It's about time we stopped wasting money on boards for every tournament and found a solution that benefited everyone!
For temporary events (under license) you will need to have "safety approved" wood, boroughs often prefer to ok a supplier (and your designs in full) rather than just allow you to turn up with a 'here's one I made earlier' approach.
HDPE and aluminium (as John suggested) would be best, but the initial investment cost will be high. All soft wood will only last one season, hard wood will be crazy heavy / expensive.
For the record we never wasted any of our wood (or money), the wood was always re-used (or re-purposed into something else) and we always sourced the most cost-effective way of creating tournament courts (including looking into more permanent solutions).
The transport and storage costs of a more permanent (modular?) solution will most likely negate the imagined savings in finance / waste unfortunately.
Pique's idea of selling panels has also been hashed out in the past and there are many problems: having ownership of ad hoardings at HH is most likely a non-starter (they already sell advertising at the track and they would own the income as it'd be on their property). For tournaments/events you would essentially be selling the same ad space twice (we would no longer be able to source sponsors for events as they'd be no visibility available for sale), which is a no-go unless there are no other tournament fees to contend with (not the case: although courts do seem to make up ~30% of the total budget).
Your best bet here is to find a (super cheap) storage facility first and a (super cheap) source of materials (that will stand the test of time), you then need to fundraise the cost and sort out some sort of "safety approved" rating (easier than it sounds) and transport as-and-when you need it.
