our hotel project already has in place a rigorous waste diversion programme, where 80%+ is diverted from landfill. we have daily to bi-weekly to weekly and monthly records which give us very good visibility on materials diverted, such as (with apologies for the detail):

Cardboard K4, Compostable materials, Fat/ vegetable oil, Food Waste, Garden Refuse, Glass, Metal cans, Paper common mix, magazines, newspapers, white paper, Plastic PE-HD, Plastic PE-LD, Plastic PET, Plastic PP, Plastic PS, Plastic PVC and Tetrapak.

Our team's question is whether we still need to run a full waste audit on the above items over the audit period or whether a full audit on the waste usually destined for landfill will be sufficient?

Many thanks!
