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.

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.

Vermicomposting of Unsorted Municipal Solid Waste
© Wasteconsult international (6/2009)
The Vermicomposting (aerobic composting with red earthworms) of unsorted mixed Municipal Solid Waste (MSW) being pioneered by Lavoisier, a Portuguese enterprise, with the support of the NGO Quercus, is an adaptation of an organic waste treatment technology that has been around for a long time. The innovation is the application of earthworm composting to the treatment of mixed MSW allowing immediate diversion from landfill and high levels of separation of recyclables. The process, installed by the AMAVE - Municipal Association of River Ave Valley, includes a pre-composting phase in order to prepare the waste to feed the worms.Through pre-composting organic waste is digested by aerobic micro organisms. After this phase worms are fed with waste and digest the remaining organic matter, producing humus and cleaning plastics, glass and metals.

Advances in waste processing and diversion from landfill in Australia
© Wasteconsult international (6/2009)
Alternative waste technologies are expected to be the main focus for improved processing and resource recovery of municipal wastes in the immediate future. There is scope to extend this to commercial wastes. In NSW, there are already three AWT facilities in operation, two more being built and two more planned to be operating by 2010. This paper discusses current progress in implementing AWT in Australia, and provides an update of recent projects and factors driving the implementation of new waste technologies in Australia. Keywords: Alternative waste technology, AWT, sustainable waste management

Inactive Asbestos Mine as a Disposal Site for Asbestos wastes
© Verlag Abfall aktuell (2/2008)
Asbestos is a silicate mineral of fibrous form and has been used for many years as a raw material for the production of a large variety of materials and objects by virtue of its exceptional attributes. Unfortunately asbestos is considered responsible for serious lung diseases such as asbestosis, mesothelioma and lung cancer that are caused by the inhalation of asbestos fibres and appear usually after a long period of exposure. Although, according to European legislation the use of Asbestos Containing Materials is forbidden, many buildings in Greece still contain asbestos products, which must be removed at some point in the near future. It must be pointed out that even nowadays Greece has no special landfill sites for the disposal of Toxic & Hazardous wastes. This means that all hazardous wastes, asbestos included, must be transferred abroad. This fact has enormous economical and environmental consequences for the Greek state. A suitable site must be found in the future that can serve as a disposal site for hazardous wastes. The case of the asbestos mine of northern Greece represents an interesting case as a potential disposal site for asbestos wastes in the future. The existing data regarding the quality of the environment in the Asbestos Mine of Northern Greece (known as MABE) region in relation to the presence of asbestos are insufficient for the determination of the existing pollution problem. In the present work, a first approach of this problem and a toxicity analyses have been carried out.

PROPOSAL OF A METHODOLOGY FOR ASSESSING THE FINAL STORAGE QUALITY OF A LANDFILL
© IWWG International Waste Working Group (10/2007)
The long-term emission behaviour and sustainability of landfills is a fundamentally important issue. Although no conventional definition of sustainable landfill has been established, there is general consensus throughout the scientific community that a landfill can be considered sustainable if emissions do not significantly modify the quality of the surrounding environmental compartments: air, water and soil (Hjelmar and Hansen, 2005; Stegmann et al., 2003).

According to the Austrian Landfill Ordinance of 2004, pre-treatment of specific kinds of waste is mandatory to achieve the high quality standards for landfilled residues.

Experiencing resource management - decentralised biological treatment at schools of Bangkok

The politics of Thailand is set out for combining the increase of the industrial production with a higher standard of the living conditions of wider parts of the Thai society. In order to secure the basic fundament and quality of life to next generations, Thailand is challenged to create and close energy and material circles.
