On-site Composting Apparatus (OSCA)

The University's OSCA composting machine transforms organic waste into nutrient-rich compost for the campus gardens. OSCA can process the following:

  • All food scraps
  • The compostable plates, cups and cutlery sold at campus food outlets
  • Paper hand towels
  • Cardboard

Some of the key benefits of using OSCA include:

  • Very low energy consumption to run the machine
  • Silent processing of organic matter
  • Produces odourless compost
  • Diverts organic waste from going into landfill
  • Reduces transport costs of waste going to landfill
  • Educates people about composting
OSCA facts
  • At capacity, 50 tonnes of organic waste a year can be processed by OSCA. This represents a reduction of 60 tonnes of CO2 entering the Earth's atmosphere every year at Sippy Downs.
  • One wheelie bin full of compostable waste takes 2 weeks to be processed by OSCA into rich compost.
Compostable catering supplies
  • To ensure the organic waste stream is consistent with OSCA's requirements, compostable catering products (i.e. made of 100% corn starch) such as cutlery, plates and coffee cups (including lids) are used in all food outlets on campus. Compostable catering products are a significant factor in the success of the waste recovery program and has helped the University convert 25% of its food waste to rich nutrient compost each year.
