Making the world a better place

Most of our composters are delivered to businesses and organisations wishing to reduce food waste collection costs and make their business more sustainable, but every now and again we deliver a composter to a site run by passionate volunteers all working hard to enrich each other’s lives and just make the world a better place.
These include:

  • Community gardens
  • Community farms
  • Community cafes
  • Residents associations
  • Shared allotments

Pentrebane zoneOne such example is Pentrebane in South Wales where residents and volunteers have been recognised for their great community work at the Pentrebane Zone which includes Gardening Clubs, Family Cooking and Woodworking workshops, winning several awards along the way.

The gardening club includes a scheme to grow your own hops before supplying then to a local brewery who turn them into excellent, low food-miles beer, a great way to enjoy the fruits of your labours, now that is keeping it local!

All the green waste, food waste and shavings from the woodworking workshops can now be added to their community Ridan Composter, to be turned into lovely, healthy, nutritious compost for use in their community gardens. It’s a win win for the members and the environment.

What is composting?

Composting is the decomposition of biodegradable organic matter, including cooked and raw food waste. Kitchen waste and plate scrapings can all be composted, as can garden waste such as grass clippings and dead leaves. Any bio-degradable matter can be composted.

When the conditions in the Ridan composting machine are correct, microscopic organisms respire and breakdown the matter to produce nutrient rich compost that is perfect for your garden!

What can your community group compost?


  • Fruit and Veg (including skins)
  • Meat & Fish (raw and cooked)
  • Plate scrapings, anything edible.
  • Grass cuttings and garden waste
  • Shredded paper, card and tissue
  • Oils and fats
commercial food waste composting

All raw and cooked food waste can be composted in a Ridan. Fruit, veg, greens and prep compost most easily, however starches, meats and dough take longer to digest, much like our own digestive systems, so a mixture of both types of foods is essential.

Dead leaves, straw, paper, cardboard and tissue can be composted by layering them into the Maturation Box, between the compost as it is loaded, this works better than adding them to the Ridan. For more information go to: How the Ridan Composter works
