In rural Senegal in West Africa, an enterprising woman named Aissatou Ly is earning an extra few bucks a day selling a tasty, nutritious ground-peanut paste dubbed "peanut butter" at a local market.
That is thanks to a simple grinder that has cut her labor and increased her income markedly in a country where the per capita economic output is only about $2,500 annually.
"The grinder is simple and durable and I don't need help to fix it, or need gas" to run it, said Ly in a written statement from Senegal. "I provide grinding services to other women and I sell peanut butter. I use the money to support my family. I like that, in my community, I've been able to find an opportunity … to become self-sufficient."
This is the recently improved version of the grinder, first developed years ago for small farmers and entrepreneurs in several African and Latin American countries by the retired science and business volunteers at Compatible Technology International (CTI) of St. Paul.
CTI opened a Senegal office two years ago and already several hundred of the $275 grinders have been distributed to small entrepreneurs who cover the acquisition cost within a few months with increased income, benefiting families and communities with better nutrition and improved incomes.
"The farmers and others can more quickly process peanuts or grains in less time and add value to products they sell in the market," said Aliou Ndiaye, CTI's Senegal country director on a recent visit to 35-year-old CTI's St. Paul headquarters and shop. "We are marketing the product, which has been improved. We are training them on the tools, business model and financing. We're changing the way they work, so they can feed their families better and sell more product to get more income.
"Most of them repay over several months with the increased income."
The improved grinder, which can be hand-operated or run with an electric motor, is the latest innovation for CTI. It was designed in consultation with the African people who use them and can be repaired locally.
