It needs to be cheaper than cost of ‘virgin PET’ including the taxes levied on the material itself, technically. I haven’t done the math to incorporate the tax duties of the hydrocarbons used to form non-recycled PET but I assume currently most countries levy no tax whatsoever on PET itself, regardless of source?
