Never forget this!

We feel instinctively that using reusable products should be better than their disposable alternatives.

They produce less waste AND provide a better experience.

What we don't often consider though is the number of times we must use a product before it makes up for the environmental deficit it causes.

CIRAIG is a research group focused on sustainability and life cycle thinking around products, services and systems.

They produced a report in 2014 comparing the different types of reusable coffee cups on the market to find out which one was the most sustainable.

What they found was the way you washed your cup had a HUGE impact on its eco-friendliness.

For example, if you wash your cup every day with hot and soapy water it might take over 1,000 uses to make up for the environmental deficit caused during its material sourcing, manufacture and delivery.

So if you don't read any further, please just internalise this part alone.

Not only will you save water, but you'll reduce your energy usage drastically too. 

In fact, if you use a dishwasher it will only take between 30-100 uses to make up the environmental deficit of producing your cup.

What the study also found was that reusable cups made of polypropylene would provide you with the fastest environmental savings.

Here's a snapshot of their findings:

*it takes less than 30 uses to make up the deficit of producing polypropylene cups.

So now you know the technical details, it's time to decide whether you actually need a cup of your own.

My advice is this. If you don't travel or buy takeaway coffees all that often, please don't buy a reusable coffee cup!

Normal mugs are perfect for home use in the vast majority of cases, and it's far more eco-friendly to have your coffee served in ceramic mugs sitting-in at coffee shops.

Yes, there are occasions when it's better to have a cup with a lid. Especially around laptops, or with kids running about.

But if you don't fall into either of these categories, take a moment to consider if you really need one...

Ok, agreed that you 'need' one and are going to use it regularly enough?

Alright, let's move on 🙂

Remember the science we didn't want to share with you unless you had good intentions? It's up next.

It has to do with behavioural psychology and the impact your own buying decisions can have on OTHER people.
