Questions & Answers

Have a Question?

Ask a Question
  • Where can one get the "bulking agent" recommended? Or, is there another material that can be used?

    It's a very good question and an important one to make your hot compost a success.  The quick answer is that you can collect dry leaves, the fallen branches and sticks from trees and bushes in your backyard.  You can also cut up some old cardboard, especially if you mail order a lot, you will have abundant supply of cardboards boxes.  The key is to create volume so that air can fill the space and allow the organism to grow and do its magic.

    This is a very good article about bulking agent.  Take a look.  Feel free to contact us if you need more clarification.

  • Can I put leaves and grass clippings in my HOTBIN?

    Leaves can be stored and are great to mix in with "easy to digest" waste such as grass. If you have a large lawn and trees  you can try mixing grass and leaves 50/50 by volume, then add that mixture into your HOTBIN. This mix will get to 140 F and reduce in volume rapidly, enabling you to top up in 5-7 days.

  • Can I put coffee grounds in the HOTBIN?

    We get quite a few questions asking if you can compost tea bags and coffee grounds in the HOTBIN. The answer is a resounding yes!
