Giving up single-use plastic products like straws and drinks bottles is an admirable thing to do, but is not particularly convenient, especially when it comes to drinks containers. A solid, re-usable plastic or aluminium bottle is the only alternative but means carrying it around in your hand all day or making sure you always have a bag big enough to carry it in.

This becomes even less convenient after you’ve finished the drink and before refilling it as the bottle then becomes a hollow cylinder that takes up space needlessly. What’s more, if you’ve finished your drink it’s relatively easy to forget about it and leave it behind, which doesn’t exactly help the cause.

The challenge

The challenge this month then is to come up with a reusable drinks bottle that is also easy to carry around. Your product could include revolutionary material innovations or some kind of inventive mechanical properties. Whatever you come up with it must be lightweight, reusable, easy to carry around when hiking, camping, travelling or spending time in the gym, and 100% recyclable.

The idea we have in mind will be revealed in the June issue of Eureka! Until then see what you can come up with. Submit your ideas by leaving a comment on the Coffee Time Challenge section of the Eureka! website or by emailing the editor: paul.fanning@markallengroup.com


The solution

Our solution to last month’s Coffee Time Challenge to create a re-usable water bottle to tackle the problem of single-use plastics comes from US startup Hydaway Bottle, that recently released the latest iteration of its collapsible drinks bottle, the HYDAWAY H2.0.

The HYDAWAY H2.0 is a lighter, slimmer version of the original bottle launched in 2015. It is a collapsible, non-toxic water bottle made from BPA-free plastic and holds either 500 or 850ml of water when fully expanded. Once you’ve finished your drink it simply collapses into a flat disc just an 3800mm high, so it can fit in your pocket.

The new design also features two different lids, as well as the original cap lid there’s now a spout option which is for hydrating on the go either while running or at the gym. The spout lid also includes a carbon filter to remove tastes and odours from public fill stations.

Every year more than one-trillion piece of single-use plastic enter the waste stream, a lot of which finds its way into the oceans turning into microparticles that then end up the food chain. Since 2015 Hydaway says its bottles have prevented over 1100 metric tons of plastic waste reaching our oceans, streets and landfills.

The Kickstarter campaign reached its $20,000 funding goal in 18 hours and has gone on to reach more than $180,000 to date.

Coffee Time Challenge is just a bit of fun, but it is based on a real engineering solution. If you send in your ideas by using the comment button below, we can add your solution as an alternative – perhaps something funny, practical, cheap or, of course, innovative.

Lightweight: Existing plastic bottle that has been bought and used for another purpose.
Reusable, see above.
Easy to carry around: Easier to carry empty than full. In the examples you give, hiking, camping, travelling, or in the gym, you will already be equipped with a bag or portage of some sort in which the bottle can be carried. Why would anyone carry a bag that is not big enough for everything they need to carry?
The best solution is to re-use what you already have and which is already manufactured and suitable for the task, rather than inventing and manufacturing more stuff.
Regarding the " if you’ve finished your drink it’s relatively easy to forget about it and leave it behind" problem, stopping people being forgetful is probably a separate issue?
