What can I put into the machine?

The general rule: anything a human can consume (raw or cooked) can be composted in the machine.

What cannot be put into the machine?

Do not put anything into the machine that is not organic, including:

  • plastic
  • glass
  • metal
  • food containers and packaging

Also avoid

  • large bones
  • hard seafood shells (oyster, scollop and abalone).
  • cooking oil

Putting these items into the machine can potentially lead to machine damage and malfunction.

Can I put bones into the machine?

Small sized bones can be put into the machine.
(e.g. chicken bones, fish bones)

Large swine bones, lamb shank bones or cow bones are not recommend.

Can I put seafood shells into the machine?

Only soft seafood shells can be put into the machine such as shrimp, prawn, lobster and crab.

Do not put oysters, scollops or abalone shells.

Can I put yard trimmings into the machine?

No, the units are for food waste only.

How often can I put food waste into the machine?

Whenever is convenient for you!
The composting process will be complete 24 hours after the last food waste input.

Do I ever have to replenish the bacteria culture?

Closed Loop Organic’s Commercial Composters use naturally occurring microbes that will regenerate themselves continuously during the composting process.

Can I put compostable products into the machine?

YES, if it is certified compostable product – Australian Standard AS4736 – 2006.
Please note that these products will take longer than 48 hours to compost. Compostable product input should also be no more than 10% of daily capacity and should be shredded prior to being added to the unit.

How often does the machine need to be emptied?

On average, compost will need to be unloaded from the machine once a week.

Is the compost harmful to humans or animals?

As the compost unit pasteurises harmful pathogen are removed as per testing to Australian Standard AS4454 – 2012.

How do I handle the compost?

Just like composts, mulches and fertilisers that can be purchased from your local nursery or garden supplier, the composted material from your machine should be treated with the same care as these also contain micro-organisms.

  • When handling you should avoid breathing its mists or dust
  • Wear a particulate mask if it is dusty
  • Wear gloves and keep the product moist when handling
  • Wash your hands immediately after use

What if plastic materials are put into the machine by mistake?

Since there is no crushing or grinding taking place during the operation, no harm will be caused to the compost or the machine. However, the heat from the machine will cause plastic to deform and potentially release undesired substances into the compost, hence we recommend strict segregation of compostable and non-compostable items to avoid such instances.

Does the machine produce any harmful discharge or gas?

Closed Loop Organic’s Commercial Composters mimic the natural composting system, sped up through the use of our proprietary bacteria culture. It does not have grey water discharge, nor any harmful gasses.

How are Closed Loop Organic’s Commercial Composters different from food waste dehydrators?

Food waste dehydrators often require sewer hook up.
Ours commercial composters do not as the stream generated from the composting process is extracted and absorbed by our deoderisers.

The output from dehydrators have the same characteristics of dried up food waste, and is not recommended to be used as soil amendment.
Our commercial composters produce a nutrient rich material that can be used in gardens.

How are Closed Loop Organic’s Commercial Composters different from food waste digesters?

Food waste digesters require water supply and access to drain or water waste hook up. The output of digesters is grey water effluent that needs further processing at wastewater treatment plants, and often have high biological oxygen demand (BOD), and fats, oil and grease (FOG) content. Closed Loop Organic’s Commercial Composters do not require water hook up, and produces a nutrient-rich material that can be used in gardens.

Most digesters use microorganisms or wood chips that require replensihing, while our micororganisms self-regenerate, and do not need to be replaced.

What can I use the compost for?

Compost can be used in any horticulture application such as in gardens, farms, or potted plants.

If compost will be used directly from the machine, mix in a 10:1 (soil:compost) ratio, as the compost is highly concentrated. Alternatively, once the compost is cured for 4 weeks, it can then be used directly in horticulture applications.

Can the compost be put directly into my garden?

Compost can be used directly in your garden or plants. However, it is highly concentrated so it needs to be mixed with soil and used in the proportion of 10:1 ratio (soil:compost). Alternatively, once the compost is cured for 4 weeks, it can then be used directly in horticulture applications.

We recommending adding water into the machine.

The compost is very wet – what should I do?

We recommend adding some paper towels, or shredded paper, cardboard or newspaper into the machine.
