“…A local farmer collects chicken manure from the producer in exchange for straw for bedding. As straw is traded but not directly purchased, the proportion of its renewable fraction (0.107) was determined using literature data (Kuczuk, 2016;Sun et al, 2021). Annual inflows of local renewable emergy include solar emergy, wind emergy and water from precipitation.…”

Poultry meat consumption is a significant element in Poland's overall food consumption. Economic considerations mean that both nationally and globally, conventional intensive rearing dominates. Nevertheless, environmental and health aspects or the will to treat animals humanely make pro-environmental rearing systems increasingly common. The purpose of this article is an environmental analysis of an example farm engaged in intensive rearing of slaughtered poultry (so-called baseline production). For the analysed production, the following scenarios of changes were proposed: (a) conventional rearing based on the use of own fodder, and (b) organic rearing using free range and own organic fodder. An emergy approach was applied in this analysis. Comparison of different production systems using emergy analysis made it possible to show the scale of environmental resource commitment for baseline and scenario-based productions, and to determine the amount of renewable and non-renewable emergy consumed per unit of production. Through the use of selected emergy indicators, e.g.: Environmental Loading Ratio (ELR), Emergy Yield Ratio (EYR), the environmental impact for each case was determined. For the ecological system scenario, the need to change production parameters (stocking rate, maximum poultry house area, free range) was taken into account. The results of the emergy-based indicators showed that the baseline production places the greatest burden on the environment and is the least sustainable. The organic system is the opposite; however, due to production limitations and the lower production efficiency achieved, it may not be economically viable to orient a farm exclusively to the organic system. In an environmental assessment, the information obtained can provide valuable guidance to agricultural producers. They can help make informed decisions on natural resource management to achieve environmental security. The results are also important for political decision-makers in creating policies for more sustainable agricultural production. The results obtained are discussed, pointing out the importance of the analysis used mainly from an environmental point of view.

“…In the field of straw recycling, experts and scholars have performed many studies and made these systems work better. Sun et al 30,31 took the straw recycling company in Sheqi County, Nanyang City as an example, and combined economic analysis and emergy indicators to effectively solve problems in the logistics of the collection, transportation and storage of straw power generation. Singh et al 32 showed that the economy of power generation system can be improved with a biomass management system.…”

The current study took Henan Wufeng New Energy Science Technology Co. Ltd as an example to investigate a large‐scale steam heating system with biomass briquette fuel in Henan, China. Drawn on several months of field research, the economic cost and greenhouse gas emissions for peanut shell straw collection, transportation, storage and burning at Henan Wufeng New Energy Science Technology Co. Ltd were analyzed in 2021. Moreover, the economic cost and greenhouse gas emissions were used as evaluation indicators to evaluate the biomass molding fuel supply system systemically. Economic analysis shows that the steam heating system can make a profit of 1.72 × 106 yuan per year, and the input–output ratio (ROI) is 93.87%, which is much higher than the benchmark input–output ratio (30%). The very high ROI indicates that the system is difficult to operate in an economically feasible manner. Greenhouse gas emission analysis demonstrates that at the same heating level, the system can save 4.42 × 107 kg of standard coal and reduce the emissions of greenhouse gases to the environment by 1.25 × 105 tCO2eq, which has significant environmental benefits. Taken together, the government should adopt effective economic policies to promote the efficient use of biomass straw and support biomass straw recycling and heating enterprises. © 2022 Society of Chemical Industry and John Wiley & Sons, Ltd.

The global expansion of the bioenergy industry raises concerns, emphasizing the need for careful evaluation and sustainable management. To facilitate this, life cycle assessments beyond greenhouse gas emissions and energy balance are essential, along with the standardization of assessment methodologies to enable meaningful comparisons. Here, we review life cycle assessment, chemical aspects, and policy implication of bioenergy production. We discuss life cycle assessment in terms of concepts, methods, impacts, greenhouse gases, land use, water consumption, bioethanol, biodiesel, biogas, and techno-economic analysis. Chemical aspects comprise reaction processes and means to improve efficiency. Concerning policies, tools, and frameworks that encourage sustainable energy production are presented. We found that carbon dioxide removal ranges from 45 to 99% in various bioenergy processes. The review also emphasizes the importance of chemistry in advancing sustainable bioenergy production for a more sustainable and secure energy future.
