Wastewater – a recyclable resource!

26.09.2012
European joint research project P-REX has started to foster phosphorus recovery systems

Wastewater is not simply waste. Besides a considerable amount of energy, the sludge produced during wastewater treatment contains also a number of vital nutrients such as phosphorus and nitrogen.

For this reason, it has been a longstanding tradition to use sewage sludge as agricultural fertiliser. This method however, is hotly debated in the meanwhile, since besides valuable nutrients, also heavy metals or organic trace substance may occur, which should not find their way into food chains.

As a consequence, nowadays mainly artificial fertiliser is used for agricultural purposes. In this context, a problem has arisen due to the fact that the added phosphorus, which is mined in the form of phosphate rock in only few regions worldwide, e.g. China or Morocco, is a finite resource. The commodity markets have reacted accordingly in recent years: In 2006, the markets valued 1 tonne of phosphate rock to around € 35. Since then, the phosphate prices have increased manifold, and continues to trend upward.

90% of the phosphate rock used in Europe is imported. Germany imports 120.000 tons of these plant nutrients in the form of mineral fertiliser per year.

At the same time, wastewaters contain around 70.000 tons of phosphorus which is not used in most cases. The targeted recycling of phosphorus from wastewater could cover up to 60% of the demand in Germany. Numerous methods have been developed in the frame of pilot projects, but none of them has allowed for a large scale implementation. According to Andreas Hartmann, Managing Director of Kompetenzzentrum Wasser Berlin, this is due to the fact that the research activities carried out so far have rather focused on phosphorus yield than on the practical feasibility of the methods applied.

The priorities are to be changed now. The European research initiative P-REX, which is coordinated by Kompetenzzentrum Wasser Berlin, is intended to assist with advancing the development of efficient technological solutions for recycling phosphorus from sewage sludge throughout Europe.

In close cooperation with partners from science, industry sectors and agricultural professionals, the best practice recycling methods will be evaluated. Besides different technical solutions, these methods explicitly include also the direct use of wastewater in agriculture. The project aims to increase the recycling rate of phosphorus from wastewater to 80 %. In addition to the evaluation of the phosphorus yield, systematic investigations will also be carried out on the fertilising effect of the recycling products. Furthermore, the market potential of the individual recycling schemes and recycling products will be analysed.

The project consortium comprises 15 partners from seven European countries, among then nine SMEs. The project has an overall budget of € 4.4 million covering a period of three years, and will be supported by the EU with € 2.9 million.

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
