What's the difference in value between HDPE, PET, and PP plastic scrap?
Short answer: These three common plastic resin types generally have different market values driven by how widely they're used in manufacturing and how established the recycling infrastructure is for each — PET and HDPE tend to have well-established, higher-value recycling markets due to their widespread use in bottles and containers, while PP's recycling market, though growing, has historically been somewhat less developed, though exact relative values shift with market conditions.

PET, commonly used in beverage bottles, and HDPE, common in milk jugs and detergent bottles, both have long-established, high-volume recycling markets because of how widely they’re used in consumer packaging — this maturity generally supports stronger, more consistent pricing.
Where PP fits into this picture
Polypropylene, used in items like yogurt containers and bottle caps, has a growing but historically less developed recycling market compared to PET and HDPE, which can mean less consistent demand and pricing — this has been improving as more reprocessing capacity comes online for PP specifically.
Why relative values still shift over time
Recycling infrastructure and end-market demand for each resin type keep evolving, so the relative value ranking between these three plastics isn’t fixed permanently — checking current rates for your specific resin type with a buyer remains more reliable than relying on general assumptions about which plastic is “worth more.”
How ScrapTrade Makes This Easier
Checking current rates for your specific resin type across a few ScrapTrade buyers gives you an accurate, up-to-date picture rather than relying on general assumptions about relative plastic values.
