“…The treatment of organic waste from 323 university restaurants is commonly used as fertilizer for the campuses' green spaces (de 324 Castro and Jabbour, 2013;Eatmon et al, 2015;Jain and Pant, 2010;Najad et al, 2018;325 Nandhivarman et al, 2015;Reidy et al, 2015). The "waste-to-energy" principle is also 326 conveyed, with examples of electricity or biogas generation from waste sources (Bauer, 2018;327 Helling, 2018;Nandhivarman et al, 2015;Tu et al, 2015). A significant reduction in 328 petroleum gas use (Nandhivarman et al, 2015) and CO 2 emissions (Tu et al, 2015) is 329 reported.…”

“…The work of Tu, Zhu & McAvoy (2015) the work of the authors aims to analyze the implementation of three projects for the transformation of waste at the University of Cincinnati, improving sustainability, one of which is the food waste for biogas, indicating a result capable of "replacing 12.767 m3 of natural gas per year of 146 tons of food waste" and having a return time of the invested value of 74 months and the minimization of greenhouse gases was 11.36 tons of CO2 per year.…”

Due to increased consumption and inadequate waste disposal, causing environmental damage for present and future generations, it is necessary to change from a linear economy to a circular economy, where what is “garbage” in a production process becomes matter press on the other. This article aims to identify strategies used for the management of food waste in university restaurants, in Brazilian public higher education institutions. A sample of 19 federal universities in southeastern Brazil was chosen. The data on the management of food waste residues from these institutions were collected in the Institutional Development Plans, Sustainable Logistics Plans and the Institutions website. The research showed that despite 73.68% of the sample talking about waste in their Institutional Development Plan and or Sustainable Logistics Plan, only three universities disclose on their websites information about treatments and / or research carried out by them in the scope of waste management food. The data indicate the need to weave institutional policies and strategies for the theme.

Background: The generation of clean and affordable energy by 2030 is a challenging task, necessitating the integration of renewable energy sources to reduce greenhouse gas emissions associated with coal, crude oil, and natural gas. This study examines the optimization and performance analysis of a hybrid microgrid for a university campus as a potential solution to achieve this goal. The primary objective is to decrease the cost of energy and reduce CO2 emissions on the campus using a hybrid approach. Results: The Howard college campus of the University of KwaZulu Natal (UKZN) was used as a case study, with meteorological data obtained from NASA and real hourly electrical load data for 2019 from the university smart meters. HOMER, an optimization software, was employed to model and simulate the case study. The results demonstrated significant savings of R15.7 million (approximately $1 million) in annual utility bills, a 51% reduction in CO2 emissions, a return on investment of 20%, and a payback period of 4 years. Conclusions: The study's findings suggest that universities can become self-sustaining during load shedding periods, as recently experienced in South Africa. The implementation of a hybrid microgrid system on a university campus offers considerable economic and environmental benefits, providing a potential blueprint for other large institutions seeking to achieve similar sustainability goals.
