Composting Machine Technology Q&A: Energy Consumption, Water Consumption, and Automated Operation & Maintenance Records

As households and communities increasingly seek sustainable solutions for organic Waste Management, in-home and commercial composting machines have gained significant attention.

Most home and small-scale composting machines are primarily high-temperature dehydrators + shredders, not true composters. They work by:

• Heating the waste (often to 60–100°C or higher)
• Continuously stirring and ventilating
• Rapidly evaporating water (reducing weight by 70–90%)

The result is a much smaller volume of dry particles or powder that looks like fertilizer. However, this is not fully fermented compost — it is pre-treated, dehydrated organic material. The microbial decomposition is only partial and incomplete.

What a real composting machine should be? A real composting machine facilitates actual aerobic biological decomposition by microorganisms, producing stable, nutrient-rich compost (humus-like material) that improves soil structure, retains water, and supports plant growth.

The Q&A of this composting machine is based on actual usage records and challenges encountered during daily operation - specifically focusing on energy consumption, water usage, and the effectiveness of automated operation and maintenance.

1. What other input do you need for this machine? Wet waste is the major input, but do you have to input any dry waste: like cardboard/sawdust or anything like that?

A: No. When startup/commissioning, we will offer some biological agent, then no other materials needed, and such biological agent is easy to get.

2. What is the water/energy consumption of the machine?

A: for reference: Energy 120kwh for per ton of water, water <100L for per ton of water. Water is just for washing the inlet to ensure no residual waste remaining in the corners/dead zones.

3. How many staff does one need to operate the machine?

A: One part-time operator. The machine runs automatically. The staff is just for loading and unloading .

4. How skilled should you staff be?

A: No special skills required.

5. Do you provide assembly assistance?

A: Yes.

6. What other consumables does the machine need to run?

A: No other consumables needed. The biological agent is easy to get and free of charge. Unless the machines stop running for over 7 days, no need to input new.

7. What is the lead time, after an agreement has been reached to delivery?

A: 4-5 weeks.

8. Who assembles the machine, does it need to be assembled?

A: No need for assembly. But pipe and cable connections are needed. If you could not finish this according to the guidebook or video, we could send someone to guide.

9. Will you provide maintenance training locally?

A: Yes.

10. Are parts available locally? i.e. do you use standard/known/brand name parts for bearings, motors, PLC, breakers, microcontroller HMI, etc.

A: All components are standard parts except the blades of the crusher/shredder. If metal or other hard objects are frequently mixed in the input waste, it may cause damage to the blades. We will provide some free spare parts and train you on how to replace them.
