At Field Environmental Instruments (FEI), every day is Earth Day.

Whether recycling printed paper for use as note paper, or re-using boxes and packing materials for shipments and interoffice transfers, there’s a company-wide desire to be responsible stewards of the environment.

At FEI’s Chicago and Portland branch locations, employees take home glass and plastic bottles for recycling. All FEI locations use recycled boxes and packaging materials for shipments. FEI Minneapolis also reuses corrugated boxes and bubble wrap (the office has never bought a single roll!) for shipping and participates in a weekly recycling program for paper and boxes that are not reusable.

FEI Seattle re-uses packing material from a nearby gun range in addition to using recycled ink cartridges. Instead of Styrofoam or plastic cups, FEI Seattle employees use reusable water bottles. In FEI Atlanta, employees recycle calibration gas and solution bottles, and also reuse its boxes. There are also plans to start a battery recycling program at all FEI locations. FEI is committed to being active locally while thinking globally.

FEI's commitment to the environment happens quietly behind the scenes. We are devoting this page to telling some of those stories. Thank you for reading!


Recycling is regarded as good for the environment. But repurposing, or reusing, recyclable items can be a more efficient and cost-saving use of resources.

The M. Mallinger Company, a sister company of Field Environmental Instruments, Inc., repurposes cardboard boxes, paper goods, pallets, packing supplies, and other items than can be used more than once. Instead of being recycled – or worse, being hauled away as trash – boxes and other goods are used again.
