Types of Recyclable Plastics

By Seraphim Plastics | July 12, 2026

Plastic plays an essential role in modern manufacturing, packaging, transportation, healthcare, and consumer products. While not every plastic is recycled in the same way, many industrial plastics can be recovered, processed, and returned to manufacturing as valuable raw materials.

For manufacturers, recycling post-industrial plastic scrap isn’t just about sustainability—it’s also an opportunity to reduce disposal costs, recover value from production waste, and support a more circular supply chain.

This guide explains the most common types of recyclable plastics, their applications, and why proper sorting is essential for successful recycling.

Why Plastic Type Matters

Every plastic resin has different physical and chemical properties. Some are designed for flexibility, while others provide high impact resistance, chemical resistance, or heat tolerance.

Because of these differences, plastics must typically be sorted by resin type before mechanical recycling. Mixing incompatible materials can reduce the quality and performance of recycled resin.

Manufacturers that separate plastics during production generally produce higher-value scrap that is easier to recycle.

High-Density Polyethylene (HDPE)

HDPE is one of the most widely recycled plastics due to its durability, chemical resistance, and versatility.

Common products include:

HDPE manufacturing scrap often includes purge material, rejected molded parts, runners, and startup scrap.

Because clean post-industrial HDPE is highly desirable, it is commonly recycled into new industrial products.

Polypropylene (PP)

Polypropylene is a lightweight plastic known for its excellent fatigue resistance and chemical stability.

Common applications include:

  • Plastic totes
  • Automotive components
  • Food containers
  • Buckets
  • Industrial bins
  • Packaging
  • Consumer products

Injection molding facilities frequently generate recyclable polypropylene through sprues, runners, purge material, and off-spec production.

Polyethylene Terephthalate (PET)

PET is best known for beverage bottles, food containers, and packaging, but it is also used in industrial manufacturing.

Common products include:

  • Beverage bottles
  • Food packaging
  • Thermoformed containers
  • Plastic sheets
  • Industrial packaging

Recycled PET is widely used in packaging, fibers, textiles, and other manufacturing applications.

Low-Density Polyethylene (LDPE)

LDPE is flexible and lightweight, making it ideal for films and packaging.

Common applications include:

  • Stretch film
  • Plastic bags
  • Protective packaging
  • Industrial liners
  • Shrink wrap

Clean industrial film generated during manufacturing can often be recycled when kept free from contamination.

Linear Low-Density Polyethylene (LLDPE)

LLDPE offers greater flexibility and puncture resistance than traditional LDPE.

It is commonly used for:

  • Stretch wrap
  • Agricultural film
  • Industrial packaging
  • Protective sheeting
  • Flexible containers

Large manufacturing operations often generate recyclable LLDPE film during packaging and production.

Acrylonitrile Butadiene Styrene (ABS)

ABS is an engineering plastic valued for its strength and impact resistance.

It is commonly found in:

  • Automotive trim
  • Appliance housings
  • Electronic enclosures
  • Consumer products
  • Industrial components

Many manufacturers recycle clean ABS production scrap generated during molding operations.

Polycarbonate (PC)

Polycarbonate is known for its strength, transparency, and impact resistance.

Applications include:

  • Machine guards
  • Safety equipment
  • Medical devices
  • Electronic components
  • Industrial glazing

Although polycarbonate is more specialized than commodity plastics, many post-industrial streams remain recyclable.

Nylon

Nylon is widely used where wear resistance and strength are required.

Common products include:

  • Automotive components
  • Bearings
  • Bushings
  • Gears
  • Industrial equipment
  • Cable ties

Manufacturing scrap from nylon molding operations can often be mechanically recycled.

PMMA (Acrylic)

PMMA, often referred to as acrylic, is valued for its optical clarity and weather resistance.

Common applications include:

  • Displays
  • Signage
  • Machine covers
  • Lighting components
  • Protective panels

Clean production scrap may be recycled into secondary manufacturing applications.

Thermoplastic Olefin (TPO)

TPO is widely used in automotive and industrial manufacturing because it combines flexibility with impact resistance.

Applications include:

  • Automotive bumpers
  • Interior trim
  • Exterior body panels
  • Industrial products

Many automotive manufacturers recycle post-industrial TPO scrap generated during production.

Common Sources of Recyclable Industrial Plastic

Manufacturing facilities often generate recyclable plastic through normal production processes, including:

  • Purge material
  • Sprues
  • Runners
  • Startup scrap
  • Trim waste
  • Flash
  • Off-spec products
  • Regrind
  • Production changeovers

Because these materials are generated in controlled manufacturing environments, they are often cleaner and more consistent than post-consumer plastics.

Factors That Affect Recyclability

Not every plastic load has the same recycling value.

Several factors influence how easily plastics can be recycled:

Material Purity

Single-resin loads are significantly easier to process than mixed plastic streams.

Contamination

Dirt, labels, metal, paper, food residue, and moisture reduce material quality and increase processing costs.

Color

Natural plastics generally have broader end-use applications than colored materials.

Volume

Consistent truckload quantities improve transportation efficiency and processing economics.

Why Manufacturers Recycle Plastic Scrap

Industrial recycling provides benefits beyond reducing landfill waste.

Manufacturers often recycle plastic to:

  • Lower disposal costs
  • Recover value from production scrap
  • Improve warehouse efficiency
  • Support sustainability initiatives
  • Meet customer environmental requirements
  • Reduce dependence on virgin resin
  • Contribute to a circular manufacturing economy

For many facilities, plastic scrap is no longer viewed as waste but as a recoverable manufacturing resource.

Best Practices for Recycling Industrial Plastics

To maximize the value of recyclable plastic:

  • Keep different resin types separated.
  • Separate natural and colored materials whenever possible.
  • Store scrap indoors to minimize contamination.
  • Prevent mixing with metal, wood, cardboard, or general trash.
  • Consolidate material into larger, consistent loads.
  • Work with experienced industrial plastic recyclers.

These practices help improve recycling efficiency while maximizing the value of post-industrial plastic.

Final Thoughts

Many of today’s most commonly used plastics—including HDPE, PP, PET, LDPE, LLDPE, ABS, Polycarbonate, Nylon, PMMA, and TPO—can be successfully recycled when properly sorted and managed.

For manufacturers, understanding the different types of recyclable plastics is the first step toward reducing waste, improving operational efficiency, and recovering value from production scrap. By maintaining clean, consistent material streams and partnering with experienced industrial recyclers, companies can help keep valuable plastic in circulation while supporting a more sustainable manufacturing economy.
