The concept of zero waste is actually pretty simple: essentially, living a life where nothing ends up in a landfill (aka: zero waste).
All waste that is generated should be converted into a new resource. For example, food waste can be composted and organic fertiliser can be created, waste paper and other ‘organic’ materials can be recycled and reused. The consumption of plastic does make creating a zero waste lifestyle incredibly difficult to do, because not all plastic can be recycle (there are over 7 different types of plastic: https://www.qualitylogoproducts.com/promo-university/different-types-of-plastic.htm) .
So, with that in mind, reduction of both waste and consumption is by far the most important aspect of achieving a ‘zero waste lifestyle’.
Our lifestyle and consumer behaviour should cause the least amount of pressure on the environment. So, avoid single use disposables, avoid eating packaged food and bottled water. Reuse things, and upcycle old and unused materials, whilst trying to cap your spending. And of course, you can become more creative when you need to buy things.
It’s never too late to small, and little changes like the above will help start the journey to zero waste.
