The Oyster River
Biodiesel Cooperative (Mike Briggs from UNH) uses the waste water from their
operation to water crops. It contains a little soapy residue that they
actually find to be a beneficial pest control.
The process being
patented and hopefully demonstrated in NH soon by Jim Proulx (Proulx Oil and
Propane) doesn’t generate any wastewater at all. I’m hoping to see some
tests on the fuel quality from that process in the near future, but if it works
it would be great.

Re: Biodiesel plant p2 opportunities
There are hazards using heated
methanol. A home grown plant in MA exploded and burned to the ground
because the thermostat malfunctioned and the temperature of methanol feeding
into the vat was a bit too high.
Handling caustics should be done
respectfully, too. I wonder if our green chemists can add any thoughts to

I am going to be P2 point on a biodiesel manufacturing
plant that is in the pre-design stage right now. To get a jump on this, I
was wondering if anyone has had experience with biodiesel manufacturers, BD
plant design, and pollution prevention opportunities. From my
understanding of BD production, the entire process should generate next to no
hazardous waste and uses methanol and NaOH/KOH as parts of the reaction.
Does anyone have any P2 opportunities (can include water or energy reductions,
methanol recovery, increased reactor efficiency, etc.) or resources for where to
find success stories?
P2 opportunities could include water recovery or energy
reductions, increased reactor efficiency, methanol recovery
