With depletion of natural resources and growing awareness of the limited capabilities of the globe to cope with pollution, the need to design life-time recycling loops for all types of products is steadily increasing. Rubber articles of all sorts and the need for a proper disposal of these at the end of their life-cycle cannot escape this trend, and also come more and more into focus. Most conspicuous in this context are tires, of which appr. 800,000,000 are scrapped world-wide on a yearly basis. If piled up at a height of 25 cm each, it establishes a pile of 200,000 km, 2/3 of the distance to the moon: per year! Apart from the environmental problems which these scrap tires represent, they actually are also a source of valuable materials if they can be recycled and reused in proper ways.
The present paper reviews latest developments in the recycling: de-vulcanization of rubber articles, including tires of various sorts, and the contribution which the research in the university of Twente has played in this field. It highlights what has been achieved for different major rubber types, but also what the hurdles are to be taken before rubber recycling is as obvious a technology as the manufacturing of first use rubber-articles.
