Doesn't that mostly come from the peel though? I thought it was the waste that they used to get orange oil from, not the fruit.

They do extract it from the peel which is the byproduct of citrus juicing operations. I'm not an industry expert but I would expect that D-limonene would probably not replace a lot of petroleum or latex based tires. Sounds like a boutique product.

If it did become widely used I expect it would have the upside of a much nicer smell when the mobs start to burn tires on the barricades...
