The pilot project of the municipality of Ilhabela, in São Paulo, which installed a biodigester in the Paulo Renato Costa Souza school, in the Barra Velha district, has already started to operate. The initiative is supported by the city’s Environment Secretariat.

According to Leandro Toledano, representative of HomeBiogas, the school is the first public school to use the system in Latin America.

Already in gas production, since the beginning of December, 10 kg of food and school waste can be dumped daily, which reduces the waste generated to be used as cooking gas.

The goal of the project is to install three or four additional biodigesters to transform all your waste into methane gas, which, among other advantages, will save you the purchase of gas bottles for cooking. In addition to generating biofertilizers, it is a solution to improve sanitation and reduce waste production. The action also integrates the activities of the “Blue Green” municipal program.

“Our city is a pioneer in Living Environment Education initiatives, in alliance with the Ministry of Education, which means that the composters, the biodigester and all the workshops offered to students and teachers are tools for us help in teaching, so that we can offer live courses in physics, chemistry and biology, ”said Environment Secretary Maria Salete Magalhães. “These are reference initiatives allowing the student to participate, to get involved in the process, to understand what gas and the biodigester are, and to experience what waste is, the importance of it. process properly and what it can become like fertilizer, gas and electricity, ”he continued.


It is a biodigester that transforms organic waste into biogas and liquid organic fertilizers. The system encourages the use of biogas for cooking in a specific kitchen shipped with the equipment, as well as the use of fertilizers for the natural treatment of gardens and green spaces.

Biodigestion, on a small scale, is an ancient process that, when done safely and effectively, is capable of changing people’s perceptions of the production and disposal of organic waste.

Each Homebiogas system encourages local treatment of up to one ton of organic waste per year and helps reduce the greenhouse effect, stopping the emission of six tons per year of harmful gases into the environment.
