Abstract
Circular economy (CE) describes a sustainable alternative approach to the current linear economy system. It is a growing topic among scholars, practitioners, and decisionmakers; it encompasses several concepts related to sustainability and requires the synergy of multiple actors for success, including higher education institutions (HEIs) as one of the most relevant ones. Current CE is based mostly on experiences in Global North developed countries, where the concept has gained great attention and has already influenced policies and strategies. However, CE in Latin American countries (LA countries) have not yet received such attention. Thus, some “unique problems” may remain unattended, and efforts to attain a CE are more likely to fail. Likewise, the study shows how the role of HEIs in CE in LA countries has not yet been fully explored, as the literature on this topic is scarce. This paper aims to address the main research question: what is the role of HEIs in the transition to a CE in Latin American countries? For this, a two-fold methodology was performed: (i) a systematic review which allows understanding of the trends of CE research in LA and the extent of the HEIs involvement; and (ii) a narrative review, which provides insights into the state of the art of CE research (gaps, drivers, and barriers) in LA countries and how this relates to HEIs. This approach drew implications for the role of HEIs in the implementation of CE in LA countries. HEIs are key actors in this transition, contributing in several ways to the CE by collaborating with industry, assisting policy makers, building human and intellectual capital, supporting community engagement projects, influencing campus culture, linking with international CE networks, and promoting an inclusive CE discourse. This research contributes to the CE body of knowledge from a Latin-American Global South perspective by discussing the factors that aim to define the role of HEIs in the CE transition in LA countries.

[PMID: 33486197 DOI: 10.1016/j.jenvman.2021.111992] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/15/2020] [Revised: 01/11/2021] [Accepted: 01/11/2021] [Indexed: 06/12/2023]
Abstract
Advancing toilet technologies to address public health and sanitation issues are a concern of governments and organizations. This article mainly studies the assessment methods for the public toilets and some rural toilets considering from design to demolition to assist for the innovation of toilet technologies. The Analytic Hierarchy Process (AHP) and Life Cycle Assessment (LCA) methods were adopted to identify the assessment indicators and rank the weight. The outcome of Toilet Assessment Scheme (TAS), which includes a set of weightings and a classification system for the selected assessment indicators and sub-indicators. The weight calculation result showed that water resources, ecology, and indoor environmental quality are relatively high, which indicates that saving water, protecting the environment and optimizing the toilet environment should be given priority at the current stage. The individual questionnaire experts from the perspective of gender, profession, and generation, have different emphases on the evaluation scheme. This study can improve the comprehensiveness of toilet evaluation under the distinct background conditions, and will play a relevant role in the promotion of new toilet technology. The TAS can accelerate the toilet revolution in areas where toilets are scarce, and thus will improve the sanitary and health conditions of these populations.
