Compost all your food waste with a Big Ridan composting machine.
Suitable for commercial kitchens, cafes, restaurants and large schools.
The same simple easy to use Ridan, its just bigger and capable of composting even more food waste and if 400 litres per week is still not enough then why not use two or three big Ridans, still great value and free to run.
Simple and free to use, the Big Ridan is a hot, aerobic constant throughput composter, which will deal with all food waste on-site, quickly producing rich compost for the garden.
Remove the lid and tip in the food waste, add the same volume of woodchip, turn the handle, replace lid.
Repeat daily, as the handle is turned compost will emerge from the outlet.
All food can be composted, raw or cooked including meat, fish, dairy and eggs.
On-site aerobic composting locks carbon back into the compost where it enriches the soil, creating ideal growing conditions for more food, completing the cycle in a natural way.
Ridan dimensions – 2.4 meters long, 1 meter wide and 1.7 meters high.
Capacity – Ridan can process 400 litres of food waste per week.
Requirements – Can be sited outside, no services or power required zero operating costs.
Cost - £3,400 plus delivery and VAT. Or lease/buy from £165 per month over 2 years (grants may be available).
It works like this - The lid (white part) is removed so that food waste can be loaded, the same volume of woodchip, sawdust or wood shavings must then be added. Then turn the handle for about ten turns, this mixes the contents and allows air to penetrate the mixture creating the perfect conditions for composting microbes to respire. As the microbes work they create heat which the insulated body of the Ridan retains, creating a humid hot climate within, perfect composting conditions meaning that the composting process takes as little as 14 days. The mixture travels through the Ridan when the handle is turned, eventually emerging from the open outlet. The whole process takes 5 minutes per day.
