Plastic was never meant to become permanent—but neither was the way we chose to use it. In a world grappling with waste, emissions, and accountability, one scientist quietly began rewriting the chemistry of responsibility. Dr. Fanny Liao, EVP of Research and Development at Far Eastern New Century (FENC), one of the world’s leading polyester and PET manufacturers, is advancing visionary research in sustainable polyester/PET at a defining moment when the industry must answer to impact. At the rare intersection where chemistry, leadership, and ESG converge, she is redesigning materials at the molecular level to serve both progress and the planet.
Sustainability as Strategy, Not Slogan
In the evolving language of global business, sustainability is no longer an aspiration—it is a matter of accountability. At the heart of ESG—environmental responsibility, social stewardship, and governance integrity—sits a question industries can no longer defer: How do we grow without costing the planet its future?
For Dr. Fanny Liao, sustainability is not a trend to follow but a scientific, operational, and moral imperative to execute. As Executive Vice President of Research and Development at Far Eastern New Century (FENC), one of the world’s leading polyester and PET manufacturers, she stands at the intersection of chemistry and consequence, transforming one of the most widely used materials on earth into one of the most responsibly reimagined.
A Scientist Formed by Curiosity and Choice
Dr. Liao’s journey began with chemistry, but it was shaped by choice. She earned her bachelor’s degree from Fu-Jen Catholic University in Taiwan and later completed her Ph.D. at the State University of New York at Stony Brook. While pursuing her doctorate, she also undertook a patent law internship at a New York patent law firm—an early signal of her instinct to bridge science with real-world application and protection of innovation.
After postdoctoral research, she faced a defining crossroads: academia or industry. Despite receiving an offer for a professorship, Dr. Liao chose the chemical industry, drawn by the scale, immediacy, and impact it could offer. She began her professional career in the petrochemical industries, working across commodity and specialty chemicals, grounding her scientific expertise in industrial reality.
Enter Far Eastern: Scale Meets Purpose
Her trajectory deepened when she joined the Far Eastern Group (FEG), a global conglomerate whose subsidiary, Far Eastern New Century, produces millions of tons of polyester and PET annually. Within this ecosystem, Dr. Liao became involved in chemicals related to polyester feedstock, placing her at the core of materials that shape everyday life—from packaging to textiles.
Over 28 years at FEG, her experience expanded across an extraordinary spectrum: specialty chemical project management, medical device research and manufacturing, PET bottle recycling operations, biotechnology venture capital investments in the United States, joint venture management in Canada, brewery construction and operations in China, and billion-dollar mergers and acquisitions in the U.S. Along the way, she built a reputation not only as a scientist, but as a negotiator and business leader adept at navigating complex global partnerships.
Today, she carries dual leadership roles—as President of Oriental Resources Development Ltd., overseeing medical device manufacturing, and as EVP of R&D at FENC, managing research facilities across Taiwan, Shanghai, and the United States, with a team of more than 150 professionals dedicated to sustainable polyester/PET and next-generation materials.
Turning Losses into Leadership Lessons
In 2008, Dr. Liao entered the medical device operations at a time of challenge. The business unit was operating at a loss. Under her leadership, it was not only turned around—it became the highest-profit-margin business unit within the Group for more than a decade.
At the same time, she took charge of the PET bottle recycling operation, which had suffered losses for ten years. Amid the global financial crisis, she reversed its fortunes within two years. That experience sharpened her realization: PET recycling was not merely a business challenge—it was an environmental responsibility. From that moment, sustainability moved from concept to conviction.
Bio-Based PET: Rethinking the Starting Point
Dr. Liao initiated FENC’s bio-based PET research using agricultural waste—rice straw and corn stover—rather than edible sugar sources. This distinction mattered. Sustainability, in her view, must not compete with food security.
Through leadership and partnership with U.S.-based Virent, FENC produced the world’s first batch of 100% bio-based PET bottles for Coca-Cola, showcased at the Milan Expo in 2015. A year later, the collaboration yielded the world’s first 100% bio-based polyester shirt, earning the 2016 European Bioplastic Award. These milestones marked her first decisive step toward PET sustainability—and set global benchmarks.
Recycling Beyond Transparency: A Chemical Breakthrough
For decades, only transparent PET bottles were recycled into polyester. FENC pioneered bottle-to-bottle recycling in the 2010s, but Dr. Liao pushed further. Colored bottles, previously unrecyclable through mechanical processes, became her next frontier.
Her team developed chemical recycling through depolymerization, breaking PET down to raw materials and re-polymerizing it into virgin-quality bottles. The world’s first chemically recycled colored PET bottles were commercially launched for Coca-Cola beverages in Japan—another global first.
She then addressed what others ignored: colorful PET labels, typically incinerated and responsible for additional CO₂ emissions. Partnering with Coca-Cola Japan, her team achieved the world’s first label-to-label recycling via chemical processes, closing another loop in PET packaging.
From Bottles to Fashion: Textile-to-Textile Recycling
With packaging solutions advancing, Dr. Liao turned to textiles, which account for roughly 60% of PET is used for textile applications, and 40% is used for packaging worldwide. Textile waste posed a greater challenge—mixed fibers, dyes, and materials demanded chemical recycling rather than mechanical solutions.
After years of research and multi-step development, FENC unveiled the world’s first polyester shirt made entirely through textile-to-textile recycling at the Taiwan Innovation Textile Application Show (TITAS). The innovation is now scaling toward ten-thousand-ton commercial capacity—signaling a new era for circular fashion.
Science Fiction, Made Commercial
Could polyester clothing be made from steel mill waste gas? For Dr. Liao, this was not science fiction—it was chemistry with purpose.
Through a partnership with U.S. biotechnology company LanzaTech, FENC commercialized polyester derived from captured steel mill waste gas, supplying global fashion brands including Zara, Lululemon, and H&M. By capturing and fixing carbon emissions into wearable materials, the innovation dramatically reduced polyester’s carbon footprint and opened a new chapter in sustainable fashion.
Biological Recycling and Enzymatic Futures
Mechanical and chemical recycling were not endpoints. Dr. Liao expanded sustainability further through collaboration with French biotech company Carbios, whose enzymes enable the biological recycling of polyester. Together, they achieved another world first: new polyester shirts made through the biological recycling of waste polyester.
Her vision continued into thermoplastic polyester elastomers (TPEE). Through chemical transformation, waste PET rigid bottles were converted into soft TPEE shoe midsoles. The world’s first recycled TPEE midsole was launched with French brand Salomon for Solamphibian shoes—offering a sustainable alternative to high-carbon, hard-to-recycle TPU and EVA materials.
Carbon Dioxide as a Resource, Not a Liability
Perhaps most transformative is Dr. Liao’s work using CO₂ itself as a feedstock. Polyurethane, among the highest carbon-footprint plastics, traditionally relies on toxic isocyanates derived from phosgene. By replacing isocyanates with captured CO₂, her team developed non-isocyanate polyurethane (NIPU), significantly reducing emissions and toxicity.
This breakthrough earned the 2nd Prize at Germany’s 2025 Best CO₂ Utility Award—global recognition of chemistry applied with conscience.
Leading the Way Forward
Dr. Fanny Liao’s legacy is defined by execution as much as vision. From 100% bio-based PET and waste-gas-derived polyester to chemical and biological recycling, recycled TPEE, and CO₂-based NIPU, she has authored multiple world-firsts in sustainable plastics.
She is not merely advancing materials science—she is redefining what responsible industrial leadership looks like in the ESG era. With her team and global partners, Dr. Liao continues to lead the way toward a greener, more accountable future—one molecule, one breakthrough, and one decision at a time.
