Waste diversion is often top of mind with executives, but most conversations start in the wrong place. When you send waste to a landfill, you’re paying to buy real estate you’ll never use again; that’s usually the moment waste diversion becomes a real agenda item, not just a talking point.

The discussion at many companies begins with questions like:

• How do we reduce landfill volumes?
• Are there opportunities to improve waste diversion rates? Recycle more or even make money?

While those are reasonable questions, they’re just not the first ones to ask. Before a waste stream can be recycled, recovered, repurposed, or optimized, it has to be understood.

• What exactly is it?
• Where is it generated?
• How is it currently managed?

Without those answers, diversion becomes guesswork. 

The Assumption Gap

Many facilities understand the streams that get the most attention. But there’s a real difference between a compliant waste program and one that actively works for you.

A compliance-oriented program documents the streams that have been reviewed, carefully manages the regulated ones, and keeps the paperwork current. That’s necessary, but it leaves a second category largely untouched — streams handled informally, routed to disposal by default, or simply never evaluated. Not because nobody had time to look but because nobody looking at them knew there was anything to find.

That second category is almost always larger than the EHS team realizes.

It is where most waste diversion opportunities are found.

Consider what a typical compliance-first inventory misses:

• Process residuals not currently routed to any diversion pathway, even though characterization could qualify them for one.
• Streams where generation rates have changed but disposal costs haven’t been revisited since the program was last built.
• Packaging and secondary materials: high-volume streams like corrugate, film wrap, foam, and mixed plastics that go to disposal because no one has evaluated whether they qualify for recycling or commodity recovery.
• Maintenance waste streams with no formal profile: spent lubricants, used filters, and cleaning residuals managed by habit rather than by documented characterization.
• Materials that could be remediated, recycled, or reclaimed:  contaminated, off-spec product, recoverable metals, solvents or plastics sent straight to disposal because no one has evaluated whether processing could recover value or reduce the volume requiring disposal.

None of these require a crisis to surface. They require a different set of eyes.

To most people standing in front of it, a stream like this just looks like waste. It’s been handled the same way for years, and nothing about it signals there might be another option. That’s what happens when the people managing a stream day-to-day have never had a reason or the time to ask what else it could become.

An experienced eye looks at the same stream and sees something different. That gap between what a stream looks like and what it is is where most opportunities for diversion hide.

Waste Diversion Starts with Visibility

Organizations often think of diversion as a destination when, in reality, it’s an outcome.

The process begins with visibility. When a facility develops a complete understanding of its waste streams, three things become possible.

1. Recovery opportunities become visible: Materials that have historically been sent to disposal may qualify for commodity recycling, vendor take-back programs, material recovery programs, or waste-to-energy solutions. These opportunities cannot be evaluated until the material itself is understood.
2. Disposal decisions become more strategic: Many disposal pathways were chosen years ago and never revisited, even as operations, volumes, and markets changed. Characterization alone doesn’t create diversion. Someone also has to know which recyclers, reclaimers, processors, and recovery outlets can take the material. A stream may be technically recyclable and still have no practical outlet in your region. One that’s always gone to disposal may suddenly have value because markets shifted. This is where many diversion efforts stall. Facilities understand the waste stream but never connect that understanding to the organizations capable of recovering, reclaiming, or repurposing it.
3. Sustainability claims become defensible: ESG reporting and diversion goals depend on accurate data. A diversion percentage only has value when the underlying waste streams have been identified, quantified, and tracked. Confidence comes from knowing where the numbers came from.

Visibility identifies the opportunity. Market knowledge determines whether and how  it can be captured.

What ‘Knowing Your Waste’ Can Mean

Knowing your waste is not the same as knowing your waste program.

A waste program tells you how the streams you’ve already documented are being managed.

Knowing your waste means understanding the complete picture: what your facility generates, in what quantity, with what regulatory status, and what options exist for disposal, recovery, remediation, reclamation, or diversion.

The distinction matters because diversion decisions are downstream of characterization. Before you can evaluate whether a stream qualifies for commodity recovery, a vendor take-back program, or a recycling pathway, you need to know:

• What it is. Physical and chemical properties — not just a container label or a standing pickup arrangement.
• Where it comes from. Which process generates it, under what conditions, and at what rate.
• Whether the characterization is current. A profile built on process knowledge from two or three years ago may not reflect what’s going into the container today, especially after raw material substitutions, equipment changes, or vendor shifts.
• What options exist. Disposal is the default when no one has evaluated the alternatives. Characterization opens the door to evaluating them.

Five Signs Your Inventory May Have Gaps

You don’t need a facility-wide audit to know if something is worth a closer look. These five situations are reliable warning signs that it may be worth bringing in another set of eyes with recycling, reclamation, and diversion expertise.

1. It’s been a while since anyone reviewed your waste streams. If you can’t remember the last time someone walked the full operation and evaluated every waste stream, the inventory could be out of date. Processes change, materials change, and equipment changes, but profiles built years ago rarely get revisited unless something forces the issue.
2. Disposal costs have increased faster than production. If production is up 5% but disposal costs are up 20%, the gap typically reflects streams that have grown or changed without anyone evaluating them. Either new streams were added to disposal by default, or existing profiles are directing material toward more expensive disposal pathways than necessary.
3. A significant portion of your diversion reporting is estimate-based. If sustainability reporting or ESG disclosures rely on estimates rather than documented diversion records, the characterization baseline likely has gaps. Defensible reporting requires a foundation that was documented, not reconstructed after the fact.
4. Waste streams are being managed by standing arrangement rather than current documentation. When vendors are managing streams the same way they were three years the arrangement may reflect what was convenient at setup, not what’s optimal today.
5. No one on staff specializes in recycling, reclamation, or diversion markets. Most EHS and operations teams are excellent at compliance. Few have a standing relationship with the buyers, processors, and reclamation outlets that turn a given stream into revenue instead of a disposal cost. Without that network, even a well-documented stream tends to stay on the same disposal path because no one is positioned to know it could go anywhere else.

Any one of these conditions is worth paying attention to. Together, they signal that the inventory is doing compliance work but not yet performing as a decision-making tool. 

The Most Valuable Question

When facilities begin evaluating diversion opportunities, there is one question that consistently produces useful conversations:

“What are we currently paying to dispose of that might have another destination?”

Sometimes the answer is nothing. Often, it isn’t.

One of the biggest misconceptions in waste diversion is that every stream should be recycled. That isn’t the goal. Some materials belong in recycling programs, some in reclamation programs, some in waste-to-energy programs, and some belong in disposal. The objective isn’t to force diversion. It’s to understand the stream well enough to choose the destination that actually fits, driven by data instead of assumptions no one has tested.

Mid-Year, A Natural Inflection Point

July marks the midpoint of the year, and that matters for diversion. Six months of generation data is enough to see real patterns — which streams are growing, which disposal costs are climbing faster than they should, which materials have accumulated long enough to justify a recovery conversation. Markets shift as well: a stream with no viable outlet in January may have one now, or the reverse. Waiting until December means running the second half of the year on whatever default arrangement, and whatever market conditions, happened to be in place when the program was last reviewed.

The organizations that consistently control costs, improve diversion outcomes, and maintain compliance are rarely the ones reacting to problems. They’re the ones who used a moment like this one to look at what the year’s data was already telling them.

The Foundation Comes First

Every successful diversion strategy begins with the same starting point: a clear understanding of what the facility is generating today.

Before you can improve a waste stream, you have to know it exists. Before you can recover value, you have to know where it’s hiding. Before you can make better decisions, you need visibility into what’s actually moving through your operation.

The strongest waste diversion programs don’t start with diversion goals.

They start with understanding.

Everything else is built from there.

At TBK Environmental, we help facilities gain visibility into their waste streams, identify opportunities for improvement, and build practical strategies that support compliance, operational performance, and long-term sustainability. Because the best diversion strategy isn’t the one that sounds good, it’s the one built on facts.

Frequently Asked Questions

What is waste diversion?

Waste diversion is the practice of redirecting material away from landfill disposal toward recycling, reclamation, reuse, or waste-to-energy pathways. Effective waste diversion depends on first understanding what a waste stream actually is, not just where it currently goes.

Why doesn’t compliance alone lead to good waste diversion outcomes?

Compliance programs are built to manage regulated streams correctly, not to identify diversion opportunities. Many facilities have a second, unevaluated category of waste, such as packaging, maintenance residuals, and off-spec materials, that is compliant by default but has never been assessed for recovery or recycling value.

How do I know if my facility is missing waste diversion opportunities?

Common signs include disposal costs rising faster than production, diversion reporting that relies on estimates rather than documented data, and waste streams still being managed under vendor arrangements that haven’t been reviewed in years. This TBK Environmental article covers these five specific signs in detail.

What’s the difference between waste characterization and waste diversion?

Waste characterization identifies what a material is, where it comes from, and its regulatory status. Waste diversion decisions, whether a stream can be recycled, reclaimed, or recovered, are downstream of that characterization. You cannot make informed diversion decisions without an accurate, current characterization first.

When is the best time to review a waste diversion program?

Mid-year is a natural checkpoint: there’s enough generation data from the first half of the year to spot real trends, and enough runway left to act on findings before year-end planning begins. Programs reviewed only annually often run for months on outdated assumptions.
