On behalf of all of us at EARTH University Foundation, thank you to all of our current donors! At the end of March one of our staff members traveled to the Guanacaste region of Costa Rica with a group of five volunteers from California to install two biodigesters and kitchens on local farms. EARTH University staff led the technical side of the trip, which proved to be quite impactful to the farmers who received the new biodigesters.

The first biodigester installation was done on Gustavo Acevedo’s family farm, which focuses on the production of milk and a small collection of pigs available for sale at the local market. The family’s main source of income is derived from selling dairy products. With the installation of the biodigester, which will treat farm waste and provide energy at a lower cost, they hope to begin producing yogurt, which is more costly and time-intensive to produce due to the pasteurization process required. Throughout the day, Gustavo and his sons, who live with their families on the farm, assisted the EARTH team and expressed much gratitude at the end of the day as everyone cooled off in the late afternoon shade.

The biodigester gas-production cycle takes approximately 30 days. By the end of April, EARTH staff will travel to Gustavo’s farm again to witness some of the inaugural cooking and pasteurization that will be done in their new kitchen. Thanks to your donations, Gustavo’s family will now pay less for fuel and will earn more income by being able to introduce yogurt as a new commercial product at the local market.

Thank you again, and please stay tuned for updates on our second biodigester installation!
