Biogas production is the most important and promising alternative for replacing fossil fuels in an environmentally friendly manner. Along with the many renewable energy sources available, biogas production occupies an irreplaceable position due to the undeniable availability of biomass and the need to manage agro-commercial waste. The article reviews the current state of technology used in the production of biogas for selected European examples in terms of methane fermentation efficiency and actual energy production. The novelty of the article is its description of innovative trends that have great potential to play an important role in this field in the near future. The development of the biogas industry in Europe is evident, although the dynamics vary from country to country. Different models are presented, which are based on the different types of feedstock used for biogas production and the proportion of substrates used in co-digesters. Of course, Germany is the undisputed pioneer in the use of this renewable energy source. Nevertheless, the efforts to improve energy self-reliance and environmental impacts are reflected in the growing number of operational biogas plants in other European countries, which provides hope for rapid progress toward the complete abolition of the conventional exploitation of fossil fuels.

The rapid analytical method was developed in response to increasing concern over the environmental impact of azoles (sterol biosynthesis inhibitors) and neonicotinoids (nicotinic acetylcholine receptor site). These chemicals are commonly used to protect fruit and vegetables crops against fungi...

The purpose of the work was to determine the efficiency of domestic wastewater treatment contaminated with a mixture of pesticides at varying deposit load. The efficiency of purification in the case of eight pesticides equaled 99.8%, and the removal effect of azoxystrobin reached 93%, while that of thiachloprid - 96%. The constructed wetland ensured high removal of organic matter expressed as BOD and COD, as well as reduction in the concentration of nitrogen and phosphorus compounds. Studies showed a clear impact of the deposit load on the effectiveness of pesticide removal, BOD and COD parameters, total phosphorus, and total nitrogen.
