Tyre Disposal Costs, page-37

the very competitive tyre collection market is already nationally controlled by established businesses. so:
a) pg1 cannot get the feedstock to have scale.
b) only way to win access to the feedstock is to charge very low collection rates. rates so low, that collection will likely be at a loss.
c) Brisbane only. and why Brisbane?

the whole thing is a great blue sky concept but again, if you were to have put all the investors money (the bulk of which has gone into managements pockets) into blue chip stocks instead of this bloodbath, they would actually be sitting really pretty right now.
