What makes you think food prices will go up because a company, which
most likely uses the oranges to make juice, will use the waste to
supplement petrol?

Fundamentally, I'm against finding ways to keep the internal combustion
engine going, especially if it involves using food or food by-products. The
by-products should be composted and returned to the earth, rather than
burned.
Besides the use of citrus waste for animal feed (which may be good or
bad), but will make poultry and cow raisers look for alternatives, citrus
oil has uses as a bio-friendly cleaner, flavouring, and other uses listed at
the site below.
I imagine candied lemon peel will cost more, at the very least...

Direct Solvent Replacement being extremely useful, imo.
