As nations strive toward achieving sustainability and reducing reliance on fossil fuels, biomass has emerged as an indispensable component of worldwide energy portfolios. Biomass, derived from organic materials such as plants, agricultural residues, forestry byproducts, and organic waste, is a renewable energy source and abundant resource with sign...

Urban development is not a process of even and planned progression on residential-industrial sites. Enclaves of high-standard space separate degraded and abandoned areas after industrial use has ended. The idea of the compact city is challenged by the need to search for niches for possible development and even to respond to crisis situations. Chang...

This study evaluates the quality of 30 biomass pellets sold for residential use in Poland. It provides data on their physical, chemical, and petrographic properties and compares them to existing standards and the information provided by the fuel producers. The results reveal considerable variations in the quality of the pellets and show that some o...

Organised bathing areas located within leisure facilities, in addition to the function typical of their purpose, allow in most cases the use of their own barbecue facilities. This type of cooking of food before consumption is very popular during leisure time at the waterfront. However, cooking food on a barbecue produces fumes emitted from both the...

Considering global market trends and environmental climate, increased biomass use for energy is expected to continue. As more diverse materials are being utilized to manufacture solid biomass fuels, it is critical to implement quality assessment methods to thoroughly test these fuels. One such method is reflected light microscopy, which has the pot...

With interest rising in biomass use, biomass gasification has the potential to become an imperative mechanism to deliver clean conversion of various types of solid biomass to gas. But as biomass gasification attracts growing interest, it is important to focus not only on the technological feasibility but also fully understand its environmental impa...

Concerns about climate change, energy security, and the diversification of energy supplies have made renewable resources increasingly more attractive and important sources of energy. As this interest rises, biomass utilization has the potential to become one of the pillars of the future energy portfolio. It is, therefore, critical to assure that so...

Processes associated with surface mining promote the creation of artificial water reservoirs. In most cases, these post mining reservoirs can be adapted for recreational purposes after slight modifications. The authors analyzed the characteristics of inland reservoirs created as a result of opencast mining of diverse types of deposits in terms of t...

Abandoned mine lands are a common element of the contemporary landscape. In administrative practice, they are rated low, yet they are of interest to informal users and scientific and cultural communities. The aim of the research was to identify the possibilities of using qualitative research methods, applied in architecture, to create friendly, urb...

As concerns about climate change and sustainability rise, biomass utilization has a potential to become one of the pillars of the future energy market. It is therefore critical to assure that solid biomass fuels are of the highest quality and do not contribute to avoidable air pollution. Our research has shown that petrographic analysis of solid bi...

The quality check of grilling wood pellets should be of a critical importance as smoke from their combustion has a direct contact with food, impacts human safety, and pollutes the atmosphere. Therefore, the main purpose of this study is to investigate the purity of grilling wood pellets and chips available on the market, analyze the properties of t...

This “Atlas of Charcoal-Based Grilling Fuel Components” features compilation of over 620 microscopic images taken between 2019 and 2021 while our team was improving methodology of using reflected light microscopy in identification of charcoal-based grilling fuels constituents. These photomicrographs provide documentation of the composition of the f...

Thirty-one batches of commercial charcoal from various regions of Poland and Germany were tested for the presence of 20 toxic elements and polycyclic aromatic hydrocarbons (PAHs) using gas chromatography-mass spectrometry (GC-MS). Elements that are toxic to living organisms were determined using atomic absorption spectroscopy (AAS). They were class...

Concerns about climate change, energy security, and the diversification of energy supplies have made renewable resources increasingly more attractive and important sources of energy. As interest grows, bioenergy (energy from bio-based sources) is becoming more environmentally friendly and economically viable and has started to play a more prominent...

Numerous studies have been conducted to assess air pollution and human health risks arising from exposure to outdoor cooking, but limited standards have been implemented around the world to assure fuel quality. While charcoal briquettes and lumps are a popular fuel choice for grilling, almost no data specifying their properties are available to con...

As the interest in the renewable resources has been increasing worldwide, the wood pellet sector has the potential to become a mainstream fuel of the future in the heat market. This development is especially noted in the European Union countries which consumed 50 % of global wood pellets in 2018. While only about 2 % of the United States energy con...

Wood pellets, commonly referred to as biomass fuel, are increasingly used in heating and district heating in the European Union countries, including Poland. Their use in class 5 and/or Ecodesign boilers enables an individual consumer to use energy from renewable sources, reduce the environmental burden by reducing the emission of harmful compounds,...

In the first years of the twenty-first century, a growing interest in investments in the Polish energy sector can be observed. This is due to the fact that Polish energy producers need to adapt to the European Union standards and due to the growing demand for services provided by the power sector. Meeting the increasingly more stringent emission st...
