If you have children in diapers, switching to cloth reusable diapers can be HUGE. When we did this, we were already recycling our plastics, aluminum, cardboard, and glass, and we were composting, so literally half of what was left was diapers. You can then switch to reusable baby wipes (no more plastic wipe packaging -- hooray!). Not to mention the money we save from not buying diapers or wipes anymore.
Our trash accumulates at a rate of maybe one bag per week now for a family of six, which was unimaginable to me five years ago. Since our recycling center also accepts electronics and batteries, our trash mostly consists now of non-recyclable plastic packaging -- bags, shrink wrap, styrofoam. Reducing or eliminating that stuff seems to be the stubborn final frontier.
I've heard mixed things about electronics recycling. Does anyone know if it's worth it, environmentally?
