Glass water bottles

Plastic is really convenient indeed to drink water anywhere, anytime. But now, glass water bottles and glass jars are making their way back and are in fashion. Consumers are slowly changing their heatlth awareness and habits and are deciding to use reusable glass water bottles instead of plastic or metal since a few years now.. In a survey of more than 4,000 consumers this year by EcoFocus Worldwide, a research and consulting group, 37 percent said they were extremely or very concerned about the health and safety of plastics used in food and water packaging, compared to 33 percent in 2010. EcoFocus also found that 59 percent of the consumers it surveyed used reusable water bottles always or often, up from 56 percent in 2010. More and more people are looking for glass water bottles and glass jars.

The basic concern is that chemicals used in plastic packaging can transfer into the products the consumer is drinking or eating. Therefore more and more beverage and food manufacturers are turning to glass jars and glass water bottles.

BPA or Bisphenol A is a chemical found in plastic water bottles and plastic jars. Many studies have shown that slowly these chemicals can transfer into what you are eating and drinking and it increases the risk of cancer, obesity and diabetes. Now scientists at the Institute of Environmental Assessment and Water Research (IDAEA-CSIC) and the Oliver Rodés Laboratory have focused on those constituents which can be transmitted from the plastic bottles to water. More specifically, they have analysed five types of phthalates (esters of phthalic acid), diethylhexyl adipate (DEHA), octylphenol, nonylphenol and bisphenol A (BPA).

Many plastic bottles are now using BPA free materials, but why wait another 10 years from now and discover that these new plastics are not safe either. Changing to glass water bottles and glass jars is just the safest way to go.

Coca-Cola is expanding the distribution of products — Coca-Cola, Diet Coke, Coke Zero and Sprite — that it sells in eight-ounce glass bottles, and S. C. Johnson now sells a line of reusable Ziploc containers that can be used in a microwave, a freezer and, without their lids, even in an oven up to 400 degrees. “It’s part of our overall effort to increase packaging diversity so that people have more choices of packaging and portion size,” said Susan Stribling, a Coca-Cola spokeswoman.

JW Marriott Chain of hotels just asked Rockwood Glass to do a trial for 100 000 recycled glass water bottles for their hotel rooms in the region of Southern Thailand – Phuket. JW Marriott and Rockwood Glass are very excited about this new partnership and hope it will be the start of a new trend in other hotel chains around the world.

Glass is just better in every way: better for your body and better for the Earth. It is chemically stable and doesn’t alter the taste of its contents. You may have experienced first hand how certain containers leave what’s inside them with a strange taste which is definitely more than just water. Far less permeable than plastics, a glass water bottle won’t allow any unwanted flavors or chemicals into the water – meaning your drink always tastes just like what you put in it. Glass jars and glass water bottles fix the problem of keeping the outside out while simultaneously letting you rest at ease knowing that with every sip from your bottle, you’re just drinking the water and not the bottle!

So don’t hestitate, switch from plastic to glass water bottles or glass jars. Your end buyers are reading more and more about the above, and as they get more informed, sales in plastic containers will go down and glass containers sales will go up. Rockwood Glass is here to make your project sustainable and a success on the long run!


Here are a few more reasons why glass water bottles and glass jars are better than plastic bottles for the environment and for you:

Better for the environment:

  • Roughly 2.7 million tons of plastic are used each year worldwide for disposable drinking bottles. Less than 1% of all plastic is recycled, meaning 99% of plastics are incinerated or end up in a landfill.
  • Americans buy an estimated 29.8 billion plastic water bottles every year, and nearly 8 out of every 10 bottles will end up in a landfill. Once there, it takes over 500 years for plastic bottles to break down.
  • It is estimated that the production of plastics accounts for 4% of the energy consumption in the United States. Plastic is bad for our Earth, and uses up valuable resources!
  • Glass is the only packaging material generally regarded as safe by the U.S. Food & Drug Administration. Glass is made from all-natural, sustainable raw materials, is 100% recyclable, and can be recycled endlessly with no loss in quality or purity.


Better for you:


  • Glass, unlike some plastic bottles, does not contain any harmful chemicals such as BPA, phthalate, PVC, or polycarbonate, so nothing can leach into your water from a glass bottle.
  • Plastics made from polycarbonate resin can leach bisphenol-A (BPA), a strong endocrine disrupter, into its contents. Studies suggest that BPA may negatively affect reproductive organs, such as the breasts and prostate, as well as causing potential heart problems.
  • You can save money and Earth’s resources by utilizing an eco-friendly, reusable, recyclable glass water bottle.
  • Glass is taste-neutral, so no plastic or metallic taste will affect your beverage. Try our taste-test challenge: Sample various beverages from glass and plastic and let us know what you find out!
  • You can safely refill your glass bottle as much as you want, and drinking the recommended daily intake of water means a healthier you.


The Long History of Glass

If we look at any of the materials used to make the water bottles on the market today, most of them have a relatively short history of human use. The first production of plastic and stainless steel did not begin until the mid-1800’s.

In contrast, the first known evidence for the use of glass as a container object span back as far as 1500 BC, when ancient Egyptians fashioned hollow glass containers by covering a core made of sand with molten glass. When the glass cooled, the sand was removed and a simple glass cup was formed. Evidence of early man-made glass goes back much further still to 4000 BC or possibly earlier, leaving open the possibility that mankind has been using glass containers for many thousands of years.

What we can derive from this is the safety of glass as a container.

Compared to the questionable safety record of modern industry, glass is thoroughly enshrined as the leader in contamination free containers. You can always shatter the chemical conundrum of wondering what strange industrial techniques were used to make your modern plastic or metal water bottle by just sticking with good old glass.

While glass production is certainly not without its pollution-byproducts the impact of manufacturing glass is far less severe than plastic or stainless steel. Most pollution from glass production is the result of emissions from furnaces used to heat the glass and is not inherent to making the glass itself.

To further compound the environmentally friendly nature of glass we have its incredible recyclability. It can be endlessly recycled.
