School food waste composting with Gary Nixon

Thanks for the delivery of the Ridan composter, today.
I am extremely excited to introduce this marvelous machine to St Leonard's Primary School. I have used them in two previous schools and they have worked wonders. After a school waste audit (carried out by Resource Futures) in my last school, it was highlighted how much of our compostable waste was thrown into the general waste bin. With the Ridan, not only did we reduce the weight of waste going to landfill, we created some fantastic compost to help enrich our flower beds. The children loved being part of the whole process and and felt proud when organic gold was being produced and put back into the growth cycle.
Long live the Ridan!

Hot Steamy Stuff !

Composter is working really well. The pellets definitely work better than regular sawdust/chippings.
The sight of steam coming out of it when I crank the handle is more satisfying than it ought to be!

Damers First School and Dorset Waste Partnership

Following a recent visit Karyn Punchard, Director of the Dorset Waste Partnership, said:

“It was great to see how Damers First School has incorporated the Ridan food waste composter into their outstanding eco-friendly practices. While the Dorset Waste Partnership operates a kerbside food waste collection service, we always emphasise how composting is best for the environment and the public purse. By recycling their food waste on the school site in a clean and convenient manner, Damers First School is not only saving money but helping to educate pupils and their families about the environment. Well done to everyone involved.”

Rooftop food waste composting in Birmingham.

I’m really impressed with the Ridan.  We are putting through a steady flow of kitchen waste and bits and pieces.  We’ve settled on using the sawdust pellets as a carbon source.  I tried to shred our own cardboard, but couldn't come up with an efficient, economic shredder which could handle our cardboard waste, so I’ve settled for the pellets right now, which are easy to use and store.
The Ridan is powering away, cruising at anywhere between 45-55 centigrade.  What really impresses me with the design is the combination of robustness and providing the appropriate biological operating conditions.  The gearing on the tumbler shaft really makes turning practical.  The chimney effect drawing air through the chamber works well, and the insulation allows for maintaining good temperatures.
We have already had some output, for 2-3 weeks now, which comes out a nice consistent semi composted mass, which we are feeding to our worms in the basement.  The output is almost odourless, and stabilised enough that I am confident that it won’t attract rodents in our basement – so all around I’m very happy. 
So thanks for your great Ridan – it’s already become a much loved colleague.

Office food waste composting at the Intellectual Property Office.

'We have been running for a few months now, the first compost has just started coming through the machine and I am really pleased with its quality and the speed with which it has composted.  The waste in the Ridan is much hotter than the waste we used to hold in our old tumblers, you can now see the water vapour rising from it as soon as you lift the lid off.  We are not hitting the 50 degrees plus suggested on your website, possibly because at the moment we are using well decomposed leaf mould rather than wood pellets as the carbon component.  This might also explain why the compost is coming out wetter than it probably should.  But as I said the compost produced by the Ridan is good stuff (despite not operating under optimal conditions), will dry off in the finishing container and we are saving money and being greener by not buying in wood pellets.'

Barclay Primary School composting

Barclay Primary School

I have two children that come daily to help with the compost.They really enjoy coming and find it very easy to use.
We normally put around one bucket of food waste in each day but this can vary slightly.Recently we noticed that it was coming out quite dry so we put in a little less sawdust, we will have to wait a week or so to see if this has made a difference.
I am also going to start a gardening club during which we will be using the compost, so the children will help out with this too.

Riverford Organics

As a organic business it’s important that we and our customers have a better understanding of waste. Food waste that goes to landfill is bad for the environment; it causes methane production and if not managed correctly can contribute to global warming.
So when we were looking at purchasing a composter to reduce waste going to land fill Ridan seemed the best company to work with. The service we have received has been truly professional, any problems we have encountered they have resolved almost immediately.
So when it comes to ‘creating a closed loop’ system and benefiting from the opportunities we can create from sharing this with our customers then we all should work with Ridan.

Channings Wood Prison

By installing the Ridan Composting System, not only have we raised awareness of how much waste we produce on site, we have also created a keen interest in how best to reduce or recycle it. The Ridan has created a big stir and captured a keen following amongst both inmates and staff due to its simple yet very effective operation. Financially the Ridan system will pay for itself within three years, but morally it is priceless’
