Why Recycle Plastic? Stages of Plastic Recycling Process.


Why Plastic Recycling:

On average a single family discards an average 500 plastic bottles each year, and a large percentage end up in landfill sites. Most plastic bottles are produced using polyethylene terephthalate (PET) or high-density polyethylene (HDPE), both of which are degradable plastics. This implies when they are exposed to enough light, oxygen, warm or mechanical stress, they can degenerate into water, carbon dioxide, biomass and trace elements. However, this procedure can take centuries, amid which time the plastic is consuming landfill space and can be possibly destructive to wildlife, particularly if it ends up in the sea. The best solution for disposing of plastic bottles is to recycle them to generate, among other things, brand new bottles.

This in addition to diminishing the amount of waste going to landfill, also helps conserve the non-renewable energy sources needed to make bottles and would in turn lessen emission of green house gases. In fact, recycling one plastic bottle can sufficiently spare energy to run a 60-watt light for three hours.

Recycled plastic bottles can be transformed into a wide range of valuable things. For instance, the drops produced using liquefying plastic can be spun into a fine polyester fiber, which can be utilized which can be used to make fleece clothing, carpets and duvet filling.  The sturdiness of recycled plastic makes it perfect for use in seepage funnels, platform sheets and fences, and it’s a cheap material for making road furniture, signs and containers. The stationery in your geometry boxy could be produced using recycled bottles as well, as the plastic pieces can be reshaped into rulers, pencil sharpeners and different things.

Stages of Plastic Recycling Process:

  1. Collection:

The discarded plastic bottles are gathered and taken to a recycling unit for sorting. If these have been officially isolated before the plastic bottles they can be sent straight to a recycling plant.

  1. Separating:

The recycling is hand checked to remove any non-recyclable material. A ‘trommel’ – a vast punctured turning drum – then isolates plastic containers and jars.

  1. Sorting:

The bottles are then cleaned and sorted by type and colour using infrared beams.. The infrared light is reflected off of the plastics in various ways, enabling a sensor to distinguish which is which. Precision jets of air then separate the different types.

  1. Shredding and melting:

Next they are destroyed by a machine and washed again to expel any pollutants, for example, leftovers of paper marks or the original substance. They may also be decontaminated further using a chemical solution. The shreds of plastic are then dried and softened down.

  1. Flaking

The softened plastic is transformed into drops or pellets as it cools. These would then be able to be softened down and used to make new items, for example, new plastic bottles.
