A Founding Principle Upheld by Every Employee-Owner
A founding principle of SIGMA Group is our commitment to sustainability. That commitment starts with our CEO and is carried out by every one of our 100+ employee-owners across all seven divisions of our company.
We understand how important it is, to our customers and the world, to reduce environmental harm and uphold ethical standards, all while delivering the quality products and professional services you expect from us.
Reducing Waste Through Smarter Procurement
At SIGMA, we take pride in our sustainable procurement practices, which include:
- Reselling refurbished, used, and idle equipment and MRO parts
- Reconditioning and repairing equipment in-house whenever possible
- Recycling responsibly and securely when reuse isn’t an option
By keeping equipment and parts in circulation, we help reduce unnecessary waste and support a more sustainable manufacturing lifecycle.


A Warehouse That Works Smarter
Our centrally located Midwest warehouse helps reduce the carbon footprint of deliveries by getting your packages to you faster and more efficiently.
Inside the building, sustainability is built into every detail:
- Motion-activated LED lighting conserves energy across our large facility
- Temperature-controlled environments keep employees safe and comfortable while improving energy efficiency
- One of the country’s largest inventories of surplus parts means smarter sourcing and fewer shipments
Social Responsibility Starts With Our People
Sustainability also means giving back.
As an employee-owned company, our team actively participates in initiatives that extend our impact across the community:
- Hosting semi-annual electronics recycling events
- Participating in blood drives
- Donating over 100 holiday gifts each year to support children and the elderly
We also hold ourselves to high ethical and labor standards because doing the right thing starts from within.

Social Responsibility Starts With Our People
Our guiding principles are simple:
Put the customer first. Do the right thing — by you and by our planet.
