Is PVC Recyclable and What the Process Requires

PVC is recyclable and mechanically recycled PVC is an established industrial material, but it cannot travel through general household recycling. This article explains why PVC behaves unlike every other volume plastic, how rigid and flexible grades are two different feedstocks with different additive recipes, the three independent reasons it needs its own line, what a PVC granulating and pelletizing line actually controls from magnetic separation through gravimetric stabiliser dosing to air-cooled die-face cutting, the four variables that decide pellet quality, and where recycled PVC ends up.

Is HDPE Recyclable and How LDPE Differs

HDPE is one of the two most recycled plastics in the world, and the reason is handling behaviour rather than chemistry. Rigid containers sit above the screen cut at a sorting facility, survive baling, float clear of PET and PVC in a water tank, and split into a premium natural grade and a coloured grade. LDPE is the same polymer family arriving as film, and it runs on completely different hardware. This article covers what makes rigid HDPE easy to recover, what LDPE is and why it takes a separate route, the four ways a mixed intake breaks both lines, and how a rigid washing line and a film washing line differ stage by stage.

What Is HDPE and Why It Dominates Rigid Packaging

HDPE is high-density polyethylene, a thermoplastic whose almost unbranched chains pack into crystalline regions and give it stiffness, chemical resistance, a strong moisture barrier and toughness below freezing. This article works outward from that structure — what the density band really measures, which grade families exist and why they are not interchangeable, where HDPE wins in rigid packaging and buried pipe, how it behaves on a recycling line, what it cannot do, and how it differs from PVC.

Is Plastic Wrap Recyclable and Why It Jams Sorting Lines

Whether plastic wrap is recyclable depends entirely on which wrap is meant. Kitchen cling film is one of the few plastics with essentially no recycling route, while industrial pallet stretch wrap is clean single-resin LLDPE baled at source and one of the more valuable film feedstocks a recycler can buy. This article separates the two materials, explains the two distinct ways film defeats sorting equipment, sets out the four properties that make warehouse stretch film a premium feedstock, and lists what actually causes a wrap load to be rejected.

Are Plastic Bags Recyclable and What Happens to Them

Plastic bags are recyclable as a material but almost never through a kerbside bin, and the two answers are about different things. This article separates the polymer from the collection system, explains why a bag behaves differently from a bottle of the same resin, what a loose bag does to disc screens and near-infrared sorters inside a material recovery facility, how a film washing line processes baled bags into dry flake, why densifying is a stage rather than an accessory, and where printing ink and multilayer laminates set the ceiling on the pellet grade.

How a Plastic Recycling Business Actually Makes Money

A plastic recycling business earns its margin in five specific places — the buying spread, yield, the grade mix it can certify, the hours the line genuinely runs, and how cheaply its residues leave the site. This article works through each one using published SUHUI washing and pelletizing line figures, and explains why four of the five are operating disciplines rather than market conditions.

Is Plastic Recycling Profitable and What Decides It

Whether plastic recycling is profitable is an output of four numbers, not a property of the industry. Two of them belong to your market and two come from the equipment. This article gives the published energy, water and labour figures behind conversion cost per tonne, a break-even worksheet with the market-dependent rows left for you to fill, the variables that move the answer most, and the situations where the maths does not work at all.
