Meet Eco-Shell

We were founded in 1995 to provide biodegradable, non-toxic, environmentally safe, and cost-effective walnut shell products to an array of industries.

Growing Walnuts Since 1960

The Crain family has been growing and processing quality English walnuts in the Sacramento Valley since 1960. The business has transformed into one of the largest walnut-producing operations in the world, necessitating the development of a byproducts division. In 1995, Eco-Shell, Inc. was founded — and with it the opportunity to provide a full spectrum of walnut shell products.

Since Eco-Shell was formed, we’ve continued to upgrade our facility with the finest state-of-the-art milling and processing equipment. As one of the premier suppliers of in-house raw material walnut shell to industrial markets around the world, Eco-Shell can enter long-term contracts and guarantee a consistent supply without interruption.
