Treatment of Liquid Hazardous Waste and Highly-Loaded Industrial Wastewater by photo-Fenton process, using a Newly-Developed Photo-Reactor including Noxiousness Assessment
© DGAW - Deutsche Gesellschaft für Abfallwirtschaft e.V. (6/2011)
Recently about 145 000 substances are identified which play an important role in global economic life. Since most of these substances sooner or later become components of waste and wastewater, one of the major tasks of environmental technology is to remove these substances from the biosphere, mainly by microbiological degradation in sewage plants. In order to get rid of remaining hardly degradable hazardous substances, chemical-technical destruction methods prior to biological sewage treatment must be developed – e.g. by using extremely strong oxidizers, like OH radicals.

Mercury Recovery from Solid Hazardous Wastes by Thermal Desorption
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2010)
This paper reviews basic principles, applicability, advantages and limitations, methods of predicting and improving performance of thermal desorption plants for highly mercury-contaminated solid wastes. The discussion is based on a review of previously performed bench scale tests and field applications using thermal desorption systems which have been undertaken, mostly with mercury-contaminated soils from Buna Schkopau and the Chemical Factory Marktredwitz (CFM).

Improvement of hazardous waste management in Turkey through introduction of a web-based system for data collection and quality control
© Wasteconsult international (6/2010)
The Waste Framework Directive (WASTE FRAMEWORK DIRECTIVE, 2008) specifies certain measures to ensure that waste is recovered or disposed of in accordance with Article 13, i.e. without endangering human health or harming the environment. Specific measures laid down in the WFD include the introduction and common use of appropriate classification systems (LoW: Art. 7; recovery and disposal codes: Annex I and II), the principle of producer responsibility (Art. 14, Art. 15), the issue of permits for waste treatment facilities (Art. 23), the drafting of waste management plans (Art. 28), the requirement that the actors of waste management shall be subject to appropriate periodic inspections (Art 34) and their obligation to keep records on their activities (Art. 35).

Hazardous waste classification and re-use (end of waste) by New Waste Directive, CLP and REACH Regulations
© Wasteconsult international (6/2010)
Hazardous waste’ means waste which displays one or more of the hazardous properties H. Attribution of the hazardous properties H is derived from risk phrases R coming from Directives 67/548/EEC and 1999/45/EC. New CLP Regulation (repealing above Directives) in place of risk phrases R introduces hazard statements H. That means, that soon we will derive hazardous properties H (1 or 2-digit) from hazard statements H (3-digit) of it’s components.

Low-energy lamps create problem waste: The fate of the light bulb is sealed in Europe
© Deutscher Fachverlag (DFV) (6/2010)
After 130 years, Europe bids farewell to the incandescent light bulb. Conventional bulbs are too inefficient, too expensive, and too harmful to the climate. But the switch to low-energy lamps is not without consequences for the environment -- not, at least, as long as there is no adequate disposal system for the mercury contained in the new lamps. All low-energy lamps, most of which are manufactured in Asia, contain the poisonous heavy metal mercury.

Hydrofluoric acid neutralised: Disposal bottleneck for uiquicl special waste elimination
© Deutscher Fachverlag (DFV) (6/2010)
A state-of-the-art plant for neutralising (highly) toxic liquid production residues, which was also planned according to the latest safety standards, started operation near Leipzig (East Germany) last year after taking just six months to build. This especially alleviates a bottleneck in the disposal of hydrofluoric acid caused by increasing demand for products in various industries.

Biomass waste as an alternative energy source in Asturias (Spain)

The aim of the present study was to evaluate the potential amounts of biomass resources that can be used to generate energy in Asturias, a region in Northern Spain.

Waste reduction methods for shipyards: dry ice blasting
© Aristotle University of Thessaloniki (6/2009)
Shipbuilding industry is listed as heavy industry due to the use of raw materials and production processes, which are mostly effective on human health and environment as contaminant. Various types of solid, liquid and gaseous form of wastes are known as the outcome of shipbuilding and ship repair processes. These contaminants may affect water, air and soil unless preventive actions are considered. The effect of these contaminants on workers health is as important as environmental effect.

Plasma gasification for waste treatment and energy production

The application of various technologies that convert Municipal Solid Waste (MSW) to energy and other by-products for beneficial reuse has become an issue at the forefront of integrated solid waste management.

Environmental impacts of unmanaged solid waste at a former base metal mining and ore processing site (Kirki, Greece)
© Aristotle University of Thessaloniki (6/2009)
During this program, a typology of mining waste was established, and the environmental hazards related with each type of waste were evaluated. Critical toxic species were identified, such as cadmium and cyanide. The local stormy rainfall regime and hilly topography are additional unfavourable parameters, allowing the release of large amounts of pollutants as a flushing effect of stormy events.
