  • CUSD is committed to recycling and diversion of waste products from our landfills.  In addition to mixed recycling and green waste composting diversion at all sites we are prepared to participate in the organics composting when readily available to us.  In addition to these steps we also have active programs in place to address electronic waste, lamp and battery recycling, metal recycling, tire recycling and hazardous waste products.
  • The diversion rate is measured in both yardage to account for the volume of space diverted and by tonnage to account for the weight diverted

  • The diversion rate for CUSD through the 2nd Qtr of 2021 is 60.04% by yardage and 54.19% by tonnage.



The Healthy Schools Act of 2000 was signed into law September 2000 and requires that all schools provide parents or guardians of students with annual written notification of expected pesticide use on school sites when children are not present.  Notification will identify the active ingredient or ingredients in each pesticide product and will include the Internet address for further information on pesticides and their alternatives.  We will send out annual notifications in September of each year.
