Einem Wissenschaftsteam der Ruhr-Universität Bochum ist es gelungen, Polyethylenterephthalat (PET)-Flaschen durch eine hauchdünne Beschichtung dichter, und durch eine weitere Behandlung gleichzeitig keimfrei zu machen. Das PET-Recycling ist davon wenig tangiert.

Modelling of Solid Recovered Fuel (SRF) Properties Based on Material Composition – Chloride Quality
© Thomé-Kozmiensky Verlag GmbH (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.
Wertstoffhof 2020 - Neuorientierung von Wertstoffhöfen
© ia GmbH - Wissensmanagement und Ingenieurleistungen (4/2015)
Im Jahr 2014, zwanzig Jahre nach dem durch das Bayerische Staatsministerium für Landesentwicklung und Umweltfragen organisierten Wettbewerb „Der vorbildliche Wertstoffhof“, ist es sicher angebracht, sich dem Thema erneut zuzuwenden. Was ist aus den prämierten Wertstoffhöfen der Preisträger in den jeweiligen Clustern geworden? Wie hat sich das System grundsätzlich entwickelt? Wo geht es hin, wenn man die gesellschaftlichen Anforderungen aus demografischer Entwicklung, Ressourcenschutz und Klimarelevanz betrachtet?
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.
