Worldwide we are in desperate need of (affordable) houses for a population of 2 billion people by 2030. A the same time, we are facing an unprecedented amount of plastic waste growing by hundreds of megatons a year. Unibricks brings these two problems together: a construction block made of plastic waste. Unibrick will be competitive with local building materials and provide a flexible way of constructing qualitative, reliable buildings. Whether it is through homes, schools, or community buildings, the Unibrick empowers local people to build on a self-supporting community.
