HDPE (high-density polyethylene) sundry bottles generally refer to HDPE bottles that are not food packaging, such as detergent bottles, shampoo bottles, shower gel bottles, motor oil bottles, and pesticide bottles (which require special handling). Compared to food-grade HDPE bottles (such as milk bottles), these bottles contain more complex contaminants and are more challenging to clean.

Our hard plastics/engineering plastics recycling solutions target hard plastics such as plastic pipes, appliance casings, automotive parts, injection molding scraps, and ABS/PS/PC. They feature powerful crushing, fine sorting, and dust-free processing. Core equipment includes heavy-duty crushers, single-shaft shredders, electrostatic separators, and modified granulation lines, solving the problems of difficult crushing, low sorting accuracy, and poor performance of recycled materials in hard plastics.

Success Stories

A recycling center in a county in Central China handles HDPE waste from townships. Its existing equipment only achieves 85% purity after cleaning, resulting in low raw material prices and narrow profit margins. The client wants to increase output and improve the quality of the sheets to increase profits.

Case Study: 2000kg/h High-Precision HDPE Washing Line for Licensed Recycler in Malaysia

1. Project Overview Location: Malaysia Date: August 22, 2025 Capacity: 2000kg/h (2 Tons per Batch) Material: Imported & Local HDPE Rigid Plastics Application: Premium Flakes for Injection Molding & Industrial Piping 2. The Challenge The client, a licensed SME recycler in Malaysia, faced a dual challenge: Strict Compliance: Malaysia’s environmental policies require imported plastic waste to be processed with high efficiency and zero pollution leakage. Complex Feedstock: The mixed raw materials (local and imported) contained metal contaminants and non-plastic debris, requiring high-precision sorting to meet the quality standards of downstream pipe manufacturers. Consistency: They needed to balance high cleanliness with a stable 2-ton-per-hour throughput to maintain their manufacturing license quotas. 3. Ruili Machinery’s Solution We designed a comprehensive, multi-stage cleaning and sorting plant focused on purity and automated separation: Advanced Pre-treatment: Integrated a Magnetic Separator and Eddy Current Separator to automatically remove ferrous and non-ferrous metals, ensuring the safety of downstream blades and the purity of the final flakes. Professional Cleansing: Utilized a Constant Temperature Hot Alkaline Solution Tank combined with high-speed friction cleaners to strip away stubborn labels, industrial oils, and glue. Density Separation: A precision flotation/sinking tank was used to isolate clean HDPE from other floating or sinking

Case Study: High-Capacity 3000kg/h HDPE Rigid Plastic Washing Line for Grade-A Recycled Flakes

1. Project Overview Location: Central China Date: December 12, 2024 Equipment: 3000kg/h High-Efficiency HDPE Rigid Plastic Washing Line Input Material: Mixed HDPE waste from township collection centers Final Application: High-Purity Sheets for Melt Granulation 2. The Challenge A regional recycling center was struggling with outdated equipment that could only achieve 85% purity. This led to: Low Market Value: The contaminated flakes sold for much lower prices. Narrow Profit Margins: High processing costs combined with low-quality output made the business unsustainable. Scaling Bottleneck: They needed a much higher throughput (3 tons per hour) to handle the growing volume of local HDPE waste. 3. Ruili Machinery’s Solution We implemented a state-of-the-art washing technology tailored for mixed rigid plastics, utilizing a 5-step optimized process: Pre-treatment: Automatic sorting and size reduction to prepare the material. Hot Alkaline Washing: Specialized high-temperature alkaline solution to dissolve stubborn organic fats and oils. High-Speed Friction Cleaning: Mechanically removing labels, glue, and surface contaminants. Flotation & Sedimentation: Advanced density separation to ensure 100% removal of non-HDPE sinkable impurities. Centrifugal Dehydration & Drying: Ensuring the final product is dry and ready for immediate extrusion. 4. Results & Performance After the implementation of the Ruili 3000kg/h line, the results were transformative:
