that the toothbrushes you can buy at trader joe's are recyclable? t.j.'s carries recycline toothbrushes, and I've been using them for several years. recycline provides postage-paid envelopes, which are available right at the store. just save up a few used ones, pop them in the envelope, and send them back to recycline. the recycled polypropylene toothbrushes are used to make plastic lumber.
also good to know- t.j.'s stocks tom's of maine toothpaste, which comes in a recyclable aluminum tube. (unlike most, which are made of non-recyclable materials)
