Beneficial Use Determinations Explained: When You Need One, When You Don't, and How the NJDEP Process Actually Works
If you've been told your material might need a "BUD" before you can reuse it, you're probably not alone in wondering what that even means. It's a term that gets thrown around in New Jersey environmental circles, but most people who hear it for the first time have no idea whether it applies to them, how long it takes, or whether there's a simpler path they're missing entirely.
In this article, we'll break down what a Beneficial Use Determination actually is, how the New Jersey Department of Environmental Protection (NJDEP) reviews and approves one, what materials typically need one, and how it compares to the recycling approvals, exemptions, and RD&D approvals most facilities end up using instead. If you're trying to figure out where your material fits, reach out to RMA and we'll help you sort it out.

TL;DR
A Beneficial Use Determination (BUD) is an NJDEP approval that lets you use a specific material, for one specific purpose, instead of managing it as solid waste. It requires testing data, an engineering justification, and review by NJDEP's Bureau of Recycling and Hazardous Waste Management, and it results in a Certificate of Authority to Operate tied to that exact material, use, and site. Most facilities don't actually need one. A BUD only makes sense when a material genuinely doesn't fit into New Jersey's existing Class A, B, C, or D recycling approvals, its recycling exemptions, or an RD&D approval for materials still being tested at limited scale.
What Is a BUD in New Jersey?
A Beneficial Use Determination, or BUD, is a written approval issued by NJDEP that allows a facility to use a specific material, for a specific purpose, instead of managing that material as solid waste. In plain terms, it's NJDEP saying "yes, this particular material can be used this particular way instead of throwing it away".
Under New Jersey's solid waste rules, almost anything that isn't a raw material or a finished product defaults to being classified as waste, even if it's technically perfectly usable in some application. A BUD is the mechanism that lets you step outside that default classification for a narrow, specific circumstance.
A BUD isn't a general recycling license and it isn't transferable. It applies to one material, used one way, at one location. If any of those three things change, the BUD doesn't cover it anymore.
How Does the New Jersey BUD Application Process Work?
Getting a BUD starts with an application submitted to NJDEP's Bureau of Recycling and Hazardous Waste Management. Among lots of other standard information, that application needs to include two core pieces.
The first is material characterization. This means real testing data that identifies exactly what the material is, what it contains, and how it behaves. NJDEP isn't going to take your word for it. They want lab results that back up every claim about the material's composition.
The second piece is an engineering justification. This is where you explain, in technical terms, why the specific use you're proposing is safe for that material, at that concentration, in that application. A material that's safe to use as structural fill isn't automatically safe to use as a soil amendment, and NJDEP wants to see the reasoning connected to the actual proposed use, not a generic safety argument.
Once NJDEP has the application, their reviewers evaluate the technical merits. It's common for them to come back with follow-up questions, request additional testing, or push back on the proposed use if they're not convinced it's been adequately justified. This isn't a rubber-stamp process. If NJDEP is satisfied with the application, they issue a written decision called a Certificate of Authority to Operate. That certificate is the actual BUD, and it spells out exactly what material is covered, what it can be used for, and where.
Two things are worth remembering here. A BUD isn't a permit you renew annually the way you might with a stormwater permit or an air permit. And it's not a blanket approval. If you want to use a different material, use the same material a different way, or use it at a different site, you need a new BUD or a modification, not an extension of the one you already have.
Who Actually Needs a BUD in New Jersey?
You need a BUD when your material genuinely doesn't fit into any of New Jersey's existing recycling categories, and the only legal alternative to a BUD is treating that material as solid waste and disposing of it.
That's a rarer situation than you might think. New Jersey already has an established framework for reusing most common materials through Class A, B, C, and D recycling approvals, a separate set of recycling exemptions that cover specific materials and situations without requiring a full approval at all, and RD&D approvals for materials or processes that are still being tested. Between those frameworks, the vast majority of reusable materials already have a defined path.
A BUD exists for the materials that fall through the cracks of that system. Maybe it's an industrial byproduct that doesn't match any existing recyclable material class. Maybe it's a use case nobody had anticipated when the existing categories were written. In those situations, a BUD is the tool that lets NJDEP evaluate something on its own merits rather than trying to force it into a category that doesn't quite fit.
If your material does fit an existing category, going after a BUD instead is usually the wrong move, not because the existing path is quick or easy (a Class A, B, C, or D approval can take real time and money on its own) but because it's the route NJDEP actually requires. Pursuing a BUD on top of that just adds an extra, unnecessary layer of testing, engineering justification, and review to a process you'd still have to complete anyway.
BUD vs. NJ Recycling Approvals, Exemptions, and RD&D: What's the Difference?
It helps to think of New Jersey's system for reusing materials as four separate lanes, each built for a different situation.
Class A, B, C, and D recycling approvals are the standard path for most reusable materials in New Jersey. These classes cover categories of materials NJDEP has already defined and regulated, and getting approved means demonstrating your facility and process meet the requirements for that class.
Recycling exemptions cover specific, narrowly defined materials and situations where NJDEP has decided a full approval isn't necessary. If your situation matches an exemption exactly, it's usually the fastest and least expensive route available.
The fourth lane is an RD&D approval, short for Research, Development, and Demonstration. This is the path for materials or processes that are still being proven out, where you want to test a reuse concept at a limited, temporary scale. It's less about qualifying a material for long-term reuse and more about getting NJDEP's sign-off to run a controlled trial first.
A BUD is different from all three. It exists for materials and uses that don't fit anywhere in the class system, don't match any existing exemption, and aren't just a matter of needing to test the concept first. An approval, exemption, or RD&D is a defined framework NJDEP has already built out, so they know exactly what they're evaluating and against what standard. A BUD asks NJDEP to evaluate something from scratch, which is why it tends to involve more back-and-forth even when the underlying material isn't especially complicated.
An exemption (when your situation truly qualifies) is genuinely the fastest, lowest-cost option of the four. A Class A, B, C, or D approval usually isn't fast or cheap, but it's the legally correct path once your material and use fit the definition, and NJDEP isn't going to let you skip it in favor of a BUD just because a BUD sounds more direct.
In practice, nine times out of ten, a facility that thinks they need a BUD actually needs a regular recycling approval, qualifies for an exemption, or should be looking at RD&D first.
What Materials Typically Require a BUD in New Jersey?
BUDs tend to show up around industrial byproducts and unconventional reuse proposals rather than common construction or demolition materials. Materials like certain foundry byproducts, specialized manufacturing residuals, or novel aggregate substitutes are the kinds of things that often need a BUD, simply because nobody has defined a recycling class or exemption specifically for them.
The proposed use matters just as much as the material itself. The same byproduct might be a straightforward fit under an existing class if it's being used one way, and might require a full BUD if someone wants to use it a different way that NJDEP hasn't evaluated before. This is part of why a BUD application has to be so specific. NJDEP isn't approving the material in the abstract. They're approving that material for that use.
How Long Does It Take to Get a BUD in New Jersey?
There's no fixed timeline for a BUD, and that's one of the biggest differences between a BUD and a standard recycling approval. Because NJDEP is evaluating something they haven't pre-approved a framework for, the review can involve multiple rounds of questions, requests for additional testing, or back-and-forth on the engineering justification before they're satisfied.
A straightforward BUD for a well-characterized material with an obvious safety case can move relatively quickly. A BUD involving a material with limited existing data, or a use case NJDEP hasn't seen before, can take considerably longer. If timing is a factor in your decision, that's another reason to confirm you actually need a BUD before committing to the process. Confirming that isn't a guarantee of a faster outcome. It just makes sure you're not spending time and money on a BUD when your material was already required to go through a Class A, B, C, or D approval, or better yet, genuinely did qualify for a fast, low-cost exemption.
Common Mistakes in New Jersey BUD Applications
By far the biggest mistake we see is treating a BUD as "a way around" a Class A, B, C, or D approval. People hear that a full recycling approval can be time-intensive, expensive, and complicated, and they assume a BUD is the shortcut. It almost never works that way. NJDEP determines which path applies based on the material and the use, not based on which route you'd rather take. If your material fits the definition of a Class A, B, C, or D recyclable, NJDEP is going to require you to go through that approval regardless of how you feel about the timeline or the cost. Showing up with a BUD application for a material that clearly belongs in the class system doesn't speed anything up. It just adds a rejected or redirected application to the front of a process you were going to have to complete anyway.
Another common mistake is submitting testing data that characterizes the material but doesn't connect clearly to the proposed use. NJDEP wants to see the engineering logic laid out explicitly. A lab report by itself doesn't make that case.
And a third mistake is treating a BUD like a permanent, transferable approval. Because it's tied to one material, one use, and one site, any change to those variables (a new supplier, a new application, a new facility) means the existing BUD doesn't carry over automatically.
How RMA Helps With BUD Applications in New Jersey
Nine times out of ten, if you reach out to us about a BUD, what you actually need is a standard recycling approval. We've helped more facilities get Class A, B, C, and D recycling approvals in New Jersey than just about anyone else. If that's where your material falls, we'll help you get it done right.
If it turns out an RD&D approval is the better fit, we're happy to facilitate that process too, though it's a less common situation than a standard approval. If it turns out you actually qualify for an exemption, we'll tell you that honestly and point you in the right direction. Exemptions are usually simple enough that you can handle them yourself, and we'll be upfront about that rather than talk you into hiring us for something you don't need.
And if it turns out you genuinely do need a BUD, which is probably the least likely of these four situations, we can help with that too. We'll manage the application package and the back-and-forth with NJDEP through the review process so you know it's being handled the right way.
Regardless of which of these four paths your material falls under, we can help. Reach out to RMA by phone, email, or the form on our website, and we'll help you figure out where you stand.
