en.Wedoany.com Reported - A biodigester provided by Israeli company HomeBiogas has been put into operation at a school in Tubarão, Santa Catarina, Brazil, converting food waste into kitchen gas with a monthly output equivalent to approximately three 13-kilogram gas canisters.

The device is installed on campus and processes organic waste through anaerobic digestion. Bacteria consume food scraps and produce gas, which is stored in the system and directly connected to the stove. The entire process requires no electricity, and the equipment operates independently of external energy sources.

Food scraps such as onion peels, potato skins, and apple peels generated daily by the school kitchen serve as raw materials for the system. The monthly output is nearly three 13-kilogram gas canisters, precisely meeting the school's daily needs for preparing meals for children. The residual fertilizer from the process is used to nourish the community garden on campus.

The system forms a complete, observable closed loop: lunch leftovers return to the device to produce gas, fertilizer nourishes the garden, and vegetables re-enter the lunch menu. Reports indicate that while saving gas is listed as the project's primary goal, the city government emphasizes that the educational aspect is the most important part of the project. The teaching plan utilizes every link, allowing students to experience the processes of soil preparation, sowing, vegetable growth, and harvesting.

The biodigester was delivered by the Israeli company HomeBiogas as part of a collaboration between the Israeli Consulate and the Tubarão city government. The partnership also includes other projects, such as introducing irrigation technology to urban gardens.

The application of the device brings dual benefits to the school: reducing gas expenses while decreasing the amount of food waste that needs to be transported to landfills, thereby lowering public costs for waste collection and treatment.
