Pictured above is a travel mug made by bringing together a chemist's Berzelius glass and a "Mini" sleeve from MugToGo. They say their sleeves are biodegradable and the ones I have look biodegradable to me. Berzelius glasses are heat resistant and somewhat shock resistant too.
So here it is - a way of having a "repurposed" travel cup.
Apart from that - you can repurpose this type of chemist's glass by integrating it into decor [view examples below]
