Background: Ms. Linh, a 32-year-old university graduate with a major in environmental engineering, established her plastic recycling company in District 4, Ho Chi Minh City (HCMC) in 2022. Motivated by Vietnam’s National Plastic Waste Management Strategy 2021-2030— which aims to achieve 50% plastic recycling by 2030—her medium-sized factory is strategically located near Saigon Port, Vietnam’s busiest seaport. The facility processes 4 tons of PET bottle waste daily, addressing a critical need: HCMC generates over 8,000 tons of plastic waste per day, with PET bottles accounting for 28% of the total, primarily from local supermarkets, convenience stores, and port cargo packaging. Ms. Linh’s core goal is to convert waste into valuable resources while mitigating plastic pollution in the city’s waterways, but her outdated Plastic granulator failed to produce the high-purity granules required by HCMC’s leading packaging manufacturers.
Plastic granulator
The Challenge
Ms. Linh encountered three critical pain points that hindered her business growth and profitability. First, her obsolete industrial Plastic granulator featured a single-layer filter system, resulting in 11% of PET granules containing impurities (such as paper labels and plastic fragments). This made the granules unmarketable to high-end packaging companies in HCMC, limiting her revenue potential. Second, the machine’s screw had a low L/D ratio of 1:27, leading to incomplete melting and 13% of granules with air bubbles—this reduced the material’s tensile strength and market value significantly. Third, HCMC’s hot and humid climate (with an average humidity of 80%) caused PET bottle waste to have a moisture content of up to 15%, which the old granulator could not handle. This led to frequent equipment jams and 9 hours of unplanned downtime per month. Ms. Linh tested PET bottle Plastic granulator models from two local suppliers but found they lacked a pre-drying system and reliable after-sales support, with spare parts taking 10 days to arrive—further disrupting her operations.
The Solution
We customized a TL-150 Plastic granulator specifically tailored to HCMC’s PET bottle waste characteristics, humid climate, and Ms. Linh’s strict quality requirements. The professional configuration includes the following key features:
- A screw with an L/D ratio of 1:32, ensuring full melting and uniform mixing of PET bottle waste to completely eliminate air bubbles in the final granules.
- A hydraulic screen changer equipped with a 120-mesh filter, removing 99.9% of impurities and ensuring granule purity reaches 99.6%—fully meeting the high standards of HCMC’s premium packaging manufacturers.
- An integrated pre-drying system with a dehumidifier, reducing the moisture content of PET bottle waste from 15% to below 2% to prevent jams and ensure consistent, stable operation.
- A PLC full-automatic control system, reducing manual operation from 4 workers to 1 and cutting labor costs by 75%—a critical advantage amid HCMC’s rising minimum wage (VND 4,680,000/month in 2026).
- Local after-sales support in HCMC, with spare parts stored in our District 7 warehouse and 24/7 technical assistance, ensuring downtime is reduced to less than 1 hour per month.
Our pre-sales team conducted on-site inspections of Ms. Linh’s factory, provided a detailed feasibility report, and trained her 3 staff members on equipment operation and maintenance. Additionally, we assisted her in applying for Vietnam’s green business subsidy, which covered 12% of the equipment cost—further reducing her initial investment burden.

The Results
After 3 months of continuous operation, the customized Plastic granulator delivered remarkable, measurable outcomes for Ms. Linh’s business: 1. Production capacity increased from 280 kg/h to 620 kg/h, boosting daily output from 4 tons to 9.9 tons (rounded to 10 tons). 2. Granule purity reached 99.6%, enabling her to sell the recycled material at VND 11,000/kg (up from VND 7,000/kg), increasing monthly profit by VND 1,200,000,000. 3. Downtime was reduced from 9 hours to 25 minutes per month, adding 105 production hours annually. 4. The pre-drying system eliminated moisture-related jams, cutting maintenance costs by 62% (saving VND 186,000,000 per year). 5. She secured a long-term supply contract with a HCMC-based packaging company, ensuring stable sales and business growth. “ThisPlastic granulator is high-purity, reliable, and tailored to HCMC’s climate. It turned my struggling business into a profitable venture and helped me contribute to the city’s plastic waste reduction goals,” said Ms. Linh.
