Mowing sports turfs and grass surfaces generates waste biomass in the form of grass clippings. Biomass composting is commonly practiced generating nutrient-rich soil amendments. However, decomposing biomass can have adverse environmental effects such as gaseous emissions and nutrient leaching. This research investigated: (1) the kinetics of CO, CO2...

This article aimed to evaluate the visual and functional characteristics of intensively used football turf over 10 years, depending on the different areas of the game. The research was conducted on the football turf of the AZS Environmental Club in Wrocław (N: 51° 7′ 31′′ E:17° 4′ 14′′). High variability of the evaluated parameters was observed reg...

Wood bark is a by-product of the forestry industry with significant quantitative potential. Due to the higher heating value and hydrophobic character (dictated by the content of hydrophobic extracts in the chemical composition of the bark) facilitating long-term storage and transport, bark is considered a valuable material to be integrated into the...

Converting raw biomass into valuable products protects the environment, improves economics, and helps tackle climate change by cutting resource demand and waste production. Thermochemical treatment is a common method for producing biochars, hydrochars and torrefcates from biomass and organic wastes, which can also generate dioxins and furans and co...

Various techniques are implemented to reduce odor emission due to their potential multi-source nature. One modern approach is the use of thermochemically processed biomass to eliminate odors. Compared with raw biomass, processed biomass is characterized by greater porosity and an expanded specific surface. In these laboratory experiments, adsorptio...

Mowing grass surfaces is the most energy-consuming activity in the maintenance of golf courses, contributing to GHG emissions. Additionally, as a result of the need to maintain the height of the turf at an appropriate level, a significant amount of biomass residues is generated, which requires proper disposal. The goal of this work concerns the det...

The research carried out at the Experimental Station of the University of Agriculture in Krakow aimed to assess the utility value of the turf of a lawn sown with the “Super Trawnik” lawn mixture. The experimental factor was spraying the turf with an amino acid preparation in the form of the AMINO ULTRA Fe-20 fertilizer in three doses: 0.3, 0.5, and...

Odors are considered as one of the most important environmental problems that may adversely influence the quality of life of people affected by their interaction. Due to the multiple sources of emissions, combined with the abundance of chemical compounds classified odor nuisance, new methods of reducing odor emissions are sought while maintaining e...

Soil and air pollution are main problems posing a serious threat to human health. Traditional physical and chemical soil remediation methods affect the soil ecosystem and are rather costly. Since the main purpose of soil remediation is not only to remove pollutants but also to restore soil health, the method of phytoremediation is becoming extremel...

Due to the need to diversify energy sources and transform the energy system and its decarbonization, new paths for obtaining raw materials are being sought. One of the potential options is to increase the use of grasses’ share in bioenergy production, which has a significant area potential. However, the diversified chemical composition of grasses a...

A large portion of food loss and waste (FSL) is comprised of seeds and stones. Exotic fruits such as mangoes, lychees and avocados, in which the seeds account for a significant part of the weight and volume of the entire product, are most affected by this problem. The seeds contain a large quantity of polyphenols and essential nutrients, which make...

The selection of grass mixtures with appropriate visual and functional parameters for sowing football felds is a key element in shaping the sports infrastructure, ensuring the spectacularity of a match and comfort for players. The aim of the research was to investigate the properties of lawn grass mixtures and their suitability for football pitches...

The aim of the experiment was to determine the effect of species composition on the rigidity and elasticity of football pitch turf. The research was conducted for three years on micro-plots of 1 m 2 at the Toya Golf & Country Club (51°20′E, 17°07′N). The variable was M1-M12 lawn grass mixtures with different species composition. Commercially availa...

The mowing of sports fields generates a significant amount of waste biomass which requires appropriate management. On the largest scale, this problem affects golf courses with a grass surface area of up to 100 ha. Currently, the main directions for grass clippings management include composting, grass cycling, and waste. A certain alternative may be...

Due to the tendency for excessive moisture adsorption by raw, unprocessed biomass, various methods of biomass valorization are in use, allowing for the improvement of physical– chemical biomass properties, including hydrophobicity. One of the methods is torrefaction, which changes the hydrophilic properties of the biomass to hydrophobic. Therefore,...

Catering trailers are small gastronomic points that sell food in unusual, remote locations where access to the power grid is difficult or impossible. Therefore, owners are forced to use a separate energy source to ensure continuity of operation of specialized equipment. The article presents the concept of a photovoltaic installation with an energy...

The aim of this research was to determine the effect of micronutrients and a fungicide on the germination of perennial ryegrass seeds. The experiment was conducted between 2016 and 2018 in Blizocin (51°22′ N, 17°09′ E), Poland. The first experimental factor was InnoFert Mikro, a micronutrient fertilizer used at doses of 0.5 and 1 L∙ha−1, while the...

Briquetting is one of the recommended biomass agglomeration processes. The material subjected to briquetting gains valuable functional features related to higher energy density, appropriate moisture content, and increased bulk density. However, the briquettes need high mechanical durability to maintain high quality during transportation, loading, a...

: The main sources of greenhouse gas emissions and air pollution from the transport sector are diesel- and gasoline-powered passenger cars. The combustion of large amounts of conventional fuels by cars contributes to a significant release of various compounds into the atmosphere, such as solid particles, nitrogen oxides, carbon monoxide, and carbon...
