Here we show that natural keratin, e.g. from poultry feathers, can be a very promising substitute for both. Feathers are not only tough, but also contain a relevant amount of sulphur in the form of disulphide bridges. These can be activated under vulcanisation conditions and then covalently bind to EPDM rubber to form a cross-linked network. The presence of spring waste increases the tensile and compressive strength as well as the hardness and reduces the rebound resilience. Due to their high nitrogen content of approximately 17%, the springs also improve the thermal stability of the composite, shifting the main degradation step from 400\u00b0C to 470\u00b0C and significantly slowing down decomposition. As elastomers are a large market and springs in particular are a voluminous waste, the combination of the two offers enormous ecological and economic prospects.<\/p>\n<p>M. Brenner, O.
