Evolution of silica to the sustainable Nzerosil series from renewable rice husk
Nzerosil sustainable silicas made from biorenewable rice husk agricultural waste and manufactured for green tire treads are examined. One current goal of the tire industry is to replace all oil derived materials with sustainable products derived from renewable biomass sources. Silica can be directly obtained from eco-friendly sustainable materials of bio-origin, including rice husk (hull) and rice straw (dried leaf), cornflower, sorghum (grass flowers) and bagasse (sugar cane)
