ManufacturingBox tackles two major challenges in informal settlements: plastic waste and inadequate housing. Their solution is a self-sustaining microfactory that converts plastic waste into durable, low-cost building bricks using solar energy. These bricks can be used to construct homes and sanitation facilities, improving living conditions while also creating jobs and fostering local waste management systems. Inspired by humanitarian engineering initiatives, the project promotes sustainability by turning waste into valuable resources, contributing to multiple UN Sustainable Development Goals, including poverty reduction, gender equality, and sustainable communities. Their innovative approach empowers communities to build a better future—brick by brick.
