Evaluation des déchets générés par la chaîne de valorisation de l’ananas au Bénin Assessment of Waste Generated Along the Pineapple Value Chain in Benin

Abstract

The pineapple value chain in Benin represents a major source of income and employment for agricultural and commercial actors. This study aims to characterize the waste generated throughout the value chain and to identify the key determinants of its production. The sample included 161 producers, 52 processors, and 70 traders in the Atlantique Department. The results reveal marked heterogeneity in waste generation. Among producers, leaves (97.5%) and non-marketable fruits (80%) constitute the main residues, while suckers remain marginal (36%). Processing units primarily generate peels, crowns, pomace, and washing effluents, with volumes varying according to processing methods and organizational structures. Among traders, whole fruits represent the main source of losses, followed by peels and crowns. Statistical analysis indicates that producers’ age influences sucker generation, while yields and cultivated area affect non-marketable fruits and suckers, respectively. For traders, business profile and available stock significantly determine waste production, particularly peels (r = −0.72). Among processors, the generation of peels, pomace, and crowns depends on turnover and years of operation. These findings highlight the need for differentiated waste management and valorization strategies tailored to the practices and profiles of value chain actors, in order to reduce losses, promote circular economy principles, and optimize resource use within the pineapple sector in Benin.
