Composting food scraps is optional at multifamily communities. Check with the property manager first to see if your building is participating.

If your multifamily community is participating in the Portland Composts! program, food scraps can be placed in the green container provided by the garbage and recycling company. Composting food scraps reduces waste and creates energy and nutrient-rich fertilizer.
