Who uses the Ridan Compost Box

  • Domestic home use
  • Small shops and businesses
  • Allotments


Both composting machines feature sturdy, stainless steel cases so they can withstand the weather and prevent infiltration from rodents.

They are both insulated with a 3cm thick foam casing that enables the compost to warm up and stay warm, all through the year.

The heat in the upper layers accelerates the composting process, then bugs and worms in the lower layers produce the finished product.

An underfloor aeration system draws air in to the mixture whilst allowing access for worms, bugs and microbes.

Other features include:

  • Adjustable air inlet valve
  • Fluid outlet drain
  • Air inlet for option pumped air
  • Rodent and vermin proof casing
  • Water / weatherproof, long-life stainless steel casing
  • Underfloor aeration system

Clever design

Cleverly designed air vents draw fresh air in and keep the rain out, whilst maintaining the warm temperature inside.

A lid at the top makes it easy to throw your food waste and green waste in and a harvesting hatch at the bottom enables you to draw your compost out.

The Ridan Compost Box does not require any power so can be positioned anywhere in your garden.

What can be added to the compost?

You can add any bio-degradable matter to the composter. That includes veg, meat, fish, egg shells, in fact any food substance, cooked or raw. You can also add green waste from the garden.

The important thing is to create an equal balance of nitrogen (from the food and green waste) and carbon (wood chippings, pellets or sawdust). This balance together with oxygen from the air is what creates the perfect environment for the composting process to begin.

Worms, bugs and microbes then move in to finish the process by breaking down and filtering the compost. After a three month period of maturation, your compost will be ready to use.

Organic, peat-free compost

Your home-made, organic and peat-free compost can be produced in as little as three months, however the longer it is left, the better it gets as it continues to mature.

The Ridan Compost Box is the perfect solution for environmentally conscious people who want to help reduce greenhouse gases and be responsible for their own waste at home.

You could even grow your own food at home and complete the full eco life-cycle!

Why buy a Ridan Compost Box composter?

While composting takes place naturally, it is not always easy to get the conditions just right all year round. A compost heap, or cheap, plastic composter will allow the mixture to get wet or cold, slowing or even stalling the process. Our insulated, thermal Compost Box range ensure the conditions are right all year round.

There are other thermal insulated composters on the market, but they often do not allow for air flow in or fluid flow out which can hinder the process.

At Ridan, we have tried and tested all of the top-selling composters and set out, not only to improve on their existing features, but to add new, innovative features that only exist on Ridan products.
