Recycling Waste Cable Plastics into Plastic Pipes and Wood-Plastic Profiles
my country generates over 5 million tons of waste cable annually. The plastic insulation on these cables' outer layers can be converted into high-purity recycled plastic pellets through six processes, including sorting, cleaning, and pelletizing. Yongte Plastic Machinery's pelletizing, pipe, and wood-plastic profile equipment plays a key role in this conversion process, providing reliable technical support for the efficient conversion of recycled pellets and achieving a complete closed-loop system from recycling to finished products. This model not only effectively reduces environmental pressure but also creates significant economic benefits.
After being graded according to purity, the recycled pellets are widely used in pipes and wood-plastic profiles. Thanks to its excellent adaptability to the properties of recycled materials, Yongte's equipment has become a key player in the production of infrastructure, home improvement, and outdoor landscaping products. In pipe applications, recycled PE and PVC are already well-established for low-pressure, non-potable water applications. Using first-grade recycled PE granules as raw material, Yongte twin-screw granulation equipment shears and kneads them at 180–200°C, effectively eliminating uneven melting and maintaining a stable melt index of 0.3–0.5g/10min. Processing in specialized PE pipe equipment results in pipes with a tensile strength of up to 12MPa, fully meeting national standards. Municipal projects using this type of recycled PE drainage pipe have reduced costs by 30%, saving over one million yuan per project, while maintaining performance comparable to virgin pipe.
Recycled PVC pipe is primarily used for wiring in home renovations. To address the potential for impurities in recycled material, Yongte installs a precision filter at the extruder inlet to effectively ensure surface quality and adjusts the screw speed to accommodate the material's processing characteristics. This type of recycled PVC conduit is priced 0.8 yuan lower per meter than virgin products, achieving significant annual sales and gaining widespread market acceptance.
For wood-plastic profiles, recycled plastic and wood fiber can be mixed in a 7:3 ratio to create flooring, wallboard, and other products. Yongte's wood plastic pelletizing equipment solves the problem of material delamination by adding a compatibilizer. Its extrusion equipment utilizes a "high-temperature shaping + vacuum cooling" process, maintaining a stable product density of 1.1–1.3 g/cm³. It offers excellent mildew and insect-resistant properties, while maintaining significantly lower maintenance costs than solid wood. Some scenic spots have seen costs reduced by up to 30% compared to solid wood by adopting recycled wood plastic flooring, demonstrating excellent overall benefits. Low-purity recycled material can be used in outdoor items such as flower boxes and trash cans. Yongte's corresponding small-scale extrusion equipment features low energy consumption and a small footprint, making it suitable for flexible deployment by small and medium-sized enterprises.
Industry reports indicate that the scale of recycled plastics from waste cables will exceed 8 billion yuan by 2024, with recycled pipes and wood plastic profiles contributing over 60% of this output value. Yongte's equipment, thanks to its excellent compatibility with recycled materials, has secured a significant share of the recycling equipment market. Notably, the new generation of equipment features upgraded features such as online detection and energy-saving features, further improving production quality and sustainability.From an overall perspective, every ton of recycled plastic insulation can produce 0.8 tons of recycled material, which can then be made into 200 square meters of wood-plastic flooring or 300 meters of conduit. This is equivalent to reducing the consumption of 0.6 tons of virgin plastic and 0.8 cubic meters of wood, with a resource utilization rate exceeding 90%. This complete "recycling-processing-finished product" model not only achieves efficient resource circulation, but also provides a practical and feasible industrial path for green and low-carbon development.
