What is Plastic waste management?

Plastic waste management refers to the set of processes, policies, and technologies aimed at controlling, reducing, reusing, and recycling plastic materials at the end of their life cycle. This concept covers all stages of a plastic’s lifecycle—from production and consumption to recovery or disposal—with the goal of minimizing environmental impact and promoting more efficient use of resources.

In the plastics industry, plastic waste management has become a key pillar in advancing toward circular economy models. Manufacturers, processors, and end users of plastic components are increasingly adopting strategies that prioritize source reduction, internal reuse of production scrap, and the recovery of materials through mechanical, chemical, or energy recycling.

A fundamental aspect of this management approach is the identification and separation of waste according to polymer type, color, contamination level, and origin. Proper classification facilitates the direct reuse of in-house scrap (such as runners, flash, or rejected parts) or its delivery to external recycling facilities. In injection molding processes, well-planned operations allow reintroducing a portion of recycled material into new production batches without compromising the technical properties of the final parts.

There are several types of recycling processes within an effective plastic waste management system:

• Mechanical recycling: involves shredding, washing, drying, and extruding waste to produce reusable pellets.

• Chemical recycling: breaks down plastics into basic raw materials (monomers or fuels) using thermo-chemical processes.

• Energy recovery: uses the calorific value of non-recyclable plastics as a fuel in cement kilns or controlled incineration plants.

Beyond recycling, plastic waste management also includes source reduction measures, such as designing lighter products, optimizing molding processes, using recyclable materials, and replacing complex plastics with mono-material alternatives. It also involves staff training, preventive equipment maintenance to reduce rejections, and cooperation with suppliers to cut packaging waste and related discards.

At Plásticos Lezo, we actively apply plastic waste management policies across all our operations. We work with certified partners for waste collection and recovery, implement internal collection systems by material type, and monitor waste generation indicators per unit produced. We also develop product solutions using recyclable or recycled materials aligned with our clients’ sustainability goals.

Our approach includes full traceability of waste, from its source to its final destination, ensuring compliance with current regulations and readiness for future environmental requirements. We also participate in innovation projects related to advanced recycling and resource optimization, constantly seeking to reduce our environmental footprint.

In summary, plastic waste management is a shared and strategic responsibility for any company in the sector. It not only addresses growing environmental concerns but also improves operational efficiency, reduces costs, and strengthens corporate reputation. At Plásticos Lezo, we embrace this commitment as an integral part of our operations, driving a cleaner, safer, and more sustainable industrial model.
