Transforming Waste into Resources for a Climate-Resilient Future
The Global Waste-to-Energy Research and Technology Council – WtERT® is an international academic network with a mission to advance sustainable technologies for the recycling and recovery of materials and energy from residual, non-recyclable waste. This represents the future of Waste-to-X (waste-to-value), where waste becomes a resource: powering energy, fuels, chemicals, and new circular solutions
Founded by the Earth Engineering Center of Columbia University, WtERT® brings together leading universities and research institutions worldwide to advance sustainable waste management. Today, its global leadership is jointly led by Columbia University and the College of Energy Engineering at Zhejiang University.
WtERT® is a global science-based knowledge hub providing trusted expertise to governments, international organizations, and industry—advancing innovation at the intersection of academia, policy, and technology to accelerate climate action and build a circular, low-carbon economy through Waste-to-X solutions, grounded in its recognized leadership in Waste-to-Energy.
