Vietnam's recycling industry is growing at 12% annually, and Vietnam Eco Machinery (VEM) is leading the charge to localize equipment production. Founded in Ho Chi Minh City in 2015, VEM started as a distributor of Chinese shredders but quickly pivoted to manufacturing its own, aiming to reduce reliance on imports. Today, its 4-shaft shredders are 80% locally made, from steel frames to electrical components, making them affordable and easy to repair. The VEM-4S-800 is their most popular model, designed for small to mid-sized facilities processing plastic waste, (scrap refrigerators and AC units), and low-grade metal. With a capacity of 400–800 kg/hour and a price point under $50,000, it's become a staple in Vietnam's burgeoning informal recycling sector.

VEM's success stems from its grassroots approach: the company works closely with local recyclers to understand their needs, often modifying designs based on feedback. For example, many Vietnamese recyclers process waste in open-air yards, so VEM added weatherproof enclosures to its shredders. They also offer mobile units mounted on trucks, allowing clients to bring shredding services directly to waste collection points. While still expanding its product line, VEM has plans to launch a (lithium battery breaking and separating equipment) in 2026, capitalizing on Vietnam's growing EV battery recycling market.

Rounding out our list is Dragon Recycling Equipment, a Beijing-based heavyweight known for its large-scale, turnkey recycling solutions.
