Commercial Composter
CR-30 Food Composting Machine
30 kg/day composter for restaurants, schools and offices
CR-30 takes 30 kg of food waste per day through a 110 L composting chamber and returns organic fertilizer within 12 to 24 hours. It is the size most single-kitchen restaurants and school canteens land on: 2 kW on a 220 V single-phase supply, 300 kg, and a 1100 x 730 x 1200 mm footprint that fits against a back wall. Microbial decomposition cuts at least 85% of the incoming volume, so what leaves the site is a fraction of what arrived in the bin.

What it solves
- A restaurant kitchen filling several bins a day with plate and prep waste
- School canteens with a fixed collection contract and rising volumes
- Odour and pest complaints from a shared bin store
- No practical route to on-site organics diversion without civil works

Who it is for
Single-kitchen operators in the 30 kg/day band who want waste handled where it is produced, on the power supply they already have.
Where it is used
- Standalone restaurants serving a few hundred covers a day
- Primary and secondary school canteens
- Corporate office kitchens and staff restaurants
- Small hotels consolidating breakfast and restaurant waste
Quality control
Each CR-30 is run under load before shipment. Stirring torque, chamber temperature behaviour, deodorisation and the fault alarm chain are all verified, and the unit ships with the specification sheet for its serial number.
Customisation
Supply voltage, brand marking, control panel language and export crating are configured per order. Where a site has heavy oil content, the CRO-300S separator is quoted alongside.
How it is operated
- Install indoors against a wall with service clearance
- Charge the microbial medium at commissioning
- Load waste through service periods up to 30 kg per day
- Let the automatic cycle run 12-24 hours
- Remove organic fertilizer on the agreed interval
- Replace carbon media and check UV at scheduled service
How it compares
CR-30 doubles the chamber of CR-10 while staying on single-phase power. CR-50 is the next step at 50 kg/day and 180 L; beyond 100 kg/day the range moves to 380 V three-phase machines.
Frequently asked questions
How many covers does 30 kg/day cover?
It depends on menu and plate waste, but CR-30 is the size most single-kitchen restaurants and school canteens specify. Send us your daily bin weight and we will confirm.
Does it need three-phase power?
No - 2 kW on 220 V/50 Hz single phase.
Can it take bones and cooked food?
The machine is designed for mixed food waste including cooked items; very hard bone should be kept out.
How often is the output removed?
On the interval set at commissioning - the chamber holds a working volume rather than needing daily emptying.
What maintenance does it need?
Routine checks of the deodorisation media and the drive, both covered in the commissioning notes.
How loud is it?
It is designed for indoor installation in occupied buildings, with stirring cycles rather than continuous high-speed motion.
What if we grow past 30 kg a day?
CR-50 and CR-100 keep the same single-phase installation approach with larger chambers.
