HDPE Plastic (#2)
Milk bottles and cleaning product containers are the everyday face of HDPE, and the single biggest factor in what a load is worth isn't volume or condition, it's whether the plastic is natural or coloured. Here's why that distinction matters so much, and how to sell HDPE properly.
HDPE, high-density polyethylene, is a stiffer, more opaque plastic than PET, marked with the number 2 inside the recycling triangle. Milk bottles are the most recognisable example, alongside many cleaning product, shampoo, and detergent containers, and some pipe and industrial packaging. ScrapTrade's live-priced category covers natural, uncoloured HDPE specifically, clean containers without dye or heavy pigmentation.
Beyond household packaging, HDPE turns up in industrial and commercial contexts too, pipe offcuts, drums, crates, and IBC (intermediate bulk container) totes are all the same base plastic. That stream is genuinely different from post-consumer packaging, often cleaner and less contaminated with product residue, but it also comes with its own preparation step, metal or steel reinforcing bands, bungs, and valve fittings need to come off before the load is baled or graded. Construction, manufacturing, and logistics businesses generating this kind of volume are a real fit for ScrapTrade's HDPE category alongside the recycling and collection operators handling packaging streams. Checking the live reference price before agreeing to a quote applies just as much to this industrial stream as it does to household-origin packaging.
Natural HDPE can be reprocessed into almost any colour a manufacturer needs, white, black, or anything in between, which makes it genuinely flexible feedstock. Coloured HDPE, by contrast, can really only be reprocessed into similarly dark or specifically-coloured products, since you can't reliably bleach a coloured plastic back to natural. That flexibility gap is the entire reason natural HDPE commands a real premium over coloured, even though the base plastic is chemically identical.
A small amount of coloured material mixed into a mostly-natural load is generally tolerated, but a genuinely mixed load prices toward the lower, coloured-inclusive rate. Sorting out obviously coloured containers before baling protects the value of the natural material you've got.
Natural HDPE has a milky, translucent-white appearance, not perfectly clear the way PET is, but distinctly different from the solid, opaque colours of dyed HDPE. Milk bottles are the clearest everyday reference point, that characteristic slightly-cloudy white is what natural HDPE looks like before any colourant is added.
Rinsing out residual product before baling matters here too, cleaning product and detergent containers in particular can leave chemical residue that affects how a buyer assesses the load. A quick rinse is a small step that protects the value of genuinely natural material.
ScrapTrade's live-priced HDPE category is specifically natural, uncoloured containers, clean and baled. Coloured HDPE, or a genuinely mixed load, is worth listing as mixed plastic instead, describing it accurately gets a more confident offer than an optimistic one. See our full plastic scrap guide for how this compares to PET and mixed plastic.

Brisbane and Perth both carry substantial population bases and established kerbside and commercial recycling infrastructure that genuinely generates HDPE volume at a bulk-recycler scale.
Neither city is a requirement. Recycling operators and collection businesses generate this material anywhere in Australia, and ScrapTrade connects buyers and sellers nationally regardless of where a listing is posted from.
HDPE recycles into a genuinely wide range of new products, from bottles to pipe to outdoor furniture, using meaningfully less energy than producing virgin plastic from raw petrochemical feedstock. Natural material sits at the top of that value chain precisely because it can go into any of those applications, which is exactly why keeping it properly sorted and uncontaminated matters more here than the effort might suggest.
Natural HDPE mixed with even a modest amount of coloured material often gets priced at the lower, blended rate by a buyer who'd rather not sort it themselves. On ScrapTrade, you describe your material's colour and condition properly, then list your baled load at a fixed price, run it as a live auction so verified buyers compete for it, or negotiate directly, negotiation is on by default on every listing. Every listing is GPS-video verified before it goes live, and payment sits in escrow from the moment a deal is confirmed until pickup or delivery is done, so neither side is exposed first. The full case for why that beats a single yard quote is on Why Choose ScrapTrade and Trust & Safety.
Milk bottles are the classic example, along with many cleaning product, shampoo, and detergent containers, plus some pipe and general industrial packaging. It's marked with the number 2 inside the recycling triangle, and is generally a stiffer, more opaque plastic than PET.
Because natural (uncoloured) HDPE can be reprocessed into almost any colour a manufacturer wants, while coloured HDPE can only really be reprocessed into similarly dark or specific-coloured products. That flexibility is exactly why natural HDPE commands a real premium over coloured HDPE, even though they're chemically the same base plastic.
A small amount is generally tolerated, but a genuinely mixed load prices toward the lower, coloured-inclusive rate rather than the natural premium. Sorting out obviously coloured containers before baling, where practical, protects the value of the natural material.
Yes, for the same reason, loose containers are mostly empty space and expensive to transport relative to their weight. Baling compresses HDPE into dense, transportable blocks that are genuinely economical to move and process at volume.
Recycling and collection businesses consolidating genuine volume, similar to the other bulk-packaging categories on the site. A household's worth of milk bottles isn't the target audience here, kerbside council recycling collection is the more practical path for that scale.
Yes, ideally. Cleaning product bottles often ship with a trigger sprayer or pump cap that contains a metal spring and a dip tube, both genuine contamination in a plastic bale if left attached. Milk and juice bottle caps are a simpler swap, usually a different plastic resin (polypropylene) to the bottle itself, and are worth separating where practical for the same reason.
Both are established, widely-recycled plastics with real demand, and which one prices higher shifts with market conditions on both sides. Natural HDPE's premium over coloured HDPE tends to be the bigger factor within the category itself, while PET's overall volume is boosted by container deposit scheme collection. Checking a live reference price for both is the reliable way to know which is worth more at any given time, see the PET Plastic Scrap page for the comparison.
