The improvement of recycling and reuse of waste is becoming more and more important and it is generally preferred compared to waste incineration. In fact, the incineration of waste is often considered the last alternative when recycling of a certain waste fraction is technically not possible or there is simply no market for the corresponding fraction of the waste. But instead of considering waste incineration as being contradictory to recycling, it may also be considered as an alternative way to achieve higher recycling rates. The main goal of waste to energy is the use of the chemical energy contained in the carbon and drogen, and transfer this into thermal energy. But all other elements contained in the waste will of course also be found in the various residue streams leaving the plant. For these residue streams there are possibilities for further treatment, enabling Separation of certain elements, improvement of the quality of a residue stream to allow re-use on the market or even potential for the preparation of a new product.
Apart from increasing the pressure to reuse and recycle, either from the public, or simply due to rising market prices for certain elements, there are also other possible reasons: So far waste incineration is used widespread in industrial countries with clear guidelines for treatment and disposal of the residues such as slag/bottom ash or flue gas treatment residues. These proven ways for disposal of the residues may not be possible in many other countries or especially if solutions for archipelagic states are being considered. In addition the market prices for certain materials may be higher in such states, also justifying higher effort for treatment and separation of the residue streams from a waste incineration plant. And finally, if there are certain residues whichcannot be reused or disposed off within the country itself, the amount shall be minimizedas much as possible in order to reduce the costs for transport to a disposal facility.This article describes the main process steps and the required process technology tooptimize recycling rates for waste incineration plants. Most of it has been built andimplemented in commercial scale facilities by Steinmüller Babcock EnvironmentGmbH. Where a process has not been implemented on commercial scale, tests andstudies have proven that, from a technological point of view, the successful implementation

The Coolsweep Project - establishing common resources across borders within the field of waste-to-energy

Waste poses a major problem area as well as a great business potential in countries throughout the globe. Therefore, cross-regional collaboration between leading companies, universities, and public authorities is not only necessary to overcome problems of environmental degradation and pollution; it is also good business for everyone. The Coolsweep project aims to support the development of these cross-regional partnerships by establishing research driven collaboration between leading European stakeholders within waste-to-energy. The project partners include five major European cleantech cluster organisations, two universities and one cluster analysis organisation deriving from Italy, Spain, Denmark, Austria, Norway, and Latvia.
bifa-Text Nr. 57: Die Abfallwirtschaft im Jahr 2030 - Eine Szenarioanalyse nicht nur für Bayern
© bifa Umweltinstitut GmbH (5/2012)
In einer neuen Studie des bifa Umweltinstituts werden mögliche Entwicklungen der regionalen, nationalen und internationalen Rahmenbedingungen für die bayerische Abfallwirtschaft im Jahr 2030 dargestellt sowie deren Auswirkungen auf die Abfallwirtschaftsstrukturen und auf die Ökoeffizienz. Das Projekt wurde im Auftrag des Bayerischen Staatsministeriums für Umwelt und Gesundheit durchgeführt. Die Ergebnisse bieten auch anderen Behörden, Unternehmen und Verbänden in Deutschland eine Basis für die eigene Positionierung und Strategieentwicklung.

Growth Potential for Energy-from-Waste Plant Operators in the European Union and Beyond
© TK Verlag - Fachverlag für Kreislaufwirtschaft (9/2016)
Across Europe, there is growing recognition that energy, raw materials, environmental and security policy can all be components of an interdependent policy strategy, and that waste management also plays a role at the intersection of these policies. The European Commission is currently preparing a Communication which will explore the contribution that energy from waste (EfW) can make to the European Energy Union. The Energy Union is designed to reduce the EU’s reliance on energy from Russia, following the dramatic events in Ukraine. The EU’s strategic energy and security goals create an opportunity to implement the longstanding EU waste Management targets, particularly with regard to landfilling.
