The Jora JK400 Composter simplifies and speeds up the process of making compost. It is a 'continuous-use' dual chamber composter. Dual chambers allow you to keep adding new materials to one compartment while the other matures. Because the unit is insulated and sealed, it converts kitchen waste to compost in as little as two weeks.

With a capacity of 14.2 cubic feet, the Jora JK400 can easily handle large quantities of kitchen scraps and garden waste. Suitable for larger households, restaurants, schools, or shared use between multiple families.

Features & Benefits:

  • 'Continuous-use' dual chamber composter
  • Durable, rust-resistant galvanized steel construction
  • Holds 14.2 cubic feet (106 gallons) of compost
  • Operating capacity: 13 to 21 gallons per week
  • Easy to use - tumbles easily for maximum aeration
  • Insulated - great for cool climates and all-weather composting
  • Fully-enclosed and pest resistant
  • Rodent proof design
  • Reduces odors

Dual Compartments

The JK400 is divided into two large compartments, so one side can be filled while the other side's compost matures. Once the compartment being filled can take no more, the mature compost can be emptied from the other compartment, and the cycle begins again. You can use the composter continuously, with no waiting between batches.


The composting process generates heat, and different microorganisms work at different temperatures. The HDPE insulation in the JK400 composter allows the temperature to rise higher than 160F resulting in faster and more efficient processing of your organic waste. At these temperatures the process is so rapid that fresh waste starts to break down before it has a chance to rot and attract pests. With its superior insulation, the JK400 Composter will continue working through winter, long after other composters have stopped completely.

Rotating Compost

  • Easy to rotate - simply turn by hand after adding waste
  • Fresh waste is brought into direct contact with decaying waste
  • Adds air to the mixture, providing oxygen vital for microbial activity

What can be composted?

  • Raw and cooked food scraps (e.g. vegetables, fruit, eggshells, meat, fish, bread)
  • Garden waste (e.g. flower cuttings, leaves, weeds, grass clippings)
  • Shredded paper and cardboard (e.g. egg cartons)
  • Light pet waste (e.g. rabbit or hamster bedding)

The JK400 Composter will accept organic household waste or anything biodegradable. After adding waste, it will take about 6 to 8 weeks for each chamber to produce compost. Once both chambers are in operation you should be emptying one chamber every 3 to 4 weeks.


  • Exterior: galvanized, powder-coated steel panels
  • Insulation: 2.16" HDPE polyethylene - a stable, non-toxic plastic
  • Stand: galvanized steel
  • Stainless steel hardware

    • Can this be used in our basement? Or is it better outside?
    • Yes, you can locate your Jora composter in the basement. Being in a heated environment will help speed the composting process. However you'll need to keep your compost in balance, usually by adding carbon-based materials, to ensure there are no odors from the composter.
