PET is an abbreviation for polyethylene terephthalate
Polyethylene terephthalate is the most common thermoplastic polymer resin of the polyester family. It is used in fibres for clothing, containers for liquids and foods, thermoforming for manufacturing, and in combination with glass fibre for engineering resins. The biggest application of PET is in fibres (over 60%), with bottle production accounting for about 30% of global demand.
PET is widely used for carbonated beverage bottles due to its high strength and toughness, good abrasion and heat resistance, low moisture absorption, and excellent dimensional stability. It is also used to make artificial fibres for textiles, commonly found in clothing tags. These fibres have outstanding wear resistance and are very durable.
The recycling of PET waste is an important method for enhancing the environmental performance of the PET fashion and textile industries. Recycled PET (rPET) gives existing PET material a second life, producing new products like fibre for fabrics and food and beverage packaging. This reduces plastic waste and decreases the production of new PET, thereby reducing the extraction of natural resources, energy consumption, and toxic air pollution.
Mechanically recycled PET can be used in various applications in the textile industry, while chemically recycled PET can be used as feedstocks for polyurethane and unsaturated polyester resins.

PET is a recyclable plastic used for packaging and textiles
PET, or polyethylene terephthalate, is a clear, strong, and durable form of plastic. It is the most commonly used thermoplastic in the world and is used for a wide range of consumer products and textiles. In the context of textiles, PET is commonly referred to as polyester. It is widely used in the fashion industry, often blended with cotton, as a heat insulation layer.
PET is highly recyclable and can be recycled through mechanical and chemical methods. Mechanical recycling involves shredding used PET bottles into "flakes," melting them, and using the resulting microfilaments as the foundation for new products. Chemical recycling methods include glycolysis, methanolysis, and enzymatic recycling to recover monomers. Recycled PET (rPET) gives PET material a second life, producing new products like fibres for fabrics and food and beverage packaging.
The use of rPET is beneficial for the environment as it reduces plastic waste that would otherwise end up in landfills, decreases the need for new PET production, and reduces toxic air pollution caused by PET manufacturing. The fashion industry is the second-largest generator of plastic waste, largely due to the rise of fast fashion. Therefore, the use of recycled PET in textiles can significantly reduce the environmental impact of the industry.
PET is also commonly used for packaging, with about 56 million tons of PET produced annually for single-use packaging material. PET bottles account for a significant portion of global PET demand, with bottled water having the highest demand, followed by carbonated soft drinks and other drinks. Recycling PET bottles can also reduce waste and improve the environmental impact of the packaging industry.

Recycled PET reduces plastic waste and the need for new PET
PET, or polyethylene terephthalate, is a polymer substance made from the combination of ethylene glycol and terephthalic acid. It is a clear, strong, durable, lightweight, and versatile plastic material that is widely used for manufacturing soda bottles, water bottles, food packaging, and textiles.
The world consumption of PET packaging was expected to reach about 19.1 million tons by 2017, with a 5.2% increase per year between 2012 and 2017. PET is the most commonly used thermoplastic globally and is recyclable, but its production has a harmful impact on the environment as it generates toxic emissions and often ends up in landfills or oceans, causing harm to marine life.
This is where recycled PET (rPET) comes in. rPET is created by repurposing used PET materials, giving them a second life in new products. This reduces plastic waste and the need for new PET in several ways:
- Reducing Waste and Promoting a Circular Economy: rPET diverts PET bottles and containers from landfills and oceans, giving them another life in creating new products. This supports a circular economy where materials are continuously repurposed to limit and eliminate waste streams.
- Conserving Resources and Energy: rPET reduces the need for new raw materials, lowering the environmental impact of resource extraction and processing. It also reduces energy consumption as it requires less energy to recycle PET than to produce new PET from scratch.
- Lowering Carbon Emissions: By reducing the production of new PET, rPET helps decrease toxic air pollution and lower carbon emissions associated with PET manufacturing.
- Decreasing the Use of Crude Oil: PET forms a closed material cycle, reducing the utilisation of valuable resources like crude oil, which is used in the production of new plastics.
- Promoting Sustainability in Industries: The use of rPET in industries like fashion, interior design, and food packaging helps promote sustainability and reduce the environmental impact of these industries.

PET is the world's most common plastic, used in fast fashion
PET, or polyethylene terephthalate, is the world's most common plastic. It is a strong, stiff, synthetic material that is part of the thermoplastics family. It is widely used as it is durable, safe, and sustainable. PET is used in everything from bottles and food containers to personal care products. In the context of textiles, PET is commonly referred to as polyester. It is a popular choice for clothing due to its moisture barrier properties and wide applicability in bottling and packaging.
The fashion industry is now the second-largest generator of plastic waste, largely due to the growth of fast fashion. The traditional production cycle has increased from two cycles a year to around 50, and this trend is expected to continue, with global consumption of apparel projected to increase by 63% by 2030. The linear "take-make-waste" model of the industry means that only a small fraction of discarded clothing is recycled, resulting in most plastic textiles ending up as waste in landfills, incinerators, or the ocean.
The impact of plastic waste in the fashion industry is significant, with an estimated 35% of all microplastics in the ocean coming from the washing of synthetic textiles. These microplastics interfere with marine life and contaminate the food supply. However, there are efforts to increase the recycling of PET waste and enhance the environmental performance of the PET fashion and textile industries. Recycled PET (rPET) can be used to produce new products like fibre for fabrics, reducing the need for virgin plastic and decreasing the production of new PET.
Mechanically recycled PET can be used in various applications in the textile industry, and chemical recycling of PET can produce feedstocks for polyurethane and unsaturated polyester resins. Companies like Ambercycle are also developing innovative technologies to convert end-of-life clothing into new materials that can be recycled infinitely. These advancements in recycling technology offer a promising solution to the plastic waste crisis in the fashion industry.

Recycled PET thread is made from shredded, washed, and melted bottles
PET, or polyethylene terephthalate, is a clear, strong, durable, and recyclable plastic material widely used for manufacturing soda bottles, water bottles, and food packaging. It is also known as 'polyester' in the textile industry. PET is the most commonly used thermoplastic globally and is the preferred material for most consumer products and textiles.
The process of recycling PET bottles involves shredding, washing, and melting them down to create new products. The bottles are collected and washed in stages before being shredded into "flakes" and melted. This process yields microfilaments that serve as the foundation for sewing thread production. Recycled PET thread is produced using Micro Core technology, a unique microfilament-based spinning process. Approximately 1,000 meters of Sew-all rPET thread is produced from a single PET bottle, enough for ten individual spools.
RPET stands for recycled polyethylene terephthalate and involves repurposing existing PET material to produce new products like fiber for fabrics and food and beverage packaging. Recycled PET reduces plastic waste, decreases the need for new PET production from scratch, and lessens the extraction of natural resources and energy requirements. It also helps reduce toxic air pollution associated with PET production.
The fashion industry is the second-largest generator of plastic waste after the packaging industry, with the majority of plastic textiles ending up in landfills, incinerators, or the ocean. The use of recycled PET thread in the fashion industry can help mitigate these environmental impacts.
Additionally, companies like Ambercycle are converting end-of-life clothing into a new material that can be recycled infinitely. They extract PET from waste polyester clothing, creating a virgin-quality fiber called cycora™, which acts as a regenerated alternative to polyester.
