Perlite for Sustainability & The Environment

Tools for Environmental Clean-up

Perlite is increasingly used to filter solids from contaminated water and absorb hazardous liquid waste due to its high-surface area, light weight, low-reactivity, and availability in a variety of grades and sizes. It is used in the transportation sector to filter stormwater runoff from roads and highways. It is found in eco-roofs where it is used to reduce the effects of stormwater surges. And fine perlite is used to absorb sludge prior to transport to landfills.
