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...

AbstractThe paper discusses some environmental problems caused by the presence of the copper mining and processing complex in the Bor area (Eastern Serbia). The Bor area is a serious hot spot in Serbia. Unsupervised operation of the mining company RTB Bor, without any protective measures, has led to extreme pollution of the Bor River, the Danube and underground waters, soil pollution with heavy metals, air-pollution with sulfur-dioxide etc. Recommendations are suggested as follows: a sustainable...

An increased level of environmental awareness by consumers has caused marketing to pay special attention to the deteriorating environment. This is a consequence of markets punishing those companies that fail to consider environmental concerns in their marketing efforts.

Abstract Waste management does not try to dispose waste anymore but is searching for the best solution to manage valuable and scarce resources and reduce the negative impact on the environment. Preoccupation in Germany with regard to optimization of waste recuperation and valorization increases and separate collection systems for different waste fractions are taken into consideration. Within this study a pilot project was set up and its results are presented below. The investigation evaluate...

Abstract Transparent and participatory decision making in solving complex forest management problems are fostered by numerous forest policies. Thus, all relevant stakeholders should be involved in the process of evaluating forest road options from the early stages of planning. However, participatory tools are not yet used as a matter of course in the Romanian forest sector. This study aimed to stress the importance of corporate social responsibility (CSR) in decision making in the forest sec...

Abstract The traditional industrial parks (TIPs) in China has been rapidly developed in the past 30 years, which have contributed to stable and continuing GDP growth, but also caused severe pollution. In order to solve the conflict between local economic development, environmental pollution and resource shortage, the TIPs in China should be transformed to eco-industrial parks (EIPs). However, the eco-transformation of China's TIPs is still at an exploratory stage. So, the paper studies e...

The potential of Sphagnum moss peat to adsorb oxyanions (As(III), As(V), Sb(III), Sb(V) and Se(VI)) from aqueous solution was studied in batch mode. For arsenic (both species) and selenium, the results were negative: moss peat is not able to retain these oxyanion. For antimony, the hydroxyl and carboxyl groups from the Sphagnum moss peat surface seems to be responsible for Sb uptake. Kinetic studies were conducted for both Sb(III) and Sb(V) and a fast uptake process was observed, equilibrium bei...
