The Crain family has been growing and processing quality English
walnuts in the Sacramento Valley since 1960. Over the past forty
years, the business has grown to be one of the largest walnut
producing operations in the world. With this growth came the need
to develop a by-products division. In 1995, ECO-SHELL, Inc. evolved allowing the opportunity to provide a full
spectrum of walnut shell products.
Since ECO-SHELL was
formed, it has grown and continues to upgrade its facility with
the finest state of the art milling and processing equipment.
ECO-SHELL is one of the premier suppliers of
walnut shell media to industrial markets around the world. As a
result of having a substantial in-house raw material supply
ECO-SHELL is capable of entering long-term contracts and can
guarantee a consistent supply without interruption.
provides controlled environment storage for all of our raw shell.
This is an important aspect of our quality assurance. In
addition, our processing and milling operation warehouses are
maintained to the highest sanitation standards. We can provide
complete documentation on all process controls and Quality Control
analysis data of every lot or shipment.
