Polyethylene Terephthalate (PET) is a kind of plastic that is utilized to generate beverage bottles, packaging for food items, and it is also utilized in textiles such as clothing fabrics. It is estimated that in 2023, total imports of PET were of around 200 million pounds.
It can be recycled easily is the major reason behind the rapid adoption of PET in packaging industry. These recycled products can be used in manufacturing a wide range of products such as bags, clothes, and bottles. These are durable, lightweight and highly convenient to use. These are polyester plastic which is considered as safe material for the packaging of beverages. It has excellent water and gas barrier properties, unbreakability, transparency, UV resistance, light weight, and impact strength. These bottles are planned for one-use packaging and then these are disposed after use. To decrease the ecological influence from packaging waste and to push sustainability goal in plastic packaging, public recycling programs have been introduced to capture recyclable resource streams.
Government of several nation has taken initiatives to avoid the usage of plastic or introducing sustainable solutions for plastic packaging. In various countries there are strict guidelines for the usage of plastic packaging. The Union Ministry of Environment, Forest and Climate Change celebrated World Environment Day 2025 at Bharat Mandapam, under the slogan One Nation, One Mission: End Plastic Pollution.
UN Environment Programme has introduced four major goals to reduce plastic pollution:
The major steps taken by UN Environment Programme to enhance plastic packaging policies and targets by 2030:
Various advancement in recycling technology has introduced to encourage eco-friendly packaging. A group of researchers from IIT Bhilai recently introduced an eco-friendly technique for its recycling. It is used to recycle textiles, bottles, and packaging made up of PET. The research team includes Swarup Maity, Priyank Sinha, Dr. Sanjib Banerjee, and Sudipta Paul who were from the Department of Chemistry, has presented a nanotechnology-based method that proficiently depolymerizes PET into its core monomer which is bis(2-hydroxyethyl) terephthalate (BHET). By means of magnetically recyclable nano zero-valent iron (nZVI) as a catalyst, this process offers high yield and choosiness under mild conditions presenting the shortcomings of current recycling technology.
The increasing trend of westernization, expanding disposable earnings and shifting food designs of customers have raised the demand for packaged beverages, mainly in evolving countries such as China and India.
