Waste-to-Energy installations generate around 25 percent bottom ashes, that may be considered non-hazardous waste. On a total of 76 million tonnes of incinerated waste, this means a total of roughly 19 Million tonnes of bottom ashes.
Separation of the bottom ashes in several fractions and recycling of the metals and stony fractions facilitate the further integration of Waste-to-Energy (WtE) technology as part of a circular economy. Recycling of metals and utilization of bottom ash will substitute the mining and manufacturing of virgin material, thus lowering the burden on our natural resources. The increased awareness on resource recovery potential in and of the bottom ash has caused substantial developments, such as more efficient separation techniques and alternative process solutions. The scope oft his article is to give an overview of the current status of bottom ash treatment and the potential uses of the mineral and metal fractions.

Der Markt für Waste-to-Energy – Entwicklungen und Trends bis 2030
© Witzenhausen-Institut für Abfall, Umwelt und Energie GmbH (10/2021)
Der Beitrag „Der Markt für Waste-to-Energy – Entwicklungen und Trends bis 2030“ stellt dar, wie sich die Abfallentsorgung und insbesondere die energetische Verwertung in Deutschland in den kommenden Jahren entwickeln werden. Dabei werden auch Teilmärkte, wie der Markt für Klärschlamm(mono)verbrennung oder der für Biomasse/Altholz, dargestellt.
Development of local municipal solid waste management in the Western Transdanubia region of Hungary

Hungarian municipal solid wastes (MSW) management has developed tremendously over the past 15 years. More than 3,000 landfills and dumps had been closed, just to mention one improvement. However, still, lots of work is necessary to accomplish the EU’s ambitious aim of decreasing landfilling and increasing recycling and composting.
Life cycle assessment of waste wood used for energy production – Methodology and case studies
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
To assess the sustainability along the whole value chain, life cycle-based methodologies have been developed over the last years. Life Cycle Assessment (LCA) considers environmental impacts along supply chains, from extraction of raw materials to end-of-life of products (ASI 2006). The aim of this paper is to describe the use of LCA to assess the environmental impacts of the use of waste wood for energy production. Important methodological aspects on the use of LCA for the assessment of waste wood are presented using two different case studies from the H2020 projects STORY (Added value of STOrage in distribution sYstems) and TORERO (TORefying wood with Ethanol as a Renewable Output: large-scale demonstration).
Environmental effects of fireworks with special consideration of plastic emissions

In Germany, about 133 million Euro are spent annually for New Year’s Eve fireworks, which result in 38,000 to 49,000 Mg of total firework mass. By a com-bination of desk research with official fireworks approval statistics, a customer survey, dismantling experiments with fireworks debris and with packaging characterisation, the total nationwide polymer emission was estimated to be 3,088 Mg. Out of this total mass, a projected polymer debris mass of 534 Mg was identified, and about 270 Mg of polymer packaging material. The remaining 2283 Mg of polymer mass are parts that eventually may remain at the launching site.
