How to Recycle Cardboard: The Process of Recycling Cardboards in Melbourne
What is Cardboard Recycling?
One of the most common waste materials produced in offices, restaurants and numerous other commercial businesses, cardboard remains highly recyclable and environmentally friendly. We are moving away from the use of plastic and towards paper-based materials for good reason! The best part of cardboard is that it’s sturdy, malleable and relatively inexpensive; it has a great number of applications and is easily reused or broken down at a recycling station. Let’s take a look at the process of cardboard recycling in Melbourne.
Process of Recycling Cardboard:
The process of cardboard recycling is easy and inexpensive. Firs, you have to collect and sort the cardboard and take it to a recycling facility. Collected cardboard then tore down into smaller parts to make a liquid-type paste, which is called Pulping. Created cardboard paste is then filtered to remove any foreign materials and reassembled for the final process. Here is the step by step process on how to recycle cardboard.
- Collecting & Sorting
Collecting and Sorting
As mentioned, cardboard can be and is frequently reused in households and in commercial settings. Old cardboard boxes can be used as a playhouse for children, storage or sending packages to name just a few. We’d highly recommend making every effort to use old cardboard material if you have a use for it.
However, there comes a time when it can no longer be used and needs to be disposed of, whether that be in a rubbish bin, skip bin or wherever else you may dispose of your trash. It is then collected and taken away to a recycling facility and sorted according to the type of cardboard.
Different types of cardboard are made up of slightly different materials, which means the process of treating and recycling them is different. Boxboard, for instance, is especially thin and is usually used for packaging, whereas other varieties such as corrugated boxes are much thicker and are often used to transport heavy items.
Nearly every material is recycled by breaking it down into smaller parts. In the case of cardboard, the idea is to create an almost liquid-type paste out of the material, which is then treated and made to solidify. To do so, cardboard is shredded down into small pieces of paper. In a process known as pulping, these pieces are combined with water and special chemicals, which are mixed around until the paste substance, or pulp is produced.
Foreign items, which can be especially small and hard to find, then need to be removed from the equation. To do this, the pulp is filtered and essentially cleaned. These items may include things like plastic, string, metal or organic materials. Many of these items are separated from the pulp with the use of a centrifuge, which spins the material around until foreign items float to the top or are pushed to the bottom.
The filtered material is combined with certain chemicals to prepare it for the final step of the process; drying and preparing for reuse. The pulp is placed on a heated, conveyor-belt surface where it sits to dry and moves through various machines to treat it. These machines will remove excess water and help form shape of the sheets of cardboard sheet, known as liner boards, will take on. I most cases, these sheets are glued together to create the finished product.
Cardboard recycling process generally takes place in a specialised recycling centre or a paper mill. It gives you a sense of how easily cardboard can be processed, broken down and created again for reuse. This is also a relatively inexpensive process.
