Recycling at its best and getting your heat for free. With a paper log briquette maker and a shredder you can turn your junk mail into a paper briquette that you can burn in your fireplace. FInally some benefit to getting all of that junk. It's not perfect in today's world where most of the paper is fire proof but it works.
It can also be fun. This photograph is a close up of the side of a freshly made paper briquette, still wet keeping the paper bright white. After it dries it turns more yellow and grey. I enjoyed capturing several versions where letters, colors, and shapes caught my eye.
