2015. The test run has proven the technical feasibility and profitability of this procedure. The REMONDIS TetraPhos®-procedure is the only known procedure on the market that can recover phosphorus in a profitable way. “– statement by REMONDIS in an official press release of 3rd April 2018.
Engineer Markus Dielacher, Managing Director at BDI: “We can contribute considerably to this project with our expertise in building plants that produce value from waste. Working together with REMONDIS and HAMBURG WASSER poses a new challenge for us. We can contribute with our know-how and technological skills to this new and very important field for the future.”
