Silica from vegetables: Phytolits

Silica increases a tyre’s wet grip and cuts its rolling resistance by around 30%. That translates into a 5-7% reduction in fuel consumption.

Conclusions

• Socio-economic transitions push to re-think our rawmaterial pool

• Agro-industry wastes can play a significant role in thisscenario

but

• We have to use Green Chemistry tools
