What should I put in the bin ?

Anything organic- that is anything that was once living, whether animal or vegetable can be composted but some materials are more appropriate than others for home composting. Organic material falls into two categories  : “Green” & “Brown” .“Green” or  “Nitrogen Rich” organic material is wet and often green like grass clippings or fruit and vegetables.“Brown” or “Carbon Rich” organic material is dry, woody material that is usually brown, such as fallen leaves, and tree-cuttings . The following list of materials can be composted at home. It has been separated into “Green”and “Brown” for simple identification.

  • Coffee grounds
  •   Tea leaves and tea bags
  • Fruit and vegetable waste (cooked or uncooked) - roots, cores, etc
  • Bread, pasta & rice
  • Cut and dead flowers

  • Grass cuttings and green leaves (Good Activator) #
  • Weeds (Avoid weed seeds)
