RE: Question about P2 for maple syrup processors



Yeah, but isn’t it the "sugar water" that's the product, not the waste. The membrane lets the little H20 molecules through but holds back the big sugar molecules as the syrup.  This is a case where the filtrate is the product.  There shouldn't be any sugar in the "waste water" or at least not enough to economically ferment into alcohol.  Actually, it begs the question of what else is retained by the membrane that becomes part of the syrup?  Maybe just the rodent hairs and larger insect parts!

Here is one company that takes various products and converts them to ethanol:

They have several locations across the country.

Mike -

 

That's a sticky problem you've got there....

 

I cannot recall the name of the firm but a few years back I spoke at a

P2 workshop for food processors, conducted by SC Edison in ag regions of

southern california.  One of the other speakers was from a company that

bought and processed all sorts of sugar-bearing aqueous waste streams,

which they would then process into fermentable feedstocks and use to

produce ethanol and/or citric acid.

 

I apologize for not remembering the name of the firm -- I do recall that

they were located in Orange County, CA -- but I mention it because it

leads me to believe that the business model has probably been replicated

in other regions.  I tried a quick Google search to find similar firms

but came up empty, but a call to your local cider mill or juice plant,

inquiring about what they do with their off-spec product, might provide

good leads.

 

Hmmmm...what else?  Maple syrup wine?  Could be the next big thing...the

world needs a good breakfast wine that goes with waffles.

 

As far as other p2 strategies, you might want to review the ChemAlliance

virtual plant tour

(http://www.chemalliance.org/Handbook/plant/index.asp) and review the

case studies related to the terms "viscous" and/or "heat exchange" (to

name a few).  While the case studies deal almost exclusively with

chemical processing, the unit operations are quite similar and you may

find some inspiration from how others have dealt with the problems

inherent in heating highly viscous liquids (reducing delta T driving

force; improving mixing at the boundary layer, e.g. by scraped surface

heat exchange; reducing adherence of materials by surface modification

e.g., teflon or similar coatings). 

 

Hope this helps, even a little.

Subject: Question about P2 for maple syrup processors

 

Good morning P2Techers!

 

Mike Reele from Erie County, NY sent the question to the GLRPPR Help

Desk.

I've searched everywhere I can think of and not found anything. I'm

hoping that someone out there has worked with companies in this sector

and can give him some guidance.

 

Please reply directly to him or make sure to copy him on your reply

because he's not on P2Tech.

 

Here's the question, along with his contact information:

 

>First Name:             Mike

>Last Name:                      Reele

>Occupation                      Government

>State:                          OH

>E-mail:                         reelem@erie.gov

>Phone:                          716 858-8006

>Subject or Topic:       Are there any markets for the water produced by

 

>separating it from maple tree sap using a reverse osmosis process? 

>Also are there any P2 guidance info for maple syrup processors?

 

Thanks in advance! I hope everyone enjoys the long weekend.

 

Laura B.
