Waste to Wealth XPRIZE
Our planet is drowning in its own trash. Poor waste management, particularly throughout the world's cities, is a growing global grand challenge that impacts the health of humans, the local and global environment, and the economy as a whole. Global metropolitan waste volumes are projected to grow from 1.3 billion tons of solid waste per year to 2.2 billion tons by 2025, while yearly costs are expected to increase from $205.4 billion to roughly $375 billion. Developing countries will be most impacted by these rising costs, which are projected to grow more than 5-fold. What if we found a safe, cost-effective way to transform the world’s trash into reusable energy?
