What to Compost

food scraps 350x266All eligible households in the Monday collection route will get a kitchen bin and compostable bags, and a green curbside green bin (to share at multi-family buildings up to 12 units). Place food scraps in your green kitchen bin lined with a compostable bag, or a paper bag. Place bags of food scraps into the green curbside bin every 2-3 days or if you're going away. No loose food in curbside bins.

Important Tips:

  • Keep liquids out (no milk, grease, or cooking oil) 
  • Try to drain excess moisture from food first 
  • Wrap meat, fish or shellfish in newspaper or paper bag
  • Keep the curbside bin locked and outside in a ventilated and if possible, shady spot 
  • Place the curbside bin out for weekly pickup, even if it is not full 
  • Clean your kitchen bucket in the dishwasher 
  • If needed, clean the curbside bin with soap and water. Drain liquids onto a grassy area. Wash water should never enter a catch basin because it goes straight to the Charles river.
  • Remember no plastic, no metal, no Styrofoam and no glass.
