Foyer amélioré, modèle préservateur de niveau 3 ,4 et 5 pour une cuisson propre : outil de capture de gaz à effet de serre, des particules PM10, PM2,5 pour un développement durable.

Abstract

This study addresses the challenges of climate change and domestic pollution in Madagascar by developing improved cooking stoves (levels 3, 4 and 5 according to ISO 19867-1:2018), combining optimized combustion with filtration systems for fine particles (PM10, PM2.5) and greenhouse gases (CO₂). Results show that these prototypes deliver significant reductions in pollutant emissions (up to 75% for PM10), improved energy efficiency (thermal efficiency increased by 30-50%) and substantial fuel savings (30-60%). Analysis reveals that these solutions are accessible and culturally appropriate for Malagasy households, while contributing to the Sustainable Development Goals (SDGs 3, 7 and 13). Experimental results confirm their potential to improve indoor air quality, reduce pressure on forest resources and offer a sustainable energy alternative. This technological innovation thus represents a concrete response to the health, environmental and energy issues associated with domestic cooking in Madagascar.
