Pass-through waste and recycling

Sounds to me like this describes items as part of a business process and not items that would be conventionally understood as "waste" generated by the building. If that sounds right, I would say that these items do not need to be tracked. But I would be curious what anyone else thinks?

I agree - this waste is not generated at your project site and therefore would not be included in a waste stream audit.

Working with an HVAC Contractor / Mechanical Engineering firm to LEED their building. They take delivery of equipment packaged in cardboard and on pallets. They install the equipment on customer sites and return all packaging material to the building site for disposal. If we exclude discarded mechanical equipment brought to the site for specialized disposal, do we still need to audit the packaging material? Second, materials ordered and inventoried within the premises are also packaged in cardboard and shipped on pallets. Would the refuse created from these items be included in the audit? Third, subtenant is a mattress showroom and warehouse. Receives delivery of mattresses and returns old mattresses to the building for disposal. Is this considered waste attributed to business processes which can be excluded from waste audit? Thanks.
