Eco-energy without limits? Research may find ways to make it happen

The Earth has its limits, as the climate crisis demonstrates. With the increasing extinction of species and the littering of the oceans (and even space) as a result of human activity, governments and institutions the world over are championing the concept of a circular economy. By closing material cycles, the environmental impacts associated with the extraction of raw materials are avoided and the waste problem solved. This approach is, however, not sufficient to build a sustainable society in and of itself, as it leaves the questions open of how much and how quickly materials can be cycled and what energy is used to power these cycles. After all, in a truly sustainable society, not only material flows but also energy flows must remain within the limits set by our home planet.
