Morphology

nonsustainable = sustainable (semi-transparent) = non + sustain + able

The word is transparently formed by adding non- to sustainable, but this sense is somewhat specialized and metaphorical because it applies to arguments or positions.

Etymology

Nonsustainable breaks into non- 'not' and sustainable, which comes from sustain meaning 'to hold up' or 'support', like the common word support. So a nonsustainable argument is one that cannot be 'held up' by facts or reason.
