The main raw material of this test machine is LDPE film. During the operation of the equipment, the feeding is smooth, the size of the discharged fragments is uniform, and the crushed products can be directly sold as recycled raw materials or enter the downstream deep processing process. The output data is based on the LDPE film test, and the actual production capacity will fluctuate according to the material.

In the PET bottle recycling and washing line process, although many links have been automated, there are still some key links that need to be manually operated or assisted by humans to ensure the quality and production efficiency of the final PET bottle flakes. The following are the main tasks that must be completed by manual operation. For example: feeding (unpacking and feeding), sorting PET bottles (sorting colors and materials) and collecting PET flakes.

Kitech KSP series pelletizing system is a plastic recycling solution designed specifically for rigid plastic waste. Its integrated plate filtration technology can effectively remove pollutants and melt impurities during the pelletizing process without expensive pre-cleaning or separate filtration steps. The equipment is suitable for processing rigid plastic flakes such as PP, PE, ABS, PS, HIPS, PC, etc. Its final finished pellets can be used in injection molding, blow molding, film blowing, and pipe extrusion production lines, enabling customers to achieve a closed-loop plastic recycling and reuse process. Kitech KSP series is easy to operate, maintain, and overhaul, without complex operations, and low learning costs for workers.

In the PET bottle washing and recycling production line, the crusher blade is a key component of the crushing equipment. Its service life and replacement time are crucial to the equipment performance and production efficiency. The following is some professional knowledge about the blade material, sharpening frequency and replacement cycle.

Kitech Machinery's KSP180 Plus single-stage pelletizing system has successfully processed recycled polypropylene (PP) battery cases at a rate of 1,500 kg/h during factory trials. Attending clients observed seamless operation and commended pellet quality, prompting detailed technical consultations with Kitech's engineering and sales personnel.

01 Global cities are seriously polluted by plastic

A recent environmental science paper published in the internationally renowned academic journal Nature stated that researchers have established and published a comprehensive list of large plastic pollution at the city scale, revealing the distribution of plastic waste pollution hotspots in more than 50,000 cities around the world.



Based on the results of the study, it is estimated that 52.1 million metric tons of large plastics are discharged into the environment each year, about 57% are burned in the open air, and 43% are unburned fragments. Discarded garbage is the largest source of plastic pollution in the global north, while uncollected waste is the main source in the global south.



So, where do these discarded plastic bottles go? Unfortunately, although up to 1 million plastic bottles are sold every minute worldwide, less than half of the discarded plastic bottles can be effectively recycled and used. Among them, only 7% of plastic bottles are recycled and made into new bottles. Most plastic bottles are either mixed with garbage and landfilled or flow into the ocean, causing serious environmental problems.

1. Accurate and efficient, turning waste into treasure

Kitech Machinery AGC1500 industrial crusher is specially developed and designed to cope with the increasingly severe plastic foam waste. Its sturdy and durable metal appearance is designed for EPS, EPE and EPP materials, and can efficiently crush large foam waste into reusable plastic fragments, which is ideal for recycling, storage or reuse in the manufacturing industry. The AGC1500 crusher can not only crush plastic foam alone, but also can be used with belt conveyor, blasting system, silo system, foam compactor or foam thickener to further reduce the volume of the foam material, thereby simplifying the storage and transportation of the foam material and reducing costs.

Thickening equipment can thicken recycled plastic PET chips, and is usually used in PET washing and granulation production lines, which can realize a closed-loop industrial chain model from recycling, washing, granulation, thickening, and purification.

This week, Kitech Machinery successfully validated its AGSS series shredding system tailored for agricultural film recycling. Engineered for heavy-duty processing, the AGSS1600 single-shaft shredder features a robust rotor design optimized for high-tensile materials such as stretch films, FIBCs (bulk bags), fishing nets, and rigid plastic pallets. With an industry-leading throughput of 1500 kg/h, this system redefines efficiency in post-consumer plastic recovery across diverse sectors.

As the world intensifies efforts to combat plastic waste and transition toward sustainability, China has emerged as a pivotal player in advancing the plastic circular economy. According to *Plastics - the Fast Facts 2023* published by Plastics Europe, global plastic production reached 400 million tons in 2022, with fossil-based plastics still dominating at 90.6%. However, a promising shift is underway: recycled plastics now account for 8.9% of global output, signaling accelerating momentum for circularity. Notably, China contributes 24% of the world' s post-consumer recycled plastics production, solidifying its leadership in this transformative sector.

In PET bottle recycling systems, optimized label separation constitutes a fundamental prerequisite for efficient downstream processing. As critical preprocessing units, delabeling machines directly influence material purity levels by effectively removing diverse label substrates. This technical analysis examines contemporary delabeling methodologies, their operational parameters, and strategic implementation considerations for industrial recycling operations.
