Kenyans Plastic Bricks Out Of Plastic Waste
Building Aa Sustainable Future With Kenyans Turn Plastic Waste Into Plastic Bricks
In the vibrant city of Nairobi, Kenya, an innovative solution to make recycled plastic bricks is taking shape. Nzambi Matee, a materials scientist and the founder of Gjenge Makers, has developed a groundbreaking method to transform plastic waste into durable, affordable building bricks. This initiative not only addresses the pressing issue of plastic pollution but also provides a sustainable alternative to traditional construction materials.
The Plastic Challenge
Kenya, like many other countries, faces a significant challenge with plastic waste. Despite efforts to reduce the use of single-use plastics, the nation continues to generate large amounts of plastic waste daily. This waste often ends up in landfills, rivers, and oceans, causing environmental harm and posing health risks to communities.
An Ingenious Solution
Nzambi Matee saw potential in what others considered waste. Her company, Gjenge Makers, collects non-recyclable plastic waste and combines it with sand to create durable bricks. These bricks are not only cost-effective but also much stronger than conventional concrete bricks. The process involves sorting the plastic, heating it until it melts, and then mixing it with sand before molding it into bricks. The result is a product that is up to seven times stronger than concrete and significantly cheaper.
How These Bricks Work
The innovative bricks created by Gjenge Makers are designed to be both practical and sustainable.
Material Collection
The process begins with the collection of non-recyclable plastic waste, which includes various types of plastic that cannot be processed by conventional recycling facilities.
Processing
The collected plastic is cleaned, sorted, and shredded into smaller pieces to facilitate the melting process.
Mixing
The shredded plastic is heated until it melts. This molten plastic is then mixed with sand in specific proportions to achieve the desired strength and durability.
Molding
The plastic-sand mixture is poured into molds to form bricks of standard sizes, ensuring they can be used in conventional construction projects.
Cooling and Curing
Once molded, the bricks are cooled and allowed to cure, ensuring they harden and achieve their maximum strength.
Strength and Longevity of Plastic Bricks
The bricks produced by Gjenge Makers are renowned for their remarkable strength and longevity.
Superior Strength
These bricks are up to seven times stronger than traditional concrete bricks, making them suitable for load-bearing structures and various construction applications.
Weather Resistance
The bricks are highly resistant to extreme weather conditions, including temperatures, moisture, and UV radiation, ensuring they do not degrade over time.
Chemical Resistance
The plastic material used in the bricks is resistant to many chemicals, preventing deterioration caused by exposure to pollutants and other harmful substances.
Low Maintenance
Due to their durability and resistance to environmental factors, these bricks require minimal maintenance, reducing long-term costs associated with building upkeep.
Sustainable Lifespan
By repurposing plastic waste, these bricks contribute to a circular economy. Their long lifespan means they will not need to be replaced frequently, further reducing the environmental impact of construction.
