Plastic Waste Recycling and Recovery

Recycling and Regeneration of Plastic Waste: Direct & Modified Reuse Methods

Recycling and reuse of waste plastics is the primary method adopted worldwide for plastic waste recovery, due to its relatively low technical investment and cost. This approach has mature industrial processes in place. Compared with modified regeneration, direct reuse is simpler and more cost-effective, making it the most common method. However, modified regeneration is considered the future development trend as it significantly improves product performance.

⸻

1. Direct Recycling (Direct Reuse)

Direct recycling involves sorting, cleaning, crushing, and pelletizing waste plastics before directly molding them into new products. In some cases, additives such as stabilizers, anti-aging agents, and colorants are added to improve processing, appearance, or resistance to aging. However, these additives do not fundamentally improve the mechanical properties of the recycled plastic.

For example, a Japanese construction company processes waste foam plastics by crushing and heating them with infrared radiation, reducing their volume by more than 80%. The material is then mixed with special cement to produce a “rice cracker”–like sound insulation board, offering low-cost, high-efficiency noise reduction for various building applications.

⸻

2. Modified Recycling (Performance-Enhanced Reuse)

Modified recycling improves the properties of recycled plastics via mechanical blending or chemical grafting, such as toughening, reinforcing, compounding, particle activation, crosslinking, chlorination, and other chemical modifications. This process enhances performance — especially mechanical strength — enabling the production of higher-grade recycled products. However, it requires more complex processes and specialized equipment.

Almost all thermoplastic waste plastics can be collected, sorted, cleaned, crushed, dried, melted, and then reprocessed into recycled plastic sheets, pipes, rods, components, containers, and more. For instance, banned EPS foam food containers can be cleaned, dried, crushed, defoamed via a single-screw extruder, pelletized, and then blended with LDPE to create LDPE/PS composites with higher tensile strength, improved elongation, and impact resistance — suitable for products like cable cover boards and household items.

⸻

3. Chemical Degradation Technologies

Chemical degradation breaks down the polymer chains of waste plastics into monomers or other basic organic raw materials. This process depends heavily on degradation temperature, catalysts, and specialized equipment.

3.1 Depolymerization

Depolymerization returns plastics to monomers or chemical feedstocks via hydrolysis or alcoholysis. This method requires clean waste plastics, removal of additives, and purification of monomers.

3.2 Pyrolysis

Pyrolysis is the thermal decomposition of plastics at high temperatures (above 500°C) in the absence of oxygen.
For example, a German company operates a 10t/day pilot plant that heats mixed waste plastics at 699–800°C for 30 minutes, yielding 35–58% diesel and 23–40% gas. Research from China University of Petroleum shows that pyrolyzing waste polyethylene can produce 50–90% wax, which offers higher economic returns than producing oil.

3.3 Hydrogenation

Hydrogenation involves breaking down plastics under high hydrogen pressure (around 30MPa) at temperatures below 500°C. This produces liquid fuels of lower purity than pyrolysis but can be directly refined in oil refineries. However, it requires strict pre-treatment, separation, and costly equipment.

3.4 Gasification

Gasification degrades waste plastics at extremely high temperatures (up to 1500°C) into CO and H₂ gas, which can then be used to synthesize methanol and other chemical products.

⸻

Conclusion

From low-cost direct reuse to high-tech chemical recycling, plastic waste regeneration offers a sustainable pathway for reducing environmental pollution and creating valuable products. As global environmental regulations tighten, modified recycling and chemical recovery technologies will play an increasingly important role in the circular economy of plastics

What is PE Sheet? Features, Applications, and Price
PE sheet, also known as polyethylene board, is widely recognized for its high toughness, tensile strength, corrosion resistance, low-temperature performance, and excellent wear resistance. It is extensively used in industries such as chemical processing, clothing, packaging, food, gas transportation, water supply, sewage treatment, agricultural irrigation, mining, and oilfield operations, as well as telecommunications. In particular, HDPE sheets are extensively applied in gas pipeline systems. However, many people still have only a partial understanding of PE sheets — so, what exactly are they, and are PE sheet prices expensive? Let’s find out.
PE sheet offers excellent resistance to most household and industrial chemicals. Some chemicals, such as strong oxidizing agents (e.g., concentrated nitric acid), aromatic hydrocarbons (e.g., xylene), and halogenated hydrocarbons (e.g., carbon tetrachloride), may cause chemical corrosion, but overall, HDPE demonstrates superior chemical stability. It is non-hygroscopic, has outstanding water vapor barrier properties, and is often used for packaging. HDPE also has excellent electrical properties, particularly high dielectric strength, making it ideal for wire and cable insulation. Medium- to high-molecular-weight grades have exceptional impact resistance, even at extremely low temperatures down to -40°F.
One of the unique strengths of HDPE lies in the balance of four key variables: density, molecular weight, molecular weight distribution, and additives. By adjusting these factors, and using different catalysts, manufacturers can produce HDPE grades tailored for specific performance requirements — achieving the best balance between strength, durability, and processing ease.
PE sheets can also be filled, flame-retardant, modified, or surface-textured (embossed, frosted). LDPE (low-density polyethylene) is softer, has lower mechanical strength and melting point, and is suitable for making films and cable insulation. HDPE (high-density polyethylene) is more rigid, has higher mechanical strength and melting point, and is suitable for hollow products, injection-molded parts, and even ice rink barrier boards. Available thickness ranges from 1mm to 350mm, and colors include natural, white, blue, yellow, gray, black, green, and more.
Production Tips for High-Quality PE Sheets
When manufacturing PE sheets, both raw material selection and processing techniques are crucial. Since polyethylene is an inert polymer with poor melt flow, choosing raw materials with added lubricants (such as stearic acid or metallic stearates) improves moldability and prevents air bubbles.
In processing, precise feed measurement is key — avoid under- or over-feeding. For PE sheets, a higher feed volume combined with high-pressure, fast injection molding produces the most uniform and durable boards. The result is a PE sheet with a smooth finish, no voids, and consistent quality.
