Plastic has a bad reputation: it is made of petroleum and you find it as litter. Yet it is not necessarily the enemy - it is a convenient packaging material and alternatives are not always better either. What makes us less happy are the harmful substances in plastic such as plasticisers. And that gave us the idea to look for alternatives to plastic drinking cups and lunch boxes. We ended up with stainless steel, or SS. And so we made a list of fine stainless steel drinking bottles and cups from Dutch and Belgian companies with a sustainable mission.
What exactly is stainless steel a material?
Before we praise stainless steel to the skies, it is good to know a little more about this material. Stainless steel is a mixture of different metals, also called an alloy. It consists of iron, chromium, nickel and carbon and is known for its strength and rust resistance. Although stainless steel is reusable and fully recyclable, its production requires a lot of energy and raw materials. Mining metals, such as nickel and chromium, damages natural areas and emits a lot of CO2. In addition, mining and production can release harmful, toxic substances.
Remember: a stainless steel water bottle is something you choose for life
According to research by the Consumers' Association, a stainless steel bottle must be used for more than 36 years to be equivalent to a reusable plastic bottle in terms of environmental impact. For double-walled stainless steel bottles - you know, the ones that keep your drinks hot or cold - this even runs to more than 70 years. This makes one thing clear: if you choose stainless steel, you have to use it a lot and for a long time in order for it to really be a more sustainable choice. A big advantage of stainless steel is that it does not contain harmful substances such as plasticisers, which are present in some plastic products. We previously wrote an article on plasticisers. Moreover, stainless steel does not retain odours and flavours and is resistant to heat, allowing you to enjoy both your ice-cold smoothie and your steaming cup of tea carefree.
The nicest stainless steel drinking bottles and cups
We dove into our kitchen cupboard AND scoured the internet in search of the most beautiful and sustainable stainless steel drinking cups and bottles. These are our favourites! We also tell you what we could find about these companies in terms of sustainability. All examples mentioned are Dutch or Belgian entrepreneurial stories.
Strict rules for drinking cups in Europe
In Europe, strict rules apply to materials that come into contact with food and beverages. The REACH regulation (Registration, Evaluation, Authorisation and Restriction of Chemicals) determines which chemicals are allowed, and European Regulation (EU) No 10/2011 sets additional requirements for plastics used for food and drink products. This strictly regulates harmful substances, such as certain plasticisers. Even if European companies have their drinking cups produced outside the EU, they must ensure that they comply with European legislation. Yet there are manufacturers outside Europe that do not have to adhere to such strict standards. Some cheap drinking cups offered through international online shops may therefore not be able to meet European safety standards. Want to be sure you are making a safe choice? Then look out for labels and certifications such as BPA-free or REACH-certified and buy it from a European brand. Let's find out just that for you.
