Mitigation Product

FENC continues to devote resources to the research and development of sustainable green products, providing green solutions that offer recycling and reduction of energy and resource consumption, thereby decreasing GHG emission and mitigating climate change.

►Mitigation Product Flow

PET is made of 70% PTA and 30% MEG. With years of research and development, Bio-MEG produced with biomass is starting to gain economic values. The source of biomass materials is non-food plant, which doesn’t take up shares of food sources. The use of biomass also reduces dependence on fossil fuel and lowers GHG emission.
As the world leader in Bio-PET production, FENC builds upon 50 years of experience in polymerization and successfully created the world’s first 100% Bio-PET bottles and shirts.

Invention of the First 100% Bio-based PET Bottle in the World

100% Bio-polyester shirt

FENC stays ahead of its industry peers, becoming the first in the world to introduce 3rd generation Biomass High Tenacity Yarn (bHTY). The 2nd generation bHTY is the polymer of PTA and Bio MEG, which is distilled from fermented sugar cane instead of petroleum. The 3rd generation bHTY utilizes carbon capture technology, capturing exhaust from the steel refinery, which is then fermented into alcohol and chemically transformed into ethylene glycol. Such technology minimizes the consumption of edible plants while reducing carbon emissions, which is a significant contribution to circular economy and pollution reduction.

PEF (polyethylene furanoate) is a polymer of plant-derived 2,5-Furandicarboxylic Acid and MEG. PEF possesses traits that are similar to those of PET, and PEF has even higher gas barrier properties. It is regarded as a suitable material for soda and beer bottles, and one of the key biomass packaging materials internationally.

The European Union has approved the recycling of Bio-PEF with PET bottles when it’s under 2%. Comparing to PET, the Bio-PEF production process consumes 65% less energy and emits 70% less CO2, giving this emerging biomass material carbon reducing quality.

The R&D Center joined forces with R&D departments and production sites. In 2019, they successfully developed the first Bio-PEF soda and beer bottles in Asia with gas-barrier property. One of the major breakthroughs during the process is the effective use of FENC’s existing PET production facility.

♦FENC® Recycled PET

With recycled PET bottles as material, production process entails crushing, cleaning, decomposition, polymerization and granulation. Recycled PET helps us reduce reliance on fossil fuels and waste of resources. It also promotes recycling and reuse of resources.

Implement circular economy – FENC giving new value to recycled PET bottle (Chinese)

♦Recycled Nylon 66 Filament
To respond to the trend of sustainable development as well as guidelines on energy conservation and carbon reduction, FEFC had been developing recycled nylon 66 filament since 2014. Spinning waste is recycled and reused through the process of collecting, melting, filtrating, re-pelletizing and re-spinning. Bypassing the polymerization process, this recycling and reuse process reduces energy consumption and CO2 emission by approximately 70%, hence benefiting the environment by facilitating energy conservation and carbon reduction.

♦Fast Reheat and Energy-saving PET Resins
FIR absorber is added during polymerization to produce the energy saving PET resin. This process enables the material to effectively absorb FIR thermal energy from the quartz heating lamp during blow molding for customers, and enhances efficiency for them by 20% to 30%.

Lightweight Preforms
Modifications made to the production process and materials increased stability of the blow molding process and greatly reduced the thickness of PET bottles. These characteristics lower material consumption, and reduce product weight by 10% to 20%, depending on the bottle size. During the product life cycle, delivery, for instance, consumption of other resources and carbon footprint are also reduced during transportation, resulting in more environmental benefits.

FENC® EZ Dyed CD Filament
EZ dyeing is a low temperature dyeing process without compromising the vibrant colors. This filament is ideal for blending with heat sensitive materials such as cotton, wool and nylon.

FENC® Dope Dyed Filament
During spinning POY, different color master batch is added. Making fabrics with dope dyed filament bypasses the dyeing process, which saves on dyeing agent, reduces the need for wastewater treatment, and prevents toxic substance. Such process also greatly reduces water consumption, energy waste, and CO2 emission. Dope dyed filament is the latest generation of environmental friendly and energy saving product, providing vibrant colors with better fastness to sunlight and washing。

Polyester products mainly include PET and fiber. PET products include PET bottles and packaging materials, which can be recycled and remanufactured into new polyester products, and FENC is the world leader of this technology. The main applications for polyester fiber are textiles such as apparel and interior textile. Different fibers are blended together during production. The complex composition adds to the difficulty of recycling.

In light of the fact that textile waste is under increasing public scrutiny, FENC launched the TopGreen ChemCycle Process development project. The goal is to develop chemical recycling and treatment technology for textile waste to address the current technological limitation of recycling only singular type of polyester textile. The goal is to turn textile waste into high-value functional textile, fulfilling the dream of circular economy using Textile to Textile (T2T).

This technology has received funding from the 2018 Taiwan Industry Innovation Platform Program (TIIP) from Industrial Development Bureau of MOEA. In addition to enhancing the core technology, FENC integrates related industries across several fields, including optical recognition, wastewater recycle and waste treatment. The company also built pilot plant to evaluate the feasibility of mass production.

FENC® rTex

FENC combines its unrivaled polymerization technology with recycling and reuse, turning PET bottles from ocean waste into eco-friendly yarn. The Company is currently the only supplier of this eco-friendly yarn with which adidas and Parley for the Oceans collaborate. The product was introduced to the market in 2016 and very well received. adidas produced 17 million pairs of footwear with plastic ocean waste during 2017-2019. It is anticipated that 15-20 million pairs will be produced in 2020.

As of 2019, this project had helped reduce 2,810 metric tons of plastic ocean waste. The year 2018 brought another 1,600 metric tons in reduction. Through circular economy, this project successfully created buzz and raised awareness among the public on protecting marine habitat. Applications include running shoes, sports jersey and apparel made of waterproof and breathable membrane. Mass production and shipment of the waterproof and breathable membrane began in 2018, and the product had been recognized as Top 10 in ISPO Munich 2019.

♦ Zero Solvent Coating & Lamination
FENC developed a coating and lamination process that requires zero solvent and completely water free. FENC Zero Solvent Coating & Lamination simplifies the coating & lamination process and is extremely durable against washes while maintaining consistent quality. Comparing to conventional solvent and water-based production, the Zero Solvent & Lamination process is water free and delivers energy conservation and carbon reduction with zero emission of harmful volatile organic compounds (VOC) and pollutants.

FENC®TopGreen® Coating & Lamination

♦ Water Free Dyeing
Demand for water is high during the dyeing process of textile products. The wastewater generated during this process is also another dilemma for the industry. Hence, FENC developed water free dyeing technology for polyester products. Water is replaced with CO2 supercritical fluid, which can be used repeatedly. The dye is infused into fabric or fiber in the hightemperature, high-pressure cycle with zero wastewater. The process is less time consuming, and conserves less energy and chemical required for dyeing, while maintaining product quality such as texture and elasticity.

FENC’s water free dyeing plant began operation in 2014. In 2018, the Company invested in a second water free dyeing system and eagerly developed additional applications of water free dyeing toward the more difficult nylon material. The two water free dyeing machines generate 80 metric tons/month in production capacity, conserving 8,000 metric tons of water per month, and reducing the consumption of dyeing and finishing agent by 16 metric tons per month.
