Gardening Tools Put in Garbage Separate Metal Parts If you can separate metal tool heads from any plastic, wood or fiberglass handles, dispose of the metal pieces with scrap metal. Mixed materials cannot be recycled and go in the garbage. Ways to Reduce Borrow Tools From a Friend or Neighbor If you only need to use a garden tool once in a while, consider borrowing from a friend or neighbor instead of purchasing a brand new one. Ways to Reuse Sell or Donate Unwanted Tools If your tools are still in usable condition, consider selling them or donating them instead of throwing them away.
