Enhancing of the Energy Efficiency of an Existing Waste Incineration Plant by Retrofitting with a District Heating Network
© TK Verlag - Fachverlag für Kreislaufwirtschaft (9/2016)
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.

Real-time Analysis of Solid Recovered Fuels using Sensor Technology

Quality assurance plays an important role for the production and utilization of solid recovered fuels (SRF) generated from municipal solid and production waste.

Framework Requirements for Harmonising Food Waste Monitoring
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2014)
The overall problem when comparing food waste data is the lack of a common food waste Definition as well as different methodological approaches in use for quantifying food waste throughout the food supply chain (FSC). Both challenges are targeted by the FP7-funded project FUSIONS which runs between years 2012-2016.

SolidWasteSim – Simulation of Solid Waste Treatment
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2014)
A critical analysis of mechanical processes in waste treatment plants hints at vulnerable spots in the interaction of plant units and deployed heterogeneous materials. The Simulation of mechanical processes in waste treatment may depict the total material flow in a plant and as such, contribute to a better understanding of the behaviour in heterogeneous materials, to identify bottlenecks, to check plant modifi cations and hence, to support planning and reducing time for implementation period.

Leakage control of Biogas plants

Anaerobic digestion has become a very important technology to treat organic waste and to generate renewable energy. During construction and operation leaks at biogas plants may occur and methane is emitted. Further Authors: S. Neitzel - Systemtechnik Weser-Ems S. Kohne - esders Ltd

Composting of pic Faeces with corn stalks in China - Microbiological examinations; hygienic aspects and sanitation capacity
© European Compost Network ECN e.V. (6/2012)
With the increasing demand for meat (pork) the pig production in China increased over the last years,especially in the Northern East of China around mega cities like Beijing. Increasing pig production in large scale pigfarms head to enormous amounts of organic wastes (such as pig faeces), over-fertilization of agricultural areas andenvironmental pollution in regions with high pig production and density.

Effect of operating Parameters during compost stability Respiration activity tests
© European Compost Network ECN e.V. (6/2012)
The goal of this work was to assess the effect of various operating parameters (sample size, temperature, air flowrate)during static and dynamic respiration activity tests that are used to assess compost stability. The material used in allexperiments was a MSW compost derived from a commingled MSW composting facility in Athens, Greece. Thefacility receives raw commingled MSW that go through several pre-processing steps, an active in-vessel compostingstep of 18 hr and 6 weeks and a final curing period of 5-6 weeks.

Innovative revamping MBT plants - A portuguese case study
© European Compost Network ECN e.V. (6/2012)
Biodegradable municipal waste technologies in Mechanical and Biological Treatment Plants (MBT plants) are gainingmomentum throughout Europe and the world. These waste management technologies consist of several mechanical andbiological stages that progressively recover and stabilise the biodegradable matter under controlled anaerobic and/oraerobic conditions.At the same time, Materials Recovery Facilities (MRF plants) are being built in order to sort by different material thepackaging waste at-source collected.

MBT scrubber effluent: Wastewater or fertiliser?
© European Compost Network ECN e.V. (5/2012)
The design of waste air cleaning in Mechanical Biological Treatment (MBT) plants frequently includes acid scrubbing followed by biofiltration. The main purpose of the former process is to remove ammonia from the exhaust air, which produces odours and is toxic for the biofilter microorganisms. The ammonia is then solubilised as ammonium sulphate or ammonium nitrate, according to the acid used in the scrubber (sulphuric or nitric acid, respectively). When the washing solution reaches a preset conductivity, it is partially discharged and replaced by fresh water. As a consequence, an effluent with high ammonia concentration is produced, which is difficult and expensive to treat in a waste water treatment plant. Yet, if we see it in the agronomical perspective, an ammonia rich solution may not be a pollutant but a fertiliser. Further Authors: H. Ribeiro - Technical University of Lisbon D.

Influence of Aerobic In-Situ Stabilization of Old Landfills on Leachate Quality and Quantity
© DGAW - Deutsche Gesellschaft für Abfallwirtschaft e.V. (6/2011)
Many landfill sites are being closed and converted into the aftercare period in Germany, as a direct consequence of the landfill ban for untreated biologically degradable organic waste that entered into force on 1st June 2005 (EEA Report No 7/2009). Today these landfills are still emitting landfill gas and highly polluted leachate to the environment since they are not equipped with sufficient protection barriers.
