  • Ask Umbra on food disposal

    Send your question to Umbra! Q. Dear Umbra, I’ve been trying to convince a friend to compost her food waste, now that she has a back yard. She claims that she plans to do so, but in the meantime, she’s sending all her food through the garbage disposal and says that it’s just as good, […]

  • For some eco-pioneers, solving the sludge problem means getting their hands dirty

    Part 3 of Grist’s special series on poop. Laura Allen, a 33-year-old teacher from Oakland, California, has a famous toilet.

  • Umbra on composting weeds

    Dear Umbra, I’ve been weeding the garden and yard, and got to thinking about some of the more invasive plants. I’ve heard that not everything goes in the compost pile, but what weeds can I toss in? I’m fairly new to the composting game, so any advice is much appreciated. Danielle Walker Monroe, Ore. Dearest […]

  • Umbra on composting feminine products

    Dear Umbra, OK, the kitty-litter thing pushed me over the edge. I know you are sick of writing about gross, yucky things, but I had to ask: if kitty litter is compostable, what about biodegradable maxipads and tampons? One of the leading natural feminine-care brands touts their stuff as being biodegradable and compostable. Can this […]
