Project in indigenous community of Chiapas transforms plastic without conventional recycling into blocks used in the construction of social housing with solar panels, efficient stoves, and international sustainability certification, uniting environmental technology, popular housing, and community participation in a region marked by historical challenges of access to adequate housing.
Habitat for Humanity Mexico delivered 11 sustainable houses to Tzotzil families of the Monte Sion community, in San Cristóbal de las Casas, in the state of Chiapas, Mexico.
The homes benefit 42 people, including 19 adults and 23 children, and use concrete blocks with RESIN8, a technology that incorporates non-recyclable plastic into civil construction.
The units are part of the Lekil’Na project, a name chosen by the community itself and associated with the idea of “sustainable housing” in Tzotzil.

The initiative combines social housing, waste reuse, energy efficiency, and solutions adapted to the cultural reality of the indigenous families served.
Sustainable houses in Chiapas use non-recyclable plastic in construction
The houses were not built entirely with plastic.
The material appears in the concrete blocks, which receive RESIN8, an aggregate produced from plastic waste that would not be utilized by conventional recycling processes.
The proposal seeks to give a new destination to waste that is difficult to reuse and, at the same time, reduce the dependence on virgin materials in some of the components used in walls and floors.
Thus, the discarded plastic becomes part of a permanent housing structure.
In addition to the blocks with RESIN8, the houses were designed with solar panels, efficient wood stoves, and solutions aimed at reducing domestic costs.
The project also includes EDGE certification, a system linked to the International Finance Corporation, part of the World Bank Group.
The certification considers criteria of efficiency, sustainability, and well-being in constructions.
In the case of Monte Sion, this point differentiates the initiative from isolated actions of waste reuse, as it links social housing to international standards of environmental performance.
Participation of the indigenous community was incorporated into the project
The families participated in the construction of the units alongside Habitat for Humanity Mexico.
The model aimed to deliver affordable, safe homes suitable to local needs, with legal security of ownership and respect for community organization.
In Chiapas, the choice of community gives the project a broader social dimension.
Monte Sion is located in a mountainous region of San Cristóbal de las Casas and brings together indigenous families facing historical challenges in accessing adequate housing.
The initiative also incorporated local customs into the design of the houses.
Information released by Habitat indicates that the organization worked with residents and community leaders to adapt the internal and external spaces to the daily practices of the families.
Among the planned resources are kitchen areas designed to reduce smoke exposure, as well as more efficient energy and food preparation solutions.
In communities where firewood still plays a significant role in domestic routines, more efficient stoves can reduce consumption and improve comfort.
RESIN8 technology transforms plastic waste into material for concrete
RESIN8 is presented as a technology capable of transforming plastic without conventional recycling into material for concrete.
In practice, the waste is converted into aggregates used in the composition of blocks and floors, without completely replacing concrete.
This type of application draws attention because it addresses one of the most challenging parts of the waste crisis.
Many discarded plastics do not have sufficient commercial value, do not enter traditional recycling chains, or end up in landfills and irregular disposal.
By entering civil construction, this material gains a new function within permanent structures.
The change does not eliminate the impacts of concrete but expands the use of reused materials in housing intended for low-income families.
Partnership between companies and the social sector enabled housing
The execution involved Habitat for Humanity Mexico, Wesco, CRDC Mexico, and Dow.
Wesco had already announced financial support of more than $111,000 for the development of the Lekil’Na project, within a partnership aimed at sustainable construction in Monte Sion.
In a previous statement, Christine Wolf, Executive Vice President and Chief Human Resources Officer of Wesco International, stated that the company was committed to generating environmental and social impact in the communities where it operates.
The statement was made in the context of the partnership with Habitat and the families of Monte Sion.
The delivery of the 11 houses shows a concrete application of environmental technology outside of demonstration environments.
Instead of being restricted to prototypes, the solution reached families who began living in homes designed to offer safety, efficiency, and cultural adaptation.
Sustainable social housing gains space in real projects
The participation of the Tzotzil community also prevents the project from being presented solely as a technical innovation.
The design of the houses, the name of the initiative, and the participatory construction reinforce the attempt to integrate technology, local culture, and housing needs.
The experience in Chiapas broadens the debate on the role of sustainability in social housing.
Projects like this indicate that affordable housing can incorporate recycled materials, energy efficiency, and environmental certifications without neglecting the primary function of housing.
Even so, initiatives of this type depend on technical validation, proper maintenance, and performance monitoring over time.
Therefore, EDGE certification and the use of specific materials are important elements to differentiate the proposal from makeshift solutions.
The delivery in Monte Sion repositions non-recyclable plastic within the production chain.
A waste usually associated with disposal, environmental cost, and pollution becomes part of houses intended for indigenous families, connecting engineering, social inclusion, and more responsible use of materials.
