Plastic Waste Recycling for Businesses: Types, Processing, and Revenue

Updated on: 4th March 2026 By:

Plastic waste is the most diverse and commercially complex recyclable stream a business encounters. Unlike cardboard, where the material is essentially the same across all sources and buyers are straightforward to find, plastic waste covers dozens of polymer types with different market values, different processing requirements, and different buyer pools. A pallet of mixed plastics has almost no market value; the same weight separated by polymer type, baled cleanly, accesses markets that pay well for consistent specification material.

This article covers the plastic waste streams most commonly generated by UK businesses, the processing approach that extracts maximum value from each, and the equipment that makes commercial-scale plastic baling practical. It is written for operations managers and sustainability leads at businesses that currently dispose of plastic waste in general skips and want to understand what it would take to turn that cost into a revenue line.

The Main Commercial Plastic Waste Streams

Plastic Waste Recycling for Businesses: Types, Processing, and Revenue

Businesses generate plastic waste in several distinct forms, each with its own market and processing requirements. Understanding which streams you generate, and in what volume, is the starting point for designing a plastic recycling programme with a credible financial return.

Plastic Type	Common Business Sources	Market Value (relative)	Processing Method
LDPE film / shrink wrap	Pallet wrap, polythene bags, packaging film	Moderate; clean film attracts good rates	Baling in dedicated film baler
HDPE rigid (bottles, containers)	Cleaning products, food service, retail	High for clean, separated HDPE	Baling; granulation for higher value
PET bottles	Hospitality, food service, offices	High for clear PET; lower mixed	Baling by colour / grade
PP (polypropylene)	Packaging, strapping, crates	Moderate; clean PP bales viable	Baling after separating from mixed
Mixed rigid plastics	General packaging, product protection	Low to nil unless separated	Compaction for disposal; separation for value
EPS / polystyrene	Electronics, appliance packaging, food trays	Low loose; significantly higher densified	Dedicated densifier or baler

Why Separation Is the Key to Plastic Recycling Revenue

The economics of plastic recycling are driven by material purity. A bale of clean, single-polymer LDPE film commands a meaningful market price because the recycler receiving it can process it without the costly sorting and contamination removal step. A bale of mixed plastics requires sorting before it can be processed, which reduces the value to the original generator or makes the material unmarketable at any realistic price. Separation at source, before the materials enter the waste stream, is what creates value in commercial plastic recycling.

For most businesses, the practical starting point is separating the two or three highest-volume plastic streams they generate. For a food manufacturer, that might be LDPE pallet wrap and HDPE containers. For a retailer, it might be LDPE film and PET bottles. Starting with the streams that are cleanest, easiest to separate, and most valuable, then adding streams as the programme matures, is more effective than attempting comprehensive plastic sorting from day one.

For LDPE film and shrink wrap, Gradeall’s vertical baler range provides a cost-effective way to compact large volumes of film into dense, consistent bales. The G-Eco 500 is particularly well suited to mixed plastics baling in commercial settings where multiple polymer types are handled.

LDPE Film: The Highest-Volume Plastic Opportunity for Most Businesses

LDPE film, the material of pallet stretch wrap, polythene bags, and most flexible plastic packaging, is the plastic waste stream with the best combination of volume and market accessibility for most UK businesses. It is generated in large volumes at retailers, distributors, and manufacturers; it is relatively easy to separate from other materials; and clean film bales have established buyers at processing facilities throughout the UK.

The challenge with LDPE film is that it is voluminous but light. A skip full of loose pallet wrap represents a small fraction of a tonne. Baling compresses film to a density that makes transport and handling economically viable for recyclers, which is why unbaled film has almost no collection market while baled film does. A baler that produces dense film bales is the enabling technology for any serious LDPE film recycling programme.

“Film recycling is the area where we see the biggest gap between what businesses throw away and what they could get for it,” says Conor Murphy, Director of Gradeall International. “A large logistics or retail operation discarding two tonnes of pallet wrap per week is looking at a significant annual revenue opportunity with a baler that has a payback period of 12 to 18 months in most cases.”

Rigid Plastics: HDPE and PET

HDPE and PET are the highest-value plastic streams that most businesses generate, but they are typically generated in smaller volumes than film. Food service, hospitality, and office environments generate PET bottles in significant numbers. Cleaning products, liquid containers, and crates generate HDPE. For businesses generating sufficient volume, separate baling by polymer type maximises value. For smaller volumes, accumulating in dedicated containers and arranging periodic collection to a sorting facility is the practical approach.

For businesses seeking a complete waste equipment solution covering both plastic and other waste streams, Gradeall’s compactor range provides general waste compaction alongside the baler range, allowing a single equipment installation to address both recyclable and residual waste management needs.

Frequently Asked Questions

How clean does plastic need to be for recycling?

Plastic recyclability thresholds vary by material type and buyer, but a general standard is that plastic should be free of significant food contamination, be of a consistent polymer type within a bale, and be dry. Light contamination (labels, minor residue) is typically acceptable; heavy food contamination, wet material, or significant mixed polymer content reduces bale value. Rinse food containers before adding them to the plastic recycling stream where practical.

What happens to plastic that cannot be recycled?

Mixed or heavily contaminated plastics that cannot be recycled are sent to energy recovery through refuse-derived fuel (RDF) processing, or to landfill in the absence of energy recovery options. Compacting non-recyclable plastics before sending them to general waste reduces skip volume and collection frequency, which lowers disposal cost even for materials that cannot be recycled. A compactor for residual plastic waste is a cost-reduction tool even when the material has no recycling value.

Is there a minimum volume of plastic for a collection programme to be viable?

For LDPE film, a business generating 200 kg or more per week typically justifies a dedicated baling programme with regular collection. Below this, accumulation in a sealed container for monthly collection by a film recycler may be more practical than continuous baling. For HDPE and PET, the minimum viable volume is lower because the higher value per tonne makes smaller quantities worth collecting. Contact a local plastic recycler for guidance on minimum collection volumes for the specific polymer types you generate.

Can I bale different plastics in the same baler?

Technically yes, but commercially you should not mix polymer types in a single bale. Buyers of plastic bales want consistent single-polymer material. A bale containing mixed LDPE and HDPE, for example, has lower value than separate LDPE and HDPE bales. If your baler is used for both cardboard and plastic, bale each material separately and label bales clearly by material type. Run the baler to empty before switching between materials.

Do plastic bales need to meet any certification standards?

There are no mandatory certification standards for plastic bales in the UK equivalent to PAS 108 for tyre bales. However, some buyers have their own incoming quality specifications covering bale weight, density, moisture content, and polymer purity. Establishing the specification requirements of your buyer before starting production avoids rejected loads. European and international buyers may have stricter specifications than domestic UK buyers; confirm requirements before committing to an export-focused plastic recycling programme.
