This video series showcases two sustainable models in the coffee value chain in Son La, developed by the Northwest Agriculture and Forestry Research & Development Center (NOMAFSI) with support from ALiSEA. The models include a microbial wastewater treatment system that reduces pollution, saves costs, and enables water reuse for agriculture, and a coffee husk composting model that turns by-products into organic fertilizer to improve soil health and reduce input expenses. Together, they promote a greener, cleaner, and more sustainable coffee sector in Son La.
