On-site food waste recycling made easy
The Ridan Pro system consists of a Ridan Pro composting machine and a set of maturation bins.
Capable of processesing up to 400ltrs (200KG) of food waste per week, the Ridan Pro System is perfect for:
- Schools, Colleges & Universities
- Hotel & Restaurants
- Residential & Care Homes
- Commercial & Industrial premises
- Estates and Land Management
- Agricultural businesses
- Garden centres
- Holiday parks
Simple and free to run, the Ridan Pro composting machine is a hot, aerobic constant throughput composter, which is capable of dealing with all types of food waste and bio-degradable green waste on-site.
Designed and built in Devon, the Ridan Pro composting machine is made from weather-proof, robust materials and is covered with an insulated jacket to help retain the heat produced by the natural composting process.
The Ridan Pro does not require any power so can be positioned anywhere. Compost requires Nitrogen, Carbon and Oxygen to work. Nitrogen is provided by food waste, carbon by wood or cardbaord and oxygen is supplied by turning a manual, mechanical handle which introduces air into the mixture.
EasyGear Technology is Ridan’s solution to making composting as easy as possible. The mixture inside the composter requires aerating and is turned by a series of blades, but the mixture can become quite heavy when the composter is full. The EasyGear is an ingenious use of engineering technology that makes use of a cog and gear system to make turning the blades easy.

The compost that emerges from a Ridan composter will have completed the hot thermophilic stage of composting, but in order to become a good growing medium it must be matured for a further 2 or 3 months before use.
For the maturation process you will require maturation bins.
The Ridan Pro 900 is a maturation bin designed and built to compliment the Ridan Pro composting machine. We recommend three maturation bins for the Ridan 400 and two for the Ridan Pro 200.
The Ridan 900 Maturation Box is a robust 970 litre compost bin with steel base constructed from tough insulated plastic. It has an easy-open secure lid on top and compost removal hatches at the bottom.
Complete with a steel base and metal sides to keep pests (such as rodents) at bay, it is simple to assemble and ideally suited to maturing the compost after it has been through the Ridan. It is approximately 1m x 1m x 1m.
During the winter, the warm compost can be a very attractive nest site for squirrels, rats or mice. The Ridan 900 compost maturation box has been carefully designed to be completely pest-proof, with a metal base and sides.
Keep rodents and pests at bay
A carefully designed arrangement of ventilation slots and channels feed and extract air from the compost, these also provide access for bugs, beetles, worms and all the creatures that really do the work for you, see our composting page for details.
if you require a compost thermometer to check the temperature within your Ridan or Maturation Bin, we stock accurate long probe units which are easy to read. They are quick to use and indicate the ideal temperature for fast composting.
Thermometer Cost – £25 plus VAT each.
