UC Berkeley Scientist Wins Eni Award for Plastic Recycling

UC Berkeley chemist John Hartwig has received the 2026 Eni Award for developing catalytic technology that breaks down polyethylene and polypropylene into reusable chemical building blocks. The research could support higher-quality plastics recycling and reduce reliance on virgin petroleum-based feedstocks.

Summary

UC Berkeley Professor Wins Prestigious Eni Award
Professor John Hartwig of the University of California, Berkeley, received the Advanced Environmental Solutions Award at the Eni Awards ceremony in Rome. The recognition honours his innovative research into chemical recycling technologies that could improve the quality and sustainability of plastic recycling.
Innovative Chemical Process Enables High-Quality Plastic Recycling
Hartwig's research uses specialized chemical catalysts to break down complex polymer chains into reusable building blocks known as monomers. These recovered materials can be used as feedstock to manufacture new plastics with properties comparable to virgin materials, overcoming a major limitation of conventional mechanical recycling.
Technology Targets Two Major Plastic Polymers
The process focuses on polyethylene and polypropylene, which together account for approximately half of global plastic production. The polypropylene conversion process can recover propylene equivalent to roughly two-thirds of the original material, potentially reducing plastic waste and dependence on petroleum-derived raw materials.

UC Berkeley Scientist Wins Eni Award for Advanced Plastic Recycling Technology

UC Berkeley chemist John Hartwig has received the 2026 Eni Award for developing a catalytic process that converts used polyethylene and polypropylene into chemical building blocks for manufacturing high-quality plastics.

Key Points

UC Berkeley professor John Hartwig received the 2026 Eni Advanced Environmental Solutions Award.
The catalytic process targets polyethylene and polypropylene waste.
The technology aims to recover chemical building blocks for producing new plastics without sacrificing material quality.
Hartwig reported propylene recovery equivalent to roughly two-thirds of the original polypropylene material.

MONTREAL (Scrap Monster): University of California, Berkeley professor John Hartwig has received the 2026 Eni Advanced Environmental Solutions Award for developing a chemical recycling process designed to recover valuable materials from used plastics, including polyethylene and polypropylene.

Hartwig received the award at a ceremony held October 29 at the Quirinal Palace in Rome. Established by Italian energy company Eni, the award recognizes scientific contributions to environmental sustainability.

Catalytic Process Targets Plastic Recycling Limitations

The research addresses a major limitation of conventional plastic recycling. Mechanical recycling generally involves melting and reshaping discarded plastics, a process that can degrade polymer quality and limit the material's suitability for higher-value applications.

Hartwig's approach instead uses specialized chemical catalysts to break down polymer chains into reusable chemical building blocks, including monomers. These materials can then serve as feedstock for manufacturing new plastics with properties comparable to virgin materials.

ScrapMonster Edge: From Plastic Waste to Chemical Feedstock

The opportunity extends beyond diverting plastics from landfills. Hartwig's catalytic technology could allow recyclers to recover higher-value chemical feedstocks from polyethylene and polypropylene, rather than relying solely on mechanical recycling that can reduce material quality.

Industry takeaway: Commercial viability remains the key question. Catalyst durability, tolerance to contaminated waste streams and continuous processing must still be demonstrated at industrial scale before the technology can offer a practical alternative for plastics processors.

Polyethylene and Polypropylene Offer Major Recycling Potential

The technology focuses on polyethylene and polypropylene, two widely used polymers that together account for approximately half of global plastic production, according to the original report.

Hartwig reported that the polypropylene conversion process can recover propylene equivalent to roughly two-thirds of the original material.

The research offers a potential route to reducing plastic waste sent to landfills and incinerators while limiting dependence on petroleum-derived feedstocks for new plastic production.
