Why It’s Important to Reduce, Reuse, Recycle

Reduce, reuse, recycle. It’s more than a mantra, it’s what we need to do to slow down the frightening pace of climate change.

An Intergovernmental Panel on Climate Change (IPCC) report on climate change was described as a "code red for humanity" by UN Secretary-General António Guterres. It stated that human activity is changing the climate in unprecedented and sometimes irreversible ways. It warned of the impact of doing nothing, from extreme heatwaves to droughts and flooding. But it also offered some hope. If we cut greenhouse gas emissions, it could stabilise global temperatures. But we have to act.

The need to reduce general waste

It’s so important to reduce, reuse, recycle to help prevent any waste ending up on landfill sites or leaking into the environment. When organic waste rots in landfill, it gives off methane. Methane is one of the greenhouse gases that contribute to climate change. Plastic leakage into the ocean is also a major threat to wildlife and ecosystems. Another reason we should reduce the amount of waste is that we’re simply running out of landfill space. Although much of the waste in the UK is now sent to Energy-from-Waste facilities to be incinerated for heat and electricity, and that reduces methane emissions compared to landfilling, it is still better to reduce, reuse or recycle.

Reduce, reuse, recycle: Changing our habits

Think of ‘reduce, reuse, recycle’ as the hierarchy of reducing your environmental impact. Reducing waste is the best option, followed by reusing and recycling items wherever you can.

Reducing waste

Reducing waste in the first place saves energy, precious resources and raw materials. Examples of how you could reduce waste could include things like:

• Saving energy by not leaving appliances on standby;
• Turning off the tap when you brush your teeth to save water;
• Putting your food waste onto a compost heap instead of in the bin.

We can all make a difference when it comes to reducing waste. Some of the UK’s biggest companies have committed to reduce, reuse, recycle policies. Aldi, Asda, Lidl, Sainsbury’s, Morrisons, Waitrose, and Tesco signed up to the UK Plastics Pact, which led to the elimination of over 700 million pieces of plastic waste between 2018 and 2025. They have now moved beyond that by joining the 2026 UK Packaging Pact, which covers all materials. While Iceland was a pioneer with a stated aim to remove plastic packaging from all its own-brand products by 2023, they conceded it will take longer than hoped after citing the Covid pandemic and industry challenges as reasons for missing that target.

Reusing items

There has been a huge drive to encourage us to ditch single-use items in recent years. The government has banned plastic straws, cotton buds, and drink stirrers. We strive to fill up our reusable water bottles and take our reusable coffee cups to Starbucks. All for good reason.

The more items we reuse, the more energy we save and less precious resources end up in landfills. It can be as simple as using old glass jars for storage, or as creative as turning that old bedside table into something unique. Reusing is an integral part of creating a circular economy. 

Recycling

Ah, recycling. So confusing, but so crucial. It might seem annoying to have to meticulously sort your glass, cans, and plastic. However, it’s important that you do. You can recycle materials like glass and aluminium indefinitely and turn them into brand new products. It takes less energy and resources to make an item from recycled materials than it does to make something brand new.

While recycling is not a seamless process by far, it’s pretty genius. Those water bottles you recycle can end up as garden furniture or clothing. Glass becomes new bottles or jars. And that Diet Coke can? It's recycled and back on your supermarket shelf in as little as two months!

So don’t roll your eyes when you hear ‘reduce, reuse, recycle’ because it’s more than worth it. We can all make a difference and slow down the pace of climate change, one aluminium can at a time.
