Four tons of plastic that could have continued circulating as waste gained a function difficult to imagine when they were still inside packages: they became part of the walls of a house.
The home was delivered to Ana Rita in the municipality of Sonsón, in the department of Antioquia, Colombia.
With one bedroom, a kitchen, and a bathroom, the property was built with plastic wood profiles produced from recycled waste.

The delivery was announced by the Sonsón City Hall on November 6, 2025.
According to the municipal administration, Ana Rita had lived for years in housing conditions considered difficult and moved into a house described by the municipality as safe and sustainable.
The project reused about four tons of plastic and received an investment of over 20 million Colombian pesos from the city hall.
The amount was allocated to the purchase of materials and the payment of labor necessary for the construction.
The initiative was carried out in partnership with the Fundación Botellas de Amor, a Colombian organization that collects flexible plastics and transforms them into profiles used in housing, playgrounds, urban furniture, classrooms, and other social projects.
Plastic wood house was not made with stacked bottles
Although the project is linked to the so-called “bottles of love,” the construction does not consist of simply stacking containers filled with plastic to form walls.
The bottles serve as a way to gather and compact flexible plastic waste that often appears in everyday life, mainly in packaging, bags, and wrappers.
Once collected, this material undergoes processing and is converted into rigid pieces known as plastic wood.
The result has a shape similar to boards, slats, or profiles used in assembly systems.
These pieces can be cut and organized to compose different parts of a construction, according to the adopted project.
In Ana Rita’s house, the Sonsón City Hall reported that the home was built 100% with plastic wood from the recycling of the four tons of waste.
The official disclosure, however, did not detail the composition of elements such as foundation, roof, plumbing, and finishes.
This difference helps to understand what lies behind the expression “plastic house.”
The property does not have walls made of loose packaging, but of components manufactured after the waste is separated, gathered, and transformed into construction material.
Discarded packaging becomes construction material
The Botellas de Amor Foundation focuses part of its work on flexible plastics.
This group includes lightweight materials used in various types of packaging, which can present difficulties in collection, separation, and utilization in traditional recycling systems.
The strategy promoted by the entity guides residents, schools, and companies to place these clean and dry residues inside plastic bottles.
The content is compacted to take up less space and sent to collection points.
After recovery, the plastics are processed and transformed into recycled profiles.
According to the foundation, the resulting material is used in social projects aimed at families, educational institutions, and communities.
In the case of Sonsón, the amount reused reached four tons.
This weight corresponds to the raw material reported for the manufacture of the plastic wood used in the new residence.
The city hall did not disclose how many packages or bottles were needed to gather this volume.
As containers and residues have different sizes and weights, it is not possible to convert the four tons into an exact number of units without additional data.
Recycled housing has bedroom, kitchen, and bathroom
The house delivered to Ana Rita has a compact configuration, consisting of a bedroom, a kitchen, and a bathroom.
The municipal disclosure did not provide the total area of the property, the dimensions of each room, or the time needed to complete the construction.
Details about the land, the method used to fix the panels, or the participation of professionals responsible for the structural project were also not presented.
Therefore, it is not possible to technically compare this construction with a conventional house based solely on the published data.
What is confirmed is that the system allowed the transformation of recycled plastic into components of a livable dwelling, with basic spaces for daily life.
Photos and videos released during construction show plastic wood pieces being used in the assembly of the walls.
Records prior to delivery already indicated that the house would be intended for Ana Rita and would use the four tons of recycled material.
In addition to the Botellas de Amor Foundation and the municipal administration, Mayor Juan Diego Zuluaga cited the support of the Homecenter network.
According to a report later published by the foundation, companies in the region also committed to donating necessary appliances for the residence.
City Hall invested more than 20 million pesos
The public contribution of over 20 million Colombian pesos covered materials and labor, according to information released by the Sonsón administration.
The city hall did not present a spreadsheet with the breakdown of expenses.
Thus, it is not informed how much was allocated to recycled profiles, transportation, assembly, or other stages of construction.
There is also no confirmation that the disclosed amount represents the full cost of the house.
Since the project involved public and private partners, other materials or services may have been provided through donations.
The use of plastic wood, therefore, does not allow us to state, with the available data, that the residence cost less than a conventional construction of similar size.
The comparison would depend on information such as area, type of foundation, finishes, transportation expenses, duration of the work, and locally practiced values for other construction systems.
Even so, the case shows a concrete application of the circular economy.
Instead of ending the cycle as waste, the plastic returned to the production chain in another form and became part of a permanent use structure.
Project brought together city hall, foundation, and companies
The construction was presented as a result of the collaboration between the Sonsón City Hall, the Botellas de Amor Foundation, companies, and community members.
During the delivery, Mayor Juan Diego Zuluaga linked the project to the combination of sustainability and social assistance.
“This delivery symbolizes how sustainability and solidarity can walk together. Each recycled bottle contributed to restoring dignity to a family in Sonsón,” declared the mayor, in a free translation.
The statement aligns with the central proposal of the foundation, which seeks to associate waste collection with the production of structures intended for community projects.
Created in Colombia, the organization reports that the recycled plastic profiles are used in the construction of social interest housing, playgrounds, school and urban furniture, classrooms, and collective spaces.
The house in Sonsón was not the first application of this system.
The people responsible for the Fundación Botellas de Amor report that the very origin of the project is linked to the construction of a residence with five tons of recycled plastic, an experience that helped demonstrate the use of the material in housing structures.
How recycled plastic wood works
Despite the name, plastic wood is not taken from trees.
The term is used because the profiles can take on shapes and some functions similar to those of wooden pieces used in construction and furniture manufacturing.
In the Colombian project, the raw material comes from recovered plastic waste.
After processing, the material no longer resembles the packaging from which it originated and becomes standardized pieces.
The foundation presents this system as an alternative to reduce waste disposal and produce resistant components intended for social projects.
