We also helped an automotive solvent recycling facility in Among other things: ·
we were able to recover additional
solvent from the still exhausts and still bottom vapors. This decreased indoor
VOC concentrations and hence allowed us to reduce the general building exhaust
rate while still achieving an improved breathing zone ·
we were able to recover additional
saleable product from their solvent dehumidification byproduct stream ·
we identified opportunities to
decrease the energy intensity of their solvent distillation process Regards Bruce Bruce Taylor, P.Eng President Enviro-Stewards Inc N3B 3J9 Phone: (519) 578-5100 Fax: (519) 669-5002 www.enviro-stewards.com -----Original Message----- Enviro-Stewards helped a client of the Toronto Region Sustainability
Program significantly reduce its footprint while saving bags of money. See the description: http://www.oceta.on.ca/TORSUS/ProkleenOakville.pdf Note: this client after implementing the P2 measures was successful in
attracting new business from a company that wanted to be associated with clean! Fred Granek -----Original Message----- From: owner-p2tech@great-lakes.net on behalf of Nancy Larson Sent: Thu 9/13/2007 4:52 PM To: p2tech@great-lakes.net; 'This is a mailing list for P2
providers in Region 7' Cc: Subject: P2 for solvent reuse and recylcing business Greetings: I am working with a client trying to identify opportunities for solvent
P2 at his business that is in business to collect used solvent (as a
material) then reuse it to clean drums, distill it and then sell the solvent back
to clients. A continuous-use type of process. I have recommended a few things which are actually contrary to what
they want to achieve at their business and wonder if any of you had
additional ideas. Here is what I have suggested so far - Think about how you can * Change the Process, (use less
solvent to clean drums, train employees and clients, develop an job description) * Change the Technology, (
distillation efficiency, waste-to-energy unit like a burner) * Change the material to minimize
your waste. (Less toxic solvents - offer a line of acetone or alcohols to your clients and keep them
separate from other blends that contain halogens. Maybe a percentage of
your clients would prefer this less toxic cleaner.) EPA has a nice document at several locations including: EPA guidance to HWM plans: http://gcisolutions.com/HWFN0993.htm This is a comprehensive guide to minimization published in 2000: http://www.epa.gov/sbo/pdfs/hazwaste_500.pdf This one speaks to distillation and energy recovery: http://www.epa.gov/epaoswer/general/manag-hw/e00-001d.pdf We have a number of documents at http://www.sbeap.org/publications.php?media=Waste,Pollution%20Prevention,Env iromental%20Management%20Systems Other ideas?
