The AIMS Games are making records on and off the field with organisers aiming to divert 60 per cent of the games' waste away from landfill this year.
For the fifth year, Waste Watchers are on board and have set themselves the biggest goal yet, with the help of 40 local students.
Waste minimisation adviser Hope Lawsen said they had met their waste diversion targets for three years of the past four, increasing their target each year.
The focus was on recycling and composting as much waste as possible, sending the smallest possible amount of waste to landfill.
Miss Lawsen encouraged supporters and spectators to take packed lunches in reusable containers instead of cling wrap and to take reusable drink bottles that could be filled at the grounds.
