Explanation:

------------------------------

Recycling is the method of collecting and processing materials (that would otherwise be thrown away as rubbish) and transforming them into new products. Apart from the fact that recycling can benefit your home, it’s also advantageous to the environment.

Steps to Recycling Materials

Did you ever wonder what happens to the objects that you toss into recycling bins? Here’s a look at how glass, plastic, metal and paper are recycled. Recycling includes the three steps below, which create a continuous circle, which is represented by the renowned recycling symbol.

Glass

People have been using and reusing glass for thousands of years. Dating as far back as 3,000 years ago, Egyptians used glass to make jewellery, cups and other items. Made from sand, soda ash and limestone, glass is one of the easiest materials to recycle. So how does it work? Below are the stages of recycled glass production:

Glass :is first disposed through the door to door glass collection system or the bring-in site

Once collected, it is sorted

It’s then cleaned and crushed into what is called cullet

The cullet is brought to the manufacturing plant and mixed with more sand, soda ash and limestone

The mixture is heated in a furnace and turned into a liquid

This liquid is then poured into moulds and shaped into new glass products such as bottles, jars etc.

Plastic

Unlike glass, which is made entirely of natural elements, plastic is composed of man-made and raw materials, including petroleum and crude oil. So, here’s how plastic is recycled:

Plastic: is first thrown in the green bag or bring-in site

It’s then brought to the recycling plant where it is sorted into different plastic types

The plastic is then cut into small flakes which are separated in a flotation tankThey’re then dried and melted into a liquid

The liquid is cleaned even further, before coming out in long strands

The strands are chilled and chopped into capsules

They then make their way to manufacturers who use them to make new products

hope this helps you
