Reduce classroom waste

Energy waste

Tips to conserve energy at your school include:

  • sensors – don't place thermostats near heat sources such as photocopiers, vending machines, refrigerators, lighting, sunlight and heaters. If an air-conditioning sensor is over a heat source, the system will operate for longer and use more energy than necessary
  • time controls – use time controls for your school's heating and air conditioning. For example, start the central heating 30 minutes before the children arrive at work and stop it 30 minutes after they leave
  • lighting - check that full lighting is not being used unnecessarily outside normal school hours. For example, cleaners may need only partial lighting when working. Light switches could be colour coded for different activities
  • switching – break up large areas of lights that are on a single switch into separately controlled areas, particularly areas near windows and partitioned off rooms. This enables lights to be switched off when they're not needed
  • put light switches where people can find and operate them
  • form a student ‘energy patrol’ to ensure lights are out when rooms are empty. Set targets and remember friendly rivalry can achieve great things
  • have students make signs and stickers to remind people to turn off the lights when they leave a room
  • have students conduct an experiment in classrooms by turning off selected banks of lights and surveying occupancy comfort at different lighting levels (often, occupants prefer working under natural light)
  • use energy efficient compact fluorescent light bulbs (CFLs) and light-emitting diode (LED) bulbs. Make this a learning experience by asking students to calculate the energy savings achieved by: 
    • replacing incandescent light bulbs with CFLs 
    • changing incandescent lights in ‘Exit Signs’ to light-emitting diode (LED) bulbs
  • don’t block the airflow around vents. Keep bookcases and other bulky items away from the heating (and cooling) units so they don’t block the warm (or cold) air that should be coming into the room
  • in areas like the cafeteria that has peaks and troughs of use, install programmable thermostats so they are only regulated when they are being used
  • turn down heat in the hallways and keep classroom doors closed, otherwise, the heat is just wasted into the halls and even to outside
  • get students to search out draughts and fix them with creatively crafted insulators
  • always turn off your computer monitor when away from your desk for 15 minutes or more – especially including during your lunch break and meetings 
  • when you go home, log out and turn off your computer and monitor and accessories at the power switch
  • switch off photocopiers and printers at night 
  • purchase electrical equipment with a high energy saving value ​

Water waste

Water is essential to everybody’s lives and should be used sparingly and never wasted. There are many ways for schools and their pupils to be proactive in discovering more about water, how it is used in schools and how to protect and conserve this important resource. Simple actions can be taken by schools to monitor, conserve and involve students in water protection these include:

  • finding out where water is used in the school
  • monitor the schools water use
  • decide on a water action plan – how water can be conserved
  • make the appropriate changes to conserve water
  • encourage pupils to take a responsible attitude towards water use
  • require students to utilise their knowledge on local, national and global water issues

Conserving and protecting water in schools will not only preserve this essential resource but can also reduce school costs.  It has been stated that a school of 600 pupils could reduce water costs by up to £5,000 per year.

School lunchboxes

  • replace brown paper bags with a reusable lunch boxbag stainless steel food containers
  • switch from disposable paper napkins to reusable cloth napkins
  • give up the habit of disposable water bottles and replace it with a reusable stainless steel water bottle
  • skip disposable plastic cutlery and pack reusable spoons or forks
  • save money by avoiding individually wrapped or packaged items like yogurt, cheese, cookies or crackers.  Buy larger sizes and pack portions in reusable containers
