Agricultural wastes (AWs) generated from farming practices pose environmental threats if not properly disposed of or recycled through biological processes. Mushroom production presents a sustainable solution by converting AWs into highly nutritious food while mitigating environmental pollution. However, there is a lack of comprehensive frameworks to assist farmers and businesses in visually understanding the essential elements of a circular bioeconomy, such as mushroom production’s potential interconnections and impacts on value creation. This study theoretically elaborates on a framework using the Business Model Canvas to structure mushroom production across the following key business areas: customers, supply chains, infrastructure, and economic viability. We discuss these aspects within the context of recent studies. In addition to guiding farmers and businesses, we align mushroom production with Sustainable Development Goals (SDGs) within the supply chain, underscoring the importance of developing business models to foster the growth of circular economies and sustainability.

Hop (Humulus lupulus L.) is a crucial ingredient in beer, valued for its bitter acids and essential oils. Traditionally cultivated in temperate regions, hop production faces challenges from climate change, necessitating the exploration of new growing areas. This study evaluated the chemical quality of hop varieties grown in Brazil’s subtropical conditions to assess their suitability for brewing. Seven hop varieties (Cascade, Centennial, Columbus, Chinook, Comet, Fuggle, and Nugget) were analyzed for total α- and β-acids and essential oil composition. Bitter acids were quantified by spectrophotometric analysis, and volatile compounds were identified using gas chromatography coupled to mass spectrometry (GC-MS). Comet exhibited the highest a-acid level (10.54%), indicating strong bittering potential. Essential oil analysis revealed β-myrcene, (E)-caryophyllene, and α-humulene as predominant compounds. Centennial showed a distinct (E)-β-farnesene profile, a characteristic of noble hops. All varieties contained α- and β-selinene, suggesting a common metabolic pattern. The results indicate that Brazil has the potential to produce high-quality hops with suitable chemical profiles for brewing. As traditional hop-growing regions face climate-related challenges, hops cultivated in Brazil may offer a viable alternative for achieving the desired chemical composition required by the brewing industry.

We investigated whether highly available organic residues in Brazil can be used as substrates for the production of the oyster mushroom Pleurotus ostreatus, instead of the conventional cultivation using the eucalyptus sawdust substrate. We assessed the mushroom yield on 13 substrates, of which 12 were formulated with different concentrations of organic residues and one with pure eucalyptus sawdust, and verified whether the raw material used in the substrate formula and the concentration of such alternative residues influenced their biological efficiencies. Substrates containing eucalyptus bark resulted in higher mushroom yield than those containing eucalyptus sawdust, which generally resulted in similar mushroom yield to the remaining formulas. Moreover, the raw material and the concentration of each residue affected the biological efficiency of the substrates. We show that the conventional substrate for P. ostreatus can be replaced by substrates easily accessible to producers without loss in productivity. Furthermore, that the concentration of these mixtures affects the mushroom productivity and should be considered when formulating the growth medium.

: More than 1.5 billion people are infected by soil-transmitted helminths (STHs) worldwide, comprising one of the world’s most serious public health problems. School-age children are the most affected as a result of precarious hygienic habits, especially in economically poor areas that lack appropriate sanitation. Therefore, this study aimed to evaluate a didactic method via a health education approach as a complement to the school curriculum of the sixth-grade students of public schools, distributed among six cities in the state of São Paulo, Brazil. For this, a didactic booklet was elaborated with educational explanatory activities about worms, their life cycle, and how to avoid infections. The intervention was measured by the change caused by knowledge, attitude, and practice (KAP), in students before and after using the notebook, through a questionnaire with high validity and internal consistency. Schools were assigned randomly into intervention and control groups, receiving both the didactic material and the questionnaires, versus the questionnaires only, respectively. The results were submitted to an analysis of covariance that revealed a significant difference pre- and postintervention for knowledge (P < 0.001), with greater means (0.54) compared with the control group (0.44); attitude (P < 0.005), with respective means of 0.56 versus 0.48; and practice (P < 0.001), with means of 0.75 versus 0.57. These findings set the didactic material as a potential tool to complement the school curriculum through KAP without disrupting the teaching system, in addition to assisting teachers in health education at schools aiming to prevent children’s infections by STHs.

Hops ( Humulus lupulus L.) have been cultivated in Brazil, the world's third‐largest beer producer, to meet the growing demand of its expanding brewing industry. Despite advances in agricultural practices, research on the sustainability of tropicalizing hop production remains limited. This study evaluates the social and environmental impacts of hop production in 10 reference farms across the Brazilian states of Alagoas, Goiás, and São Paulo using the Ambitec‐Agro tool. This tool assesses the impacts generated by technological innovations adopted in rural environments through change coefficients incorporated into multicriteria indicators, with weights assigned based on the spatial scale of impact occurrence within the farms. Impact indices were calculated across seven aspects: technology efficiency, environmental quality, customer respect, employment, income, health, and management and governance. These aspects were integrated into 27 criteria and 148 indicators. The results indicate positive outcomes across most criteria, with occasional temporary negative results related to energy consumption; use of agricultural inputs and raw materials; water consumption; occupational safety and health; and atmospheric emissions. To address these issues, farmers have invested in solar panels to reduce energy consumption and support other crops, implemented fertigation to improve water and input efficiency, promoted the safe use of protective equipment, and implemented green manure to store carbon. Additionally, hop production has contributed to economic growth by generating income, creating jobs, and promoting gender and generational equality, while also fostering the production of a high‐added‐value product for the Brazilian agroindustry.
