Environmentally benign and cost optimal phosphoric acid production through a systematic process design framework
© Aristotle University of Thessaloniki (6/2009)
In the present work we address the cost optimal and environmentally efficient design of industrial scale phosphoric acid production processes. We develop a framework that aims to facilitate the design and optimization of phosphoric acid production processes in order to propose solutions that improve the performance of the existing production technologies. The proposed framework is built upon am iterative procedure where design detail is added to the developed optimum process schemes based on evaluation of the generated designs.

A new threat from consumer goods coming from closing the loop in a

The discussion of the assessment and management of chemicals and products at the 1992 Earth Summit in Rio de Janeiro led for example to the creation of the OECD programme Globally Harmonised System of Classification and Labelling of Chemicals (GHS). The World Summit on Sustainable Development in Johannesburg 2002 encouraged countries to implement the GHS, adopted by UN ECOSOC in July 2003, as soon as possible, with a view of having the system operating by 2008.

Environmental economics of advanced regeneration methods of mineral oil using synthetic adsorbents
© Aristotle University of Thessaloniki (6/2009)
Mineral transformer oils are characterized by the European Waste Catalogue 2002 (EWC 2002) and marked with code 13 03 07. Usage of these oils as energy sources and their incineration are strictly forbidden while their transportation and storage is legislated. In addition to their complicated handling procedures, their price is steeply raising in line with recent changes in market crude oil prices.

Regional differences in trace element concentrations in Anadara spp. Mollusca: Bivalva) collected from the coast of South Vietnam
© Aristotle University of Thessaloniki (6/2009)
We measured accumulation of 21 trace elements in blood cockles, Anadara spp., collected from the South Key Economic Zone, Mekong River Delta (MRD), and Central Coastal Zone (CCZ) in Vietnam. Concentrations of As, Sr, Mo, Sn and Pb were higher in CCZ blood cockle than in those from the other two regions, whereas Hg concentration was elevated in MRD samples.

Fuzzy decision support system for assessing nitrogen fertilization in agricultural land
© Aristotle University of Thessaloniki (6/2009)
Modern conditional agriculture is based on whole field and mostly empirical approaches in defining and applying agrochemical inputs. The impact of fertilizing practices in the environment comprises of a crucial research matter. Soil nitrogen in its nitrate form is the most mobile nutrient, meaning that is easily leached out of soil system, increasing environmental risk.

Risk assessment for the use of mixed waste composts on previously developed land in the UK
© Wasteconsult International (6/2009)
Within the current regulatory framework in the UK the most significant land-based outlet for MBT compost in the UK is likely to be previously developed land (PDL). If MBT compost is to be successfully and sustainably applied to PDL over time, there is a need to assess the potential environmental and human health risks of such an activity in a proportionate and robust manner. Such an assessment would provide a clear framework through which informed decisions could be made by both environmental regulators and the regulated community alike. This paper will describe the potential scale of future MBT compost production in the UK and potential applications for the material on PDL, as well as approaches to the assessment of the degree of risk involved in doing so. Keywords: MBT, compost, Previously Developed Land (PDL), risk assessment, market opportunities 1 Introduction 2 What is MBT compost and how much of it is there? 3 The extent of Previously Developed Land in the UK 4 Existing guidance on the application of MBT compost in the UK 5 The potential hazards in MBT compost 5.1 Potential biological hazards 5.2 Potential chemical hazards 5.3 Potential physical hazards 6 Risk assessment 6.1 Risk to Humans 6.2 Risks to the Environment 6.3 Approaches to risk assessment 7 Conclusions

On Global Treaty Relations – Hurdles on the Way towards a Universal Civil Nuclear Liability Regime
© Lexxion Verlagsgesellschaft mbH (1/2009)
„A special regime for third party liability should as far as possible provide a uniform system for all Western European countries. The effects and repercussions of a nuclear incident will not stop at political or geographical frontiers and it is highly desirable that persons on one side of a frontier should be no less well protected than persons on the other side. For these reasons, an international agreement setting up such a regime is desirable. Such an agreement, supplementing the measures applied in the related and important fields of public health and safety and the prevention of accidents, may also facilitate the solution of third party liability problems at a national level.“

Copper mining industry is the main economical sector in Chile, being also one of the most important regarding solid waste and atmospheric emissions generation. In addition, crushing processes in mining industry generate large amounts of fine particulate matter to the working and atmospheric environment.
