Depth of data collection required

Yep, to comply with the credit requirements, you only need to document the total amount of waste generated during the performance period and then specify the amount of recycling that occurred during the same period. You don't need to provide hauler receipts, but it is a good idea to try to separate out the different types of recycling (i.e. glass, plastic, cardboard, paper, etc.) and note who the hauler was for each type of recycled material. You can easily track the amount of recycled material by using the Waste Management Tracking Sheet for Ongoing Consumables located in the Documentation Toolkit section; if you use this tracking sheet throughout your performance period, it should be a snap to complete the LEED Credit Form and include detailed recycling info.
