We based one part of the review system on recycling. If the company we talked to recycled, we added 1 star.

We also asked the companies if they use reusable products, and if they did we gave them another star.

If the company uses biodegradable products, we added another star.

We also asked the companies where they get their products, and added a star if they buy locally.

If the company was energy conscious, for example uses LED lightbulbs, we added a star.
