Eco-Friendly Solutions for food recycling  for schools & colleges

Food waste composting for schoolsRecycling food waste produced by schools and colleges with a Ridan composter is not just an environmentally practical solution to an ongoing problem, it is also a fantastic way to educate pupils about composting and recycling; providing them with hands-on experience of sustainable living.

All raw and cooked food waste can be turn into recycled compost using a Ridan food waste composting machine – fruits, vegetables, meat, eggs, fish and dairy products . So long as school has some gardens or grounds, you can compost all of your food waste onsite, as soon as it has been discarded.

How to recycle your school food waste

It is now possible to recycle all common school food waste products. What’s more, food waste (and all green waste such as grass clippings etc) can now be recycled on-site, without producing any environmentally damaging emissions with a Ridan food waste composting machine.

The compost produced by the Ridan can then be used to enrich the school soil – allowing carbon consuming plants to be grown. It’s win win situation for both the school and the environment.

What size composter do I need?

School Food waste recycling machine
We offer a range of three Ridan Food Waste Composting Machines, to accommodate schools and colleges of all sizes.

The best way to decide which size of Ridan you need is to measure how many litres of food waste are produced by your school each week;

  • If you’re producing less than 80 litres, we recommend the Small Ridan
  • If you’re producing between 80 and 200 litres, we recommend the Medium Ridan
  • If you’re producing between 200 and 400 litres, we recommend the Large Ridan,
  • If your school produces over 400 litres, we recommend you consider using two Large Ridans.

What if I don’t know how much waste my school produces?

If you’re not sure how many litres of food waste you’re discarding each week, here’s a general guide:

Of course, please remember that other factors need to be considered too, such as:

  • How efficient are the school/college kitchens?
  • How much fresh produce is prepared on site compared to how much is bought in?
  • What sort of foods are being thrown away? Vegetable matter, fruit and greens compost easily and quickly, but meat eggs and dairy take longer.

How long does compost need to mature before using on the garden?

Food waste composting for schoolsThe fresh and nutritious compost that emerges from the Ridan should be matured for 2-3 months before being used on the garden. Whilst maturing, the compost needs to be stored in a suitable maturation bin, such as the Ridan Maturation Box.

Usually these bins are used in pairs – one to be filled daily, and the other full and left to mature. Once the full bin has been harvested, simply swap the two around.
