Environmental effects of fireworks with special consideration of plastic emissions
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
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.

Multi-Criteria Assessment of Landfill Mining Projects

Landfill mining views landfills with the aim of regaining secondary resources from deposited landfill material. In this respect, landfi ll owners are faced with the decision of whether to leave their landfills in aftercare, for example, or start a landfill mining project. In order to be able to make this decision, the landfi ll owners must have the right aid in decision making.

Resource Efficiency in the German Steel Industry
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2014)
Recovery and recycling of metals from residues is important for protecting our natural resources. Therefore we identified approaches for the utilization of residues of the German steel industry to improve resource efficiency. The study focuses on the residues blast furnace sludge, basic oxygen furnace dust/sludge and electric arc furnace (EAF) dust. The objective of the study was to find further, more efficient connections between process chains.

Decoding interdependencies between primary and secondary raw material markets by means of the Capacity Model
© Wasteconsult International (5/2011)
On the basis of the well-known life-cycle-concept the Capacity Model presents an explanation approach for the interdependencies between primary and secondary raw material markets alongside the life-cycle of different waste materials. Depending on site capacity and waste amount the price for a certain waste material is either determined by the disposal market or the energy and raw material market.

Alternatives to wheeled loaders: Tracked conveyors and program-controlled conveyor belts have advantages:
© Deutscher Fachverlag (DFV) (6/2010)
Wheeled loaders are still indispensable working machines in many companies – also in construction material recycling plants. They are used because of the long operating hours they are capable of. In addition to the final loading, in many cases intermediate stockpiles are created, although these can result in considerable costs and risks.

Industrial quality raw material: Mixed PET plastic can be prepared for mechanical recycling
© Deutscher Fachverlag (DFV) (6/2010)
The Fraunhofer Institute for Chemical Technology ICT in Pfinztal-Berghausen near Karlsruhe (Southern Germany) has developed and tested a process to prepare mixed PET (polyethylene terephthalate) from sorted packaging waste for mechanical recycling. The material can be used for injection moulded parts in technical applications.

Paper export with opportunities and risks: The financial crisis leads to market adjustment in the paper industry
© Deutscher Fachverlag (DFV) (6/2010)
The global financial crisis has also reached the German recycling industry. But as opposed to the banking and automotive industries, the recycling industry has not responded with panic or predictions of Armageddon. Admittedly, there are some problems with exporting wastepaper to China, but in Germany the industry sees more opportunities than risks. In any case, there will be some form of market adjustment. An important representative of the German disposal industry and an expert in the area of wastepaper expresses his views on the situation in the global market. Lutz Siewek is Managing Director of Nehlsen GmbH & CO. KG in Bremen (Germany), where he is also responsible for the company's entire raw materials business.

Complete utilisation of plastics: A study looks at the consumption and utilisation of plastics in Germany
© Deutscher Fachverlag (DFV) (6/2010)
Consumption of plastic in Germany continues to increase. The issue of waste utilisation in Germany has been clarified: more than 96 per cent of plastic waste is now utilised. Consequently, plastics are an important resource even after their first usage phase.
