We all know that CO2 concentrations in the air are reaching their limits and that climate change is occurring. We all know that waste and CO2 are dirty. We all know that we are spoiled with our current energy system and should worry about all our waste. But… what if we DID care? What if we STOPPED being spoiled? What if we didn’t define products as waste, but saw CO2 and other residuals as a valuable starting point? What if we designed solutions for clean CO2-free energy? What if we innovate our energy and material system towards something different? How can we give guidance to various stakeholders to make the right decisions and reach a cleaner more waste-free world? What guidance is needed?

Do you have any suggestions on how to do so? We challenge everyone to bring new ideas to the table! Your ideas do not have to provide a complete and overall answer to our broad research question. We are looking for concrete ideas, both small and large, rather than abstract thoughts. We are excited to discover more about your ideas, so go ahead and submit them!
