Cut back on single-use plastic and start using reusable coffee mugs for when you’re on the go.

Reusable coffee mugs have become popular among coffee-lovers and environmentally-conscious consumers and for good reason. Every time you buy coffee at your local coffee shop, you most certainly get your favourite hot beverage in a disposable cup which is not biodegradable. Billions of coffee cups are being thrown annually and only a small percentage of these waste are being recycled. Most of the disposables end up in landfills and floating in our oceans, threatening marine life. With regular use, you can significantly reduce your own waste by simply making a switch to reusable coffee cups.

Not only are disposables bad for the environment, they’re bad for our health too. Experts suggest that disposable cups, while made from paper material, are lined with plastic to prevent liquid from soaking through or leaking out. This plastic lining releases nasty chemicals like BPA (bisphenol A) that could leach into your drink and potentially cause serious health problems like heart diseases, hormonal imbalance and many more.

So are reusable coffee cups safer then? Let’s find out.

Reusable coffee cups do not leach nasty chemicals

We already know the potential health risk of using plastic containers especially if they get in contact with heat. They release harmful chemicals and toxins that leach to our beverages. The most common harmful compound is BPA (bisphenol A). It is a hormone disruptor that disrupts the endocrine system and is often considered to be carcinogenic.

Reusable cups, on the hand, are made from a wide range of materials that are considered safe and eco-friendly like toughened glass, stainless steel and silicone. These materials are safe to use for hot or cold drinks and 100% BPA-free. They do not also add any unpleasant taste to your beverage like plastic containers do.

Reusable coffee cups made from toughened or tempered glass like KeepCup’s Brew Cork are easy to clean, comes with a cork sleeve for easy handling and fits most coffee machine group heads which means you can take it with at your favourite coffee shop and take advantage of their discount (some coffee shops offer discounts for patrons who bring their own cup).

Double-walled insulated stainless steel coffee mugs are also popular because they do a good job in keeping your coffee or tea warm for up to 6 hours. The food-grade stainless steel construction prevents altering or imparting flavors which helps protect the purity of your favourite beverage.

Reusable cups protect the environment

Throughout its life cycle, disposable cups have huge amounts of carbon emissions. Manufacturers use a lot of resources like petroleum in making them and when they are disposed of, most of them are piling up in landfills, incinerated or littering our oceans.

On the other hand, reusable coffee cups are made from eco-friendly materials and help conserve natural resources. Glass, stainless steel and silicone are highly recyclable. Aside from the fact that using reusable coffee cups are economical in the long run, using one reusable coffee cup can help save a tree from being cut down.

Remember to always clean your reusable coffee cup

It’s also important to always clean your reusable cup to prevent germs from building up and mould from growing. Not only that, you also want to wash away any residue left behind from your previous beverage. Check your manufacturer’s notes for care and washing instructions. Some reusable cups are dishwasher safe while others are not.
