Waste to Energy Product News
Further expansion to Cleveland facility proves UK is still Europe's most active market In Europe, a wide diversity of established waste treatment options can be found. A lot depends on the drivers, such as the tax on landfill, established by the British government. But still, there are a lot of other questions: What is the best way to achieve the diversion, recycling, and renewable energy targets? With all these aims is it fair to ask whether really all roads lead to Rome? Different technical solutions come and go. One constant in safe waste treatment is traditional Energy from Waste (EfW) but there is so much more to it. Decades of continuous development mean that the current generation of incinerators are an environmentally safe, sustainable way of energy recovery. Barges deliver waste to the Riverside facility in London A variety of EfW projects are currently built worldwide: an extension to the district heating net in Oslo, Norway, supported by an EfW plant or in the UK, currently the most active market in the EU, where several projects are built and completed in parallel. For example, there is the timely and on budget delivery of the Cleveland extension line 3 in May 2009, which was a new benchmark of delivery in the UK EfW market. Now, one and a half years later, construction on Cleveland 4&5 is expected shortly, where AE&E is proud to continue on its path of reliability. Another example is the AE&E turnkey Riverside project, close to London with its unique waste delivery by barges, with its commercial operation scheduled in 2011. Even on islands like Mallorca, with a strong dependency on tourism, AE&E technology ensures safe waste treatment. All these projects have something in common: they are proof that successful projects are paving the way for their successors. Whereas in the UK, planning is often the biggest hurdle, in other countries often landfill is still the cheaper option. Nevertheless, upcoming projects in the US like the two projects in Maryland, for which AE&E is selected technology provider, are signs that EfW is again on its way forward. It is time to join forces, to pull together on the way to a safe and sustainable future. We look forward to be your partner to ensure for future generations that our environment will be protected and energy security is provided.www.aee-group.com Inashco moves Advanced Dry Recovery technology into production to recover bottom ash Inashco, Incinerator Ash Company, offers a unique bottom ash recycling service to the municipal waste incineration industry, based on the best available technology to treat the fine bottom ash fraction and recover valuable metals down to 1mm. Ashes to ashes: incinerator slag can contain 10% ferrous Up until now, the waste incineration sector had no answer to realize the full potential of its major residual stream: incinerator ash. The slag typically contains 10% of ferrous and 3.5% of non-ferrous metals. With the Inashco technology, the slag can be further processed to recover these metals and to remove contaminants in order for it to be used as an aggregate for the construction sector. With conventional technologies, only a small amount of metal (>12mm) can be extracted. Inashco’s advantages are: No investment: To ease the decision making Inashco invests in the production, installation and commissioning of the ADR installation, as well as equipment such as extra conveyor belts and (an) eddy-current separator(s) More revenues due to increased metal sales: After installation of the ADR, Inascho guarantees the purchase of the 1-12 NF mm concentrate against a specific fee No risk for the existing process: The ADR installation can be used as an extension to your existing installation Cleaner mineral fraction: Due to the more efficient recovery of metals from bottom ash, the mineral fraction is cleaner. After a successful pilot period, Inashco took a scaled up version of its patented Advanced Dry Recovery installation into production in October 2010. This installation can process 425,000 tons of bottom ash per year. Due to the more efficient recovery of metals from bottom ash, the mineral fraction is cleaner.There is a huge potential of finding alternative markets for cleaner mineral fractions. Inashco mainly focuses on two sustainable options: Substitution of primary gravel with the course mineral fraction (+2mm) in concrete products manufacturing (e.g. pavement and bricks) Production of ‘cold’ cement with the fine mineral fraction (0-2mm). Recycling a 100% of your bottom ash has become a real option.www.inashco.com Standardkessel and Baumgarte celebrate their anniversary In 2010 both companies had a lot to celebrate because this year marks the 85th or 75th anniversary of their respective company foundations. Standardkessel and Baumgarte In 1935 August Baumgarte takes over the casting and steam boiler production from K. und Th. Möller in Bielefeld. Design, production and the installation of apparatus and steam boilers is systematically developed. Baumgarte is quickly able to build up its reputation as a quality leader with modern testing equipment and methods such as X-ray, strength testing and chemical laboratory analysis. In 1950 the company became Germany’s second licensee for the construction of corner-tube boilers and also for the construction of vibrating grates, for the combustion of hard coal. Baumgarte’s customers cover the oil, food and paper industries. Following that, in 1962 Baumgarte received its first order for the construction of a refuse boiler and over the subsequent years Baumgarte was able to continuously develop its competence in the construction of waste to energy plants and establish itself as a pioneer in the construction sector of tail-end boilers. The company history of Standardkessel developed largely in the same eventful way. In 1925, chief engineer August Fasel took the step to be independent and founded the company Standardkessel. Already back in the 1930s his sons Josef and Wilhelm take over the management of the company. Up to the 1980s Wilhelm Fasel directs the business without his brother. The first patents are then registered. Since production of the shell boiler is severely limited, Standardkessel focused on building water-tube boilers in the 1950s. The “Condorkessel” and “Portakessel” have since become an export success, with more than 20,000 units of the Condorkessel having been supplied all over the world right up into the 1980s. The 1970s oil crisis triggers a development offensive. Systems using stationary fluidised bed combustion for use with local fuel/coal are developed and built. The crisis in the German power plant industry forces Standardkessel to close down all the production facilities in Germany. The shell boiler and water tube boiler business areas are separated. and the latter is incorporated into another company, known today as Standardkessel GmbH. Another positive decision since the water tube boiler business is now developing very positively, in particular on the back of the boom in biomass and combined cycle technologies. Today Standardkessel and Baumgarte supply turnkey power-plants and power-plant component for industrial and municipal energy supply. 160 years of experience with the topics of thermal utilisation of a broad range of varied energy sources is the result of adding the knowledge of the one to the know-how of the other.www.baumgarte.com From Low Grade Coal to Waste: the development of the MARTIN reverse-acting gate The company was founded in Munich in 1925 as “Josef Martin Feuerungsbau”. The MARTIN reverse-acting grate, developed by the founder Josef Martin, was the basis for the company. This grate was utilised in more than 300 lines for the combustion of low grade coal in order to produce steam and electricity. MARTIN can supply components or turnkey plants At the end of the 1950’s, the reverse-acting grate had its breakthrough for the thermal treatment of municipal solid waste. MARTIN GmbH für Umwelt- und Energietechnik as the successor operating company to Josef Martin Feuerungsbau was registered with the authorities in Munich at the end of 1982. The environmentally friendly treatment of residual waste from households and industry, using the energy contained in the waste in the form of steam and/or electricity (Energy from Waste), is an integral part of sustainable waste management. Plants for thermal treatment of waste, based on grate incineration, have been built for more than 100 years. Modern waste management, especially in light of efforts to reduce greenhouse gas emissions, would not be possible without these plants. MARTIN is a family owned engineering company, designing and building Energy from Waste plants for more than 50 years, based on the MARTIN reverse-acting grate. This grate, originally developed for the combustion of low grade coal, has been adapted to the incineration of waste in the 1950’s. Since this time, MARTIN has developed and improved this system, thus adapting it to ever changing requirements. Low emissions to the atmosphere, high usage of the energy contained in the waste and recycling of the solid residues remaining are the most important demands to such plants today, besides lower investment and operating cost. MARTIN can supply components, grate/boiler lots or complete, turnkey plants. The company does not have its own manufacturing facilities, but relies for the key components on selected, proven suppliers with whom MARTIN has worked since many years. At the headquarters in Munich, MARTIN employs about 200 people, with the majority of them being engineers. Another approx. 15 people are employed in two daughter companies, in France and in Switzerland - these mainly deal with existing facilities, providing revision, maintenance, spare part supply and plant optimisation services. In 2002, MARTIN took over the horizontal grate (system W+E) and the reverse-acting grate SITY2000 from ALSTOM, thus further strengthening its market position. As of mid 2010, 711 combustion lines with MARTIN technology have been installed or are under construction. MARTIN has been closely cooperating for many decades with strong partner companies (Mitsubishi Heavy Industries, Ltd., CNIM, Covanta Energy), which design, construct and in some cases also operate Energy from Waste plants in their respective markets, using the MARTIN grate systems. This ensures worldwide application of MARTIN technology.www.martingmbh.de Babcock & Wilcox Vølund lands order on second generation multi-fuel plant The new facility in Landskrona, Sweden is part of a new generation of plants capable of burning a wide range of biomass and sorted waste fuels.

Viridor will supply the waste through a Waste Supply Agreement with the SPV.www.keppelseghers.com COWI: Sustainable lifecycle thinking in waste management Sustainable waste management has long been an unquestionable part of Northern Europe’s waste solutions. Landfill disposal of combustible wastes is banned; instead waste recovery plants designed by architects fit into the surrounding environment. Designed by architects to fit into the surrounding area COWI has been part of this positive development of sustainable and cost-effective waste solutions for more than 40 years in several countries worldwide. COWI is ready to introduce its sound experience in waste management to regions, where lifecycle thinking, as for instance in materials recycling and in energy from waste, is as yet a relatively new issue. Important experience is presently gained from large and ongoing waste management projects in Denmark, where integrated waste management centres in Greater Copenhagen will accommodate waste to energy plants, materials recovery facilities, biological treatment and community recycling centres – all serving more than one million people. The experience shows that recycling and waste to energy go hand in hand and mutually improves the environmental and climate performance of integrated waste management solutions. COWI is currently involved in the Dublin WtE Project in Ireland, acting as the “Client’s Representative” on behalf of Dublin City Council. The project is developed as a PPP-project, where the private partner will finance and build the plant to the Client’s specifications and subsequently operate it for several years under contract. COWI is also involved in Northern Europe, the Middle East/Gulf Region, Southern Africa, generating sustainable waste management solutions involving a wide spectrum of technologies integrating the schemes for collection of waste with its treatment, recycling and disposal. COWI provides a wide range of interdisciplinary consultancy services within the field of engineering, economics and environment to both public and private organisations.www.cowi.com REWIN Network: Knowledge exchange platform on Energy from Waste Founded in 2000, the PREWIN European Network has been operated by KEMA since 2010.
