Closed-Loop Recycling – Reearth’s Circular Solution for a Sustainable Future

As plastic pollution increasingly threatens ecosystems, human health, and the global environment, developing efficient and sustainable recycling models has become not only a necessity but also a responsibility shared by businesses worldwide. In Vietnam, Reearth is pioneering a closed-loop recycling system – a model that “closes the circle” of plastic’s life cycle, minimizes waste, and transforms discarded plastics into clean, high-quality recycled pellets for industrial production.

This article provides a comprehensive overview of Reearth’s closed-loop recycling process, the key benefits it delivers, and how it contributes to building a more circular and sustainable economy in Vietnam.

1. What Is Closed-Loop Recycling?

Closed-loop recycling is a waste management system in which reclaimed materials are recycled and reused to produce new products of similar quality, rather than being downcycled, landfilled, or leaked into the environment.

In the plastics industry, this approach is vital to reducing waste and conserving resources. A successful closed-loop cycle ensures that plastic waste is:

• Properly collected

• Accurately sorted

• Thoroughly cleaned

• Processed with advanced technologies

• Converted into high-quality recycled pellets

• Reintroduced as raw materials for new products

This not only helps protect the environment but also reduces reliance on virgin plastic, which consumes significant natural resources and energy.

2. Reearth’s Closed-Loop Process: Systematic – Modern – Transparent

Reearth has designed its closed-loop recycling model based on three core principles: systemization, transparency, and sustainability. Every stage of the process is standardized to ensure consistent quality and high efficiency.

(1) Source Collection & Sorting

Reearth collaborates with manufacturers, industrial zones, collection partners, local communities, and international suppliers to gather post-consumer and post-industrial plastics. The materials are sorted by type—HDPE, LDPE, PP, and others—to optimize later processing steps.

Sorting at the source significantly enhances input quality while reducing energy consumption and processing costs.

(2) Washing & Contaminant Removal

This phase is critical for achieving high-quality recycled pellets. Reearth uses multi-stage washing systems, friction cleaning, and optimized temperature treatment to remove dust, ink, adhesives, and organic residues.

All cleaning procedures are conducted in a closed system to minimize odors and prevent secondary pollution.

(3) Grinding – Drying – Pelletizing

After being cleaned, plastics are shredded into flakes, dried, and fed into a high-temperature extrusion system. The material is melted, filtered using pressure filtration technology, and pelletized according to strict specifications.

Reearth’s recycled pellets offer:

• High purity

• Clear or opaque colors upon request

• Stable mechanical properties

• Zero contamination from metals, paper, or fibers

(4) Returning to Production – Completing the Circular Loop

Reearth’s recycled pellets are supplied to businesses across various sectors, including packaging, household goods, consumer products, and industrial manufacturing. At this stage, the plastics have completed a full closed-loop cycle: waste → recycling → raw material → new product.

3. Benefits of Reearth’s Closed-Loop Model

Reducing Plastic Pollution

Closed-loop recycling significantly lowers the amount of plastic waste sent to landfills or leaked into rivers, seas, and oceans. It is a long-term and sustainable solution to combat plastic pollution.

Saving Resources and Energy

Producing virgin plastic requires large amounts of petroleum and energy. Recycled plastic helps:

• Reduce pressure on natural resources

• Lower carbon emissions

• Decrease production costs for businesses

High-Quality Recycled Materials

By using a standardized, modern closed-loop process, Reearth ensures that its recycled pellets meet the requirements of various industries. Consistent quality empowers businesses to confidently integrate recycled materials into their production lines.

Promoting a Circular Economy in Vietnam

Reearth’s model aligns with Vietnam’s national strategy on circular economy development. By transforming domestic plastic waste into valuable recycled materials, Reearth reduces dependence on virgin imports and supports a greener economic transition.

4. Reearth – A Trusted Recycling Partner for Businesses

With an extensive partner network and a team of experienced professionals, Reearth is committed to delivering reliable, end-to-end recycling solutions. More than a recycling provider, Reearth is a sustainability partner, helping businesses manage waste responsibly and reduce their carbon footprint.

5. A Greener, More Sustainable Future

Reearth’s closed-loop recycling system represents both a technological solution and a long-term vision. By closing the loop of plastic’s life cycle, Reearth extends material lifespan, eases environmental pressure, and accelerates Vietnam’s shift toward a circular, resource-efficient economy.

In a world facing rapid industrialization and growing consumption, closed-loop recycling is not only an environmental responsibility but also an opportunity for businesses to build a more sustainable and resilient future.
