  • Composting in Schools Initiative funded by Devon County Council (Successful bid to Investing in Devon Fund) Aim to assist schools in eight learning communities to develop appropriate composting systems as an educational resource by providing advice, education and equipment Supports the Dont let Devon go to waste campaign!
  • Slide 5
  • Composting in Schools Implementation of this scheme in each learning community aims to save approx:- 10,000/year 40 tonnes of waste/year 40 tonnes of carbon dioxide/year
  • Slide 6
  • Complements: Every Child Matters, Children and Young People's Plan, School Improvement Programmes; - Healthy schools, - Eco-Schools, - Food for Life Composting in Schools
  • Slide 7
  • Why compost in Schools? In the UK a primary school of 200 pupils produces 3 tonnes of waste each year, the equivalent weight of three rhinoceros. Across the whole country thats the same as 67,200 tonnes or a herd of 67,200 rhinos!!!
  • Slide 8
  • Why compost in Schools? Each school can reduce the amount of waste going to landfill by two thirds! Each school spends between 300 to 1000 on waste disposal each year. Millions of pounds are wasted on waste disposal!
  • Slide 9
  • Waste Audit Evidence School reduced waste going to landfill by 82%! Nearly all food waste now composted using in-vessel systems!
  • Slide 10
  • Scotspin composter
  • Slide 11
  • Slide 12
  • Ridan composter
  • Slide 13
  • Rocket composter
  • Slide 14
  • Scotty Hot Box
  • Slide 15
  • Scottys Hot Box
  • Slide 16
  • Achieving a good system Follow the four point composting mantra: Food Water Air Warmth
  • Slide 17
  • How it works Composting goes through four stages 1.First it gets warm 2.Then, if the mantra has been followed properly it will rapidly progress to being hot. Turning daily to mix and aerate as new food waste is added will maintain the temperature and will accelerate the composting process as long as fresh materials are being added.
  • Slide 18
  • How it works 3.Cooling. As long as the materials have heated up and are mostly broken down in the Scotspin, Ridan or Rocket they can be added to the maturation container (hotbox). *At this stage the material is only partly composted and it can vary enormously. 4. Maturation. Over a long period of time (between 6-12months) the compost can now mature.
  • Slide 19
  • Slide 20
  • Slide 21
  • Making it work! Daily tasks to maintain your composters: Collecting caddies Transferring food waste to Scotspin, Ridan or Rocket composter. Adding food waste to Scotspin, Ridan or Rocket and woodchip / wood pellets then tumbling or turning *Adult only to operate due to Health and Safety. Cleaning caddies and returning to stations / classrooms for use the next day What to do once your Scotspin is full: Once your Scotspin is full, it will need to be emptied into the Scottys hotbox and left to mature. *Health and safety issues need to be considered when transferring compost from tumbling system into Scottys hotbox.
  • Slide 22
  • Top tips 1)Add fresh materials daily do not leave waste hanging around in buckets/caddies getting smelly and attracting flies
  • Slide 23
  • Top tips 2) Always make sure you have the right mix of wet to dry materials fresh raw and cooked to dry woodchip/pelletised sawdust and mix well together 3) Wherever possible chop up whole fruit and vegetables or large items
  • Slide 24
  • 4) Tumble / turn and mix every time you add fresh materials
  • Slide 25
  • Top tips 5) - Leave enough space for tumbling to occur - Cardboard and paper should not be added to tumbling systems in any large quantity as they tend to absorb too much moisture, do not offer structure allowing air flow and tend to conglomerate into balls. - Its rare for the compost to be too dry but if it does seem to be too dry its better to try and add fresh green material than water.
  • Slide 26
  • Top tips 6 ) Line your buckets/caddies with some paper and or card to soak up liquids and make cleaning easier 7) Its easy to store dry woodchip, just cover it up in a bay or use a container. 8) Theres plenty of woodchip around, you could ask if any parents or governors have a tree surgery business and could supply you. Alternatively wood pellets are easy to use.
  • Slide 27
  • Top tips 9) Keep records of what you are doing e.g. amounts, weights, volumes, types of materials, observations of moisture, temperature and odour. 10) Observe what is going on and take steps to rectify any problems as soon as possible, this generally means adjusting the moisture levels or emptying the tumbler into the maturation bin. Dont panic! Compost happens!
