The great variety of available Solid Waste Management System (SWMS) models, along with a plethora of continuously developing technological advancements in the design and operation of the treatment facilities and collection and transport schemes, the continous updating of national (and/or European) regulations on waste management and the increased computer literacy and availability, renders the selection of a SWMS model a complex endeavor. From the view point of a municipality, the following ques...

The Kyoto target for Romania was to reduce its carbon dioxide emissions by 8 % from the 1989 levels. The 1989 emissions were around 260 million tones. In 2000 the net CO2 emission - some 125 million tones - were 54% of the net CO2 emission in the reference year -1989, leaving some 115 million tones as a reserve or as a tradable resource to other countries that can not met their Kyoto targets. Assuming that Romania will sell 100 millions tones of its extra quota in accordance to Article 17 under ...

Abstract:There is a growing concern that the Earth’s atmospheric composition is being altered by human activities which can lead toclimate change. Policy measures to reduce carbon dioxide emissions are on the agenda of the International Maritime Organization(IMO) and the European Union (EU). Climate Change is an environmental problem and answers have to be sought among robustenvironmental policies that are often classified in market-based, command-and-control and voluntary instruments.

AbstractNowadays, when the problem of environmental protection is quite stringent, the producers are concerned to bring on the marketproducts, which have reduced environmental impact. In their turn, the consumers have become more aware and selective inpurchasing products or services. Due to the financial crisis, consumers buy less but they are asking for quality and environmentalfriendly products. Under these circumstances the producers must find solutions in order to satisfy the consumers’ requ...

AbstractThis paper will focus on the 2012/27/EU Energy Efficiency Directive (EED). Because the EED is a rather new legal act, itsassessment from an environmental law perspective has been neglected in the scientific literature. The previous regulation(Directive 2006/32/EC on end-use energy efficiency) has already been analyzed from an ecological point of view (Bányai, 2013).Therefore, the next question automatically arises: does the new directive take steps to improve the European Union (EU)regul...

Abstract This paper investigates the role of collective organizations created by producers to comply with the WEEE Directive. There are limited case studies on these producer responsibility organizations (PROs) despite the crucial role that they play in Extended Producer Responsibility (EPR) schemes. An important aspect in order to evaluate the efficiency of these compliance schemes is the analysis of their internal costs including transaction costs. First of all, this research provides an u...

In quarries, hard rock blasting is done effectively using explosives for civil use. Perhaps, the most used technical solution for decreasing the seismic effects due to blasting is sequential blasting in front of the quarry. This technical solution involves the use of proper means of initiating explosives, which have to meet certain characteristics able of leading to the achievement of the intended purpose.

Thessaloniki’s suburban forest is environmentally protected by law and also characterized as a high-fire-risk forest. It has a high road density due to its proximity to a city of 1.3 million. Following the disastrous fire of 1997, a number of rehabilitation works were conducted in the 2005- 2009 period along existing road routes. The existing environmental protection laws are not sufficient to assess the environmental impacts of these works within the forest environment. A method has been ...

At the construction of a bridge in the riverbed, the water flow section is usually reduced due to the placement of the piles and abutments of the bridge between the banks. How the water flow change depend on the flow regime (fast-supercritical or slowsubcritical) existing in the river in the absence of the bridge. Of interest is the change of the water level in the section of the bridge and upstream of the bridge. The water level may rise or fall depending on the flow regime (slow or fast) and t...
