If you cannot measure your waste, you cannot improve it.

A waste diversion audit is the foundation of any successful recycling program. It gives you a clear picture of what is being thrown away, what could be diverted, and where your system is breaking down.

For facilities, campuses, municipalities, and businesses, this is not just a sustainability exercise. It is a way to reduce cost, improve ESG reporting, and create a system that actually works in the real world.

This guide walks through exactly how to conduct a waste audit, where to get your data, and how to turn that information into a strategy that improves diversion.

A waste diversion audit is the process of analyzing your waste streams to determine:

  • How much waste you generate
  • What percentage is diverted from landfill
  • What materials are being incorrectly disposed of
  • Where contamination is occurring

The goal is simple: identify opportunities to increase recycling and reduce landfill waste.

Your waste hauler is one of your most important data sources, but most organizations underutilize this information.

What to Request From Your Hauler

Start by asking for the following:

  • Monthly or quarterly waste reports
  • Total landfill tonnage
  • Recycling tonnage by material (if available)
  • Compost or organics tonnage
  • Pickup frequency and container sizes
  • Contamination reports or rejected loads

If your hauler cannot provide detailed reporting, that is a signal in itself. You may need to supplement with internal tracking or explore partners who can provide better data transparency.

Key Metrics to Calculate

Once you have the data, calculate:

  • Total waste generated
  • Total diverted waste (recycling + compost)
  • Diversion rate = (diverted waste / total waste) × 100

A typical diversion rate varies widely, but many organizations fall between 20 and 40 percent without optimization.

Data tells you what is happening. A physical audit tells you why.

How to Run a Waste Sort

  1. Choose a representative area or building
  2. Collect waste from all streams over a set period (typically one day)
  3. Sort waste into categories:
    • Landfill
    • Paper
    • Containers (bottles and cans)
    • Organics
    • Specialty waste (e-waste, film plastic, etc.)
  4. Weigh each category
  5. Document contamination

Incorrectly recycled materials

What You Are Looking For

  • Recyclables in landfill bins
  • Contamination in recycling bins
  • Volume of compostable material being lost
  • Mismatch between bin types and actual waste generated

This step is where most insights come from.

Before making changes, understand what exists today.

Evaluate Your Bin System

Walk your facility and assess:

  • Are there enough bins?
  • Are bins located where waste is generated?
  • Are landfill and recycling paired together?
  • Are streams consistent across the building?

Many facilities rely on inconsistent or outdated bins, which leads to poor participation.

Bins with no signage

Upgrading to standardized systems like centralized recycling stations can significantly improve performance.

Assess Bin Types and Functionality

Look at:

  • Open tops vs restrictive lids
  • Indoor vs outdoor durability
  • Capacity vs actual waste volume

Three stream trash, recycling, and compost system

Using clearly defined containers such as multi-stream recycling bins helps reduce confusion and contamination.

At this point, patterns should emerge.

Common Audit Findings

  • High percentage of recyclables in landfill
  • Contaminated recycling streams
  • Lack of composting in food areas
  • Poor bin placement in high-traffic zones
  • Overcomplicated systems that users ignore

One of the most common issues is that bins do not match behavior. For example, food areas without compost options almost always drive landfill waste.

Adding targeted solutions like compost bins for food waste can dramatically increase diversion.

Now turn insights into action.

Simplify Your Streams

Do not overcomplicate your system. Most facilities perform best with:

  • Landfill
  • Recycling
  • Compost (in select areas)

Clarity always beats complexity.

Standardize Your Infrastructure

Use consistent bins, colors, and signage across all areas.

Products like office recycling bins and desk side recycling bins help create uniform systems that are easier to maintain.

Improve the Moment of Decision

The most important moment is when someone throws something away.

Improve this by:

  • Clear labeling
  • Color coding
  • Restrictive openings

Solutions such as recycling bins with lids help guide correct disposal.

Align With Your Hauler

Make sure your system matches what your hauler actually accepts.

There is no value in collecting materials that cannot be processed downstream.

Even the best system will fail without user participation.

Focus Areas

  • Employee education
  • Clear signage
  • Simple instructions
  • Consistent messaging

Custom recycling signage and graphics can reinforce correct behavior at the point of disposal.

A waste audit is not a one-time event.

Ongoing Tracking

Monitor:

  • Diversion rate
  • Contamination rate
  • Waste per occupant
  • Hauling costs

Use tools like the Recycling Toolkit to standardize tracking and reporting.

Continuous Improvement

Revisit your audit quarterly or annually to:

  • Identify new opportunities
  • Adjust bin placement
  • Optimize service schedules
  • Improve signage and communication

Overcomplicating the System

Too many streams lead to confusion and contamination.

Ignoring Bin Placement

If a bin is not where waste is generated, it will not be used correctly.

Mismatched Infrastructure

Using the wrong bins for the environment reduces effectiveness.

Explore solutions like commercial recycling bins designed for specific use cases.

Lack of Data

Without tracking, there is no accountability or improvement.

A successful waste diversion program is:

  • Easy to understand
  • Consistent across all areas
  • Aligned with hauler capabilities
  • Measurable and continuously improving

Most importantly, it reflects how people actually behave, not how we hope they behave.

A waste diversion audit is the most powerful tool you have to improve your sustainability program.

It turns assumptions into data
It reveals where systems fail
It provides a clear path to improvement

With the right data, infrastructure, and strategy, organizations can significantly reduce landfill waste, improve ESG performance, and create systems that work every day.

At least once per year, with quarterly reviews for high-volume facilities.


Many organizations target 50 percent or higher, with best-in-class programs exceeding 75 percent.

No, but their data is critical. Internal audits provide deeper insights into behavior and contamination.

Simplify streams, improve bin placement, and upgrade signage and containers.
