LEED Construction & Demolition Waste Management Plan

For commercial builders and project managers, the LEED Construction & Demolition Waste Management Plan (C&D WMP) serves as a tool for balancing eco-friendly waste practices with construction needs. This guide explains what goes into a LEED C&D WMP, effective strategies, and how Fuzion can help streamline the process.

Understanding LEED and the Role of C&D Waste Management

LEED Overview

Leadership in Energy and Environmental Design (LEED) is a worldwide certification developed by the US Green Building Council (USGBC). It sets detailed standards for creating sustainable buildings through design, construction, and operation. Projects gain points in various areas and can reach one of four levels: Certified, Silver, Gold, or Platinum.

Within LEED, the Materials and Resources (MR) credit category emphasizes waste reduction, sustainable sourcing, and building life-cycle impact reduction. Credits MRc2.1 and MRc2.2 specifically target construction and demolition (C&D) waste management​​.

Purpose of C&D Waste Management Credits

These credits emphasize the importance of reducing the environmental impact of construction waste by diverting debris from landfills. A successful LEED C&D Waste Management Plan achieves the following:

• Diverts Construction & Demolition Debris:
  Diverts a minimum of 50% of non-hazardous C&D debris (v4.1) or 75% (v4) by promoting recycling and reuse practices​.
• Promotes Material Reuse and Recycling:
  Encourages the reuse and recycling of materials to redirect them from disposal, thereby reducing demand for virgin materials and minimizing the project's carbon footprint​​.
• Establishes Diversion Goals:
  Sets clear goals and defines five targeted materials to ensure valuable resources are repurposed, ultimately supporting circular economy principles​​. These targeted materials typically include concrete, metals, wood, masonry, and cardboard​​.

By providing a broader context for sustainable waste management, these credits guide construction projects in reducing their environmental impact and promote the responsible handling of valuable resources.

Changes in LEED v4.1

LEED v4.1 simplifies Construction Waste Management credits by reducing material stream targets and excluding demolition waste from the total calculation, making it easier for project teams to achieve higher diversion rates and streamline certification.

Simplified Material Stream Requirements

Reduced stream targets: 50% reduction using commingled recycling plus one stream, 75% reduction plus two streams.

Option 2 Improvements

Demolition waste exclusion and new waste thresholds: 7.5 lbs/sf (new construction), 2.5 lbs/sf (Core and Shell projects).

Enhanced Reporting Accuracy

Commingled facilities must provide project-specific diversion rates; visual inspection is no longer sufficient.

These changes make it more feasible for project teams to achieve higher diversion rates, improve waste management strategies, and earn valuable LEED credits.

LEED Construction & Demolition Waste Management Plan Requirements

Waste Diversion Goals

A LEED C&D WMP sets specific waste diversion goals to ensure compliance with MR credits:

• LEED v4.1: Divert a minimum of 50% of C&D debris by identifying and targeting three material streams.
• LEED v4: Divert at least 75% of C&D debris by identifying and targeting five material streams​​.

Key Plan Components

Identification of Waste Sources

Recognizing the primary sources of waste, including concrete, scrap metal, cardboard, timber, and more​​.

Exclusion of Non-Qualifying Materials

Excavated soil and land-clearing debris cannot count toward diversion credits​​.

Waste Stream Calculation

Different recycling protocols (e.g., commingled vs. separate bin) and their respective diversion requirements​​.

Recycling Protocols

Outline the method of recycling (commingled or separate bins) and set specific diversion rate targets for each material​​.

Tracking and Reporting

Prepare detailed documentation of each waste stream's diversion and disposal rates. Reporting must be consistent with LEED credit requirements​.

Example Materials and Estimated Diversion Rates

Targeted materials typically include concrete, metals, wood, masonry, and cardboard. Diversion rates vary per project, with concrete reaching up to 40%, metals up to 15%, and other materials like gypsum board and cardboard varying accordingly.

Strategies for Sustainable Waste Management

Advanced Planning and Waste Reduction Strategies

Advanced planning is crucial for effective waste management. By incorporating waste reduction strategies during the design and construction planning phases, projects can significantly reduce waste and improve resource efficiency. Here are some practical strategies:

• Comprehensive Waste Management Plan (MRp2):
  Develop a plan under MRp2 that identifies at least five materials for diversion and outlines specific means for achieving this. For example, the XYZ Tower project implemented a detailed plan that targeted concrete, metals, wood, masonry, and cardboard for diversion, achieving a 75% diversion rate​.
• Design for Waste Reduction:
• Use building information modeling (BIM) to optimize material usage and reduce errors during construction.
• Specify materials with minimal packaging and recycled content to reduce overall waste​​.
• Early Contractor Involvement:
  Involving contractors early during the design phase can help identify potential waste reduction opportunities, leading to more efficient waste separation and recycling strategies during construction​​.

By implementing advanced planning and waste reduction strategies, construction projects can significantly reduce their environmental impact, improve efficiency, and achieve higher LEED credits.

Phased Waste Separation

Phased waste separation is an effective approach that enables efficient recycling of construction and demolition waste at different stages of a project. By strategically placing dumpsters based on the project's progression, project managers can maximize waste diversion rates.

Early Phase:
During the site work and foundation stages, dedicated concrete dumpsters are placed to handle large amounts of concrete waste. These dumpsters ensure that valuable concrete can be separated early on, preventing contamination and promoting efficient recycling.

Vertical Construction:
As the project advances to the vertical construction phase, commingled recycling dumpsters become essential for managing the majority of mixed waste generated, including wood, drywall, and other common construction materials. These dumpsters are supplemented by additional recycling bins specifically for metals, allowing for the separation and recycling of steel and other metallic debris.

Final Phase:
In the final phase, additional dumpsters are introduced for short-term materials like wood pallets and cardboard. By providing specific containers for these materials, project managers can effectively separate and divert these valuable resources from landfill disposal.

This phased approach allows construction projects to minimize their environmental impact while ensuring compliance with LEED waste management credits.

Collaboration with Waste Haulers

Waste haulers play a crucial role in effective waste management. Key considerations include:

• Process Understanding: Ensure haulers provide accurate diversion rates and transparent documentation​​.
• Certification: Haulers should be RCI (Recycling Certification Institute) certified or have state-regulated diversion reports​​.
• Project-Specific Reporting: Obtain reports detailing the sorting and tracking of each material​​.

Optimizing Supply Chain for Sustainable Waste Management

Effective supply chain management involves:

• Supplier Contracts: Oblige suppliers to meet waste-recovery targets and minimize packaging waste​​.
• Excess Material Returns: Choose suppliers who accept returns or buy back excess materials for reuse or recycling​​.

Best Practices for LEED MRc5 Compliance

Achieving compliance with LEED Materials & Resources Credit 5 (MRc5) requires a multifaceted approach, focusing on the sustainable procurement and use of building materials throughout the construction process.

• Dumpster Strategies: Phase in dumpsters based on project timeline; use roll-off containers where space is limited.
• Diversion Tracking: Track demolition waste separately and divert at least 75%; ensure accurate calculation of waste streams​​.
• Reporting Accuracy: Commingled facilities must provide project-specific diversion rates; visual inspection isn't acceptable​​.
