Large areas of soil are historically contaminated with petroleum hydrocarbons, mainly due to lack of environmental protection legislation and careless oil extraction in the past. In some cases, one of the potential remedial actions may be the bioremediation of the oil contaminated soil, due to low cost and low environmental impact. The focus of thi...

The aim of the present paper was to illustrate certain methods and the associated experimental procedures for determining the main defining characteristics of rechargeable batteries that may be used for powering various autonomous sensing devices and also a selection method/criterion to determine the most suitable rechargeable battery to be used in...

One of the causes of climate change is the accumulation of greenhouse gases (GHGs). Methane (CH4) is one of the greenhouse gases, with an ability to trap heat in Earth's atmosphere 21 times greater than carbon dioxide (CO2) per unit mass and in the same period of time. Because the lifetime of methane in the atmosphere is relatively short, it could...

Using sludge with dangerous substances content as an agricultural fertilizer can provide risks for humans and all environmental components. An important risk factor that had to be taken into account is the combination of sludge used as a fertilizer and agriculture activities that has its own consequences. In this paper, a risk evaluation for sludge...

Paper approaches theme of energy efficiency and sustainable energy use in WWTPs, by evaluating them separately, as an independent case. Chemical loads of nutrients from wastewater, flow rates, technological lines with different treatment technologies and equipments used, and also power and heat consumption are not the same in all cases, WWTPs do no...

The anaerobic digestion process comprises a series of interlinked reactions evolving spatially as well as temporally in sequential and parallel steps. The conversion processes in anaerobic digestion processes can be divided into biochemical and physico-chemical reactions. Anaerobic stabilization processes are faced with limitations with respect to...
