What We Do

We believe sustainability and acting in an environmentally friendly way is our spirit

At STG's core, we buy gently used computers from certified suppliers such as Hewlett Packard, Lenovo or Dell to ensure the highest quality. After receiving the units, STG follows a detailed procedure to physically and digitally clean each computer, load it with the proper Microsoft technology and then finally run every one through stringent tests to ensure the computer is fully functional and up to standards. On a larger scale, STG makes the earth a greener place by refurbishing and essentially recycling over 10,000 computers every month that may have been otherwise disposed of as waste. Furthermore, STG takes computer components that cannot be used any longer and sends them to a program that properly recycles the parts. This allows STG to reduce its ecological footprint on the world as much as possible. Overall, STG like any business, strives to make a profit, but here is our difference; we plan on taking care of Mother Nature in the process of doing so.

What are Refurbished Computers?

Refurbished computers are older gently used computer components that have undergone a thorough evaluation and restoration process that make the computer fully functional. In general, a refurbished computer will sell at a price somewhat below that of a new similar make and model, and will carry a limited warranty. A number of major computer manufacturers offer refurbished computers for sale at discounted prices.
