Our Waterworks Conundrum
I’d like to offer some thoughts regarding Jim Olsztynski’s recent
column,
“Our Waterworks Conundrum” (
Supply
House Times, August 2009, page 48) which I read with great
interest. As you can imagine, InSinkErator pays close attention to the
challenges associated with wastewater collection and treatment infrastructure,
both in the U.S. and throughout the world, given that our major product — food
waste disposers — interacts directly with those systems. Therefore, it’s easy
to agree strongly with Jim Olsztynski’s primary thesis that the U.S. water,
sewer and treatment systems are in need of substantial reinvestment to restore,
maintain and upgrade these vital services.
His column noted two among the many possible methods for financing such
improvements.
Another possibility — already being pursued by the leading wastewater treatment
facilities — for promoting such investment and effectively managing operating
costs is to boost the production and use of biogas that harnesses the inherent
energy in liquid waste. The framework for pursuing such an opportunity requires
a shift in thinking from “wastewater” to “liquid resource,” with a treatment
facility’s “products” becoming clean water (suitable for reuse), biosolids (for
re-fertilizing agricultural soils), and energy (for reducing on-site heating
and electricity costs). Indeed, this sector also is beginning to promote
the goal of wastewater treatment plants — which are notorious energy consumers
— becoming energy self-sufficient over the next 20 years.
That’s where food scraps increasingly are recognized as a significant
opportunity. Whether delivered by trucks or through sewers after being
pulverized by food waste disposers, food scraps — averaging 70% water — are
known to be energy rich, enhancing both the quality of biosolids products and
boosting biogas production (with possible benefits in treating wastewater,
too).
To that end, InSinkErator recently collaborated with the Milwaukee Metropolitan
Sewerage District (MMSD) on a public education campaign that encourages its
customers in 27 communities to divert more of their food scraps via their
disposers. Similar campaigns and incentive programs are in place in more than a
dozen European cities that address policies that limit the landfilling of
organic waste.
Apart from the significant business opportunity infrastructure reinvestment
offers for the industry, thanks for promoting attention to this vital challenge
to our nation and localities.
