The engine was fueled with second-generation biodiesel obtained from used frying oils (classified as waste) and first-generation biodiesel produced from rapeseed oil as well as, comparatively, diesel fuel. Tests were conducted on a dynamometer bench at a variable load and a variable engine speed. The levels of PM and NO emissions in the exhaust gas were determined. The study showed significant environmental benefits of using firstand second-generation biodiesel to power the engine due to the level of PM emissions. The PM content, when burning ester biofuel compared to diesel fuel, was reduced by 45-70% on average under the speed and load conditions implemented. As for the concentration of nitrogen oxide in the exhaust gas, no clear trend of change was shown for the biodiesel in relation to the diesel fuel. The level of NO emissions in the range of full-power characteristics was found to be lower for both tested biofuels compared to diesel fuel at lower engine speeds by an average of 7-8%, while in the range of a higher rotation speed, the NO content in the exhaust gases was higher for the tested biofuels compared to diesel oil by an average of 4-5%. The realized engine performance tests, moreover, showed an unfavorable effect of the biodiesel on the engine energy parameters. In the case of biofuels, this was by more than 4% compared to diesel fuel.

The selected indicators of the exploited agricultural tractor were balanced and compared in two one-month agricultural periods. During the first research period the tractor worked as a transport vehicle, and during the second period − took part in post-harvest crops. The results were shown in the form of time courses of chosen parameters as well as one-and two-dimensional frequency characteristics. Essential participation of idle running working time of the engine was found, which matched the distribution of power and showed that it is not optimally utilized while the tractor is working on the studied farm.

Chromatographic content and basic rheological parameters of the substances under research were also analyzed. Liquid wastes, tar, and mixture of tar and engine oil were introduced to the soil in the amount of 100 mg kg −1 DM soil. Based on the conducted research, it was ascertained that the changes in the number and activity of soil microorganisms were determined by the type of waste and its dose. Individual groups of microorganisms showed different sensitivity to the presence of pollution; however, the impact of tar and engine oil mixture was generally more disadvantageous. Presence of contaminants in the soil limited the growth of roots and aboveground parts of spring barley, especially when the dose was 10,000 mg kg −1 DM soil. The unfavorable impact of waste on photosynthesis efficiency on assimilation pigment synthesis and water content in the plant was recorded.

On the basis of the statistical evaluation of the test results, it was shown that there is a significant relationship between the initial condition of microgeometry of the rollers as described by values of average arithmetic deviation of the profile from the medium line (parameter Ra) and the measure of linear use of the bush material of the sample.

Their properties have a significant impact on the proper functioning of the engine supply system and the wear of its components. Changes in the performance of biofuel functionality may already occur during storage. Therefore, the present study aimed to evaluate changes in selected rheological and tribological parameters of higher fatty acid esters depending on the time and method of their storage by considering different types of substrates used for their production. The presence of possible microbiological contamination, which may affect the examined parameters of biofuels, was also analyzed. The dynamic viscosity of the biofuels tested changed depending on the substrate used. The biofuel produced from waste oil had the highest viscosity. Tribological studies show that both the linear wear of samples and the friction moment were higher after the storage period. The acid number of the esters did not exceed the permissible value recommended by the standard. The type of raw material used for the production of biodiesel and the conditions of its storage affected biodeterioration, proved by the growth of microorganisms. The highest number of microorganisms was recorded in biofuels prepared from waste oil.

This assessment was made on the basis of the technical analysis and elemental composition: C, H, N, S. 14 different types of wood pellets available on the market were tested, each of them came from a different producer. In addition, an attempt was made to assess the content of organic matter in the tested pellets on the basis of methane fermentation. The innovation in the presented work is the use of biomethane production potential assessment for pellet fuel, which until now has been practised only in the case of substrates for biogas production. The parameters characterizing the tested pellets in energy terms did not differ significantly. The high calorific value and low ash and sulfur content indicated that the output biomass was of good quality. The differences in the production potential of biomethane of the tested pellets do not allow to state unequivocally that methane fermentation can be used to assess the quality of pellets and their contents of organic matter. However, the large BMP differences obtained for individual pellets suggest that some pellets may contain impurities inhibiting the methane fermentation process.

The present study was conducted to demonstrate the potential of pea (Pisum sativum L. spp. sativum) cultivar Blauwschokker to phytostimulate biodiesel degradation in an agricultural soil, considering the influence of biological remediation on selected physiological parameters of plants and the amount and activity of soil microflora. Biodiesel was spiked into soil in dose of 50 g kg −1 of dry mass soil. The results of the study showed that the rate of biodiesel degradation in the vegetated soil was higher than that occurring by natural attenuation. At the same time, biodiesel showed a positive effect on the growth, development, and activity of soil bacteria and fungi. Moreover, the obtained results showed an improvement in physiological parameters of plants, including an increase in chlorophyll a and total chlorophyll content and higher relative water content in leaves in the presence of biodiesel.
