Sustainable design is a valuable part of our ethos at Optima as we strive to create vibrant communities built with the surrounding natural environment at the forefront. Now more than ever before, changemakers across the world are expanding the possibilities for what sustainable designs resemble. Today, we’re spotlighting a leader in sustainable design and affordable construction: Gjenge Makers and its founder, Nzambi Matee.
In 2017, Nzambi Matee, then an engineer working for Kenya’s oil industry, threw everything she knew away to create a startup aimed to address the need for affordable and sustainable construction materials in her home country of Kenya and across the world. Her first thought immediately went to plastic, a material creating pollution problems across Eastern African countries like Kenya, where Matee has resided her whole life.
Thanks to her academic background, including a major in material science, along with experience working as an engineer, Matee understood which plastics would easily bind together and built the needed machinery, allowing her to mass produce the building alternative. Today, Gjenge collects waste materials from local factories and other recyclers and then uses a mixture of plastic and sand to form durable bricks and tiles.
The designs aren’t just sustainable and durable. Matee and the Gjenge team wanted the finished products to emulate a sense of beauty, and today, bricks come in an array of colors, including red, blue, brown and green. Since its founding, Gjenge has transformed more than 22 tons of plastic into various alternative building materials and created more than 100 jobs for local garbage collectors, women and youth.
We can’t wait to continue exploring the ways innovative architecture can contribute to a healthier, more sustainable world, especially with changemakers like Matee impacting the lives of others daily.
