2. Understanding PET and its limitations

2.1. Global production and consumption

PET bottles appear in every corners of our life

Polyethylene Terephthalate (PET), a widely used plastic, undergoes substantial global production. Key manufacturing leaders, such as China, the U.S., and Europe, spearhead the production of this versatile material.
Recent years have observed a notable uptick in PET production, propelled by burgeoning markets. Industry trends are molded by factors like technological advancements and escalating demand.
Prominent industry players, including Indorama Ventures, Jiangsu Sanfangxiang, and Lotte Chemical, make substantial contributions to the worldwide production of PET. Their innovations and market influence underscore their pivotal roles in shaping the industry.
Globally, PET consumption displays diverse patterns, influenced by regional demands and specific industry requirements. A range of applications contributes to intricate trends in consumption.

2.2. Versatility in industries

In 1973, DuPont introduced PET plastic bottles as a cost-effective alternative to glass. Today, the global beverage industry trades over 500 billion PET bottles annually, almost a million per minute. The U.S. leads in PET consumption. 
Polyethylene Terephthalate (PET) stands as a versatile titan, weaving its utility across a spectrum of industries. From the packaging prowess in beverages to the textile terrain, PET’s adaptability is unmatched.
Beverage giants like Coca-Cola, PepsiCo, and Nestlé heavily bank on PET. Its unmatched clarity, strength, and recyclability position it as the preferred choice for preserving beverages and food.
In the textile sector, PET transforms into resilient polyester fibers, adorning our wardrobes with durable fabrics. The convergence of fashion and functionality is evident as PET threads weave into clothing and textiles.
Expanding its reach, PET finds applications across diverse sectors, including healthcare and automotive. Its sought-after attributes of malleability and durability make it an essential material in crafting a variety of necessities.

2.3. Environmental concerns

However, this reliance on PET drives fossil fuel extraction, petrochemical manufacturing, and plastics production, posing risks to human health, communities, and the climate throughout a bottle's lifecycle.
An alarming 8 million tons of plastic, including PET, inundate oceans annually. Insufficient recycling aggravates this crisis, imperiling marine life. PET production intensifies climate concerns, contributing to greenhouse gas emissions.
Every second witnesses a million PET bottles sold globally, but a mere 9% undergo recycling. Herein lies the predicament – a PET bottle takes a staggering 450 years to decompose. 
This stark reality spotlights the imperative shift to sustainable alternatives amid the burgeoning environmental crisis.

2.4. Impact on human health

While extensively utilized, concerns persist regarding the possible release of harmful substances from PET containers into their contents.
The focus on potential chemical migration is crucial. Over time, PET might release antimony, a heavy metal, and other compounds. Elevated temperatures, extended storage, and acidic contents amplify these migration risks.
Antimony, a naturally occurring element, is incorporated into PET production. Although low levels are considered acceptable, prolonged exposure or ingestion of elevated levels may pose health risks, prompting regulatory scrutiny.
The safety of PET relies on proper handling. Mitigating risks involves avoiding prolonged exposure to high temperatures and acidic substances. Adopting alternatives for specific applications where potential migration concerns emerge is a prudent approach.

3. The rise of PEF as a sustainable alternative

PEF compatibility with existing processing methods makes a seamless transition possible. The verdict on whether it's better or equal hinges on its enhanced eco-friendly features.

3.1. Properties and advantages of PEF

Consumer shift: embracing PEF’s biodegradable advantage

Polyethylene Furanoate (PEF) is sourced from renewable plant-based materials like sugarcane and cornstarch, emphasizing a commitment to sustainable resourcing. Its molecular structure creates a robust barrier against gas permeation, ensuring enhanced protection for packaged contents.
A key feature of PEF is its impressive biodegradability. Recognized as a carbon source by microorganisms, PEF undergoes natural decomposition. The time frame varies based on environmental conditions, with ideal composting allowing PEF to biodegrade within weeks to months.
PEF's production contributes to a lower carbon footprint compared to traditional plastics. Plant-based feedstocks absorb carbon dioxide, forming a closed-loop cycle that reduces overall environmental impact. PEF's recyclability enhances its eco-friendly profile, positioning it as a progressive material with sustainability at its core. As recycling infrastructure evolves, PEF holds promise in advancing circular economy practices.
