    Advice needed : Boil vent, aroma

    I'm starting a 2 - 3.5 BBL nano. Leased the "perfect" commercial space, ex-pizza shop with propane rail, vent hood, replacement air, and fire suppression (although I've already begun to question direct-fire). It's in a busy commercial/residential town center with several restaurants (many of the buildings, including mine, have commercial on the ground level and apartments above).

    An abutter expressed concerns over "brewery stench", presenting multiple internet articles about how the brewing process smells like rotten eggs or cow manure (uugh). While the town board doesn't expect that to be the case, they've still asked me to find "an odor reducing element" to incorporate into the system. They also asked me to show examples of functioning craft brewery's solutions to odor management.

    I've searched this forum and found only a suggestion to use a condenser stack. I mentioned this option to the town board, but they seemed to prefer an activated carbon filtration system or equiv. Does the condenser significantly reduce vent emissions?

    I'm self-financing on a very tight budget, so hiring an engineer to present a study is not an option.
    Does anyone know of reference material or articles? Or have any advice??

    Thanks in advance

    Everything I read in some brief research indicates that bad smells from breweries are related to waste water treatment. Can you post any links from the complainer?

    Bad smelling breweries are dirty breweries. Don't be a dirty brewery and you and the neighbors will be fine. Find a farmer to get rid of grain daily, clean your floor drains, don't let mold grow all over the place. Don't be a dirty brewery.

    Exactly. And the zoning board members caught that his articles were based on large commercial breweries with onsite waste water treatment. His other articles referred to spent grains as "sticky, smelly mush" like rotting oatmeal. I brought a zip-lock to show them spent grains after mash and drain. They didn't bother to view it. They don't believe his claims, but the burden is on me to prove that his concerns have been adequately addressed. I will present multiple examples of local breweries using roof vent systems with no neighbor issues (hopefully I can get some brewers and/or their neighbors to write statements of such).

    Again, exactly! The zoning board is hoping that I could find a low-cost odor control solution being used by other brewers... something that would squelch this noisy neighbor. But I can't find a common solution to an uncommon issue.
