Working freight at my store, I touch dozens of silica packets each day and have often wondered what I can do to recycle them. Couldn't we collect them and send them off to a manufacturer for reuse? What Is Silica Gel? Silica gel is a desiccant, a substance that absorbs moisture. Despite its misleading name, the silicate is actually a very porous mineral with a natural attraction to water molecules. Manufacturers utilize the gel to keep goods from spoiling, molding or degrading due to humidity. Most silica found in our food and household purchases looks like tapioca beads and is benign unless combined with certain chemicals. The gel itself is nontoxic, but sometimes a moisture indicator called cobalt chloride is added; it's a known toxin that turns pink when hydrated and is otherwise blue in its dry form. These days, you can find new indicators (usually green) that don't use this toxic ingredient. However, to be safe, use the packets with no added chemicals around the food-related suggestions below and save the indicator-added packets for other uses. Although silica gel has massive potential for reuse, I haven't had any luck finding a recycler. But I did discover several great suggestions for using these packs around the house and keeping them from the landfill just a wee bit longer.
