Composting. I started a new compost pile using shredded cardboard, shredded paper, egg shells and coffee grounds. Made the pile adding coffee grounds between layers. Never heated up during a few weeks. So, I moved the pile, wet down each layer and added more coffee grounds. That was like 3 or 4 days ago. Yesterday it was 120 degrees, today it was 140 degrees. It should start decomposing now!
