IR is my current employer, and here is my take at a logo redesign for the company.
The logo mark is an "IR" monogram, with R being the shell and i fitting inside the negative space.
The tittle of the "i" is comprised of the negative space of a refresh symbol (2 spinning arrows), further alluding to the reuse & recycle theme of the brand.
For the colors, I went with a minty-green and a dark blue. Customers typically correspond Blue with "trust" and "authority", and green is light and friendly while keeping true to the "green" values of the brand.
