Composting food waste through the use of Oklin’s in-vessel composting machines is not only easy to use, but provides user with a hands off experience.
- What can I put into the machine?
The rule of thumb is: anything a human can consume, raw or cooked, can be placed into the machine.
- Can I put meat and dairy products into the machine?
Yes - there is a hygienization function on the machine that heats the unit up to 70°C for 60 minutes to kill any harmful pathogens and bacteria such as escherichia coli (e. coli) and salmonella so that the compost is safe to use as fertilizer.
- What cannot be put 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.
- Can I put bones into the machine?
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.
- Can I put seafood shells into the machine?
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.
- Can I put yard trimmings into 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.
- How often can I put food waste into the machine?
We recommend adding food waste into the machine once a day for ease of operation and allowing a full 24 hours before adding more food waste in.
- Do I ever have to replenish the bacteria culture?
Yes, we recommend replenishing the Acidulo microbes on an annual basis to optimize the strength of the microbes.
- Can I put compostable products into the machine?
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.
- How often does the machine need to be emptied?
On average, compost will need to be offloaded from the machine once a week, when the machine is used at full capacity.
- Are the microbes harmful to humans or animals?
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.
- 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?
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.
- How are Oklin composters different from food waste dehydrators?
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.
- How are Oklin composters different from food waste digesters?
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 multiple times a year, whereas Oklin's microbes only need to be replaced on an annual basis.
- How are Oklin composters different from other food waste composters?
Oklin's composters turn food waste into compost in 24 hours using our Acidulo microbes, whereas other composters on the market generally require at least 7 days and bulking agent (carbon source) such as sawdust, wood chips or paper towels for food waste to begin composting.
- Do you provide compost pick up service?
Please contact your local distributor for more information.
- Do you provide machine maintenance service?
Please contact your local distributor for more information.
- What can I use the compost for?
The compost can be used in any horticulture applications, for example, 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?
Yes. The compost can be used directly in garden or plants. However, as it is highly concentrated 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.
- The compost is very dry - what should I do?
We recommend adding water and food waste 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.
- The compost is high in oil - what should I do?
We recommend adding some shredded paper or paper towels into the machine.
