Goodyear are one of the world's largest tyre manufacturers. In order to maintain their leading position, they continuously carry out scientific research to improve the performance of their tyres; at the same time, they are sensitive to environmental issues, and they seek to reduce the polluting components used in the production processes to a minimum.
The Basic Problem:
Carbon black, which has been used in tyre production for over a century, and silica, which has been on the market for only ten years, are not eco-compatible. Furthermore, oil is a natural source that is in increasingly short supply, and for this reason, the cost of petrol continues to rise.
Therefore, we need to find a new technology that enables us to use less of the oil reserves, that is environmentally sustainable, and that achieves a high level of product quality.
Novamont's collaboration with Goodyear led to the creation of the bio-tyre, which uses BioTred technology, an environmentally sustainable solution that achieves new levels of performance.
Using maize starch, Novamont created a biofiller that replaces the carbon black and silica in tyres.
Thanks to the natural internal structure of its mix, the bio-tyre achieves:
- A reduction in fuel consumption, thanks to the lower resistance to rolling (even with respect to the current 'energy' mixes)
- Better road-holding in the wet, and therefore better safety;
- A reduction in the weight of the tyre;
- Lower consumption of the tread;
- A reduction in noise, and therefore, in sound pollution
- A reduction in carbon dioxide emissions (of the order of 10 g per kilometre), and therefore, in atmospheric pollution;
- A reduction in the amount of energy used to produce the tyres.
Savings due to the use of less fuel. It has been calculated that for a distance of 15,000 km covered per year, the fuel saving for the driver is over €150 (a value linked to the average price of oil in the year 2000). Furthermore, the bio-tyre costs no more than traditional tyres.
Better performance and greater road safety.
Lower environmental impact.
