Nowadays, the environmental requirements are more and more important in all industrial fields and notably in the automotive sector. That requires to work the most to develop new products, which are 100 % recyclable. Today, the automotive products comprise several raw materials which are difficult to separate, and partially recyclable. An analysis of 204 synthetic filter medium types on the market was carried out. The principal objective of the studies presented in developing textile structures (nonwovens) composed of thermoplastic (recycled or not) mono material having the same characteristics (acoustic, comfort, mechanical behaviour, filtration efficiency, dust holding capacity, pressure drop, etc.), even better than existing products of the automotive market. This new concept will allow to reduce the production of last wastes in the automotive sector and even to define a new method of valorization in closed circuit of an automotive product. The aims of those studies are to replace classical engine air filter and classical acoustic insulation products manufactured in several raw materials, which are difficult to separate, and partially recyclable by filter or textiles structures (nonwovens) composed of a thermoplastic (recyclable or not) mono material. The recycling of this mono material was studied for automotive applications or for other fields. The key advantages which manufacturers grant unquestionably to the synthetic media are increased capacity and their recyclability. However, they will also be studying the new requirements such as fire behaviour, resistance to humidity, behaviour with soot types etc. As for recycling, the major advantage of those synthetic media and acoustic structures, the crushing and shredding tests carried out on industrial units allow us to conclude that they are industrial recyclable with such technologies.
