Is It Healthy To Eat An Ooho Water Bottle?

A water containing bubble that you can eat has taken the Internet by storm. But, how safe is it for us to consume this container?

Skipping Rocks Lab has offered their solution to the plastic waste problem – a biodegradable water container that you can consume, called the Ooho. This project’s heart is definitely in the right place, as Americans alone throw away 38 billion plastic water bottles every year, while devouring more than 17 million barrels of oil annually to meet plastic bottle manufacturing requirements.

This project was originally launched in 2014, but has garnered attention now as the company launches a crowd funding campaign.

The London-based, sustainable packaging start-up want to transfer from selling their water bubbles at pop-ups to piloting their water bubbles at major sporting events in 2018. They intend to pilot the Ooho at UK events, such as the London marathon, and Glastonbury, the UK’s most famous festival. With a huge 750,000 bottles of water being handed out at the marathon alone, it’s easy to see what an impact the biodegradable bubble will have on plastic waste.

How Is The Ooho Water Container Made?

The developers based their concept on seaweed. They create the containers by dipping ice into calcium chloride and brown algae extract. The ice melts leaving a gelatinous membrane intact to contain the water. It is flavourless, but flavours can be added.

Skipping Rocks Lab was founded by three London-based design students. They share, “For 2 years, we have been developing the material and innovative production technology, for which we have recently filed a patent application. We are supported by the Climate-KIC accelerator based at Imperial College London. We want to solve the plastic waste problem and reduce climate impact from packaging.”

This container makes a lot of environmental sense, as the membrane decomposes in four to six weeks. The company also claims that it is less expensive to make the Ooho than plastic bottles. As a result, this breakthrough is important for solving the plastic waste crisis.

However, the question remains whether or not we should be consuming the Ooho container.

Should You Eat It?ooho

It would be better for your health if you didn’t. While calcium chloride is a recognised food additive it still has a toxicity rating and ingesting it can lead to complications. These complications are as a result of a process called hydrolysis, which takes place when calcium chloride reacts with water and creates excess heat as a byproduct. This can result in serious irritation of the moist linings of the body. Such as your, nostrils, mouth, throat, lips, eyelids and ears. In higher doses it can result in gastrointestinal upset, vomiting and abdominal pain.

The FDA regulates calcium chloride at 0.22% per unit of beverage. While the product would have to comply with this regulation before it is sold, one should be careful of consuming too many in a short space of time.

Should You Fund The Ooho?ooho

Absolutely! The positive impact for the environment would be staggering. At this point, Ooho uses five times less CO2 and nine times less energy to produce than PET.

All you need to keep in mind is:

  • You should  dispose of the container rather than consume it.
  • You should moderate your intake.

    I worked for a company years ago where we used calcium for certain parts of the product. The product was a classified item. Calcium was used in several forms, all of which were very dangerous if water were to get on the calcium. The way we processed the calcium was the most dangerous job I ever had. OSHA did not exist then.

    Calcium is dangerous as a solid, and reacts violently wih water. Calcium chloride as a solid is a lot less dangerous. Yes, the reaction with water is exothermic, although heat is never referred to as a by-product, since it is not a product but energy. Finally, if it is in the bubbles, it will probably already be ionised, and therefore the only toxicity to worry about is the concentration max of calcium ions and chloride ions.
