Arena Recycling Industry was established in 2018 with the aim of saving the world from plastic waste. The company is a social business enterprise that collects plastic waste from beaches in Dar es Salaam and produces building materials such as Eco-Bricks, paving blocks and tiles out of recycled plastic waste for the construction of affordable houses, toilets, and other buildings in rural areas. This solution not only contributes to plastic-free beaches and waterways but also helps bridge the water and sanitation gap by constructing water tanks and latrines with eco-bricks. Arena educate and promote the change of behavior in waste disposal, by involving community into recycling logistics and improve their income by buying collected plastic waste from the environment. The collected plastics are then sorted according to density, melted, and mixed with sand to produce bricks.
