Frequently Asked Questions

Does it smell?

In Vessel composting technology is an aerobic composting method meaning oxygen is present and circulated within the process. There is an odour similar to a yeast smell which is contained with the composter. Sawdust/carbon pellets are also added to the process to absorb moisture and reduce odours. Rotten food waste smells and methane is typically generated when no oxygen is present ie in a biogas process or a closed static bin or bag.

What cooked food waste can be put in the machine?

All raw scraps and cooked food including meat, chicken, rotten foods, small bones. Pretty much everything produced in a kitchen. The only exclusions are milks, gravy and yoghurts. Naturally these cannot be composted and also requires too much additive to absorb excess moisture.

How much power do the automated machines use?

The JK5100 and JK6200 utilise approx 70-90kw of electricity per month.

Do you need skilled operators?

The Joraform technology is automated and requires very little skills to ensure the machine functions correctly. Full training to a number of operators will be provided including more in depth training to an overall project leader or manager.

Is this a full-time job?

No. The time allocated to each task is as follows.

Once or twice daily to insert food waste into the macerator chamber. Approx 5 minutes.
Every 2 weeks there is an emptying and transferring of chambers required. Total time allocated to this task is approx. 1 hour.
Replenishing pellet chamber when empty approx. 2 min. This task is usually done once per week.

How long will the machine last?

The Joraform machines if looked after and serviced correctly should run in excess of 20 years.

What else is added to the composting process?

Food waste has a high PH content and if not balanced with Carbon would burn your plants root systems and a really strong Amonia smell would be present. As part of the composting process a pine sawdust pellet is added to balance this high PH content, absorbs excess moisture and reduces odours. The sawdust is also a source of nutrient for the microbes that are busy at work decomposing the food waste. All life forms require Carbon and microbes are no different. The approx. carbon additive is 8%.

Is it ready to use after four weeks?

Yes. No further maturing is required.

How much compost will it produce every month?

Depending on the size of the machine installed but as a general rule output is approx. 50% of waste input.

Does it attract flies?

Due to the high temperatures generated inside the machine in excess of 60 degrees Celsius. These temperatures coupled with machine rotation, microbial activity and heat due not make for a fly friendly environment. The external parts of the machine should be regularly cleaned though.
