What Injection Molding Scrap Does Carlin Waste Recycling Buy?
Types of Injection Molding Plastic Scrap We Accept
We buy clean, identifiable post-industrial plastic scrap generated by injection molding operations. Common materials include off-spec resin, regrind, purges, runners, sprues, rejected parts, and production scrap.
- Polypropylene (PP): We buy PP injection molding scrap in forms such as regrind, runners, sprues, rejected parts, purges, and off-spec resin. Natural and separated-color material is generally easier to market.
- High-Density Polyethylene (HDPE): We purchase HDPE scrap generated during the production of injection-molded caps, containers, fittings, and other rigid components. Accepted forms may include regrind, parts, runners, and production scrap.
- Low-Density Polyethylene (LDPE): We review clean LDPE injection molding scrap, including rejected components, purges, and regrind, when it is properly separated from other resin types.
- Nylon 6 and Nylon 6/6: We buy clean post-industrial nylon Injection Molding Scrap operations, including off-spec resin, regrind, parts, runners, sprues, and purges. The material must be clearly identified by grade.
- Polystyrene (PS): We purchase clean, separated polystyrene scrap generated during injection molding, including rigid parts, runners, sprues, and regrind.
- Polyethylene Terephthalate (PET): We review clean PET scrap generated during injection molding, including rejected preforms, runners, regrind, and off-spec resin.

What Information Should I Send Before Getting a Quote?
Before getting a quote, the information you need to send us to sell injection molding scrap is:
- Material type: PP, PS, nylon, HDPE, LDPE, PET, or another resin generated by your injection molding operation.
- Material form: Pellets, regrind, flake, purge, rejected parts, sprues, runners, or a combination of these.
- Grade and color: Natural, colored, filled, reinforced, blended, or other known resin specifications.
- Condition: Clean and separated, lightly contaminated, or mixed with other materials. Let us know about any mold release, fillers, colorants, or foreign material.
- Approximate volume: Total pounds or tons available, or the average amount generated per load or each month.
- Facility location: City and state, along with any pickup, dock, or scheduling requirements.
- Photos: Images showing the material’s condition, storage method, and packaging help us evaluate the load and provide a more accurate quote.
How to Prep Your Injection Molding Scrap Before You Sell
To prepare injection molding scrap for sale, follow this step-by-step guide:
Step 1: Separate Scrap by Resin Type
Keep PP, PS, nylon, HDPE, and other resins in their own labeled containers. Assigning a labeled container to each resin as soon as it comes off the press is the single easiest way to protect the value of your scrap before it ever leaves the building.
Step 2: Remove Contamination Before Storage
Take out metal inserts, labels, mold release residue, and any foreign material before the scrap goes into storage, not after it’s already been sitting for weeks.


Step 3: Store in a Consistent, Moisture-Controlled Manner
If material is ground on-site, keep particle size consistent and store it away from moisture, especially for nylon and other hygroscopic resins that degrade quickly when wet.
Step 4: Log Volumes and Resin Details Before Pickup
Track approximate weights and resin types per container as they accumulate. Having this documented before pickup speeds up quoting, keeps your paperwork aligned with what actually ships, and gives your team a running record that’s useful, particularly if your facility needs to report recycling volumes for ESG or sustainability purposes.
How Much Is Injection Molding Scrap Worth Per Pound?
Injection molding scrap prices in the United States fluctuate from month to month. The best way to estimate how much your injection molding scrap is worth is to request a direct quote.
What Factors Affect the Price of Injection Molding Scrap?
The price of injection molding scrap is affected by:
- Resin type and grade, engineering resins like nylon typically command different pricing than commodity resins like PP or PS, and even within a single resin, natural versus filled or colored grades can move independently of each other.
- Cleanliness and contamination, mold release, colorants, fillers, and foreign material all reduce value, sometimes significantly, since buyers price in the cost of additional processing needed to make the material usable.
- Form, clean, uniform regrind is generally worth more than mixed purge or unsorted rejected parts, because it requires less handling before it can go back into a production process.
- Color, natural and single-color materials usually offer more marketing options than mixed-color loads.
- Volume and consistency, larger, recurring volumes may attract more competitive offers than sporadic, one-off loads, since buyers can plan around a predictable supply.
- Current market conditions, virgin resin pricing, feedstock supply, and overall demand all shift recycled values from one month to the next, sometimes by a wide margin, even for the same resin and grade.
