power of produce

SOUTH
DENNIS — A South Dennis market is taking the term
"greengrocer" to new heights.
Rings Bros. Marketplace, which features a small grocery store, deli,
fish market and pizzeria under one roof, produces as much as 130 tons
of organic waste a year. The cost to dispose of all those food
trimmings, vegetable scraps and wilted flowers runs about $80 to $100 a
ton.
But with the help of a $195,000 grant from the Massachusetts Technology
Collaborative's Renewable Energy Trust and a small company in Boston,
Ring Bros. hopes to recycle garbage into electricity and create organic
compost at the same time.
Like many grocery stores, large and small, Ring Bros. pays someone else
to haul away tons of food waste every year. It's not a cheap
proposition. And like so many other grocery stores, the amount of
disposable waste Ring Bros. produces includes a large percentage of
organic waste — easily 100 tons annually.
Patrick Ring, son of the store owner, hopes to begin using that garbage
to produce electricity to power not only his store, but also adjacent
businesses. The money from the renewable energy grant will be used to
develop an on-site system that will recycle organic waste, producing
both high-grade organic compost and gas capable of powering a turbine,
which in turn will produce electricity.
The design, testing and installation of the system could take a year or
more.
"It's an economic decision, a long-term investment in cutting our costs
and being environmentally responsible," Ring said.
Major sources
of waste
According to the state Department of Environmental Protection, grocery
stores are a major producer of food waste in the state. The 400 or so
large grocery stores in Massachusetts produce an estimated 90,600 tons
of organic waste material each year, according to a department
spokesman.
Of this, an estimated 20,784 tons are now composted or shipped to pig
farms. The rest is carted away by commercial haulers and often ends up
at municipal landfills. Ring said he does not know exactly where the
waste from his store ends up, but thinks it is probably the Dennis
landfill.
"Anything we can do to cut down on the cost of getting rid of waste and
help the environment in the process is a good thing," said Donald
Fallon, general manager and director of marketing at the South Dennis
business.
In addition to the garbage disposal cost, Ring estimates the store
spends between $25,000 and $30,000 a year on electricity. Being able to
generate its own electricity would be a real plus for the store, he
said.
"Like any business, we are always looking for ways to cut costs," Ring
said. "Don and I work all the time on ways to make the business more
efficient. Operating costs is naturally a place you look."
Fallon added: "In our business, electricity is a big bill. There are
lots of coolers to run. Last year we installed a system that enables us
— in winter — to use cold air from outdoors to keep
the
temperature down in the coolers. We installed more energy-efficient
light bulbs in the store. We're always looking for new ways to improve
how we run the business."
Help from a
friend
What
Ring wants is an on-site facility that produces not only compost, but
also energy.
The potential for generating surplus energy is there, but could take a
while to develop for smaller-scale operations like Ring Bros. Enter
Shane Eten, founder of Feed Resource Recovery and a childhood friend of
Ring's. His Boston-based company will design and develop the system for
the South Dennis store.
Eten and his wife, Kimberlee, founded the company, which is now run
with partners Ryan Begin and Nick Whitman. Eten met them while studying
business in graduate school at Babson College in Wellesley.
"I think my interest in alternative energy and renewable energy may
have been prompted by my father's frequent and not very successful
experiments trying to heat our pool with solar energy," Eten said of
his childhood home in Brewster.
While not wanting to give away too many details about the system he
will develop for Ring Bros., Eten said: "We're excited about this. It
is a real opportunity for my partners and me, and for businesses like
Ring Bros. Our hope is to see increasing number of businesses tap into
this sort of thing."
Ring is optimistic that the technology being developed for his business
could be expanded for use in other businesses that produce food waste.
"Getting a system that enables us, a small business, to do this on
site, and eventually produce energy, will be a huge thing," he said.
"It could lead to other small businesses or perhaps consortiums of
small businesses developing similar programs. Imagine if restaurants on
the Cape had a means of putting their food waste to productive use."

SIDEBAR
Organic
savings
Two years ago the state and major supermarket chains began working
together to increase recycling efforts - particularly to encourage
composting such items as spoiled fruits and vegetables, floral and deli
wastes and waxed cardboard, according to Brian Houghton, vice president
at the Massachusetts Food Association, which represents 95 percent of
the food sellers in the state, including large chains such as Whole
Foods, Stop & Shop, and Shaw's. Ring Bros. does not belong to
the
association.
• Stores participating in that
concerted
recycling effort began reporting savings within a year, according to
figures from the state Department of Environmental Protection.
• A pilot program at Roche Bros.
Supermarkets,
which included 12 of the chain's stores, was projected to save $10,000
to $20,000 per store.
• Most grocery stores
participating in the
state-private enterprise to recycle are still having their organic
waste shipped off site for conversion into pig food or compost.
• Hannaford Bros., a Maine-based
chain of
supermarkets, has begun a large composting program at its Nashua, N.H.,
store. Behind the store is a tractor-trailer-size contraption that
functions as a supersize garbage compactor making compost out of
organic garbage - compost later sold to farmers.
