  • Dear Readers!

    “I believe in horses. Automobiles are a passing phenomenon.” These are the words said to have been uttered by the German Kaiser, Wilhelm II, at the time when mobility was going through a radical change. No one can say for sure whether he really said this or not but it is a quote that is often used as an example of people badly misjudging the importance of an invention – and not just by futurologists. Today, mobility is once again undergoing a radical change. In some areas of the country, air quality has deteriorated so much that politicians, industrial businesses and consumers are being forced to rethink the way they act, in particular in large cities. The diesel scandal has simply further aggravated the situation. The first councils have begun banning old diesel cars from using the roads where air pollution is highest. At the same time, city planners are focusing almost entirely on creating living space and high quality office buildings. In contrast, tradespeople and commercial businesses, such as recycling firms, are gradually being pushed further and further outside the city. Their work though should continue to be quiet, free of dust and, wherever possible, without CO2 or NOX emissions.

    It’s definitely time to start thinking about possible alternatives. What could be better than using one of the country’s waste streams – i.e. organic waste – as a source of post-fossil fuel and, by doing so, enable waste collections to be carbon-neutral and practically free of fine particulate and NOX emissions? REMONDIS has begun a pilot project near Cologne to do just this and is currently testing six vehicles run on biogas.

    The recycling industry has a new market player: the Schwarz Group (Lidl), which has an annual turnover of EUR 96.7 billion (2017) – bigger than the whole of the German recycling sector put together. Earlier this year, the Schwarz Group’s subsidiary, Green Cycle, purchased Tönsmeier, the fifth-largest recycling company in Germany, acquiring a volume of sales three times bigger than all of the acquisitions made by REMONDIS in 2016 and 2017. Industry experts believe that the Schwarz Group will also enter Germany’s ‘Dual System’ market (kerbside collection of sales packaging) in the not too distant future.

    There is so much happening in the German recycling market at the moment – a market which, according to the “Status Report on the German Circular Economy”, has around 10,800 companies competing against each other. While none of the private sector firms has a monopoly in any area of the waste management and recycling industry, the trend towards councils renationalising waste services continues unabated leading to the creation of regional monopolies. As a result, the private sector’s share of the market is also slowly decreasing. At present, for example, its share of conventional waste collection services lies at around 50% of the overall market. As always, we hope you enjoy reading this latest issue of REMONDIS AKTUELL.

An award-winning system

The company, Hamburger Phosphorrecyclinggesellschaft mbh, was founded in March 2018 following a successful two-year pilot phase. Its job: to recover 7,000 tonnes of pure phosphoric acid from 20,000 tonnes of sewage sludge ash every year. The pilot business has already confirmed that this is both technically and economically practicable. The system being used in Hamburg to carry out this work is REMONDIS’ TetraPhos® process and it is not only the only economically practicable system currently available on the market, it has also been presented with the GreenTec Award.

Plant due to be commissioned in 2020

  • The large-scale facility is due to be commissioned in 2020 and will be run as a public private partnership, with HAMBURG WASSER owning a 60% and REMONDIS a 40% share. “By recovering phosphorus, the company is actively helping to conserve natural resources and reduce the impact humans have on the environment – phosphorus is a vital raw material and supplies are becoming increasingly scarce,” explained managing director, Roland Ruscheweyh.

Recovering phosphorus will soon be obligatory

Phosphate is an important ingredient in mineral fertiliser and the fact that it is becoming more and more difficult to mine is already having a negative effect on food production. And with the world’s population continuing to grow, it may become increasingly difficult to supply everyone with the food they need. Recovering phosphorus has provided one solution to this problem – especially for agricultural businesses in Germany who have found themselves facing massive restrictions since the ‘DüMV’ [Fertiliser Ordinance] came into force in 2017. Almost 100% of all phosphate used in Germany has to be imported from abroad. This status quo, however, must have changed by 2029 at the latest: the German government has stipulated that large sewage treatment plants must recover the phosphorus from their sewage sludge or sewage sludge ash from this date onwards.

Further information about the Fertiliser Ordinance and the positive impact of compost can be found in the article “Compost – protecting water, storing water & naturally fertilising soils”.

HAMBURG WASSER and REMONDIS are ahead of the others with their newly established phosphorus recovery business and are acting as a role model for many large German cities as far as carrying out research work in this area is concerned. Its research activities and innovative work are being supported by the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU) as well as by the BMU’s Environmental Innovation Programme.
