palm leaves for a thatched roof?
In mexico, the most common, old style roof is layered palm leaves, however, a big wide palm leaf, not coconut style. I visited cozumel right after a major hurricane. The only roof not leaking was palm thatched with a cord mesh holding it down. The major negative would be rain catchment and frequent maintenance. Otherwise, very comfortable.
Rastra sounds similar to aircrete, but with the air bubbles made of something that is preformed and lightweight. Aircrete has a problem in that it can collapse while curing.
Rastra? How much suitable waste plastic is on the island? Enough to sustainably supply a portion of the islands building needs? Is a rastra structure permittable? Could you open source the technique to make rastra, itself?
