How can we convert plastic waste into useful products?
Plastics have a unique combination of qualities that make them extremely useful. Polymers are lengthy chains of molecules which are made up of repeating monomers, and are commonly created from substances like petroleum. Its chemical structure may be tweaked to give it diverse properties, such as flexibility or hardness, transparency or opacity. They're long-lasting, sturdy, light, and water-resistant, as well as reasonably simple and affordable to make.
The majority of contemporary plastics are created from fossil fuels such as natural gas or petroleum, but as new technology develops, polymers derived from renewable resources such as maize or cotton are becoming more common. There are hundreds of patented plastics in use across a wide range of industries, each having its own set of characteristics that make it suitable for its intended use.
Our daily lives are surrounded by plastic!
Plastic is almost irreplaceable in many applications due to its, strength, low cost,light weight nature, and corrosion resistance. Plastic is most commonly used in packaging and construction components such as pipelines. Plastic is frequently used to prevent contamination and infection in the medical field. Pipettes,syringes, and gloves used in biomedical research and healthcare can never be reused. While the excessive use of plastic packaging is problematic, some sort of packaging is frequently required to preserve food sanitation or freshness, or to keep a product's integrity throughout transportation. Small or travel-size toiletries and personal hygiene items are sometimes considered wasteful, yet they are critical in providing cheap sanitation solutions for some of our most disadvantaged people.
Plastic garbage can get a second chance at life
Recycling waste plastic and reusing it in the production process minimises the requirement for virgin plastics and increases the economic worth of trash. Furniture, roads, packaging, and clothes are just a few of the goods that have lately been made from recycled plastic.
Plastics are divided into two categories: those that are readily recycled and those that are difficult to recycle. Plastics that are easily recyclable, such as PET in most bottles or HDPE in pipes and containers, may be cleaned, crushed into a powder, melted, and extruded into pellets that can be reheated and remoulded. Mechanical recycling is the term for this technique.
Chemical recycling can occasionally be used to recycle other difficult-to-recycle plastics, such as LDPE, polyethylene film, or contaminated plastics like unwashed food containers. This is a method of altering the polymer structure of a plastic and converting it into feedstock that may be used to substitute virgin ingredients in the manufacturing of plastics.
The world is beginning to see that it is past time to address the problem of plastic trash
This also necessitates dealing with the lack of adequate waste management systems. More than 30% of the world's population now lacks access to adequate trash collection and disposal.
There is no one-size-fits-all answer
It's not about switching from one single-use lifestyle to another; rather, it's about modifying our habits to strike a balance between convenience and sustainability, and encouraging business and governments to collaborate to get the greatest environmental results. Businesses ranging from hospitality to fashion are pledging to be more circular, redesigning packaging or using recycled materials; researchers are developing and improving new ways tosort, makeand recycle plastics. Moreover governments are re-evaluating their waste management systems to make recycling more accessible to their citizens.
Other solutions must be built and scaled at the same time
All of these activities contribute to reducing plastic waste in the environment and moving us toward a circular economy that unlocks the value of our garbage. It's a big endeavour, but it's one that can be accomplished with a lot of help.
