I was very impressed to see Cactus making a range of backpacks out of up-cycled canvas from billboards that would otherwise be sent to landfill. I love panniers and use them every day and really like the idea of having a pannier made from recycled material. If you think this is something you would like to buy, let Cactus know customerservice (at) cactusoutdoor.co.nz and if there is enough interest, they may just start making them.
