Solid wastes from the enzyme production as a potential biosorbent to treat colored effluents containing crystal violet dye

Sugarcane bagasse, a largely available waste worldwide, was submitted to solid-state fermentation (SSF) using the fungus Metarhizium anisopliae, aiming to produce enzymes. The solid waste generated from SSF was tested as an alternative biosorbent to treat colored effluents containing crystal violet (CV) dye. The biosorbent, here named BW (bagasse waste), was characterized, and experimental tests were performed to verify the influence of pH and dosage on the CV biosorption. Isotherms and biosorption kinetics were performed, and the biosorption thermodynamic parameters were determined. The potential of BW was also evaluated for the treatment of a simulated textile effluent. The maximum biosorption capacity was 131.2 mg g−1 at 328 K, and the Liu was the most appropriate model to represent equilibrium data. The biosorption was spontaneous and endothermic. The use of BW in the simulated effluent showed that it is an efficient material, reaching color removal values of 85%. Therefore, the sugarcane bagasse generated from SSF can be considered a potential biosorbent to remove CV from textile effluents. This finding is relevant from the total environment viewpoint, since, at the same time, SSF generates enzymes and a solid waste, which in turn can be used as biosorbent to treat colored effluents

Trabalhos científicos em eventos universitários e sua contribuição para os Objetivos do Desenvolvimento Sustentável

Universidades são ambientes propícios para a discussão de temas relacionados à sustentabilidade, incluindo a Agenda 2030 e os Objetivos de Desenvolvimento Sustentável (ODS). Apesar do reconhecimento da importância de pesquisas universitárias sobre os ODS, muitos estudos contribuem para a Agenda 2030 sem reconhecer formalmente esta contribuição. Neste contexto, este artigo visa analisar os trabalhos publicados entre 2015 e 2019 em um importante evento acadêmico da Universidade de Passo Fundo e classificá-los de acordo com sua contribuição para os ODS. A metodologia de análise de conteúdo foi empregada, com análise dos títulos e/ou texto completo dos trabalhos, disponíveis do website da instituição. Os resultados obtidos mostram que a porcentagem de trabalhos que possuem relação com os ODS aumentou nos últimos anos, sendo o ano de 2019 o que mais possui trabalhos relacionados com os ODS e as áreas Ciências da Saúde e Ciências Exatas abordaram mais os ODS em suas publicações.Universities are conducive environments for discussing topics related to sustainability, including the 2030 Agenda and the Sustainable Development Goals (SDGs). Despite the recognition of the importance of university research on the SDGs, many studies contribute to Agenda 2030 without formally recognizing this contribution. In this context, this paper aims to analyze the academic research published between 2015 and 2019 in an important academic event at the University of Passo Fundo and to classify them according to their contribution to the SDGs. The content analysis methodology was used, with analysis of the titles and/or full text of the works, available on the institution's website. The results obtained show that the percentage of researches related to the SDGs has increased in recent years, and 2019 was the year with the highest number of works related to the SDGs also, the Health Sciences and Exact Sciences areas most addressed the SDGs in their publications

Building university capabilities to respond to climate change through participatory action research: towards a comparative analytical framework

This paper aims to explore how the principles of participatory action research (PAR) articulate with questions of climate justice. Drawing on three qualitative case studies in Brazil, Fiji and Kenya, the paper explores university institutional capabilities, asking how the principles of mobilising PAR to support transformative outcomes can further climate justice. The paper argues that for participatory action research to become a pathway to build universities’ capabilities, key considerations are needed. PAR needs to: (a) move beyond change in individual behaviour to respond to climate change and affect institutional norms, procedures and practices; (b) recognise and partner with marginalised groups whose voice and experiences are at the periphery of climate debate, enabling reciprocal flows of impact and knowledge between universities and wider societies; and (c) foster “relationships of equivalence” with actors within as well as outside university to influence university governance and wider climate-related policy-making processes
