Univers-sel relies on Cycleco’s expertise to assess the benefits of a new salt farming technique on West Africa’s population’s living conditions
True to its adaptation and innovation (and therefore population-oriented) historic values in the field of environmental protection, Cycleco’s engineering team looked into the impact of an emblematic activity of a small West African country: salt farming. A more complex task than it appears at first sight, which addresses environmental, human and societal issues…
Univers-sel and its local partner Kafo, put forth a salt farming technique directly inspired by Atlantic coast salt marshes, also called solar method, which simply consists in pouring the brine on a black polymer sheet, and letting the sun and the wind proceed until salt crystals are obtained via evaporation. This technique can replace the current method which relies on wood fire.
Cycleco conducted a life cycle impact assessment of both techniques and the solar technique has 100 times less consequences on greenhouse gas emissions! Indeed, as Cycleco explains it in details in its report, methane emissions occuring during the incomplete combustion of wood generate 325g of CO2 per kilo of salt produced. When it comes to human health, the benefits are immediate and even more dramatic. The study clearly shows that using polymer sheets can reduce the impact on health by a factor of 10,000 to 100,000, and in practical terms, increase by 9 years the life of a woman who practices salt farming during 30 years!
