What is the 4 R‘s’ principle for waste reduction?
The 4 R ‘s’ principle for waste reduction is (Reuse, Recycle, Reduce, Refuse). The waste management systems break four parts, also known as the 4 R‘s. This process goes into a hierarchy that goes with the most preferable option and goes down the ladder. For example, don’t recycle plastic, when you can reuse it or even better by quitting it altogether.
Re-Buy or Purchase products with recycled content.
Can you find product options with recycled content? The determination of what can be recycled is based on technology and markets. Aluminum can be recycled into another aluminum can over and over.
There are well-established markets for aluminum and the process saves both raw materials and energy. A plastic bottle, however, is not recycled into another plastic bottle – it is shredded and re-purposed into other products like carpet, polar fleece, and plastic lumber.
The composition of various plastics determines what types of products they can be made into. Plastics are collected and sold on the open market to processors who make products with recycled content.
- Start getting metal coffee containers or straws instead of using single-use plastics.
- Use cloth bags or paper bags or eco-friendly bags instead of using plastic bags.
- Avoid using individually packed items.
- Avoid using disposable plates, cups, and utensils
Reduce: Part of throwing away less is using less and being more mindful as a consumer. So as being a consumer, you must always check before purchasing something, whether you actually need that product and how many users you can get out of it. For example:
1. If you need to buy clothes instead of purchasing cheap clothes you should purchase quality clothes, which can last longer than the cheaper once.
2. Take good care of your things so that they don’t wear off quickly and can be used more than their actual life.
3. Donate your old clothes instead of tossing them out.
Reuse: Before throwing away your trash, consider whether it can be reused for something else.
- Use chipped mug as a pen or a toothbrush holder
- Purchase reusable batteries
- Compost used tea leaves, tea bags & ground coffees and use them as fertilizer.
Recycle: After trying to implement the above 3 methods like Reuse, Refuse, Reduce you can choose to recycle principle in the waste management systems. For recycling, the trash one must segregate it before getting it at the recycling centers.
