Eco-friendly homes starting from R$ 60 thousand are entering the sustainable construction market, utilizing recycled plastic from the petrochemical chain and promising savings in climate control; in Belém, the company Amazônia Domos offers models with automation and digital locks.

The company Amazônia Domos, from Belém (PA), sells ecological geodesic dome-shaped houses starting from R$ 60 thousand. The structures are made with recycled plastic, pressed açaí residues, and sustainably managed wood, and leave the factory with pre-installed electrical, hydraulic, digital lock, and voice command systems. Founded by architect Tuane Costa and administrator Thales Barca, the company saw increased demand following COP 30, the UN climate conference held in Belém in November 2025.

The market for ecological houses in Brazil has gained a competitor that blends Amazonian bioeconomy with home automation technology. Amazônia Domos, from Belém (PA), sells dwellings in the shape of a geodesic dome starting from R$ 60 thousand, with walls made of recycled plastic with a distinct texture, pressed açaí residues, and sustainably managed wood. The structures leave the factory with pre-installed electrical and hydraulic systems, a digital lock, and voice command, a combination that positions the product between sustainable construction and smart homes.

According to G1, the company was founded by architect Tuane Costa and administrator Thales Barca. Amazônia Domos is also listed as a winner of the Sebrae-PA Inova Amazônia award and participated in the Villa Domos project, a partnership with the Origem Justa organization to host COP 30 visitors in Belém, as reported by the Belém Negócios website. Six months after the event that placed the capital of Pará at the center of the global climate debate, Amazônia Domos represents one of the concrete cases of the conference’s economic legacy: a local company that transforms regional materials into ecological houses with environmental appeal and scalability potential.

What is a geodesic dome and why is it efficient

The geodesic dome is a dome-shaped structure formed by a mesh of triangles that distributes weight evenly, eliminating the need for internal columns. The concept was popularized by American architect Buckminster Fuller in the 1950s and has since found applications in dwellings, greenhouses, sports arenas, and, more recently, in eco-tourism accommodations (glamping). The triangular geometry provides structural resistance disproportionate to the weight of the materials used.

Energy efficiency is one of the strongest arguments for this format. The spherical shape allows for natural air circulation inside, which can reduce air conditioning use by up to 30%, according to manufacturers in the sector. In a region like the Amazon, where climate control is a permanent cost in any property, this saving makes the dome competitive not only for its environmental appeal but also for the electricity bill. Thermal and acoustic insulation complements the efficiency and differentiates the product from conventional constructions.

The regional differential of Amazônia Domos lies in its materials. The walls use recycled plastic from the petrochemical chain with a texture the company describes as “lunar,” in addition to pressed açaí residues that utilize the seed of Pará’s most consumed fruit. The wood used in the structure is from sustainable forest management, and the internal tiles are made with regional patterns by local artisans.

The use of recycled plastic connects sustainable construction to the circular **economy** of the fossil chain: the **material** that came out of **petrochemicals** as disposable packaging gains a second life as a construction component. For the Brazilian petrochemical industry, which invests in recycling programs like Picplast, cases like Amazônia Domos are concrete examples that **plastic** can have a destination beyond the landfill. The question that remains is whether these **materials** already have constructive use certification according to ABNT standards, information that the company has not publicly detailed.

Automation that comes from the factory

The **ecological** **houses** of **Amazônia** **Domos** are not just **sustainable**: they come with pre-installed smart home **technology**. Digital lock, voice command, and electrical and hydraulic parts already come assembled from the factory, which reduces **installation** time on the site and eliminates the need to hire electricians and plumbers for basic infrastructure. One of the walls is made of glass, allowing a view of the sky, a detail that enhances the **product** for **tourist** accommodation use.

Modularity is another strong point. The dome arrives at the site as a kit that can be assembled in a few days, unlike conventional **construction** that takes months. For glamping entrepreneurs, **ecological** inns, and event spaces, the speed of **installation** means faster financial return. For residents, it means less construction time and less inconvenience. The modular format also facilitates logistics in the Amazon, where road access to many localities is precarious.

The dome market in Brazil and competitors

**Amazônia** **Domos** is not the only **company** selling **ecological** **houses** in the form of **geodesic** **domes** in **Brazil**. Companies like Ameríndia, which advertises itself as a supplier of structural kits, Domolar, with models ranging from R$ 38.6 thousand to R$ 152.8 thousand, and Goodome have been operating in the national market for years, primarily serving the tourism and glamping segment. The **market** is still forming, without consolidated size or growth data, but COP 30 seems to have accelerated interest.

**Price** comparison raises questions. The R$ 60,000 value of Amazônia Domos is higher than that of competitors who sell basic 16 m² domes for less than R$ 40,000, which suggests that the **price** includes differentials such as **automation**, regional **materials**, and interior finishing. However, without public detailing of what is included (assembly, foundation, freight, furniture), the consumer has no way to adequately compare. For those considering a purchase, the recommendation is to request a detailed quote and visit an assembled **dome** before closing a deal.

The legacy of COP 30 and the Amazonian bioeconomy

**Belém** hosted the planet’s largest climate conference in November 2025, and six months later, the first signs of economic legacy are beginning to appear. Amazônia Domos is one of the cases riding the wave of attention that COP 30 brought to the Amazonian bioeconomy, a concept that values the **sustainable** use of the region’s natural resources as a basis for economic activities. The **açaí** that becomes a wall, the **managed** **wood** that becomes a **structure**, and the **plastic** that gains a second life illustrate this proposal.

The question is whether this movement survives when the spotlight fades. Events like the COP generate peaks of interest that do not always convert into sustained demand, and **Amazônia** **Domos** has not disclosed sales figures that would allow evaluating whether the growth is real or just the partners’ impression. For the Brazilian **sustainable** **construction** **market**, which still represents a small fraction of the sector, every **company** that survives and scales contributes to normalizing practices that today seem niche.

Would you live in an ecological house made of recycled plastic and açaí waste, or do you think a geodesic dome only works for glamping and tourism? Tell us in the comments if you already knew about this type of construction and how much you would pay for sustainable housing with automation.
