Currently, there are different remediation technologies for contaminated soils, but the selection of best technology must be not only treatment efficiency also energy consumption (costs) during its application. This paper is focused on assessing related to electrochemical polluted soil with petroleum hydrocarbons. In framework a research project, two types experiments were conducted using that was artificially diesel fuel at same level contamination. The experimental conditions considered...

This study aims to obtain the information about thermal characteristics of Passive House University POLITEHNICA from Bucharest, Romania. Modelling a house by using method networks is way find out specific reaction variable outdoor conditions. Heating, ventilation and air conditioning (HVAC) systems including their control have synchronise with expressed heat consumption. The results this give necessary define, calibrate optimise an adequate HVAC system good prediction changing outer...

Abstract In 2011, as a result of the inventory conducted at national level, The Ministry Of Environment concluded that largest number contaminated sites with hydrocarbons are due to petroleum products distribution (nearly 400 sites), followed by extraction (about 310 sites). So, soil contamination liquid resulting from many industrial activities became an important issue environment protection. Unfortunately not all local governments have provided list sites, which means there is possibility...

Romania ranks among top countries in Europe with the lowest amount of waste produced, 261 kg/capita/year, compared to northern countries, that generate almost double waste. However, it performs poorly recycling sector and management although significant amounts money have been invested over last 10 years. The paper presents 2 pilot projects regarding implementation a collection system two small communities Northern agreed adopt implement Zero Waste Strategy towards Circular Economy. After...

Within the current research, GORE™ COVER composting system was tested for treating organic waste by aerobic digestion performed in closed installation, equipped with a positive aeration and semipermeable membrane. After 42 days (with 2 intermediate returns intensive decomposition phase of 28 days) respectively after 14 (so, second phase), 4 samples were collected. Performing specific laboratory analyzes, initial characterization mixture (sludge from wastewater treatment plant wood sawdust)...

Contaminated soils with toxic and persistent pollutants pose significant potential hazards to the environment human health. The problem of polluted choosing most appropriate remediation strategy is a current concern throughout world. As result industrial activities related energy sector (mainly from extractive industry), contaminants interest at national international level in terms contaminated sites are petroleum hydrocarbons. In this context, main aim present research was evaluate degree...

In the last decade, Romania began a reorganization process in municipal solid waste (MSW) sector considering new EU principles regarding MSW prevention, reuse and recycling before final disposal. The paper present results of comparison three alternative scenarios for energy recovery (ER) from landfilling, separate collection, mechanical-biological treatment, thermal treatment waste-to-energy. For evaluation each scenario mass, environmental balances is reported.

Airborne biological particles are made by bacteria, viruses, fungi, pollen, dust mites and other living organisms. Between the airborne contaminants, sampling of viruses is most difficult. This technical challenge has real consequences both in limiting studies on aerobiology viral diseases, making possible, at least for now, to establish Standards Acceptable Bioaerosol Exposure Limits case viruses. The circumstances uncertainties which we from end 2019, have demonstrated once again, need...
