Special Issue Information

Dear Colleagues,

The production and burning of fossil fuels have been identified as the source of greenhouse gas emissions, which negatively influences the ecosystem. Since the origins of carbon emissions are now known, extensive research has been conducted to reduce climate change, which has turned into a global nightmare. With the increasing awareness of global warming, scientists have looked for techniques to produce fuel from naturally sourced materials with environmentally friendly production and application processes. Although several biofuels have been produced, the drawback lies in the entire process' output (yield). Significantly, studies have shown that incorporating catalysts or additives has a dominant influence on biofuel production yield. This development has opened new pathways in catalytic processes by giving researchers unmatched control over critical characteristics, including size, shape, content, and morphology. Although nanotechnology is not new in chemistry and biofuel production, its constant advancement has brought it to the forefront of scientific discussion, making it the most popular buzzword of the decade. Despite rigorous studies in this research area, several untapped bio-based catalysts and their incorporation techniques are needed. Therefore, this Special Issue will focus on incorporating naturally sourced catalysts and new techniques, as well as improving biofuel production via naturally sourced catalyst incorporation.

In the past decade, agricultural biogas plants have become one of the key tools driving the energy transition in rural areas. Nevertheless, their development in Poland still lags behind that in Western European countries, suggesting the existence of barriers that go beyond technological or regulatory issues. This study aims to examine how Polish farmers perceive the risks and expected benefits associated with investing in biogas plants and which of these perceptions influence their willingness to invest. The research was conducted in the second quarter of 2025 among farmers planning to build micro biogas plants as well as owners of existing biogas facilities. Geographic Information System (GIS) tools were also used in selecting respondents and identifying potential investment sites, helping to pinpoint areas with favorable spatial and environmental conditions. The findings show that both current and prospective biogas plant operators view complex legal requirements, social risk, and financial uncertainty as the main obstacles. However, both groups are primarily motivated by the desire for on-farm energy self-sufficiency and the environmental benefits of improved agricultural waste management. Owners of operational installations—particularly small and medium-sized ones—tend to rate all categories of risk significantly lower than prospective investors, suggesting that practical experience and knowledge-sharing can effectively alleviate perceived risks related to renewable energy investments.
