How green is your hessian shopping bag?

Listening to "In Our Time" today, about Macromolecules.

Towards the end of the programme the scientists explained that in order for a hessian (or was it jute?) bag to be truly better for the environment than a plastic carrier bag (taking the whole process into account from growing to decomposing), you have to use it 130 times for every one time you would use the carrier bag.


So if you use a carrier bag twice, you have to use your hessian bag 260 times.  If you use a carrier bag 3 times before discarding it, you have to use your hessian bag 390 times.

Life's never simple.
