Alison Aerogel insulation products are composed primarily of synthetic amorphous silica impregnated onto a substrate. The final product does not contain any liquid material. Scrap aerogel products can be disposed of in landfills that are approved to accept industrial waste. Scrap aerogel products will generate dust during landfill operations. Industrial waste landfills should be informed of the potential for dust generation during the waste approval process.
