The rule of thumb is: anything a human can consume, raw or cooked, can be placed into the machine.

Anything that is not organic - for example, plastic, glass, metal products. Putting these items into the machine can potentially lead to machine damage and malfunction.

Small sized bones, like chicken bones and fish bones can be put into the machine. Large swine bones, lamb shank bones or cow bones are not recommended.

Only soft seafood shells can be put into the machine like shrimp or prawn shells. Do not put lobster, crab, mussels or clam shells into the machine as it will not break down due to its high calcium level and can potentially cause damage to the machine.

The machines can handle a small amount of yard trimmings like grass and leaves. It is not recommended to add plant roots as it can wrap around the machine's axis and blades.

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

No. Oklin's Composters comes with a proprietary starter material pack that will regenerate itself continuously during the composting process.

Yes, if it is certified compostable products. For example, North American compostable products must display the BPI Certified logo. Please note that these products will take longer than 48 hours to compost. Compostable goods input should also be no more than 10% of daily capacity

On average, compost will need to be offloaded from the machine once a week, when the machine is used at full capacity.

No. Oklin's proprietary microbes used in the compost machine are only active in high temperatures of 55° Celsius or higher, and require oxygen to survive, so they do not pose any threat to humans.

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.

No. Oklin's 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.

Food waste dehydrators often require sewer hook up. Oklin's composters do not require hook up to sewer line, as the steam generated from the composting process is extracted and absorbed by our deodorizers.


The output from dehydrators have the same characteristics of dried up food waste, and is not recommended to be used as soil amendment. The compost from Oklin's machines are a nutrient rich material that can be used in gardens.

Food waste digesters require water supply and access to drain or waste water 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. Oklin’s 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 replenishing, while Oklin’s microorganisms self-regenerate, and does not need to be replaced.
