It has been shown that the cultivation of catch crops may play an important role in the mitigation of CO2 emissions. A study on the importance of catch crops (in relation to the main crop) in carbon dioxide sequestration was conducted over the period of 2016-2018 under the soil and climatic conditions of the central Lublin region, Poland. Subsequently, ploughed-in catch crop biomass is a kind of ‘soil CO2 bank’. It was proven that in the case of successful catch crops one can expect carbon dioxide sequestration by these crop cultures to be at a level from 4 to 6 tons CO2 ha ·yr. The quantity of CO2 absorbed from the atmosphere by a catch crop is directly proportional to biomass yield produced by it. The following species, which are resilient to adverse weather conditions during seeding and initial plant growth, proved to be particularly useful in car...

However, by using these toxic metals, we disperse them around the planet, pollute it and, since they are not biodegradable, threaten future generation with unsafe environment. The other side of the problem is that they are nonrenewable resources and therefore current estimates suggest that, at present levels of consumption, there is enough lead for 58 years and mercury for 46 years, to mention just a few of the best known heavy metals. A role of these metals in the total environment is discussed in the paper.

Additionally, it can be used as a renewable source of energy, leading to depletion in CO2 emissions. The paper presents the results of estimations on the current and potential share of catch crop cultivation in climate change mitigation, in Poland, where the agricultural sector plays a significant economic role. The estimation of CO2 assimilation in biomass was performed on the basis of our own data on yields of commonly used catch crops, obtained in randomly selected 80 farms in Poland, and the content of carbon in the biomass. Calculation of energy potential of the biomass was conducted, assuming its conversion into biogas, on the basis of our own data on catch crop yields and the literature data on their biomethane potentials. The results have shown that catch crops in Poland, which are cultivated to an area of 1.177 mln ha sequestrate 6.85 mln t CO2 yr−1. However, considering the total a...

The sequestration of carbon dioxide in the biomass of plants, especially the ones which can be cultivated as catch crops is described. It was shown that the cultivation of catch crops may play an important role in the mitigation of CO2 emissions.

In this work, ultrasound/H2O2 digestion coupled with ferric oxide hydrate/biochar (HFO/biochar) adsorption process was performed to promote P dissolution, release, and recovery from biogas slurry. The results showed that the optimal total phosphorus release efficiency was achieved at an inorganic phosphorus/total phosphorus ratio of 95.0% at pH 4, 1mL of added H2O2, and ultrasonication for 30min. The P adsorption by the HFO/biochar followed pseudo second-order kinetics and was mainly controlled by chemical processes. The Langmuir-Freundlich model matched the experimental data best for P adsorption by HFO/biochar at 298 and 308K, whereas the Freundlich model matched best at 318K. The maximum amount of P adsorbed was 220mg/g. The process was endothermic, spontaneous, and showed an increase in disorder at the solid-liquid interface. The saturated adsorbed HFO/biochar continually releases P and is m...

The results of these studies were used in different purposes e.g. wastewater treatment plant (WWTP) efficiency assessment, modelling of WWTP working conditions as well as an influence of sanitation systems on VVWTP effectiveness. This paper presents the review of particular approaches to wastewater composition description, the basis of sewage composition changes modelling, the transformation of pollutants occurring in sanitation systems and its model description. The presented model of pollutants transformation may be utilized during the assessment of processes influencing the efficiency of wastewater treatment plant .

While developing new dependencies and demonstrating large transgressions against the present state, eco-energy investments affect redefinition of the identity of place, society and landscape. This paper discusses management of eco-energy anthropopressure with regard to the sustainable development of society and the economy. Projects of infrastructure modernisation related to construction of renewable energy sources should consider an assessment of anthropopressure trends, which facilitate definition of priorities in measures exemplified by subsequent investments, considering their economic, environmental and social aspects. The criteria of ecoenergy anthropopressure constitute the bases of analyses and guidelines when planning new undertakings. The positive trend of anthropopressure is a condition verifying the correctness of eco-energy engineering development. Application of enzymatic indicators enabling quantification of anthropogenic transformations, along with the ecological results of protective measures related to the generation of renewable energy allow for the long-term monitoring and identification of trends.
