Importance of the 4Rs

Importance of 4Rs - Refuse, Reduce, Reuse, Recycle

By growing awareness and gaining an understanding of the environmental impacts we have on our planet, we can be better informed of where and how to act. A lack of awareness and responsibility has all added up to polluted land, sea, and air. From a lack of consideration of the environment in the way we manage waste to mass-producing throw-away items to keep up with demand. Thankfully things are changing and understanding the importance of the 4Rs can certainly help us inform our choices.

By increasing our sustainability in the home and better managing our waste we can all make a concerted difference5. Especially if we are to all play a role in helping keep our oceans free from plastic waste and reducing our consumption of needless items that can pollute our environment once disposed of.

If you are unfamiliar with the 4 Rs then they are:

  • Refuse
  • Reduce
  • Reuse
  • Recycle

The 4Rs make for a simple yet effective way to help us consider the items that we buy, use and dispose of. When we choose to stop and think about each of the 4Rs it helps us to consider a number of important aspects related to our consumption. From what we buy, to how we can reduce, to what can be reused, and how we eventually get rid of it.

If we are to make a difference to the environment then now is the time to identify the importance of the 4Rs.

Importance of the 4Rs - Why Do We Need To Be More Aware?

This is a prominent question that underpins the problems we are facing right now. Science tells us that we are prospectively heading towards a global sequence of events that will change the way in which we live. And impact many of the plant and animal species that we share the planet with.

Many of the products we produce cause greenhouse gases, which contribute to global warming. The way in which we needlessly throw things away impacts the oceans and wildlife. A lack of action has led us to where we are today.

If we do not radically transform how, what, and crucially how much we consume and mitigate the worst of our negative impacts on the planet we could see global temperatures increase by at least 2 degrees by 21004. In fact, 2016 was the warmest year on record.

Many are now starting to feel the resulting changes of a warming planet. From melting ice caps to more extreme weather. With this comes food shortages, water shortages, and sea levels rising by several feet.

Towns and villages will become submerged and populations could be wiped out. It is a very real problem that we need to address now because time is running out.

However, we are making improvements. We are now more considerate when it comes to what we buy. We also consider waste in a different way and many of us are thinking more about a sustainable future. Progress is being made but we can do more and this is where the 4Rs can play a significant role in helping guide both our thinking and our actions.

What Are The 4Rs?

The 4Rs are a simple way of reminding us how we can make a difference. Each step provides us with a different way of considering what we use and how we dispose of waste.

Every step has a clear focus on educating us. It helps us to identify the changes we can make. As such, used well the importance of the 4Rs is born out as an extremely important tool in our fight for a better planet.

1. Refuse

4Rs - Refuse

We all have the right to make a choice and refuse wasteful and polluting products. For too long, we have been buying products that have been packaged in a way that can cause environmental harm once we dispose of the plastic wraps, boxes, and cartons.

Around 20-25% of food waste relates to its packaging. From way too much plastic to too much cardboard and even oversized packaging. Needless and cost-conscious rather than eco-friendly packaging is causing problems.

Despite this, we can choose to refuse to buy items that contain single-use plastics or items that are individually packaged. Single-use plastic bags are a big problem and one of the reasons why our oceans are suffering. Commonly, these plastics cannot be recycled easily. They are therefore a problem for the environment.

A number of international policies are either now in place or planned to help address the issue. The first policies to limit our use of plastic bags emerged as early as 19911. And further moves are in place to limit cosmetics containing microbeads that end up in our waterways. The EU perhaps making the biggest policy commitment - by banning many single-use plastics as soon as 2021.

Choosing alternatives to wasteful single-use plastics and other pollutants

Despite this, there’s more to do. To make a stand or change we now have more options than ever before. Around a trillion plastic shopping bags are still used each year. To add to this, almost 500 billion plastic bottles are sold globally.

This is just scratching the surface because there is more to consider. Such as one million coffee cups being sent to landfills, our use of plastic straws right through to receiving paper bank statements.

Fortunately, if we refuse to purchase or use these items then we are reducing their harm. So, we can opt to use eco-friendly reusable straws or long-lasting plastic bags while we can choose to use our own travel mugs which coffee shops are now happy to refill. And of course, say no to plastic bottles.

The first step towards understanding the importance of the 4Rs and making a difference is to Refuse. Doing so decreases demand. Subsequently, the manufacturers and producers have to then think about less wasteful and sustainable alternatives.

2. Reduce

If we really want to reduce waste then we should think about how we can make that happen. If want to use less waste then we need to purchase less. This requires consumers to be more mindful when they do make a purchase.

Therefore, consumers should think about how much they need that particular item. They should also consider how much they will use it.

For decades we have lived in a throw-away society. Instead of repairing items, we throw them away and replace them. There are many ways that we can reduce and that can help to significantly reduce waste.

We should think about using reducing our use of coffee cups or throw-away coffee pods, especially when we have other options available

Cheap clothing is another prime example. While cheap clothing is perfect for those who cannot afford more expensive items, it is important to consider how cost-effective they are. If they need replacing in several months, then it might be worth paying more.

The reality of the situation is that people are not aware of what happens to their clothes when they throw them away6. You can simply reduce the environmental impact of your clothes by choosing sustainable fashion that will last longer and shopping with ethical clothing brands or buying second-hand from thrift shops.

Reducing our use of resources

It’s not just about waste either. We can even reduce the amount of water we waste. A simple water butt can help you to use rainwater instead of water from the tap. It offers the same benefits, can save on money, and help to reduce water waste.

Our consumption of energy also has a knock-on environmental impact. Have a read-up on how you can save electricity at home and school. You’ll not only be helping to reduce demand for non-renewable energy you’ll also save money.

When buying for other people think too about waste. Consider giving plastic-free. And as we approach the season of cheer there’s no better time than to think about a zero waste Christmas.

So the next step in realizing the importance of the 4Rs is reducing waste and is all about making a conscious effort to look at the bigger picture. We are all too quick to throw things away without a single thought for what happens to waste. To reduce waste, we need to reduce what we buy and use and consider limiting ourselves to essentials. It is as simple as that.

3. Reuse

Reducing waste is not just about reducing what you purchase. It is about considering what you can reuse. This essentially means not putting it in the waste but using it for another purpose.

When we stop to think about the waste we generate and how we could reuse a lot of what we buy, it is clear to see the difference we can make.

This can range from the smallest of items such as reusing jars to store pens or screws to repurposing wrapping paper at Christmas or Birthdays.

One of the biggest culprits of waste is fast-food establishments, with packaging having a recovery rate of just 29%2. Many will serve up their food in plastic containers with lids.

These are more useful than many realize and they can be used as makeshift lunch boxes or to store crayons for the children. We can even reuse plastic and turn them into eco-bricks that can be used to build entire buildings3.

This is about being innovative and forward-thinking. It is surprising how many items can be reused and repurposed.

To add to this, we can also avoid using items completely and purchase read-made reusable items. This can include coffee cups, cutlery, and even shopping bags. The more we reuse, the less we need to produce. This prevents waste, reduces manufacturing processes and emissions at the same time.

One of the biggest ways of reusing items is through upcycling. People are now becoming more and more creative and so, it is now possible to take tired, worn items and upcycle them into beautiful pieces that can be reused. It is this kind of clever thinking that can make a difference.

Sometimes you might find another R mentioned - “repair.” Similar to re-use when items become broken or worn out repairing them can extend their life. This is especially true of electronic devices which can result in e-waste. Whereas we can find ourselves tempted to upgrade to the newest model repairing a cracked mobile phone screen can save money and means one less device needs to be manufactured in the first place.

4. Recycle

When it comes to waste management, recycling items is the final option and the final R as we look at the importance of the 4Rs. Instead of throwing away clothes, you can donate them to charity. Do make sure that you sort and clean all items before recycling to increase the likelihood they actually do in fact get recycled.

To ensure we correctly dispose of items recycling is the first option wherever possible when our products reach the end of their useful life. Along with this, it also means that items can be repurposed.

We realize the huge problem plastic waste cause for the environment but when the majority becomes recycled, we can reuse it in other ways. Bottle tops can become car batteries and reusable plastic bags while plastic containers can be turned into toys. The possibilities are almost endless and recycling technology is constantly improving and that is a real positive in our quest to reduce waste.

Together We Can Make A Difference

It is no longer enough to generate waste and throw it away without a care. We need to take responsibility for our actions. This is a vital aspect of turning around the environmental problems we’ve caused whilst working to set things right.

The truth is, for centuries we have been creating needless amounts of waste. This waste is causing havoc with wildlife. It is killing animals, it is altering food chains, and causing problems with global warming.

The future of our environment is in our hands. We can take control of our destiny but it requires a considered approach. When we begin to think about what we buy, as well as what we reuse and recycling, we can make a difference. This proves that the importance of the 4Rs is more prominent than ever before.

It is going to take a joint effort but there is no reason why cannot do this together. Remember, Refuse, Reduce, Reuse, Recycle.
