Redwave Expands Waste Processing Business with a New Subsidiary in Germany
First major projects in Finland, Scotland and China
REDWAVE, as a leading supplier of sensor-based sorting machines and turnkey material-sorting systems, has taken a decisive step to expand its business in the waste-processing sector by founding a new subsidiary, REDWAVE Waste GmbH. The new company is located in Wetzlar, Germany and was incorporated in 2015. It adds the important area of mechanical-biological waste treatment to REDWAVE's product portfolio. Also, REDWAVE Waste GmbH is now responsible for acquisition and management of all of REDWAVE's projects in the waste-processing sector worldwide.
The Division Waste within the REDWAVE group mainly provides waste-processing solutions, using automated mechanical sorting and processing technologies, for converting waste into secondary fuel and usable recycling fractions. REDWAVE provides complete processing lines as turnkey packages, but also offers individual machines and a comprehensive spectrum of related engineering and consulting services. Among the technologies offered is biodrying, which greatly improves the sortability especially of damp wastes with high organic content. This improves the quality of the processed materials and the commercial potential of the waste-derived fuels and recycling materials.
Another specialty are turnkey plants for environmentally friendly composting of organic waste, such as kitchen waste, waste food and increasingly, residual material from biogas fermentation plants. Special processing systems are needed to convert these materials to valuable compost: the waste must first be separated from contaminants such as plastics and metals, and then composted under controlled conditions. The necessary quality for sale as compost is then achieved by a final phase of sieving and visual inspection steps.
The team of REDWAVE Waste GmbH consists of 20 experts in relevant fields. They represent more than 20 years of experience in design, construction and operation of mechanical-biological waste treatment plants from their previous work in the companies Waste Tec GmbH and Herhof Umwelttechnik GmbH, which have been amalgamated into the new company. The employees' profound expertise in waste processing technology and the practical experience of building many plants in Germany and abroad make them excellently qualified to lead all of REDWAVE's activities in the waste sector.
CEO of REDWAVE Waste GmbH Silvia Schweiger-Fuchs sums up the strategy as follows: “By combining the two major areas of technology – sensor-based sorting on the one hand and classical mechanical-biological treatment on the other – we have become one of only a few suppliers on the market who are able to offer clients complete solutions designed individually to meet their needs. With the expertise of our group and the range of technologies we can deploy, we can further improve the recovery of valuable materials from waste and can respond to the increasing global demand for recycling-oriented processing concepts.”
“Working with our new colleagues from Wetzlar is going smoothly, and including them in the REDWAVE group has been a big step forward that opens up new developments and growth. Now the first successful projects are confirming how good this decision was”, reports CEO Silvia Schweiger-Fuchs.
For example, in the past year REDWAVE was able to acquire two large projects in Finland and a project in Scotland for its newly created Division Waste.
The project in Finland, which REDWAVE was awarded in July of last year, is a combined plant for sorting the light fraction of household waste and waste packaging, and for mechanical processing of household waste to fuel. The two plants together have a capacity of 175,000 t per year. Construction of both plants began in December 2015 and will begin operation in summer of 2016.
In Scotland, REDWAVE is supplying the fuel storage and feed technology for a gasification plant. This project is currently in the design phase; the whole plant is planned to go into operation in summer of 2017.
The project in China represents a new kind of process in terms of plant size and MBT technology in China. It is a mechanical-biological waste processing plant with an annual capacity of 270,000 t, in which household waste is first dried biologically and then processed mechanically. The drying of the household waste, which is very wet in China, allows usable materials such as ferrous and non-ferrous metals to be recovered and impurities like glass and stones to be separated in the mechanical process. All the combustible components such as plastics, wood, paper, and organic materials are converted into a fuel that is used in an existing fluidized bed reactor for efficient power and heat generation. The mechanical-biological processing plant will be operated fully automatically.
The plant will be built in eastern China, north of Shanghai; it is the first of its kind in China.
“This project is a milestone in the development of the Chinese market for our company”, says CEO Andreas Puchelt. “The approach of sorting the waste before incineration, in order to recover recyclable materials and also to make energy generation from waste more efficient is new in China and has huge potential for us”, he says. He concludes: “The environmental standards in China will be raised relentlessly, like in Europe. To keep up, Chinese companies have to invest in new technologies. Our approach of offering the latest processing and sorting technology from a single supplier has paid off again as it did in other projects. We see this project as our entry into a very dynamically growing market, not only in China but in all of Asia”.
