More and more teachers want to teach their students how they can conserve resources in their everyday lives and work. In the "LehrRess" project, the IZT and its research partner Faktor10 have therefore made special materials freely available for download that deal with this broad topic based on the life worlds of the learners - such as "The ecological rucksack of a mobile phone", "Coffee-to-go" and "Planned obsolescence". The "LehrRess" project is listed in the German Resource Efficiency Programme (ProgRess). It served both the further training of teachers and the implementation of lessons. The client was the VDI Resource Efficiency Centre.

LehrRess aimed to develop teaching materials to promote (further) education in the area of resource conservation and resource efficiency. A BilRess study showed that while material and energy efficiency were strongly addressed in some training occupations, they were only addressed to a limited extent across the board. However, the question of resources, with special attention to the use of raw materials, is a central question for the future. Every use of raw materials is associated with enormous material and energy expenditures.

For example, it is estimated that the production of a smartphone alone requires between 50 and 100 kg of raw materials - even if the device weighs only 0.1 kg. In order to draw attention to this problem, teaching and learning materials were developed. All materials were designed for different fields of action and design, which at the same time serve to further educate the pedagogues. The BilRess network was operated within the framework of the Competence Centre for Resource Efficiency 2015 to 2019, which is based at the VDI Zentrum Ressourceneffizienz GmbH (VDI ZRE).
