This gave plenty of opportunity to comply with if not exceed, the commitments of the Environmental Guidelines. However, recent test events have given cause for concern about the level of contamination of 'recyclables' and it is not yet certain the system will reach high standards of waste separation. Waste minimisation at the Sydney Olympic Games Waste minimisation efforts for the Sydney Olympic Games can be broken into 2 categories - facility construction and facility operations. OCA is also responsible for minimising waste during the Olympic Games outside the secure perimeters of Olympic venues and at railway stations, bus interchanges and at park and ride centres for public transport. To support this system, strict input-controls are in place inside Olympic venues.
Most packaging is recyclable or biodegradable.
All disposable cutlery, straws, and cup lids are made from cornstarch and plates are made from sugar cane. These can all be composted. Drinking cups and wineglasses are made from PET plastic which can be recycled along with glass, aluminium, steel and liquid paper board. The obstacles are bin infrastructure and public education. The difficulties in obtaining information made it unrealistic to definitively rate sponsor performance.
