What are plastics?<\/span><\/b>\u00a0<\/span><\/h4>

Plastics are synthetic materials made from polymers, which are long chains of molecules that are found in nature or developed in laboratories. They are lightweight, durable and versatile, making them an essential part of daily life. From packaging to construction, plastics are everywhere.<\/span>\u00a0<\/span><\/p>

Why are plastics important?<\/span><\/b>\u00a0<\/span><\/h4>

Plastics have revolutionized industries by providing affordable alternatives to traditional materials like wood and metal. They help reduce the weight of cars, improve medical devices and even make their way into our homes in the form of appliances. Plastics also help to preserve trees and natural resources by replacing paper products and packaging.\u00a0\u00a0<\/span>\u00a0<\/span><\/p>

The environmental impact of unrecycled plastics.<\/span><\/b>\u00a0<\/span><\/h4>

While plastics offer numerous benefits, their environmental impact is significant. Plastics can take hundreds of years to decompose if they end up in landfills or oceans, which can harm wildlife and our planet. By recycling plastics instead, we can all make a difference.\u00a0<\/span>\u00a0<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Common uses of PET<\/span><\/b>\u00a0<\/span><\/p>

PET is commonly used in beverage bottles and food containers. It’s lightweight and shatter-resistant, making it a popular choice for packaging.<\/span>\u00a0<\/span><\/p>

Identifying PET<\/span><\/b>\u00a0<\/span><\/p>

PET items are usually transparent and have a recycling symbol with the <\/span>number 1<\/span>. When crushed, they produce a loud crackling noise, distinguishing them from other plastics.<\/span>\u00a0<\/span><\/p>

Recycling PET\u00a0<\/span><\/b>\u00a0<\/span><\/p>

In Canada, PET packaging and containers are accepted for recycling. Once recycled, it can be transformed into new bottles, clothing fibres and packaging materials. This makes it one of the most recycled plastics.<\/span>\u00a0<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
