The byocup silicone story

We are conscious of the fact that manufacturing reusable cups also   has an environmental impact, so we have put a process in place to    recycle the cup responsibly.

At the end of its life as a byocup, please return it to us and we   will forward it to a silicone recycler in India who will turn it into   charity bracelets or key rings. 

There is also a ‘break even point’ in the life of a reusable   coffee cup, which is the point at which the silicone cup becomes more   environmentally friendly than the paper cup.  The longer you use it, the    greater the benefit.

Research tells us it takes 0.55MJ on average to make a regular   paper cup*. In comparison, the equivalent grams of silicone produced use   1.24MJ of energy**

Given these measures, and allowing for weight, the byocup breaks even after 10 uses.
