This paper treats about the problem of nitrogen oxides formation in the process of natural gas combustion. The analysis of the influence of selected combustion parameters on the concentration of NO, N2O and NO2 in the combustion products was done. From many factors determining NOx formation two...

This paper is a critical analysis of the sustainable development issue, especially in term of environmental sphere. Author tries to prove that even if well-off countries spend more and more money to protect environment, however the real effects of their actions are relatively week. The current...

The article evaluates various types of heat source used for heating and ventilation in a typical singlefamily house. Additionally, the paper presents the ecological analysis of the proposed solutions according to The National Centre for Emissions Management (KOBiZE) standards. The analysis was...

This paper presents an empirical verification of the demand price elasticity for piped water in major cities in Poland – it was the main goal of the research. The information concerning the demand reaction to price changes is substantial for sustainable urban water demand. Any prediction of...

Distilleries, in addition to ethanol, produced vinasse which is hazardous for the environment. Sugar beet molasses vinasse (BMV) is the most problematic waste from distilleries because of the coloured compounds contained therein. Traditional methods of the removal of the pollutant load from the...

The technologies of thermal processing of biomass, biowaste or sewage sludge into biochar as well as its potential use in the industry, power industry, housebuilding industry, agriculture or environmental protection attract growing attention. The multi-faceted, unique properties of biochar make...

The work attempts to comprehend why littering is so extensive and, with the use of several findings provided in Gary S. Becker's article entitled “Crime and Punishment: An Economic Approach”, to explain why under current conditions more waste discarded in the environment can be expected. The...

The EU economy is currently losing a significant amount of potential secondary raw materials which are present in waste streams (particular numerical data are presented in the paper). In the total amount of generated waste, the share of Coal Combustion Products (CCPs) and Coal Mining Products...

The implementation of Water Framework Directive, speaking about the need to achieve good water status, and thus the corresponding sewage treatment caused the problem of waste water management has become a very important starting from the municipal level, through the national and the European...

Hydrocarbons belong to the compounds most occurring in surface waters and groundwater. The presence of petroleum compounds in such waters brings significant changes to their physicochemical and organoleptic characteristics even at very low concentrations, like 0.01 g/m3. Petroleum compounds...
