Now you can put the “natural” in artificial turf infill with Safeshell!

Meet the no-hassle, low-maintenance, 100% organic infill of your dreams.


Low Maintenance

Unlike other organic infills, Safeshell stays in place, doesn't breakdown and doesn't change in the hot or wet climates. The round shape of each grain helps the product resist compaction. It doesn’t float and plays the same wet or dry. You get all the benefits of an organic infill without all the added maintenance.

Naturally Durable

As the most durable natural infill on the market, Safeshell is made from one of the hardest nut shells on the planet. It won’t break down and it doesn't float, which means there is limited migration of the product and it stays in place. With the 8 year warranty and limited top-off required, you'll be able to always depend on Safeshell for athletic fields, yards, playgrounds, and more.

Cooler Temperatures

Safeshell excels at evaporative cooling - the key to a cooler playing surface. It absorbs water with minimal expansion and then releases it slowly over time to help keep surfaces from heating up too quickly. No water? That’s okay, even dry, Safeshell plays cooler than crumb rubber.


With Safeshell, you get peace of mind that your infill is made from organic and food-grade components. Now, you can let athletes focus on the competition and small children and pets play with abandon!


Without processing, Safeshell wouldn’t! We teamed up with a leading biotechnology firm to develop a patent-pending process that eliminates allergens that remain on the shell after separation from the nut. Following FDA guidelines, our process removes allergens below 2.4 parts per million.

Grown in the USA

Safeshell is made of 100% USA grown walnut shells. When buying Safeshell, you're supporting American farmers and agriculture. From their fields to yours!

A proprietary blend

To achieve optimal performance, we blend Black and English walnut shells to make Safeshell. Why? Black walnut shells are thicker; once the shells are ground, the grains are rounder and less abrasive. Using all-round grains would be shifty, so we combine them with the thinner, less round grains of ground English shells. The result is a proprietary mix that’s the perfect balance of firm, fast and player-friendly.

USDA BioPreferred

Safeshell contains 100% USDA certified biobased content showing our company meets the high standards set forth by the USDA Secretary of Agriculture. For more information, go to
