Foam Scrap Buyers Explained: Who Pays for Logs, Who Wants Bricks, and Who Only Takes Pellets
Foam scrap only has value in the form your buyer accepts. Densified foam is sold in three main formats: compressed logs, hot-melt bricks (also called ingots), and, further down the chain, recycled pellets. For a fabricator, the working choice is between logs and bricks; pellets belong to the reprocessing specialists who buy those logs and bricks as feedstock. Each format ships at a different density and sells to a different kind of buyer. Pick the format before you pick the machine, and the machine pays for itself. Pick it after, and you may own equipment that produces something your nearest buyer will not take.
This guide breaks down who buys each format, what they pay for, and how a foam fabricator or converter should decide.
What Are the Three Formats of Densified Foam Scrap?
Densified foam scrap comes in three commercial forms. Logs are produced by compression: mechanical pressure squeezes the air out of the foam without melting the material through. Bricks or ingots are produced by thermal densification: the foam is melted and extruded into dense blocks. Pellets are a later stage entirely: fully reprocessed resin, produced by specialists from the logs and bricks fabricators sell them.
The difference is not just cosmetic. It changes density, freight economics, and who will buy from you.
Logs (compressed): The polymer is compressed, not melted through. Our AC Series compactors compress PE foam scrap into a square log and heat the outer surface, forming a thin rigid shell that holds the log's shape while the core stays unmelted foam. Output reaches up to 30 lbs/ft³ bulk weight, and the logs feed directly into most grinders or shredders for recycling. That shell is what basic cold-press systems lack, which is why their logs tend to run less dense and need strapping to hold shape. Because the bulk of the polymer is never melted, the material stays closer to virgin condition, which matters to buyers who reprocess it themselves.
Bricks or ingots (hot-melt): Heat collapses the cell structure completely. The foam is melted through and extruded, which is how our AD Series auger densifiers work: EPS, EPP, and EPE go through a full melt process and flow out through a die into dense, uniform bricks at up to ~30 lb/ft³ bulk weight, loading up to 40,000 lb per 40-foot container. Fully melted material needs less secondary processing on the buyer's end, which is why some recyclers quote only on bricks.
Pellets: Uniform granules, typically 3 to 5 mm, produced on a pelletizing line with extrusion, filtration, and degassing. Pellets are direct feedstock for injection molding and extrusion. They command the highest price and the strictest quality specs.
One material note before the buyer breakdown: polyethylene foam (EPE and PE plank drops) and polystyrene foam (EPS) are different polymers with different buyer pools. A PE foam buyer will not take PS bricks in the same stream, and mixing the two kills the value of both.
Who Buys Compressed Foam Logs?
Foam logs sell to two buyer groups: reclaimers who pelletize the material at their own facility, and resin producers running buy-back or closed-loop programs. Both prefer compressed PE logs with an unmelted core because the intact polymer gives them full control over reprocessing. If your buyer is a pelletizer, logs are usually the format they ask for.
We saw this pattern directly at Foam Expo North America 2026. A California pelletizer of recycled materials told us they specifically want densified logs from fabricators, because they run the pelletizing themselves and pay for clean, consistent input. Resin producers such as Pregis operate closed-loop recycling programs for their LDPE foam products, and fabricators inside those programs ship densified scrap back into the loop. For PE plank drops and trim, this is the buyer pool our AC Series compactors were built to serve: the machine outputs the dense, unmelted PE foam logs these buyers count on.
Log buyers care about three things:
Polymer purity: PE logs with tape, labels, film laminate, or mixed PS content get downgraded or rejected.
Consistency: Uniform density from a properly set compactor, load after load.
Volume: Most buyers set minimum shipment quantities, so your output rate has to fill a trailer on a schedule they accept.
Who Wants Hot-Melt Bricks Instead?
Brick and ingot buyers are typically recyclers and exporters who value shipping density and reduced reprocessing. Fully melted material packs tight, holds its shape without strapping, and grinds straight into the buyer's process. Buyers located far from your plant, and buyers who grind ingots straight into their process, tend to prefer bricks.
There is a freight math behind this preference. A trailer of loose EPS weighs only a few hundred pounds. Densified, the same trailer can carry up to 40,000 lbs of material. When your buyer is 800 miles away, that difference decides whether the load is worth sending at all.
Bricks also tolerate more variety on the input side. Thermal densification handles EPS, EPP, and EPE, and copes better with colored or lightly printed foam than cold systems do. For a fabricator running mixed bead-foam scrap, bricks are often the only format a buyer will quote, and it is the exact job the AD Series densifier is sized for: one machine covering all three bead foams into a single brick output.
The trade-off: heat changes the polymer. Some reprocessors discount fully melted material against compressed logs for exactly this reason, while others pay a premium for the density. This is buyer-specific, which is the point of this article.
Why Do Some Buyers Only Take Pellets?
A small group of buyers, mostly injection molders and extruders, ask for pellets because uniform granules feed straight into their machines. For a fabricator, this is the buyer pool that is hardest to serve: pellets require a full reprocessing line with quality gates on melt flow, moisture, contamination, and color, and off-spec loads get rejected.
We heard this at Foam Expo 2026. Fabricators inside one resin producer's take-back conversation reported that certain buyers in the chain were quoting pellets only, not logs. When that happens, it is usually a signal to find a different buyer or route your densified output through a pelletizing partner, not a signal to become a pellet producer yourself.
Here is the part most equipment marketing skips. Industry pricing guides show pellets earning more per tonne than densified blocks, but that spread pays for a small extrusion operation: the capital cost, footprint, ventilation, staffing, and rejection risk all come out of it. The premium belongs to the pelletizing specialist who runs that operation at scale, and they buy their feedstock as logs and bricks. That is where a fabricator fits in the chain.
How Do Prices Compare Across Logs, Bricks, and Pellets?
Densified blocks and logs generally trade in the range of $0.10 to $0.30 per pound in North America. Pellets list higher, but that figure is before the processing cost of producing them, which is why the net advantage sits with the pelletizing specialist rather than the fabricator. Exact pricing moves with resin markets, region, cleanliness, and polymer type, so treat published ranges as a starting point and get quotes in writing from your actual buyers.
Format | Typical production method | Indicative density | Who buys it | Relative price position |
Logs | Compression (mechanical pressure, unmelted core; AC Series adds a heat-sealed outer shell) | ~300 to 480 kg/m³ (up to 30 lbs/ft³ on the AC Series) | Pelletizers, resin producer buy-back programs | Base market price; premium possible for clean unmelted PE |
Bricks / ingots | Thermal densification (melt and extrude) | ~600 to 800 kg/m³ | Recyclers, exporters, grinders | Similar range per pound; wins on freight per load |
Pellets | Full pelletizing line (extrude, filter, cut) | Solid resin | Molders, extruders, compounders | Lists highest per tonne, but net of the highest processing cost and rejection risk |

How Should a Fabricator Decide Which Format to Produce?
Work backward from the buyer, not forward from the machine. The sequence below is the one we walk prospects through, and it prevents the most expensive mistake in foam recycling: producing a format nobody within freight range wants.
Call buyers before you call equipment vendors. Contact reclaimers, resin producer programs, and brokers within your shipping range. Ask what form they accept, their minimum loads, and their contamination limits.
Get the acceptance spec in writing. "We take PE" is not a spec. Logs or bricks, polymer, density, cleanliness, and price basis should all be on paper before you size a machine.
Match the format to your material. Clean single-polymer PE trim points toward compressed logs. Mixed EPS, EPP, and EPE bead foam points toward thermal bricks.
Run the freight math. Weigh output density against buyer distance. A closer buyer paying slightly less per pound often beats a distant buyer paying more.
Leave the pellet step to a partner at first. Densify in-house, sell to a pelletizer, and revisit in-house pelletizing only if your volume and margins prove out over a year of shipments.
The contrarian take, based on what we see on fabrication floors: chasing the pellet premium is usually the wrong first move for a converter. Your plant makes money fabricating foam, not running an extrusion QC lab. A densifier turns your scrap stream into a sellable commodity with one operator and a fraction of the capital. Let the pelletizing specialists do what they do.
Where JTW Fits in This Decision
JTW International builds both sides of the log-versus-brick choice at our facility in Toccoa, Georgia. The AC Series compactors compress polyethylene foam into dense square logs with a heat-sealed outer shell and an unmelted core, the format buyers want when they plan to reprocess the PE themselves. The AD Series auger densifiers melt and extrude EPS, EPP, and EPE into thermal bricks for buyers who pay on density. Our waste material conveying systems feed either line directly from your cutting operations, so scrap moves from the saw or die press to sellable form without a floor full of bins.
Because we manufacture both formats of machine, we have no reason to push you toward one output. We ask the same question your buyer will: what form do they take, and at what spec? If you are not sure yet, we run test batches on your actual material so you can show a prospective buyer real logs or real bricks made from your own scrap.
Conclusion
Logs, bricks, and pellets are three different products, made on different equipment, sold to different buyers, at different points on the price-versus-processing curve. The fabricators who get paid well for scrap are the ones who confirmed the buyer's format first and bought equipment second.

FAQs
Can one machine produce both logs and bricks?
No. Logs come from compression equipment like the AC Series, which squeezes air out and heats only the outer surface to hold the shape. Bricks come from thermal densifiers like the AD Series, which melt the foam through. Different machines, different output, so confirm your buyer's format before you buy.
Do buyers pay more for bricks than for logs?
There is no automatic premium either way. Bricks are fully melted, so buyers who grind material straight into their process often prefer them; pelletizers often prefer logs with an unmelted core. Published block pricing sits around $0.10 to $0.30 per pound for both. The premium belongs to whichever format your specific buyer asks for.
What contamination gets a load of densified foam rejected?
Tape, paper labels, film laminates, food residue, and mixed polymers. Mixing polystyrene with polyethylene is the costliest mistake because it can downgrade the whole load. Separate streams at the point of cutting and get your buyer's contamination tolerance in writing.
How much more does a trailer of densified foam carry compared to loose foam?
A trailer of loose EPS holds only a few hundred pounds because the foam is roughly 98 percent air. Densified, the same trailer loads up to 40,000 lbs. That gap is why buyers rarely pay for loose foam shipped any real distance.
Should a foam fabricator buy a pelletizing line instead of a densifier?
For most fabricators, no. Pelletizing lines cost several times more, demand extrusion expertise, and off-spec pellets get rejected. Densify in-house, sell logs or bricks to a pelletizing partner, and revisit only if a year of stable volume proves the math.
