Nunnington Hall is a picturesque Yorkshire manor house managed by the National Trust. Renowned for its exciting exhibitions and walled organic gardens as well as the excellent tea rooms. Organic compost for the gardens is produced on-site using a Ridan system to recycle food waste from the tea room, great for the environment and the vegetables.
This is what gardener Cailean Iain Stewart had to say about their Ridan.
“At Nunnington Hall we have been utilising the Ridan composter for about 4 years with great success. It is an efficient and reliable tumbler and has no problem coping with large amounts of kitchen waste. The finished product is very versatile; it makes an excellent pre-composter and helps as an accelerator in our home-made compost bays. It is also well beyond the interest of small mammals as well as being a sealed unit raised at height. It is the highlight of our ‘Clever Composting’ talks and always sparks intrigue from our visitors.” Cailean Iain Stewart

Because the Ridan can recycle food waste of all types, including a mixture of fresh and cooked, vegetables, fruit, meat, fish and dairy it is a very practical system for all catering outlets. Operating the Ridan takes just a few minutes every day, a highly visual and satisfying process which demonstrates sustainability and closed loop food production. No power is needed for the Ridan, so running costs are tiny. Despite this the mixture inside the Ridan will naturally heat up, regularly exceeding 60 degrees Centigrade even in the winter!

Excellent nutrition in every way is also part of the Stallcombe ethos, so the food is largely organic and much of it is grown on site, as such it is delicious and there aren’t many leftovers! But fresh food preparation creates a lot of trimmings which in turn create some fantastic compost which is used to enrich the soil in these wonderful productive gardens. Gardening and composting is a joint operation enjoyed by both staff and residents to the benefit of everyone.
‘The Ridan Composter is the ideal solution to our former problem of cooked waste disposal. It also fits in with our sustainable ethos within our community. Our residents supported by staff are involved with the process that is so beneficial to our environment. We are now looking to increase the amount of food waste inputted, which in turn will reduce the payback time to under three years. During our initial setting up Dan from Ridan was always available over the phone to help us resolve any hick ups we discovered. The composter has proved itself to be a very worthwhile investment. Well done Ridan!’
