From Plastic Bottles to Backpacks: A Win-Win for the Environment and Textile Industry
Dec 10, 2024
White pollution has become a concern for all industries, as it affects everyone's living environment. Plastic bottles have been used in various aspects of life and production since their inception, from ubiquitous water bottles to various containers used in chemical and medical industries. It can be affirmed that human life cannot be separated from plastic bottles. However, the molecular structure of plastic bottles is very stable, which means that they typically take 500-1000 years to fully degrade in the natural environment. Therefore, the harm of discarded plastic bottles to the environment is enormous.
The Origin of Plastic Bottles
In 1941, British scientists invented polyethylene terephthalate (PET), which is now the main material for plastic bottles. They discovered that PET is a lightweight and sturdy material. However, no one thought of using this new material for producing packaging containers until 1973 when an American scientist (Nathaniel Wyeth) invented the technology to make PET bottles and applied for a patent. These bottles are durable, transparent, lightweight, and cost much less than glass. Soon, this type of plastic bottle replaced the glass bottles of that time.
The Harm of Plastic Bottles
Not long after the widespread use of plastic bottles, scientists noticed that plastic bottles began to accumulate in large quantities, especially in the oceans where a large number of plastic bottles were found. In 1980, scientists began to study the decomposition characteristics of plastic bottles, but they found that this material is difficult to decompose in the natural environment and usually takes hundreds of years to decompose in the natural environment. This made them start to recognize the harm of plastic bottles.
In 1997, American marine researcher Charles Moore discovered the Great Pacific Garbage Patch - a massive pollution area mainly composed of plastic waste, with an astonishing area of 16 million square kilometers, almost the size of the entire continent of Africa! This led many countries to establish plastic recycling systems at that time.
The Birth of RPET
In 1993, Patagonia in the United States launched products made from recycled polyester fibers (RPET), pioneering the transformation from plastic recycling to textile production.
The Process of Making RPET
The main steps in recycling PET into RPET include collection, cleaning, crushing, melting, spinning, and weaving. In this process, other impurities in the plastic are separated, and dirt, glue, oil, and other stains on the surface are cleaned off. Modern recycling technology has been continuously optimized to further improve the strength of RPET, and now the strength of RPET material is almost comparable to PET. RPET is now widely used in packaging and textile industries.
Synberry's Sustainable Commitment
We have always adhered to the principle of sustainable development, and we are delighted to see more sustainable materials on the market and incorporate them into our products. We believe that the future of the backpack industry will be more environmentally friendly and green.
