Alternative energy sources in transition countries. The case of bioenergy in Ukraine
Environmental Engineering and Management Journal › Vol. 6 › Nr. 1 AbstractDuring the transition to a market economy, many countries with a planned economy in Central and Eastern Europe face similar challenges when the established socio-economic systems and infrastructures deemed inefficient in a market economy. Also new issues are being raised by the trends of globalization and the vision of sustainable development. In the energy sector the challenges raised by the Kyoto Protocol and its implementation mechanisms are especially interesting, because they are in...

Ecological Economics And Transport Systems
Environmental Engineering and Management Journal › Vol. 6 › Nr. 1 AbstractEcological economics is an emerging field that offers significant room for creativity and innovation at the conceptual level on how to operationalize sustainability. It integrates economics with ecology and many elements from both the natural and social sciences to provide an integrated perspective on environment-economy interactions. A major policy dilemma that ecological economics addresses is how policy-makers can influence markets, so that they receive the 'right' signals from the na...

Municipal pricing of water considering that water is both an economic and a social good - a pricing reform with implications for Romania
Environmental Engineering and Management Journal › Vol. 6 › Nr. 5 AbstractOne of the basic principles in the European policy to cope with the growing challenge of water scarcity is that water demand management should be considered before opting for additional water infrastructure. The implication of this is that water must be treated as an economic good, which means that the "user's pays' principle"has to be implemented. At the same time there is much political consensus that the water price has to be "equitable". Water can be subsidized without violating the ...

CITRUS AS A MULTIFUNCTIONAL CROP TO PROMOTE NEW BIO-PRODUCTS AND VALORIZE THE SUPPLY CHAIN
Environmental Engineering and Management Journal › Vol. 19 › Nr. 10 Citrus is one of the most important fruit tree crops worldwide, with respect to both total production and economic value. About 80% of the world production is destined to the fresh market, the remaining is processed to obtain various products (juices, jams, etc.). Citrus processing residues account for about 50-60% of processed fruits; their huge amounts and peculiar characteristics need a correct management that imply cost for producers and processors. If not well managed, they can represent an... Autori: Paola Sangiorgio ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28309
EVALUATION OF REMEDIATION TECHNOLOGIES FOR CONTAMINATED MARINE SEDIMENTS THROUGH MULTI CRITERIA DECISION ANALYSIS
Environmental Engineering and Management Journal › Vol. 19 › Nr. 10 Remediation of contaminated marine sediments present a difficult challenge for environmental decision-makers. In socially relevant situations, as in the Mar Piccolo of Taranto case study (Southern Italy), the decision-maker needs to explain to the citizens
why some remediation technologies are adopted compared to others. Multi criteria decision analysis (MCDA) is a scientifically sound decision tool for management of contaminated sites, not only to denote effective or technologically and econom...

SYNTHESIS AND APPLICATION OF AN EFFICIENT DEGREASING AGENT FOR OILY DRILLING CUTTINGS
Environmental Engineering and Management Journal › Vol. 19 › Nr. 11 Oil-based drilling fluids are widely used in oil and gas exploration and development. Large amounts of oily drilling cuttings are produced in the drilling process, and improper treatment can cause serious secondary pollution. Chemical cleaning is commonly
used to treat oily drilling cuttings. However, most degreasing agents are not environmentally friendly and can cause secondary pollution. Thus, the processing requirements of oily cuttings are difficult to meet. In this study, an environmental... Autori: Zhiyong Li ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=28313
DYNAMIC VISUALIZATION OF SPATIO-TEMPORAL PROCESS MODEL BASED ON NetCDF AND OPTIMAL INTERPOLATION FOR MARINE ENVIRONMENT
Environmental Engineering and Management Journal › Vol. 19 › Nr. 11 The ocean is an indispensable source of materials and energy for the survival of human beings and social development. It is also an essential factor affecting climate change and ecological balance. In view of the dynamic, three-dimensional (3D), and complex
marine environment, this study proposes the construction and dynamic visualization of a marine spatio-temporal process model based on Network Common Data Form (NetCDF) and optimal interpolation. The proposed model combines the advantages of
