Modelling of Solid Recovered Fuel (SRF) Properties Based on Material Composition – Chloride Quality
© TK Verlag - Fachverlag für Kreislaufwirtschaft (9/2016)
Producing solid recovered fuels (SRF) is a well-established route for recovering energy resources from municipal solid waste (household and/or commercial). Chloride content critically impacts the quality of SRF. It directly influences operation of thermal processes, having deleterious effects through the high temperature corrosion of the boilers and through demands placed on the flue gas treatment (FGT) system, which could impact emissions control. Whereas design and specification of process plant can mitigate the technical issues associated with the presence of chloride experienced during thermal treatment, processing such fuels is associated with increased capital, operating and maintenance costs. This, at best, restricts the uptake/use of SRF or increases the cost of its treatment towards achieving a reduced chloride content.
Recommendations for the Limitation of Greenhouse Gas Emissions from Open Windrow Composting Facilities

In 2006, the German Federal Environmental Agency (UBA) commissioned Ingenieurgesellschaft für Wissenstransfer GmbH (gewitra) in Troisdorf to carry out a study entitled "Determination of the Emission Situation of Biowaste Recovery Activities“ (UFOPLAN 2006, FKZ: 206 33 326). The findings of this study were complemented by additional assessments in a follow-up study "Determination of the Emission Situation of Anaerobic Biowaste Digestion Facilities and Determination of the Emission Situation of Biowaste Recovery in Open Composting Facilities" (UFOPLAN 2009, FKZ: 3709 44 320) likewise carried out by Ingenieurgesellschaft für Wissenstransfer GmbH, Troisdorf. The results of these two studies characterize the current state of the knowledge on greenhouse gas emissions from biowaste treatment activities.
Development of an Ecodesign Tool for the Aircraft Industry

Each year over 2.2 billion passengers travel by plane. Over the next 20 years an increase of 4-5 % per annum is predicted combined with a doubling in the commercial aircraft fleet until 2050. The challenge is to meet the growth in an environmental friendly way.
Mass Flow Analysis and Economic Evaluation of Informal Sector Activities
© DGAW - Deutsche Gesellschaft für Abfallwirtschaft e.V. (3/2012)
The thesis will analyze mass flows and estimate corresponding monetary flows in three different key areas: Rio, Brazil; Delhi, India; Germany-Poland. A focus is put on formal and informal amounts, impacts on recycling quotas, advantages and disadvantages for waste management systems, legal barriers, political incentives and economic drivers to regulate informal activities and find differences and common grounds regarding waste management systems. The current contribution highlights the economic drivers and incentives that cause informal activities and presents results regarding the informal sector in Germany.
Waste disposal strategy for better quality of life: Asia and Europe in search of solutions for controlled waste management
© Deutscher Fachverlag (DFV) (6/2010)
The largely unregulated waste management poses grave problems in many Asian cities. The need to organize waste management systematically and communicate this to people requires a lot of awareness training, good networking, a clear focus on results and a great deal of patience. Key individuals on all levels must be involved in order to increase acceptance among the population. The Technologie-Transfer-Zentrum, ttz (Technology Transfer Centre, ttz) in Bremerhaven, Germany, is aiming to develop and locally implement a realizable model
with 21 partners from Europe and Asia, within the EU project ISSOWAMA (Integrated Sustainable Solid Waste Management in Asia). The project was officially launched in Bangkok on February 11 and 12.
Environmentally focused production and distribution supply chain network structures

Enterprise optimisation can rapidly strip significant “bottom line” costs out ofglobal operations, giving companies a real competitive edge. Traditionally, the main objective of such optimisation models and methods has been to maximise the financial benefits by integrating operational, design and cost decisions. Over the last decade there has been a growing concern for the environmental impact of design and operational decisions.
Continuous Measurement of Waste Material Volume Flow
© Wasteconsult international (6/2009)
At the present time, volume flow rates in waste treatment plants are determined only discontinuously. With the aid of a contactless, sensor-based method the volume of theconveyed waste stream can be detected in real-time. In addition, nformation about the locations of the transported materials can be given. The data can be used to monitor and control aggregates. The procedure is applicable to all regular facilities of waste treatment plants.

Separating the Wheat from the Chaff:Regulating Greenhouse Gases in a Climate of Uncertainty
© Lexxion Verlagsgesellschaft mbH (11/2007)
Reliance on the word “climate” in the title of this article is a deliberate pun. The phenomenon of
global climate change requires a drastic reduction of greenhouse gas emissions, especially from the
stationary energy sector, if the concentrations of greenhouse gases (GHGs) in the atmosphere are to
be contained at current levels and prevented from escalating dramatically in the future.
