Construction projects generate enormous amounts of waste. According to the U.S. EPA 2018 Fact Sheet, construction and demolition activities generated over 600 million tons of waste in 2018 with nearly 145 million tons sent to landfills. The industry is uniquely positioned to drive environmental change. With the release of LEED v5, the expectations around construction waste management are evolving to push the industry forward.
Understanding waste management will help project teams meet LEED v5 certification goals and support a more sustainable built environment.
Waste Management Headaches
At Green Badger, we’ve heard countless stories from project teams with the best intentions who still fell short of their waste management goals. Managing construction and demolition (C&D) waste is often one of the most challenging sustainability efforts on a jobsite.
Despite good intentions, several real-world obstacles stand in the way of effective waste diversion like:
- Limited space on jobsites to stage multiple waste streams (i.e. wood, gypsum, etc.)
- Lack of local vendors that accept commingled and/or source separated materials
- Onsite separation challenges, where team members incorrectly manage material disposal (i.e. right material – wrong dumpster)
- Increasingly high diversion goals set by owners without corresponding resources
These challenges make waste management a logistical puzzle that requires planning, coordination, and accountability from the entire project team.
LEED v5 Waste Overview & Key Changes
With a new version of the LEED rating system, construction teams will now have to place even more emphasis on waste management. LEED v5 introduces changes to how projects manage and document construction and demolition waste diversion. These changes apply across each rating system.
Some of the most significant updates include:
- The credit is now called Construction and Demolition Waste Diversion
- The Construction and Demolition Waste Management Planning prerequisite has been removed and is no longer a required prerequisite
- Developing and implementing a waste management plan is now engrained in the credit requirements (Construction and Demolition Materials Management Plan)
- Projects must use a third-party certified recycling facility OR assume a default 35% diversion rate for commingled waste
- The USGBC is no longer accepting letters stating diversion rates from recycling facilities
- The focus has shifted from targeting a certain number of materials streams to a greater emphasis on total quantity of source-separated and/or salvaged material streams
This shift emphasizes verification, transparency, and planning, rather than relying on letters or estimates from recycling facilities.
Letโs dig deeper.
The updated credit requirements aim to streamline the process for project teams. By combining the waste management plan prerequisite with the actual waste management credit, teams can now address all the necessary elements within a single credit page, enhancing efficiency and reducing confusion. The more impactful changes are around the third party verified recycling facilities and default 35% diversion rate.
Currently, the market faces a limited availability of third-party verified recycling facilities, primarily due to the extensive certification process and associated costs. Even when facilities overcome these challenges and become certified, maintaining and/or producing high diversion rates (above 60-70%) remains a difficult task. Not to mention the regional difficulties with lack of local third party verified facilities near jobsites.
The default 35% diversion rate for commingled materials may seem easier in terms of workload, as teams no longer have to track down individual facility letters. Nonetheless, the industry does not consider a 35% diversion rate a high recycling rate. Project teams will still need to prioritize source-separation, focusing on the heaviest recyclable materials.
This is the perfect segway for the additional changes to the LEED requirements, being the greater focus on source-separate and/or salvaged materials at a certain percentage, rather than total number of streams.
In previous LEED versions, many project teams could take the approach of source-separating small quantities of waste just to reach the multiple waste stream goal. Now teams not only need to prioritize source-separating materials, but quantify source-separated materials as a percentage of the total waste on the project to comply.
With all of this in mind, let’s discuss the exact credit requirements under LEED v5 Construction and Demolition Waste Diversion.
LEED v5 BD+C Waste Requirements
Projects pursuing BD+C certification can choose between two diversion thresholds including two thresholds for source-seaparted and/or salvaged materials.
- Projects must divert at least 50-75% (by weight or volume) from landfills excluding Alternative Daily Cover (ADC) to get 1-2 points.
- Project teams must salvage or source-separate at least 10-25% of those materials as single material streams.
Best Pathway to Get Points:
Discuss waste management in the preconstruction phase. Establish local vendors that will take individual source-separated materials streams (metal, concrete, gypsum board, wood, etc.). If demolition is in scope, prioritize recycling demo materials with the heaviest weight and recyclability.
Aim to use a third-party certified recycling facility. You can identify these facilities through the Recycling Certification Institute (RCI) or through Green Badgerโs Waste Facility Map. Otherwise, the default commingled percentage is 35% for all commingled waste.
Refer to Green Badgerโs LEED v5 Waste Management Cheat Sheet for additional guidance on BD+C requirements.
LEED v5 ID+C Waste Requirements
Interior projects have multiple pathways to meet the credit.
The credit requirements remain the same for third party certified recycling facilities. Projects must utilize a third-party certified recycling facility or assume a 35% diversion rate for commingled materials.
Check out Green Badger’s LEED v5 Waste Management Cheat Sheet for additional guidance on ID+C requirements.
LEED v5 BD+C: Core & Shell Only
For Core & Shell projects, the Construction and Demolition Materials Management Plan must be included in the tenant guidelines, ensuring future tenants follow the buildingโs waste diversion strategy.
Best Practices for Waste Management Onsite
Now that we know the requirements, it is important to discuss best practices to achieve the goals of the project. Successfully achieving LEED waste diversion goals requires planning well before construction begins.
Some of the most effective strategies include:
- Waste management planning in the preconstruction phase
- Start developing the Construction and Demolition Materials Management Plan
- Get started with Green Badgerโs template plan[1]
- Begin identifying anticipated waste streams onsite and researching local recycling facilities (both commingled and single-stream recyclers)
- Prioritize Onsite Separation & Single Stream Opportunities
- Source-separated materials often achieve higher recycling rates and better reporting accuracy, plus itโs a requirement
- Materials like metal, cardboard, concrete, and gypsum are strong candidates for single-material recycling
- Identify single stream waste recyclers that serve your nearby project
- Develop a schedule to capture your top material streams for recycling when specific scopes are performing work onsite (i.e. when your drywall sub is onsite have a gypsum board dumpster onsite)
- Vet Haulers and Recycling Facilities for Commingled Waste
- Find a local facility that is third party certified by the Recycling Certification Institute (RCI) to meet LEED v5 verification requirements
- If a third party facility is not available nearby, take an estimate approach of the total waste produced on the project and apply the default 35% diversion rate to determine the projects anticipated diversion rate
- Train your Subcontractors & Label your Dumpsters
- Ensure your dumpsters have labels that are bold so all team members know what materials go in each dumpster
- Host a kick-off meeting with your subcontractors to review the waste management goals and ensure teams understand the importance of placing materials in the correct dumpsters to streamline material management
Finally, create a waste map or flow chart to identify waste streams that will be generated, how those streams will be sorted, where dumpsters/bins will be located onsite, and where materials will be transported across the jobsite.
Post this map throughout the jobsite so all teams know where individual dumpsters are located.
For projects dealing with a zero lot line or lack of space, the approach of phasing material streams could serve as the most useful practice. Using smaller dumpsters (regular trash can, tote, laundry hamper) could also provide teams dealing with limited space the opportunity to achieve the requirement of diverting a specific percentage of individual waste streams to meet the LEED goals.
Key Takeaways
Navigating LEED v5 waste requirements is more complex than previous versions, but manageable with the right approach. Here are the most important points to keep in mind:
- The prerequisite is gone, but the bar is higher. The Construction and Demolition Waste Management Planning prerequisite has been eliminated, but waste planning is now baked directly into the credit โ meaning teams still need a formal Construction and Demolition Materials Management Plan.
- Third-party certified facilities are the gold standard. LEED v5 no longer accepts facility letters stating diversion rates. Projects must use a third-party certified recycling facility (verifiable through RCI) or accept a default 35% diversion rate for commingled waste โ which makes earning points harder.
- Source-separation is no longer optional. Unlike previous versions where teams could source-separate minimal quantities to hit a stream count, LEED v5 requires source-separated and/or salvaged materials to represent a meaningful percentage of total project waste.
- Planning early is everything. Identifying local haulers, scheduling dumpster rotations around subcontractor scopes, and establishing a waste map before construction begins are the most effective options a project team has.
- Space constraints require creative solutions. For tight jobsites, phased waste collection and smaller containers can make multi-stream separation feasible without sacrificing diversion goals.
Project teams that invest in early planning, prioritize source-separation, and partner with certified recycling facilities will be far better positioned to hit their diversion thresholds and earn points. Waste management has always required coordination across the entire project team. Under LEED v5, that collaboration isn’t just best practice, it’s a necessity.
Conclusion
LEED v5 raises the stakes for construction waste management. With over 600 million tons of C&D waste generated annually in the U.S., the industry has a meaningful role to play in reducing landfill dependency and advancing a circular economy in the built environment.
The updated credit structure pushes project teams toward greater accountability, verified data, and genuine diversion rather than paper compliance. While the shift to third-party certified facilities and percentage-based source-separation thresholds introduces new logistical challenges, it also creates an opportunity for teams that plan ahead to differentiate themselves.
Success under LEED v5 won’t happen by accident. It requires early coordination, subcontractor buy-in, smart vendor selection, and consistent tracking throughout construction. Teams that treat waste management as a core project deliverable rather than an afterthought will be best positioned to earn points, reduce environmental impact, and set a new standard for sustainable construction practices.
