Sustainable technology brings sanitation and energy to indigenous village in Brazil

Sao Paulo, Nov 21 (EFE).- Without access to water, sewage and electricity networks, the Tekua Itakupe indigenous village took an important step to improve the quality of life of its inhabitants with the installation of a sustainable technology that now offers them a sanitary and energetic solution.

Through a joint action carried out by the multinational Softys and the NGO Techo, five autonomous sanitary systems were installed last Saturday that, from waste, generate biogas and organic fertilizers for this village where 40 families of the Guarani ethnic group live. .

Tekua Itakupe is one of six villages that are part of the Jaraguá reserve, the smallest indigenous land in Brazil, located on the outskirts of the Sao Paulo metropolitan area, a concrete jungle where 22 million people live.


The solution developed by the Israeli company HomeBiogas together with the UN, designed for peoples living in the desert, is already present in 110 countries.

It consists of a reactor that receives the waste from a bathroom and also the remains of food and animal excrement, an organic material that is decomposed by bacteria and later converted into biogas and fertilizer.

The biogas is used as energy to supply a kitchen and the fertilizer is used to fertilize the crops in the community.

From the installation, each reactor takes about fifteen days to start generating biogas, and can produce up to 40 liters of liquid fertilizer per day and about 13 kilos of gas per month.

“These bathrooms give us some peace of mind, because we don’t have basic sanitation, so they bring more hygiene and we can also teach children how ecological work works and how it will bring more balance to nature,” Wera, one of of the community leaders of Tekoa Itakupe.

The 26-year-old highlighted the importance of the action that mitigates one of the most urgent problems in the village, sanitation, and pointed out that gas generation also provides “financial peace of mind” for the more than 100 residents of the village, Most of which have crafts as their main source of income.


The indigenous leader defended the use of new technologies by native peoples, something seen as a taboo by Brazilian society.

In his opinion, these initiatives show that it is possible to “reach a balance between the Guarani and non-indigenous culture.”

“Society believes that, as indigenous people, we cannot evolve technologically (…) But we see that we can associate technology with sustainability while respecting nature, which is one of the principles of the Guarani culture,” he explained.


The initiative carried out in Tekoa Itakupe is a pilot project that will be taken to other communities in Latin America and that is part of the Softys Contigo project, which seeks to contribute concretely to the UN Sustainable Development Goals, specifically that of Water Clean and Sanitation.

To do this, the company will invest 6 million dollars to facilitate access to drinking water and sanitation for people living in communities and popular settlements in Latin America.

In this sense, the general director of Softys in Brazil, Luis Delfim, recalls that 35 million people do not have access to water and more than 100 million are not connected to a sanitation network in the South American giant.

“When there is such a large volume of people with such basic needs, we as a company, and all other companies, have to contribute,” he defended.

The Softys Contigo project foresees the installation of 2,000 solutions throughout Latin America by 2026, 300 of them in Brazil.

Just in 2022, a total of 181 solutions will be installed in the region, benefiting more than 1,200 people and mobilizing more than 540 volunteers among company employees.

“We are part of a group that is 102 years old, and if we want to be around for another 100, 200 years, we have to put social responsibility into practice. For this reason, ESG criteria, whether from a social, governance or environmental point of view, are increasingly part of the decision-making process”, concluded Delfin.
