This fantastic. I'm naturally cheap so proving an ROI is always a seller for me. We have been making our own laundry detergent for several years now. Recipes abound on the net, but a box of borax, arm and hammer washing powder and a bar of zote with 5-10 minutes of work can provide a lot of cheap and relatively green detergent. I recently appraised a 600,000 SF industrial warehouse in the mid-atlantic which stored nothing but laundry detergent. Felt good knowing I don't generate demand for that space, shipping or product.
Our 3rd child had cloth diapers, the new bum genius stuff is a million miles from the old ones and it saved us roughly $130/month compared to the disposables.
Sadly most people are creatures of habit and simply go along with the herd. There are too many reasons for people to be looking into this stuff (composting, hugelkultur, rmh) but the just keep moving through life with blinders on.
Thank you for permies, fantastic stuff.
