As Gordon says you can use the inner layer, the "Trama" layer as tinder, it can be used without processing by drying well but is traditionally used to make "Amadou" where the Trama layer is Boiled with I think a Peat and Lye solution (correct me if I'm wrong I'm not 100% on that)
Once you have removed the trama layer dont throw the rest away, once dried you can use it for fuel. I have made amadou a few times in the past and not had to use salt peter and the likes.
