Current Developments in European Waste-to-Energy© ThomĂ©-Kozmiensky Verlag GmbH (12/2015)
Europe’s future Circular Economy package should be ambitious in minimising landfilling of recyclable and recoverable waste, in order to maximise the use of waste as a resource. It should take a holistic approach that considers supply of raw materials as well as supply of secure and sustainable energy, which is an important part of the European Energy Union. This approach would be in line with Better Regulation and would benefit the environment, jobs and growth in Europe.
Waste to Energy: A Sustainable Energy Strategy© Eigenbeiträge der Autoren (9/2015)
In February 2015 the European Commission presented the highly anticipated Energy Union Package and by the end of 2015 a “more ambitious” Circular Economy proposal is to be introduced.
Fracking in the United Kingdom: Regulatory Challenges between Resource Mobilisation and Environmental Protection© Lexxion Verlagsgesellschaft mbH (12/2014)
This article will outline the existing regulatory framework with regard to shale gas extraction and development in the UK and analyse potential implications for the functioning of European and UK legislation in this field with consideration of environmental provisions. Moreover, the impact on wider energy policy objectives of the individual Member States’ implementation of these guidelines will be described.
Energetic Utilization of Organic Waste and Residuals in Germany© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2014)
Biomass is currently the most important renewable energy source in Germany. Approximately two-thirds of the available residue potential in Germany is already used energetically, the thermal recovery with the use of waste wood predominates (Nelles et al. 2013). The energy potential of relevant organic waste and residuals such as waste wood (8%), straw (7%), manure (6%), industrial waste wood (4%) as well as bio- and green waste (1%) is estimated by the Agency for Renewable Energy up to 383 PJ/a in 2020 (AEE 2013).
High Efficient Waste-to-Energy Facilities© ThomĂ©-Kozmiensky Verlag GmbH (11/2014)
All countries in Europe are working hard to reduce their reliance on fossil fuels in their power and district heating production. However, for many years to come a large share of the energy supply will continue to be based on fossil fuels. Therefore, waste-to-energy (WtE) facilities will also in the future make an important contribution to reaching the climate goals, and high energy efficiency will remain mandatory for all waste treatment facilities in order to maximise utilisation of the European energy resources and limit the climate impact of energy production.
Waste Availability, Successful Regional Strategies and New WtE Projects Shaping – The Benefits and Application of the Optimization Tool NERUDA –© ThomĂ©-Kozmiensky Verlag GmbH (11/2014)
There are more than 2,000 waste-to-energy plants (WtE) in operation worldwide. Only in Europe are there facilities with an overall processing capacity of around 100 million tons. These are mainly located in Western Europe and their erection took place between 1980 and 2000 when these countries were in the process of transiting their waste management systems into more efficient forms. Even though 120 million tons of municipal solid waste (MSW) was still landfilled in 2010 in EU, the outlook for new plants within Europe in this decade is pessimistic. There are only a number of several new plants planned and the centre point of future construction has shifted to Asia.
Waste-to-Energy Plant Krakow – On the Status of Thermal Waste Treatment in Poland –© ThomĂ©-Kozmiensky Verlag GmbH (11/2014)
In the mid-nineties one of the first waste management conferences in Poland took place in Miedzyzdroje. Municipal representatives and technology providers came together to discuss the introduction of an orderly and environmentally sound waste management structure. At that time there was a spirit of optimism in that there was consensus that waste incinerators should be a substantial part of waste management with a significant market potential. In other words waste was available for projects which would be completed in the not too distant future.
Impact of Operation Mode and Design on the Energy Efficiency of Waste Combustion Plants© ThomĂ©-Kozmiensky Verlag GmbH (11/2014)
As climate issues are gaining urgency worldwide, focus is set on reducing industrial carbon footprints through fossil fuel replacement and energetic optimization of processes. This paper contains results of a study on technical options to attain a higher energetic efficiency from Waste-to-Energy (WtE) boiler & steam cycles. The aim of the study is to determine the available margins for energetic optimization of WtE plants, taking into account the particular constraints of a waste combustion process. The impacts of distinct process variables are quantified and compared. These variables include a.o. temperatures, pressures, process ratios and recycling rates, as typically applied to flows of combustion air, flue gas, steam and condensate. A few selected cases are elaborated to illustrate the cumulative effect of technical choices during the design and the operation of WtE plants. Finally, the results also enable the knowledgeable reader to determine an indicative value for R1.
