  • Dear Readers!

    In Germany super election year 2017 is well underway. The Saarland election has already taken place, with Schleswig-Holstein and the most populous of the German Länder, North Rhine-Westphalia, set to follow in May. General elections for the Bundestag will then be taking place in September. In these times of populism and fake news, this election will play a pivotal role. Germany has the strongest economy and largest population in Europe. The outcome of the election will have repercussions for all of Europe and influence economic and political relations with other countries around the world. In view of the dimensions involved, a key topic unfortunately often takes back seat: recycling and its importance to climate and environmental policy. We wanted to size things up accurately and enquired with all the major political party groups about their platforms concerning environmental policy in the upcoming legislative period and beyond. You will find a summary of the responses in this issue’s feature article and the complete responses online at remondis-aktuell.de. Whether elections turn out to be good for the climate and the environment in general and our growth sector in particular will ultimately be decided by hopefully well informed, active citizens.

    Some legislative bills have been initiated shortly before the elections – for example, the new Commercial Waste Regulation (Gewerbeabfallverordnung). It will involve important changes that have a major impact on our commercial customers when the new regulation goes into effect on 1 August 2017 at the latest. Under the new version, companies producing waste in connection with housing construction will be obligated to separately collect the waste items of paper, cardboard and pasteboard with the exception of hygienic paper, glass, plastics, metals, wood, textiles, organic waste and additional commercial and industrial waste already where it comes about, i.e. at companies themselves. The same goes for construction and demolition waste, which is already to be separated at the building site into the various waste categories such as glass, plastics, metals, wood, insulation material, bituminous mixtures, building material based on gypsum, concrete, bricks, tiles and ceramics. This is no doubt good news for improved recovery of raw materials, but it also means greater expenses for customers, who ­REMONDIS will support professionally as accustomed with practicable services in line with laws and regulations. 

    And how do things stand at present when it comes to refugee policy? The number of new persons seeking asylum arriving in Germany has dropped significantly. The biggest challenge now is to successfully integrate these people in our society and the German world of work. ­REMONDIS is taking on this challenge, hiring young people as well as persons with work experience in various fields who have lost their home as a result of war, famine and displacement and now want to venture a new beginning in their adopted country of Germany. A real win-win situation, as a successful start to a vocational career is the best contribution that can be made to a society living together in prosperity and peace. Here as well, ­REMONDIS meets its responsibility to society as a whole, acting in the spirt of its own slogan: working for the future!

New coatings required

  • The service life and operating efficiency of industrial machines and equipment are very closely entwined. Professional maintenance work not only considerably extends the length of time they can be used but also ensures operations run smoothly. This is also true for a tank farm at the Lippe Plant which is currently being re-coated by XERVON Oberflächentechnik.

  • Tanks need to be completely overhauled

    REMONDIS processes and recycles alkaline solutions at its Lippe Plant, the largest industrial recycling centre in Europe. To be able to do this, it operates a tank farm that has the capacity to store up to 35,000 cubic metres. The majority of the tanks (each twelve metres high) are indoors and have been around for much longer than the Lippe Plant’s recycling operations. They were installed when the site was still being used to produce aluminium which means the tanks must have been in operation for at least 80 years now.

    XERVON Oberflächentechnik is well known for its high quality work and its exemplary levels of safety and performance

    XERVON Oberflächentechnik is currently overhauling the tanks so that they can continue to be used for many years into the future: the interior coatings are being completely renewed in many of these large-scale tanks as are some of the exterior coatings. Work that is well worth its while as these tanks have solid steel jackets and secure rivets and were obviously built to last.

Collaboration within the Group

  • One by one, the individual tanks are being taken out of service so that they can be overhauled using a multi-stage process. The first task is to remove the deposits that have gradually built up over the decades from the interior walls of the tanks. REMONDIS’ subsidiary, BUCHEN, is responsible for this work – dislodging all of the coarse deposits using their high pressure water jetting equipment (around 1,000 bar). XERVON Oberflächentechnik then moves in afterwards to get rid of any remaining substances once their colleagues from XERVON’s scaffolding division have erected the work platforms so they can access the tanks.

    Meticulous preparation work is vital if the best conditions are to be created for the subsequent coating. XERVON Oberflächentechnik needs three individual stages to coat the tank interiors and provide them with a 750 Mµ (i.e. 0.75 millimetres) protective layer, which has been specially selected to suit the alkaline solutions that will be stored in the tanks afterwards. Measurements are taken throughout the process to ensure the three-layered coating has the right thickness.

    • Before: the tanks at the chemicals processing plant in Lünen were beginning to show their age – the chemicals and alkaline solutions had certainly left their mark

    • After: XERVON Oberflächentechnik coated the twelve-metre tanks after REMONDIS’ subsidiary, BUCHEN, had removed all the deposits from the surface

Specialist knowledge combined with excellent workmanship

  • “The biggest challenge when dealing with tanks is to ensure you find the right coating material and application system that best suit the medium being stored,” explained Frank Dörnemann, managing director of XERVON Oberflächentechnik. The requirements are as diverse as they are complex. The substances being stored in a tank may, for example, be corrosive or abrasive and all these factors must be added to the equation when selecting the right coating. What’s more, other variables such as safety issues, staff and guarantees need to be taken into account for each individual project.

    Using the right coating not only ensures structures remain fit for purpose, it also considerably extends their service life

    XERVON Oberflächentechnik specialises in all automated and manual coating processes and systems. In addition, the company also performs specialist coating work that has been adapted to meet particular application requirements, including hot spray coating techniques. Besides working on tanks, it also coats steel structures, floors, machinery and cranes, protects industrial plants against corrosion and carries out conventional painting work. Many of these tasks are performed in the company’s own blasting and coating facilities which are equipped with state-of-the-art technology. XERVON Oberflächentechnik often has permanent teams working on site at their customers – such as at large industrial plants and chemical parks – so that they are always on hand to carry out any work needed.

Reorganisation of the surface technology division

  • “In-depth know-how, highly qualified staff and specialist technology are our particular strong points,” Frank Dörnemann continued. This division was, therefore, reorganised at the end of last year to enable the business to further strengthen its position on the market: on 01 December 2016, XERVON turned its surface technology division into a company in its own right, XERVON Oberflächentechnik GmbH, by way of an asset deal. The new company’s head office is in the German city of Bottrop. This move reflects XERVON’s goal to turn its individual business divisions into specialist companies. Frank Dörnemann commented: “By doing so, we can pool together our activities and grow our services to meet the exact requirements of our customers.”

    • Frank Dörnemann was appointed managing director of the newly founded company, XERVON Oberflächentechnik GmbH, at the end of last year
