The biodigesters are working!

In early July, EARTH University Agricultural Engineer Luis Carazo was able to visit the two farms in Guanacaste that we traveled to in March to install biodigesters. These biodigesters were installed to help these two families manage the animal waste generated through their cattle, pig, and goat operations.

At Gustavo Acevedo's farm, Luis found that improvements to the pig pen waste water collection had been made. Now, all water is chaneled and flows to the separator. This avoids an accumulation of dirty effluent around the pig pens and thus prevents the generation of bad odors and flies around the family dwelling.

In addition, the hose that transfers the biogas generated by the biodigester to the family's kitchen stove was connected and modifications were made to the stove to put burners in a position where they can be utilized for cooking. Furthermore, this stove will be used to pasteurize the milk that they will use to produce yogurt on the farm to maximize the use of the biogas produced on a daily basis.

At the second farm, a flexible metal fence was installed to keep the farm animals from getting into the biodigester ditch. Approximately one month prior to the visit, a goat on the farm pierced a part of the biodigester bag, which was hindering full use of the gas stove. Luis quickly repaired the hole in the biodigester during his visit and taught the family how to handle similar maintenance issues in the future.

Luis reports that both families are excited to see their biodigesters producing methane gas that can now be used for cooking and pasteurization of sellable farm goods.

Finally, all of us at EARTH University would like to thank all of our supporters. This project has been fully funded, and we look forward to being able to install dozens more biodigesters on local farms in Costa Rica. Thank you!!
