Abstract
The waste of foodstuffs is increasing in the agri-food industries. This is reflected in the increasing volume of their waste. Food is thrown away on criteria that have nosthing to do with its nutritional quality. In most cases, the criteria are shape, color and stains. In order to reduce this waste, a way of valorization was investigated. This paper focuses on waste reduction through feeding the Abidjan zoo animals with the unsold products of three agro-industries. The unsold products collected by the zoo were characterized over an 8-year period (2011 to 2019). Deaths and births were recorded. The food needs met by the unsold products harvested were evaluated and the economic gains estimated. The results showed that the food recovered by the Abidjan Zoo at SOCOCE contained 34.94% fruit, 38.58% vegetable and 23.47% meat products. At SCB and Coquivoire the donations are estimated at 2 tons of bananas and 1.5 tons of chickens (smoked and cold chicken) respectively. These donations allowed the Zoo to save 25.94% of its budget allocated to animal feed. The diversity of the food collected has a positive impact on the quality of life of the animals at the Zoo. This is reflected in an increase in the number of births from 0 to 12 per year and a decrease in mortality of 90%.
Highlights
Global waste generation has doubled over the past decade and is expected to reach 69% by 2025, if trends continue [1]

Summary
Global waste generation has doubled over the past decade and is expected to reach 69% by 2025, if trends continue [1]. Among this waste, there appears unsold food from marketing structures and agri-foods industries which constitute food loss and waste. [2] has shown that approximately 38,000 large supermarkets in the United States generate 1,100,000,000 pounds of produce that are currently sent to landfills His analysis suggests that repurposing surplus produce from supermarket discards can have significant beneficial outcomes for new food markets and the environment. Feeding unsold food to animals is an alternative to systematic landfilling This form of valorization has led to reflection on their food value and, their potential economic interest
