  • Dear Readers!

    Even after just a few months, 2019 is already panning out to be a year full of uncertainty. We are all having to face a variety of challenges. With many of these linked to climate change and the environment, they are automatically affecting the environmental services sector as well. The impact of climate change could be felt all around the world last year with countries being struck by floods, forest fires and drought – and experts are expecting more of the same this year. Both industrial and political decision-makers and consumers across the globe are well aware that urgent measures need to be taken to reduce greenhouse gas emissions – something that has been further highlighted by the young Swedish environmental activist, Greta Thunberg, who has inspired schoolchildren to take to the streets on Fridays to get adults to finally tackle this problem. This will be a mammoth task as it involves nothing less than halting the loss of biodiversity and ensuring there are sufficient supplies of natural resources for future generations. And this is precisely what REMONDIS does by recovering high quality raw materials from waste. Indeed, there is no other individual measure that is so successful at cutting greenhouse gas emissions and conserving natural resources. And this is why we see it as our task to extend the reach of our services and pass on our know-how to others – especially to other countries – to promote resource-friendly recycling activities.

    Our industry is currently undergoing a technological change that will alter the way many things are done. As the world becomes ever more digital, it is inevitable that this technology will have an impact on our everyday lives as well as on the way we do business. The spread of digitisation, however, is creating its own new set of challenges. The political environment in many regions around the world is also changing which could hamper our cross-border efforts to promote sustainable development. This, of course, also includes the uncertainty surrounding Brexit and the growing tensions between the so-called superpowers. We need the support of our politicians so that we can make the world that little bit more sustainable – whether it be the implementation of a Europe-wide landfill ban or the creation of an Ecodesign Directive that takes raw material efficiency into account as well as energy efficiency. All in all, the upcoming European Elections will be an important political milestone for Europe.

    REMONDIS is doing its utmost to turn these challenges into opportunities and to navigate through these stormy seas safely. We are marking out the way for sustainable success by investing in technology and growing our portfolio.

Technology leader now a part of the REMONDIS Group

Walter Tecyard GmbH & Co. KG became part of the REMONDIS Group in October 2018 when REMONDIS Aqua Industrie GmbH & Co. KG purchased a majority share in this young company. Walter Tecyard, a technology firm based in Kiel in the north of Germany, is leading the way when it comes to digitising water management, making it a perfect fit for REMONDIS Aqua’s business.

Permanent monitoring means greater security

Walter Tecyard provides smart services with its sensor technology and biomonitoring innovations. It has developed a series of systems that work together perfectly to record and process data and so ensure that municipal and industrial networks operate smoothly. Drinking water networks are monitored regularly and protected from unauthorised access. It is not, however, always possible to permanently monitor these networks or to carry out checks beyond the normal parameters. These gaps can now be filled by the SensaGuard system. This biomonitoring system uses the freshwater shrimp, Gammarus pulex, as an indicator organism to detect even the smallest change in the quality of the water. “Freshwater shrimps live in clean, oxygen-rich waters and react immediately to the slightest physical change or to the presence of pollutants,” explained Dr Axel Leybold, managing director of Walter Tecyard.

Thanks to Walter Tecyard, local authorities can make sure their town and the services they offer their residents are even smarter.

As a result, raw water and drinking water can be monitored online – permanently and transparently – making it possible for the system operators to respond more quickly to incidents. The challenge of sensor technology is to be able to offer an integral system that enables all the different pieces of information to be recorded and merged together.

Installation in line with the ‘plug and play’ principle

Walter Tecyard already uses tried and tested sensors and gateways as well as data processing and back end solutions. “There are plenty of companies supplying the individual components. What we – and just a handful of other firms do – is to unite all these modules to provide one meaningful system,” commented Benedikt Winkelmann, managing director of Walter Tecyard. The sensors can work for long periods of time without requiring an external energy supply and the data can be transmitted above ground or from the network of pipes and shafts.

SensaGuard fills an important gap in drinking water monitoring systems and can detect even the slightest change in the quality of the water.

The system is installed in line with the ‘plug and play’ principle. The data is then evaluated and made available online on a customised dashboard. The first projects have already begun in Kiel, Copenhagen and Hamburg. This is a simple and safe way for local authorities to create an intelligent network within their infrastructure and ensure they have a secure supply of water. Walter Tecyard and REMONDIS are, therefore, helping smooth the way towards setting up smart cities.
