LEED Construction Waste Management Guide: Diversion and Tracking
LEED Construction Waste Management Guide: Diversion and Tracking
The construction and demolition sector produces hundreds of millions of tons of waste globally every year. Within the Materials & Resources (MR) category, LEED mandates strict protocols to divert these materials from landfills. Earning these credits requires detailed pre-planning, active on-site sorting, and the collection of haulers' records.
This step-by-step guide outlines the requirements for drafting a Construction Waste Management Plan and capturing points for landfill diversion.
1. Core Prerequisite: The Waste Management Plan
Before any diversion credit is reviewed, the contractor must satisfy the mandatory **Construction and Demolition Waste Management Planning** prerequisite. This requires drafting a plan that identifies at least five targeted materials for diversion, specifies on-site sorting areas, and designates local recycling facilities, as discussed in LEED Prerequisites Explained.
2. Earning points through Landfill Diversion
Projects earn points based on the percentage of total construction waste diverted from landfills. This requires establishing at least three or four distinct waste streams (e.g. wood, metals, concrete, cardboard):
- Option 1 (50% Diversion): Divert at least 50% of the total waste across 3 material streams (1 point).
- Option 2 (75% Diversion): Divert at least 75% of the total waste across 4 material streams (2 points).
3. Meticulous Tracking & Audit Evidence
GBCI reviewers require audit-grade proof of waste diversion. The contractor must maintain a monthly log showing waste quantities, sorting receipts from recycling plants, and photo logs of on-site bins. For tracking guidelines, refer to LEED Documentation Requirements.
Additionally, incorporating materials with transparent product certifications supports separate MR credits. Learn more in our guide on LEED EPD Requirements Explained.
Frequently Asked Questions
What is a Construction Waste Management Plan in LEED?
It is a mandatory planning document detailing how a project will divert at least five key material streams from landfills, identifying local recycling partners.
How many points can you earn for waste diversion?
You can earn up to 2 points for diverting construction and demolition waste (50% for 1 point, 75% for 2 points).
What counts as a waste stream in LEED?
A waste stream is a specific material category (e.g., concrete, wood, drywall, cardboard, metals) that is separated and tracked individually for recycling.
Are hazardous materials included in the waste diversion calculations?
No. Hazardous materials, such as asbestos or chemical waste, are excluded from the calculations as they require specialized disposal by law.
What records must be submitted to verify compliance?
You must submit waste haulage logs, weight tickets from sorting facilities, and photographs of the designated waste separation bins on site.
