Steaming Piles of Compost

httpv://www.youtube.com/watch?v=1908VmFlQ8Y Good short clip showing the steam... probably the coolest part of composting through the cold months. How to do it?  Have a pile at least 3'x3'x3' in size, comprised of half shredded browns (preferably leaves).  Add the food scraps, cover with more browns, moisten, cover the pile with a tarp or lots of straw.

When the Left-Hand doesn’t know what the Right-Hand (PLA) is doing.

originally found here: http://woodsend.org/2013/09/left-hand-doesnt-right-hand-pla-doing/ American and European consumers are very familiar with PLA widely marketed as compostable for just about everything from chip-bags to golf-tees.  This renowned PLA, a biological plastic made from a “left-hand” lactic-acid molecule, also has a quirk:  it requires a pre-heat phase before it will actually biodegrade. That trait is referred to as Tg or “glassy transition” in the trade.  Tg is a feature of all plastics and can occur over a very wide range of temperatures, but none as convenient as PLA’s at 55-58°C, making it eligible to be called compostable,- that is, if the compostability test is conducted at or just above the Tg  temperature. To be certified compostable means a standard is upheld such as ASTM 6400 for USA or EN 13432 for…

Okay to put weeds in compost pile (video)

I would simplify the video by saying that if you're working with a large compost bin, you can definitely compost weeds with no problem.  However, in smaller volumes there's just not enough heat generated for a sustained period of time to kill the weed seeds. Personally I like to put a big stack of weeds on top of my compost as an insulating layer, because I simply…
