Projects may achieve Feature 22, Part 1 by using uncovered trashcans if they are located directly underneath paper towel dispensers and at least one closed trashcan is additionally provided to collect waste other than paper towels. This does not apply to trashcans located in areas where food is prepared and stored (e.g., kitchens, pantries, etc.) as these recepticles must be closed to avoid pests.

In bathrooms, projects may use garbage or recycling cans without lids that are designated for only paper towels so long as there are nearby garbage cans that meet the feature requirements.

When desk bins are used to comply with Feature 22, Part 1, Requirement b, waste must be emptied at least once per day. Bins must be lined with appropriate liners (e.g. biodegradable liners for the compost bin) that will sufficiently retain all waste and waste residue. Bins must be wiped to remove waste residue when present or at least weekly.
