SEATTLE (Scrap Monster): University of California, Berkeley professor John Hartwig has received the prestigious Eni Award for developing an innovative chemical process that could aid high-quality recycling of used plastics, including polyethylene and polypropylene.
Hartwig received the Advanced Environmental Solutions Award at a ceremony held at Rome's Quirinal Palace. The award, established by Italian energy company Eni, recognizes scientific contributions supporting environmental sustainability.

The research addresses a major limitation of conventional plastic recycling. Existing mechanical recycling methods typically involve melting and reshaping discarded plastics, which can degrade polymer chains and reduce material quality. As a result, recycled plastics could be used only in lower-value industrial products.
Hartwig's approach uses specialized chemical catalysts to break down complex polymer chains into reusable building blocks called monomers. These materials can subsequently serve as feedstock for manufacturing new plastics with properties comparable to virgin materials.
The technology targets polyethylene and polypropylene- two polymers that collectively account for approximately half of global plastic production. The polypropylene conversion process can recover propylene equivalent to roughly two-thirds of the original material, Hartwig claimed.
The breakthrough could help reduce plastic waste sent to landfills or incinerators while reducing dependence on petroleum-derived raw materials.

Frequently Asked Questions
- Who received the Eni Award for innovative plastic recycling research?
John Hartwig, a professor at the University of California, Berkeley, received the Advanced Environmental Solutions Award. The recognition was presented at a ceremony held at Rome's Quirinal Palace for his research into innovative chemical processes that could improve plastic recycling.
- How does John Hartwig's chemical recycling technology work?
The technology employs specialized chemical catalysts to break down complex plastic polymer chains into reusable building blocks called monomers. These recovered materials can subsequently be used as feedstock to manufacture new plastics with properties comparable to virgin materials.
- How could this breakthrough benefit the global plastics recycling industry?
The technology could improve the quality of recycled plastics by recovering their constituent chemical building blocks rather than simply melting and reshaping discarded materials. It could help reduce plastic waste sent to landfills and incinerators while lowering reliance on petroleum-derived feedstock for manufacturing new plastics.
