I am big bag fanatic with a heart for sustainable fashion.
My cousin bought home a load of "Study in UK" prospectus in a very familiar bag from a British Council education fair. The very same material that my desktop covers are made of, the very same material my mother's complimentary shopping bag from
Jal (again from a home-accessories fair). Further observation lead to me realising that is the very same fibre used in certain adhesive plasters and surgical masks!
The fibre is smooth, soft, recyclable and very VERY light (as compared to a jute shopping bag). Technically called "Non-woven polypropylene", used mainly in promotional tote bags. ¹
Another alternative, in case where bio-biodegradability is the main criteria, there is
Hemp - the industrial variant, which looks and feels strikingly similar to the Hemp fibre.
If you were to read the Wikipedia page on
Hemp , you realise it's a wonderful,
wonderful plant. Every part can be made use of in a productive and environmental friendly way, in addition to being fast growing and requiring almost no herbicides in its cultivation. Best part? You can grow it in your backyard (at least so for me, for Indian climates facilitates it). Information on laws in India regarding its private cultivation seems unavailable on the internet, though I think one has to have a permit for this.
