New technologies can be the basis for resource-efficient products and services and thus create eco-innovations, either by creating new functionalities in existing or new application fields or by substituting existing technologies in existing or new application fields. In this paper, an overview over different technology fields, products and strategies with resource efficiency potential, such as nanotechnologies, material science, manufacturing technologies, process technologies and cross-cutting issues, is presented. There is a special focus on applications from nanotechnology issuing, e.g. functional surfaces or new 'smart' materials with special functionalities. Furthermore, it is shown how companies can use the method Resource Efficiency Technology Radar to identify and evaluate technologies with resource efficiency in order to incorporate them into their development activities.
