Disheartened

While observing Fox News, it was disheartening to see what their viewers were subjected to. It seems the Republicans’ far right wing extremists are conveying their idealistic visions against various nationalities, social diversities or political beliefs with an absence of emotion concerning women’s health issues, children’s rights, voter suppression, Seniors, Social Security, Medicare and Medicaid...

Things That Matter

All of us in small towns and large not only have the right to speak on behalf of our neighbors and ourselves, we have the duty and responsibility to do so -- and 238 years ago, we made a clear Declaration to do just that...

An Anecdote Driven Mind

So, is Thomas Kachadurian now the Northern Express’ official resident ranter? His recent factfree, hard-hearted column suggests it. While others complain about the poor condition of Michigan’s roads and highways, he rants against those we employ to fix them...

No On Prop 1

Are we being conned? Are those urging us to say “yes” to supposedly ”revenue neutral” ballot proposal 1 on August 5 telling us all the pertinent facts? Proposal 1 would eliminate the personal property tax businesses pay to local governments, replacing its revenue with a share of Michigan’s 6 percent use tax paid by us all on out-of-state purchases, hotel accommodations, some equipment rentals, and telecommunications...

Fix VA Tragedy

The problems within the Veterans Administration identified under former President Bush continue to hinder the delivery of quality health care to the influx of physically wounded and emotionally damaged young men and women...

Women Take Note

I find an interesting link between the Supreme Court Hobby Lobby and the crisis on the southern border. Angry protesters shout at children to go home. These children are scared, tired, hungry and thirsty, sent to US prisons awaiting deportation to a country where they may very likely be killed...

The Smell of Money: Pumping gas from landfills

Harley Sachs - August 11th, 2005
Here in the U.P we used to call them
bear pits. They were the open garbage dumps where tourists occasionally would try to
put their kiddies on the backs of hungry
wild bears in the hopes of getting that great souvenir photo, sometimes with unhappy results.
Turns out that calling our dumps bear pits was a misnomer. The proper name for what are
now officially sanitary landfills is money pits. Not only can municipalities reap substantial rewards from tipping fees of $90 a ton,
but they can also mine those mountains
of trash for valuable gasses and turn them into electricity.
That’s what R.G. Engineering Company of Webberville, Michigan is doing for
their clients.
If a landfill is designed properly, that is. Lined first with a heavy plastic to prevent seepage into the ground water, all those goodies stay put, waiting to be harvested. In particular, what Jon Rabitoy, president of RPG, is after is trapped methane.
We’re all familiar with methane. It’s
the gas we generate ourselves after a meal
of bad chili or cauliflower. We don’t generate enough to utilize other than to light as
a bachelor party prank, but a sealed landfill has plenty.
It works like this: gas wells are sunk from 30 to 90 feet in the landfill and a gentle vacuum sucks out the methane. It is then run through a battery of converters. Usually four are set up, with three always running while a fourth gets routine maintenance.
According to a confidential report from Rabitoy’s company, “Neenah/Menasha, Wisconsin developed a landfill over a 10-year period. The landfill was filled, capped and a collection system was installed 18 months ago. Today the landfill generates and flares 1,000 ft3/min of landfill methane gas, where the gas temperature is 96 degrees F and is delivered at 1 psig pressure to the flare.”
The electricity generated by this system is incredibly cheap, 2 cents a kilowatt hour created from the landfill gas which costs half a cent per kilowatt hour to recover.
The electricity is then sold for 5.5 cents a kilowatt hour, and the project’s net revenue is estimated at $475,146, with a simple payback for the project of 9.25 years.
Other systems can recoup the initial costs in less time, 5.1 years. Even more rapid payback can be derived from animal waste.
My brother was once part owner of a pig farm where the noxious waste was turned into methane to provide energy. They generated enough electricity on the farm to provide all their energy needs. A feed lot may produce many tons of animal waste. Anyone who’s lived within nostril range of one of those can testify to the noxiousness of that, but the electricity generated from that animal waste can recoup the costs of the installation in little over a year.
The electricity these systems generate is sold to the electric grid to supplement power generated by conventional plants. No wonder a landfill can turn into a profit for a municipality! They can collect at both ends.
What’s clear is that waste products from feed lots and city landfills can put a significant dent in our need for energy. I suspect that the Keweenaw bears are disappointed to no longer have easy pickings at our garbage dump, but if we go the way of Neenah/Menasha and other municipalities we’ll not only get some extra income, but we’ll utilize some of those infamous greenhouse gasses. Oh, and turn the stink to cash. You never knew the smell of money had an odor like that.
