Biomass and Carbon Dioxide
Lying in the center of the table in the picture is this document:
Biomass carbon neutrality in the context of forest-based fuels and productsThe copy on the table is dated April 7, 2010; the online version is dated May 2010. It’s a powerpoint presentation that makes many good points, among them that coal doesn’t grow back, while trees do. So in theory it would be possible, by organizing harvesting of biomass over a region to make burning biomass for electricity carbon neutral.

The document comes right out and says:
At point of combustion, CO2 emissions per unit of energy produced are generally higher for biomass fuels than for fossil fuels.Continue reading
Hahira Teachers Learn Trees
About 25 teachers from Lowndes County schools were out at the Pine Grove Farm in Thursday identifying trees and looking at leaves.Maybe later they could even take the students out to the trees!It’s part of project learning tree, an environmental education program.
Renee Galloway says students don’t really get out of the classroom in language arts and reading, so she’s glad she’ll have new lessons to bring to her class.
“Hopefully, our teachers can take back the importance of the timber industry to Georgia’s economy to their classrooms,” said Joy Cowart, a Project Learning Tree facilitator.That’s one good lesson. Others might be the diversity of native forests and the economic and natural benefits of reforestation.
Effects of proposed biomass plants in Massachusetts
The animations add the demand for wood for 5 proposed biomass incinerators in Massachusetts to the current wood demand, which is mainly for lumber and cord wood. The animations demonstrate the land area in western and central Massachusetts that would be required to be logged to satisfy the total demand for these 5 plants which would add only about 1 percent to Massachusetts’ electrical generating capacity (see calculations below).
Quite a price for such a small percentage of electricity generation. Solar, wind, and wave could generate far more electricity, even in far northern Massachusetts.
And the animation above is a conservative projection. Follow the link for
…the extreme case where all forested land in central and western Massachusetts would be made available for biomass cutting – including rare species habitat, scenic landscapes, public “protected” land, and other protected open space. In this case, all forested land in central and western Massachusetts would be logged in only 16 years.
In Georgia, that would include places like Reed Bingham State Park.

Biomass Permit Expected Fortnightly
WIREGRASS POWER, LLC(VLCIA is the Valdosta-Lowndes County Industrial Authority. Brad Lofton is its executive director.)The project should be approved and issued an air quality operating permit in the next 14 days, according to Lofton. A power purchase agreement should also be complete by June 1, 2010. The VLCIA granted an eight month extension for the project to begin construction.
We know from previous reports that this wood and sewage sludge incinerator is expected to produce a maximum of 25 long-term jobs. Many questions were asked at the air quality hearing about particulates, CO2, mercury, and other pollutants. The answers ranged from “we don’t monitor that” to Continue reading
Impervious cover increase, Lowndes County
Where’s all this change coming from and going to?
The dark green is labeled “Evergreen Forest” and decreased from 31.81% in 1991 to 26.47% in 2005. Meanwhile, the light pink labeled “Low Intensity Urban” went from 5.37% to 8.57%. Other changes include the red “High Intensity Urban” slice going from 1.15% to 1.98%. But the biggest change is piney woods being paved over for urban sprawl.
Could this have some effect on flooding?

WCTV on Biomass
On April 28 Deneige Broom wrote, Proposed Plant Raises Air Quality Questions:
A Biomass plant could bring business and money to the area. But some want to be assured their health won’t suffer in the name of progress.Some good quotes in there:
Dr. Brad Bergstrom attended the hearing wants concrete answers.Continue reading“There’s not going to be anything in the permit that will say, you can only burn this much sewage sludge,” said Bergstrom. “The company plans to only burn a small percentage but once they get their permit, that could change.”
South Losing Trees
Out of seven of the most heavily forested nations on Earth, the United States experienced a greater percentage of forest loss from 2000 to 2005 than did any of the other countries, a study said Monday.But what part of the U.S.?
The one part of the contiguous USA that experienced the most forest loss was the Southeast, a large chunk of which lost more than 10% of its forest cover from 2000 to 2005, the year for which the most recent data were available.Compared to what? Continue reading
Biomass Air Quality Hearing Set
6:30 PM, 27 April 2010We’ve been waiting on this date for a while. EPD is going to send a press release to the VDT a few weeks in advance and post it on its own website, www.georgiaair.org. Assuming, of course, that the date and place don’t change again.

Why should you care? This plant proposes to burn sewage sludge, which can release numerous hazardous chemicals into the air. Here is Seth’s letter to the editor of the VDT of 21 Feb 2010: Continue reading
