MATERIALS AND RESOURCES
MR- P1: STORAGE AND COLLECTION OF RECYCLABLES To reduce the waste that is generated by building occupants and hauled to and disposed of in landfills. PREREQUISITE REQUIREMENTS Provide dedicated areas accessible to waste haulers and building occupants for the collection and storage of recyclable materials for the entire building. Collection and storage areas may be separate locations. Recyclable materials must include mixed paper, corrugated cardboard, glass, plastics, and metals. Take appropriate measures for the safe collection, storage, and disposal of two of the following: batteries, mercury-containing lamps, and electronic waste. POTENTIAL TECHNOLOGIES AND STRATEGIES Designate an area for recyclable collection and storage that is appropriately sized and located in a convenient area. Identify local waste handlers and buyers for glass, plastic, metals, office paper, newspaper, cardboard and organic wastes. Instruct occupants on recycling procedures. Consider employing cardboard balers, aluminum can crushers, recycling chutes and other waste management strategies to further enhance the recycling program. 62
MR- P2: CONSTRUCTION AND DEMOLITION WASTE MANAGEMENT PLANNING To reduce construction and demolition waste disposed of in landfills and incineration facilities by recovering, reusing, and recycling materials. PREREQUISITE REQUIREMENTS Develop and implement a construction and demolition waste management plan: Establish waste diversion goals for the project by identifying at least five materials (both structural and nonstructural) targeted for diversion. Approximate a percentage of the overall project waste that these materials represent. Specify whether materials will be separated or commingled and describe the diversion strategies planned for the project. Describe where the material will be taken and how the recycling facility will process the material.
