There is a future where we will no longer buy single-use plastic bottles. I feel it, I believe it. If we decide to bring a water bottle with us, we may never need to buy a plastic bottle.
What about toothbrushes? A truly ecological toothbrush would be ideal. Almost all of them are made of plastic.
There are also bamboo ones!
There is a reason why plastic toothbrushes are so extraordinarily more popular than those in bamboo. They are faster to produce, look great, last a long time, and are exceptionally easy to clean and maintain.
Plastic is a far superior material when it comes to making toothbrushes.
But there is plastic and plastic

Instead of opting for plastic based on fossil fuels, Reswirl (this is the name or of the protagonist of this post) is made from a cassava-based (non-GMO) biopolymer called PHA. This biopolymer naturally biodegrades in soil or water. The most interesting feature of Reswirl, however, is another: when you finish using it (every 3 months) you get a new one with an envelope already stamped. You take the new one, put the old one in the bag and send it back to the factory.
At the factory, Reswirl is cleaned, shredded and recycled in a new ecological toothbrush. Pure and simple circular economy.
What if I don't return it?
If the Reswirl is thrown rather than replaced, it will biodegrade in any case, not contributing to the large quantities of plastic waste in our land and oceans.

How is Reswirl made?
Reswirl's plastic design is familiar to the touch, but has a hollow cylindrical body to minimize the amount of material and maximize decomposition capability. The bristles are also bio-based, made with a special nylon derived from castor oil. The bristles also biodegrade, but a little slower: this is why the company believes it is much better to have an integrated approach.
In short, it is like any other toothbrush but, unlike other plastic toothbrushes, it will not remain a problem for future generations.
