Waste-to-Resources 2017 Ways for increased material recycling of material flows from MBTMatthias Kühle-Weidemeier
By implementing modern thermal and non-thermal waste treatment technologies, waste management hast made a big leap forward. In the last two decades, Central Europe has been the motor of the development. The first decade of this century has been a period of development and installation of new processes in numerous locations. This was followed by nearly a decade of minor progress. This article will analyse the current situation and show how higher recycling rates even from mixed and residual waste can be achieved.

Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben Solid Recovered Fuel – Optimization of Plants in the Polish Economic RealityArtur GradziÅ„ski
Waste management and district heating systems, especially in scope of smaller facilities, require a thorough modernization. In addition, the existing model of these systems, especially for small and medium-territorial units, is not able to meet new requirements of the EU policy in the field of resources and energy efficiency. It is therefore necessary to seek for the new model which quality will be closer to the requirements of the overall strategy of the European Commission, whose key elements includes the impact of the project on the social prosperity and the preservation of the principles of sustainable development.
TK Verlag - Fachverlag für Kreislaufwirtschaft Refuse Derived Fuel – A European Market Heading for OvercapacityMike Brown
During the last five years, the residual waste market has been transformed from one whose geography was largely defined by a country’s borders to one that has become truly European in nature. Increasing, and now significant, tonnages of refuse derived fuel (RDF) and solid recovered fuel (SRF) are moving across national boundaries. In the UK, for example, the export of RDF and SRF has grown from 250,000 tonnes per annum (tpa) in 2011 to 3.4 million tpa in 2015.

TK Verlag - Fachverlag für Kreislaufwirtschaft Complex Approach towards the Assessment of Waste-to-Energy Plants’ Future PotentialDr. Martin Pavlas, Ondrej Putna, Jiri Kropác, Professor Dr.-Ing. habil. Dr. h. c. Petr Stehlik
There is a fierce debate ongoing about future recycling targets for municipal solid waste (MSW) at the European level. The old linear concept of waste management is being changed into a circular economy. Since the separation yield and post-recycling MSW (later on residual solid waste, RSW) production have an opposite relationship, assuming the constant production of particular components (paper, plastics etc.), lower RSW rates are also expected. This is having a negative effect on Waste-to-energy (WtE); especially in terms of its future optimum capacity in particular countries.
TK Verlag - Fachverlag für Kreislaufwirtschaft Manufacturing of Solid Recovered Fuels (SRF) for Energy Recovery ProcessesDipl.-Ing. Dr. mont. Renato Sarc, Univ. Prof. Dr.-Ing. Karl E. Lorber, Univ.-Prof. DI Dr. mont. Roland Pomberger
This contribution describes manufacturing processes and quality of three types of
Solid Recovered Fuels – i.e. SRF low quality, SRF medium quality and SRF premium
quality – that are used in energy recovery plants. In total, two case studies are reported.
First case study is about the external processing and confectioning of non-hazardous
household, industrial and commercial mixed wastes as well as the internal treatment
and homogenisation of various waste fractions at the incineration plant for production
of SRF low quality that is utilized in a Waste to Energy (WtE) stationary Fluidized Bed
Incinerator. In the second case study, production of SRF medium quality and SRF premium
quality that are used for substitution of primary fuels like coal and petrol coke
in the cement kiln is described. Finally, data on SRF quality of all three investigated
waste types will be summarized and discussed.
TK Verlag - Fachverlag für Kreislaufwirtschaft Modelling of Solid Recovered Fuel (SRF) Properties Based on Material Composition – Chloride QualityInnes Deans, Ioannis Dimas, Costas Velis
Producing solid recovered fuels (SRF) is a well-established route for recovering energy resources from municipal solid waste (household and/or commercial). Chloride content critically impacts the quality of SRF. It directly influences operation of thermal processes, having deleterious effects through the high temperature corrosion of the boilers and through demands placed on the flue gas treatment (FGT) system, which could impact emissions control. Whereas design and specification of process plant can mitigate the technical issues associated with the presence of chloride experienced during thermal treatment, processing such fuels is associated with increased capital, operating and maintenance costs. This, at best, restricts the uptake/use of SRF or increases the cost of its treatment towards achieving a reduced chloride content.

Energy Works Hull (the Project) is a milestone project for the UK’s waste and renewable energy sector. It will be one of the largest gasification facilities receiving MSW in the UK, indeed in Europe. It is one of the first advanced conversion technology Projects to receive its renewable electricity subsidies through a Contract for Difference, the mechanism by which the UK Government determined to move from Renewable Obligation Certificates following its Electricity Market Reform process. It also plays a significant part of the urban regeneration of the City of Hull. The level of community engagement and benefit has resulted in the project receiving a GBP19.9M grant from the European Union’s Regional Development Fund.
TK Verlag - Fachverlag für Kreislaufwirtschaft Use of a Fabric Filter for the Sorption – What Has to be Considered? – Experiences and Solutions –Dipl.-Ing. Rüdiger Margraf
In almost all flue gas cleaning systems installed at WtE-plants, the fabric filters are central components. A good example for this is the conditioned dry sorption process which is currently preferentially used in Europe. Within the filter not only the particles and the particulate heavy metals are separated from the gas flow, but also all reaction products resulting from the separation of gaseous pollutants such as HF, HCl, SOx, heavy metals and in this respect particularly Hg as well as PCDD/PCDF. In addition to this the fabric filter constitutes an excellent reaction chamber with high additive powder density in the filter cake.
TK Verlag - Fachverlag für Kreislaufwirtschaft Enhancing of the Energy Efficiency of an Existing Waste Incineration Plant by Retrofitting with a District Heating NetworkProf. Dr.-Ing. Wolfgang Rommel, Thorsten Freudenberger, Dipl.-Ing. (FH) Markus Hertel, Thomas Moritz
The German Cycle Economy Act (Kreislaufwirtschaftsgesetz KrWG) and discussions on the turn of local energy policies led to intensive examination of options for optimising utilisation of heat produced by the waste incineration plant (MKW) in Weißenhorn. This has been carried out by the waste management firm(Abfallwirtschaftsbetrieb – AWB) of the district of Neu-Ulm over a long period of time. This was also prompted by knowledge that utilisation of already generated energy in the form of combined heat and power generation (CHP) is one of the most efficient ways of achieving climate protection targets. This results from considering which courses of action are available for climate protection.
TK Verlag - Fachverlag für Kreislaufwirtschaft International Experience of Risks Sharing between Public and Private Entities in Energy-from-Waste Plants ConstructionChristophe Cord´Homme
Imagine that you are the mayor of a city named Metropolis and are in Charge of School logistics. Before doing so, you might have to ask yourself a few essential questions. What kind of transportation will you provide? Who will it benefit: students, staff or both? Where will the service be provided? When will it be provided: in the evening, morning? And finally, how much will it cost? All these essential questions need to be answered before starting to implement this project and to buy your buses. By doing so, planning, financing, building and operating the chosen mean of Transportation will become an easier task. After that, your political decisions will direct the choice of implication of private sector on the different aspects of your project.
TK Verlag - Fachverlag für Kreislaufwirtschaft The Added Value of the Balance Method for Waste-to-Energy Operators and National AuthoritiesDipl.-Ing. Dr. Johann Fellner, Professor Dipl.-Ing. Dr. Helmut Rechberger, Therese Schwarzböck
Different directives of the European Union may require operators of Waste to Energy WTE plants to monitor the composition of their waste feed with respect to the Content of biomass and fossil organic matter. The mass fractions of both materials are not only of relevance for the amount of fossil and thus climate relevant CO2 emissions of the plant, but also for the ratio of renewable energy generated, as biomass in wastes is considered as renewable energy source.
TK Verlag - Fachverlag für Kreislaufwirtschaft Application of Modified NiCrMo Alloy Systems for Boiler Tube Surface Protection in Waste-to-Energy EnvironmentsIain Hall, Kwang Han, Dr. Tri Shrestha
Internationally, Waste to Energy and Incineration markets continue to grow in capacity as fossil fueled facilities decline and nuclear generation is curtailed. With this comes a greater need to burn more corrosive materials combust at higher temperatures and extract more energy. The reliability burden that this places on operators of plants is re-opening opportunities for thermal spray solutions as a cost effective solution for boiler tube protection. Where maintenance costs, opportunity costs and access restrictions may preclude alternative in-situ technologies, thermal spray technology may fill a gap in providing new reliable and flexible process and materials technologies for both mid- and long-term protection of water wall and superheater tubes. While historically thermal spray coating solutions have had a spotty record in waste to energy environments, advances in both process and materials technology specifically for WTE environments is such that coating performance now approaches the performance of high alloy wrought materials. This is verified through accurate laboratory modeling and scale tests and trials conducted by OEM’s and plants.
TK Verlag - Fachverlag für Kreislaufwirtschaft Development of Waste-to-Energy ProjectsTrimurti Irzan, Martina de Giovanni, Lukas Schwank
The first objective of waste management must always be to protect society and the health of individuals from harmful substances contained in the waste. Along the various methods around the globe with which waste has been treated the waste pyramid or waste management hierarchy has become widely accepted as the governing principle for waste management in modern societies. These principles have also been integrated in the European waste framework directive 2008/98/EC. At the bottom of the pyramid lays disposal of waste, meaning it is the least favourable option to treat a primary waste. However this does not mean implementing the waste pyramid prohibits disposal. It merely means that before disposal all other meaningful options are exhausted, and the quantity has been minimized.
TK Verlag - Fachverlag für Kreislaufwirtschaft Significance of and Challenges for Flue Gas Treatment Systems in Waste IncinerationProfessor Dr.-Ing. Rudi Karpf, Andreas Wiedl
Flue gas cleaning downstream of waste incineration plants had its origins in the increased construction and deployment of such plants to counter rising air pollution in the nineteen-sixties. Back then, the ever-growing burden on the environment caused lawmakers to start enacting emission limits for air pollution control. An unceasing series of environmental scandals and increasingly better analytical methods and measuring instrumentation led to a constant reduction of the emission limits and, consequently, to ongoing adjustment and further development of the necessary process stages in flue gas cleaning. As a result, today minimum emissions can be reached even under the challenging condition of deployment of a very inhomogeneous fuel (waste) and, hence, waste incineration today is no longer a key contributor to air pollution. Today, the need for flue gas cleaning is not called into doubt anymore and has long become a matter of course in the industry and in society at large. Apart from ensuring efficient elimination of noxious gases, the focus of today’s further developments is on issues such as energy efficiency, minimization of input materials and recovery and recycling of by-products from flue gas cleaning as valuable raw materials. These issues are also deemed to be key challenges, especially when it comes to selecting sites for new plants in such a manner that potential synergies can be exploited. Such aspects will also have to be considered in the plans for the predicted mega-cities of the future.

TK Verlag - Fachverlag für Kreislaufwirtschaft Initial Operating Experience with the New Polish Waste-to-Energy PlantsProf. Ph. D., Eur. Ing. (Dr.-Ing. habil.) Tadeusz Pajak, MichaÅ‚ Jurczyk
Waste-to-Energy plants are an integral part of modern municipal Waste Management Systems. Today recycling and energy recovery from waste are the only methods of dealing with municipal waste. This is demonstrated by Waste Management Systems in countries such as Germany, Sweden, the Netherlands, Belgium, Denmark and Austria, where the municipal waste management is limited solely to recycling and energy recovery from waste. The currently discussed concept of the latest circular economy package can hardly change anything in this matter. Poland, as one of the leaders among the new EU member states (since 2004), has still a lot to do within the scope of recycling and waste-to-energy.
