Water bottles can be classified into two types based on the feature of whether they can be recycled. Reusable drink bottles are often made by stainless steel 18-8 (SUS304) that is BPA-free. Since it can be reused, the quality as well as the safety of this type of bottle must be assured. Disposable water cups, also known as single-use water bottles, are designed for bottled water. Disposable water bottles are often made by plastics that has low cost yet strong performance. They are light in weight and offers people convenience.
It is quite obvious that a single-use water cup is cheaper than a reusable stainless steel water bottle, so why do people keep buying reusable ones? Actually, apart from the health and environment reasons, people also take the economical reason into consideration when picking up bottles for water intake.
“Really? A stainless steel water bottle is way more expensive than a plastic water bottle”, you may question. In fact, this statement is conditioned by the time span. Stainless steel water bottles are reusable, which means you can consume water with them over and over again. Every time you complete the amount of water in the bottle, you just have to refill the bottle without paying extra money as you have bought it at the very beginning.
A quality stainless steel water bottle is capable of offering 5 to 10 years of service without breakage or leakage. So if you consume water with a disposable plastic water bottle everyday and throw it away after hydration (it is only designed for one-time use), a single reusable stainless steel water bottle can help you save 1,825 bottles in 5 consecutive years! This is just a brief reckoning, and the detailed calculation will be shown in the next part.
By contrast, a disposable plastic water bottle are supposed to be purchased repeatedly so as to meet your daily hydration. Your money is not only spent on the water, but also on the plastic containers. As time goes by, plastic water bottles are bound to cost you more as they can not be recycled. Therefore, in the long run, drinking water with stainless steel water bottles costs less and is also an eco-friendly and healthy lifestyle.
II. How Much Can a Reusable Water Bottle Hold?
Averagely, a reusable stainless steel drink bottle has a capacity of 25 oz, whereas a single-use plastic water bottle can hold 17 oz of water. Put simply, a stainless steel water bottle requires fewer refills and saves money on redundant plastic bottles.
It has been well-documented that the average human is supposed to consume at least 8 cups of water (approximately 64 oz) on a daily basis. Therefore, if you get hydrated with a 25 oz stainless steel water bottle, you can reach a day’s water consumption goal by completing 3 bottles. However, if it is a plastic water bottle of 17 oz, then you may need to drink 4 bottles to do the same thing, which is also partly acceptable yet creates plastic wastes (bottles).
