EXHIBIT C4: Solid Waste Audits

*This exhibit is provided to the Contractor as a guide to conduct a waste audit. The purpose of the waste audit is to:

• Identify cost-effective methods of achieving a minimum 50 percent (by weight) waste diversion.

• Support compliance with Guiding Principles for Sustainable Federal Buildings.

Extent of Work

Waste Composition The Contractor shall conduct a solid waste audit to identify the composition of the building’s non- hazardous, non-construction solid waste stream. As part of the solid waste stream audit, the Contractor shall examine a representative sample of solid waste (office trash) generated in the building (tenant space, lobby, kitchenettes/break rooms, printing rooms, bathrooms) during a 24-hour period of a typical workday. The Contractor shall use scales to weigh the sorted waste by the following material types: paper (all types of recyclable paper); cardboard;

plastic (#1 PET bottles and any recyclable plastics); aluminum/cans; glass bottles;

organic/compostable waste (food, food-related compostable packaging, paper towels); non-compostable, non-recyclable trash. The table below is provided as an example.

Waste Diversion Recommendations Based on the waste composition analysis, the Contractor shall provide recommendations for increasing the building’s waste diversion rate through cost-effective. efficient waste collection and disposal. The recommendations shall include:

• A list of currently acceptable and unacceptable waste materials for recycling (to include recycling codes, such as PET 1, 2, etc.).

• The building’s potential waste diversion rate, based on the waste composition analysis.

• A list of waste material types that could be added to the building’s recycling (and composting) program, based on the local recycling market.

• A narrative description of the current recycling, composting, and trash bin quantities, placement, and signage, and recommendations for improving signage and communication to tenants and custodial employees.
