Making a worm compost bin

by Sam Goodfellow
& Emma O’Donnell


  • Large plastic storage container with a lid
  • Drill
  • Piece of fine screen
  • Newspaper
  • Spray bottle of water
  • Food scraps
  • Indoor breed of worm e.g. red wiggler worms



  • Drill 10 small holes on the sides and bottom of the storage container. These allow the worms to breath and release excess liquid.
  • Cover the holes with a piece of screen so the worms don’t escape.
  • Fill ½ to ¾ of the container with strips of newspaper. This will serve as a bed and food for the worms.
  • Spray the newspaper with water so the worms don’t dry out.
  • Add your worms to the container.
  • Bury scrap foods within the newspaper. Worms eat a variety of food, fruit and vegetable peels are a good example and contain lots of nutrients.
  • Place the bin in a warm area but out of direct sunlight.
  • Regularly feed the worms and check the moisture levels of the composting bin. It needs to be moist without being overly wet.
