Quantification and traceability of mango by-products in the Hauts-Bassins and Cascades regions of Burkina Faso

Résumé

This study provides a regional analysis of mango by-product generation and
traceability in the Hauts-Bassins and Cascades regions of Burkina Faso.
Through field surveys conducted in samples of 89 processing units and
stakeholder mapping, the study quantifies the volume and flow of mango
residues and identifies key stakeholders and bottlenecks in the post-harvest
chain. Although traceability practices remain largely manual, the study
identifies opportunities for digital integration and the added value of
utilizing by-products in agro-industrial applications. A total of 52,691 tons
of fresh mangoes were processed, primarily from seven varieties. Five types
of by-products were identified, with peels, kernels, and sorting waste being
the most prevalent. These by-products represented 49.66% of the total
processed mango mass. Most by-products were discarded indiscriminately,
with only minimal portions allocated to livestock feed (1%) and agriculture
(2%). Physical analyses conducted in drying units and laboratories revealed
that processing methods significantly increased by-product generation,
resulting in pulp losses of up to 31.8%. These results provide a foundation
for optimizing the utilization of mango by-products in Burkina Faso through
technological innovations. The findings support strategic planning for
sustainable resource management and lay the groundwork for the future
deployment of traceability systems in tropical agricultural contexts.
