Vietnamese Students Develop Eco-Friendly Press Machine to Replace Plastic Products

A team of students from the University of Science and Technology in Đà Nẵng, Vietnam, has invented an innovative press machine that produces biodegradable plates and bowls from natural materials such as coconut husks, areca sheaths, banana leaves, lotus leaves, and almond tree leaves. This invention addresses pressing environmental concerns related to plastic pollution by providing sustainable alternatives to single-use plastic items.

Tackling Plastic Pollution with Sustainable Innovation

Plastic waste remains a significant environmental threat due to its persistence for decades or centuries, polluting soil, water, and air ecosystems. Motivated by rising consumer preference for green products, the student team—led by Mechanical Engineering student Lê Văn Tuấn and guided by Dr. Bùi Hệ Thống—designed the high-pressure press machine to form eco-friendly dishware. Key team members include Đặng Hữu Tài, Mai Xuân Sơn, Phan Tấn Sang, and Hồ Văn Lý.

Machine Design and Operation

The press machine combines several sophisticated components:

• Hydraulic force and control system to exert the necessary pressure for shaping and bonding materials.
• Heating system heats materials to 120-180°C for 60-90 seconds, aiding in molding and hardening.
• Pneumatic cleaning system uses high-pressure air blasts to remove dirt from raw materials.
• UV sterilisation unit ensures hygiene of the finished products.

Hydraulic technology was chosen after extensive experimentation to optimize force application and overcome friction challenges during pressing.

Benefits and Future Prospects

Using locally abundant and low-cost raw materials supports a circular economy by promoting recycling and sustainability. According to Dr. Thống, the machine can be adapted to manufacture various consumer products, expanding its usability across markets. Preliminary interest from farmers and gardeners highlights market potential.

The team plans to refine the machine further and offer it at an affordable price to Vietnamese consumers, aiming to scale distribution and contribute significantly to reducing plastic consumption nationwide.
