Analyzing the territorial dimensions of work through a comparative study of waste recovery facilities in France and Brazil

Abstract

BACKGROUND: Waste production and management from residents and collection for sorting are systems heavily dependent on territorial dimensions. Ergonomic research needs to better integrate such territorial determinants to improve work conditions and design sustainable work systems. OBJECTIVE: Through studies in France and Brazil, this paper analyzes the territorial relations that raise work systems’ sustainability challenges for materials recovery facilities (MRFs) and waste management in both countries and examines the links between work activity and territory in MRFs. METHODS: Both studies were based on the principles of activity-oriented ergonomics and used analyses of work activity and sociotechnical systems. The French study focused on interventions conducted over a 42-month period in five MRFs. The Brazilian study was based on a 20-month longitudinal qualitative and quantitative study. RESULTS: In this paper, we argue that territory is a key determining factor in waste production and work. Notably, the consumption patterns of residents and the economic flows within a geographic space determine the waste composition; and the territorially specified public policies, which define technical and social dimensions of waste collection and sorting. However, the territorial dimensions of waste are poorly considered in facility design. Workers’ health and sorting system performance are thus affected and negatively compromising plant performance. CONCLUSION: The territory appears as a blind spot in the design of work systems. One of the challenges is to create interfaces and devices that could help to integrate better human activity and waste territorialized anchorage, in a multilevel organization, from local communities to the global recycling chains.
