What many people throw away without a second thought has been transformed into decent housing, security, and hope for vulnerable families in São Paulo. In a pilot project that stands out for its social and environmental impact, 20 houses built with walls made from recycled toothpaste tubes were delivered to residents of Favela dos Sonhos, in Ferraz de Vasconcelos.
The initiative, publicized by Recicla Sampa, showed that an apparently common waste product can gain a new life in civil construction. What once would have ended up in the trash has now become walls, panels, and structure for sustainable housing.
The project was named “The Power of a Smile” and was carried out in partnership with Gerando Falcões, a multinational company, and other partners. The proposal is simple but powerful: to use recycled materials to address two urgent problems simultaneously — waste disposal and the lack of adequate housing.

Families left shacks made of canvas, plastic, and cardboard
Before the new houses, many families lived in extremely precarious conditions. They were improvised shelters made of tarpaulins, plastic bags, fragile wood, and cardboard, without the minimum structure needed to withstand cold, rain, and intense heat.
The delivery of the homes took place in Favela dos Sonhos, a community located in Ferraz de Vasconcelos, in Greater São Paulo. The community’s name perfectly matches the proposal: to transform a reality marked by insecurity into a scenario of dignity, protection, and future.
The houses are not just symbolic. They were designed to offer real living conditions, with a bathroom, bedrooms, electrical and hydraulic installations, as well as materials with thermal and acoustic insulation. For those who lived exposed to the elements, this change represents a true turning point in life.
Ready-to-live homes assembled in record time
One of the most impressive aspects of the project is the speed of construction. The units are modular and can be assembled in up to 48 hours, according to information released about the initiative. This means that, in just a few days, a family can move from an improvised shelter into a structured home.
The residences were delivered with complete electrical and hydraulic systems, allowing immediate occupancy by vulnerable people. In practice, it’s not just about erecting walls, but about delivering a space with basic conditions for living with greater security.
Another striking detail is the size of the houses. Sources on the project cite units of approximately 27 m², with a wooden structure and panels made from recycled tubes. It’s a compact solution, but with enormous potential to serve communities that need quick responses.
Seven tons of toothpaste tubes found a new purpose
The environmental impact is also enormous. To make the homes viable, approximately 7 tons of toothpaste tubes were repurposed, transformed into panels used in the construction of the houses.
This type of packaging is often difficult to recycle because it combines plastic and aluminum. Precisely for this reason, finding a way to reuse this material on a large scale is a solution that can have an impact far beyond a single community.
Instead of remaining in the environment for hundreds of years, the waste is transformed into resistant, insulating, and waterproof panels. The technology shows how the circular economy can move from discourse to directly impacting the lives of those who need it most.
From “Boca do Sapo” to Favela of Dreams
The transformation also has a symbolic weight. The community was once known as the former Boca do Sapo, a name linked to the conditions of the territory before the interventions. With the advancement of the project, residents have begun to experience a new phase, marked by urban and social improvements.
The initiative is part of the Favela 3D — Digna, Digital e Desenvolvida program by Gerando Falcões. The idea is to combat poverty systematically, combining housing, infrastructure, technology, income generation, and community development.
In this context, the houses made from recycled toothpaste tubes are not just a sustainable curiosity. They are part of a larger strategy to prove that vulnerable communities can receive modern, fast, and environmentally responsible solutions.
An idea that can change the future of affordable housing
The case is impressive because it shows that the problem of waste can be connected to the solution of housing. The recycled toothpaste tubes transformed into construction material reveal a possible path to reduce waste while creating housing alternatives.
Of course, the project is still a pilot and does not solve the Brazilian housing deficit on its own. But it raises a powerful alert: materials discarded every day can become houses, schools, shelters, and useful structures.
In a country where millions of people still live without adequate housing, initiatives like this show that innovation does not need to be distant from reality. Sometimes, it starts with something as common as an empty toothpaste tube.
The inevitable question remains: if 20 sustainable houses have already been made possible, how many more could be built with the waste that Brazil discards every day?
