Recycling of phosphoric acid

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.

Opportunities in emerging markets

The Styria based company Christof Industries has recently developed a user-friendly device, called SinTon, for the sterilisation of medical waste. The use of disposable products daily generates a high level of infectious residues, which must be disposed of in a cumbersome manner. Using SinTon, a combination of saturated steam and microwave energy completely eliminates the risk of germs so that medical waste can be disposed of with household waste. 25 of these Styrian high-tech devices have now been exported to Laos. This is a real revolution for the country in Southeast Asia, as medical waste in developing countries is usually disposed of in the untreated state together with household waste. This can lead to infectious diseases being transmitted to humans by animals. More →




Sustainable remediation of wastewater treatment systems

An interdisciplinary group of researchers from Graz University of Technology and the University of Graz developed a new material for reducing biogenic sulphuric acid corrosion (BSC) in wastewater treatment systems. The corrosion is caused by microbiological processes and produces a strong smelling and highly toxic sulphuric acid, which damages the concrete of sewers and destroys it within a few years. By researching this process, new acid-resistant materials with an antibacterial surface have been developed. This innovative material enables sustainable remediation of damaged sewage systems and significantly extends their service life. More →
