Cindy Mora Abarca Builds a Home with Recycled Plastic Blocks in Costa Rica

For many families, the search for a home of their own demands unwavering commitment and continual sacrifice. One Costa Rican resident turned years of work into an admirable achievement, showing that green technology and solidarity can make innovative housing projects possible in vulnerable low-income areas.

How did persistence make buying the plot possible?

Cindy Mora Abarca spent almost a decade setting money aside with great discipline. In Alajuelita, Costa Rica, she eventually fulfilled her ambition of purchasing a plot, illustrating how personal effort is the first step towards securing much-needed housing.

Yet, even after obtaining the land, putting up the walls of her home appeared financially out of reach. With no extra funds available, conventional building work could not begin straight away, exposing the challenging reality faced by people seeking to build without any form of support.

Which partners made the building project a reality?

The combined efforts of social organisations and private companies made the building structure feasible. Support from Habitat for Humanity Costa Rica, Procter & Gamble, Urbarium and Ekojunto delivered an effective technical solution to address the lack of resources.

This strategic collaboration provided the resident with all the engineering support required. The initiative created decent, safe housing, demonstrating how collective cooperation can have a direct impact in communities facing severe social vulnerability.

Below is a video from Ekojunto Costa Rica's YouTube channel that explores the points discussed in this topic in greater depth:

How do recycled plastic interlocking blocks work?

The Bloqueplas system uses modular components made from recycled discarded materials. This industrial method enables solid walls to be assembled very quickly, shortening construction time while providing excellent thermal and acoustic insulation for the new home.

The modular technology avoids excessive use of water and cement when the walls are assembled. The plastic pieces offer strong resistance to fire and weather, turning polluting waste into a safe, highly durable alternative.

Construction advantages

Key benefits of the recycled-plastic model:

1. Quick, straightforward wall assembly;
2. High resistance to flames and moisture;
3. Effective natural acoustic and thermal insulation.

What is the ecological impact of reusing 7 tonnes of waste?

Using 7 tonnes of plastic prevented this substantial volume from polluting rivers, soil and oceans. Large-scale reuse supports the circular economy, transforming accumulated urban waste into valuable, useful material for housing infrastructure.

Closing the materials loop eases pressure on landfill sites and reduces the construction industry's carbon footprint. This model proves that municipal solid waste has valuable potential to advance sustainable development.

Using plastic waste in residential construction brings several direct environmental benefits:

• A significant reduction in plastic rubbish discarded into nature;
• A sharp decrease in the consumption of conventional masonry materials;
• Continued support for the recycling chain and environmental preservation.

What does this initiative mean for the future of housing?

Cindy's story shows that sustainable technology is a viable way to tackle the housing shortage. Integrated green projects provide families with dignity and offer an inspiring model of innovation for cities pursuing affordable urban solutions.

Expanding partnerships between the private sector and community organisations strengthens new construction alternatives around the world. This sustainable approach protects the environment while delivering security and comfort to those most in need of a home.
