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).

Zinc release kinetics in a calcareous soil treated with waste tire ash and powder as alternatives to Zn fertilizers
© Aristotle University of Thessaloniki (6/2009)
The aim of this work was to study release kinetics of zinc from a soil treated with waste tire ash and powder and to compare it to a commercial Zn fertilizer and to a laboratory grade zinc sulfate. A Zndeficient soil was chosen from a wheat field in Isfahan province, central Iran. The soil Zn concentration was elevated to the equal and four times of the soil Zn critical deficiency concentration.

A greenhouse experiment investigating the effects of sewage sludge on nickel availability in soil and maize

Fertilizers are commonly used as a tool to reach maximum yield. Generally application of biosolids on agriculture land as fertilizers is more practical in many countries because of their low price. Sewage sludge includes high levels of macro and micro nutrients that may also cause the high concentration of heavy metals in soil but can be effective on maize yield (unclear meaning). Sewage sludge may have high concentration of heavy metals that can be transfer to the human food chain. Therefore, it is important to reduce the soil pollution from these compounds.

Investigation on material separation of mixed construction and demolition waste by sorting process
© Aristotle University of Thessaloniki (6/2009)
The final disposal ratio of mixed construction and demolition waste (MCDW) remains high in Japan, while progress has been made in the recycling of other construction and demolition waste. Sorting facilities are expected to play an important role in better management of MCDW. In this study, the feasibility of sorting facilities for the separation of material and of pre-treatment for final disposal was investigated by conducting a batch experiment at an operational facility.

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.

Differences on the porosity development of carbon dioxide activated carbons from lignocellulosic residues
© Aristotle University of Thessaloniki (6/2009)
The use of almond tree pruning and almond shell for the production of activated carbons during carbon dioxide activation was investigated. Experimental results show the influence of the raw material on the porous structure of the ACs and how this influence is more marked as the activation time is increased.

Effect of material membrane on the treatment of cutting oil emulsion by ultrafiltration
© Aristotle University of Thessaloniki (6/2009)
The aim of this study is the treatment of macroemulsion by ultrafiltration process. The membrane material effect on the permeate and rejection flows was investigated. Experiments carried out with organic and mineral membranes and the samples treated were prepared with soluble cutting oil (SarelfA).

Electrochemical treatment of synthetic milk emulsion
© Aristotle University of Thessaloniki (6/2009)
The electrocoagulation efficiency of milk samples (4g/L) which are considered as an oil in water (O/W) emulsion, with the use of Al/Al, Al/Pt and Pt/Pt electrodes has been investigated. The removal of COD, orthophosphate and turbidity was investigated according to the variation of current density, material electrode, electrolysis time and initial pH.
