Pencil Shavings in Compost: Graphite OK, Cedar Toxic

Kelli asks about pencil shavings. Graphite = potassium source (approved in organic). But pencils: graphite/clay fired, dipped in wax/oil, glued in cedar, varnished. Cedar contains phenols—toxic to small animals (liver/kidney damage, respiratory irritation). Shavings in compost → eaten by wildlife → harm. Don't compost. Recycle instead.
