]]>
i never thought of my hometown as a beacon of justice. i grew up in schuylkill county, pennsylvania, an area nestled in the northern appalachian mountains with a small town feel and conservative leanings. the county struggles with severe out-migration of youth, poor mental and physical health, and a lack of job diversity. after making a name for themselves in anthracite coal mining in the 19th century, the county transitioned to primarily manufacturing and distribution. to use the words of a fellow schuylkill county resident, we “put all our eggs in one basket” with this move from mining to distribution. i always wondered, what went wrong? was our violent, tumultuous past responsible for the lack of investment in the county in the present?  

during my final semester at the george washington university, i performed a community-engaged research project focused on my hometown to complete my sustainability minor. reflecting on my origins in schuylkill county, i wondered about its future. i knew that as climate change worsens, people will seek safety in higher elevations and appalachia will become a prime destination for thousands of americans. how could schuylkill county residents prepare for this demographic change? what role should they play in creating a sustainable future for this beautiful area? through my research, i found that lessons from our past could give me those answers.

i grew up hearing stories of the wrongful hangings of innocent men who advocated for themselves and condemned bigotry in their community. the true intentions of the molly maguires, a secret society named after an irish widow who protested against english landlords stealing land from the irish, are debated to this day. the mollies were persecuted for their extreme union activism and accused of terrorism in central pennsylvania. john kehoe, later dubbed the “king of the mollies,” moved to schuylkill county in 1868 to work in the coal mines amidst a wave of irish immigration to the area. kehoe’s confidence in this new world was squandered shortly after his work began. irish miners were given the worst shifts in the most dangerous conditions, paid less than a living wage, and constantly berated by their superiors.

in response to this injustice, kehoe and other irish miners formed a sect of the ancient order of hibernians (aoh), a benevolent, irish catholic fraternal organization originally founded to support irish people battling oppression. when their wages were cut by 10% to 20%, frustrated miners decided to strike, resulting in the long strike of 1875, which ultimately failed. miners went back to work, but their determination frightened the owners who sought to control them to make a profit. 

the reading railroad company president felt threatened by the aoh’s advocacy work, so he hired renowned detective allen pinkerton to investigate. pinkerton, believing that some aoh members were also active “mollies,” sent an operative named james mcparlan undercover to link the entire aoh organization to the allegedly violent molly maguires. mcparlan’s testimony, where he claimed that dozens of innocent men conspired to murder and rewarded members for murder, sullied the aoh name and devastated the strength of the organization. mcparlan’s stories helped sentence twenty men, including john kehoe, to death by hanging. from his cell, john kehoe wrote, “thinking over the cruelties that has befallen me, by bribery perjury and prejudice … i am under the sentence of death. for a crime i never committed which i will prove to you.” the hanging of the “mollies” in schuylkill county was an act drenched in social, religious, and ethnic bigotry. the aoh were champions of union activism and their work to empower thousands of miners should not be forgotten.

“how do you take those strengths of those people and turn it into something that is brave now?” jeanne elberfeld, a licensed social worker, asked me as i interviewed her for my research. i asked elberfeld and two other schuylkill county residents what they desired for the community in the coming decades –– and what they felt we had the potential to achieve.

elberfeld said she envisions a community where people live collaboratively and cooperatively with one another; a community that thrives because the residents are united in common goals and communal success –– not individual gain. elberfeld and other research participants, including regina gargano, stressed the importance of unity.  

gargano, executive director of the county’s tourism bureau, emphasized the significance of using the county’s past as a teacher. she said the younger generation needs to break cycles of poverty and lack of development by electing changemakers and ridding our community of economic plans that do not serve us.

gargano recognized that reviving schuylkill county would be a difficult process, but her hope was contagious. when asked what we have the potential to achieve, she said, “our people here are special and they know how to create what they need. it’s just a matter of building the consensus on what it is we really need to prioritize and breaking down the parochialism that stifles unity among us. if we could apply this to dismantling the current power structure of our economic and political leadership and unite in trying to diversify that economic development, there’s no reason to believe it could not eventually succeed.”

when asked what she hopes for the future of the county, jessi trusky, a 23-year-old schuylkill county resident, said inclusivity. she advocates for an environment where newcomers are welcomed and accepted and everyone gets an equal say in what happens in our community. i believe this sentiment will go a long way when the county eventually adapts to a demographic shift.

during my conversations with these women, i learned that our desires for our community are not so different from those of our ancestors. we all want the same thing: to grow together as a united, loving community where everyone looks out for each other. with this in mind, it’s important to reflect on the legacy of john kehoe and the union activists who lost their lives fighting for equality and allow their bravery to motivate us in molding a more prosperous and sustainable future.

to answer jeanne’s question –– “ how do we do this?” –– i think it is made possible by listening to and respecting one another. by giving voice to all members of the community and inviting young professionals to grow with us. one way to do this would be to repurpose abandoned coal mines and give them new life as solar energy sites, recycling centers, or underground farms. this change would encourage investment in sustainable technologies, create jobs, reduce blight, and attract outsiders to work in the area.

appalachia should not be a forgotten region. our community is strong, determined, creative, and hopeful. my hope for the future of schuylkill county is that the next generation sees the results of these characteristics in action.

house subcommittee looks toward the future of coal //www.getitdoneaz.com/story/coal-future-politics/ fri, 12 jul 2019 18:01:19 +0000 http://dpetrov.2create.studio/planet/wordpress/house-subcommittee-looks-toward-the-future-of-coal/ medill's noah broder reports from a house hearing, which looked at the value of coal to our economy. dems called for more environmental controls, while the gop stressed its importance to our energy infrastructure.

by noah broder

washington––democrats and republicans had opposing views on the value of coal to the u.s. economy thursday, with democrats calling for more environmental controls and republicans stressing how essential coal is to the energy infrastructure.

democrats at the house subcommittee on energy and mineral resources hearing worried that companies that mine on federal land are not paying their fair share, and that the environmental and social consequences of coal are not being properly considered.

republicans spoke about the success of the program in job creation and how indispensable coal is to the energy infrastructure of america.

the federal coal program is a bureau of land management program that allows private companies to mine coal on federal land. the companies bid for the rights to use the land and pay the government a fee for the land and the coal extracted and a royalty on the coal that is sold. the program is predominantly found in western states like wyoming and was integral in the powering of america throughout the 20th century.

now, critics say the program needs to be modernized and reformed to reflect the true cost of relying on this part of the fossil fuel industry.

subcommittee chair rep. alan lowenthal, d-calif., said the program “ignores the effects of coal on our climate and the future of americans who are losing their livelihoods as coal disappears. these are two things that i’m most focused on.”

but arizona rep. paul gosar, the top republican on the committee, stressed the importance of coal to the u.s. economy. “coal mining is essential to american energy security, providing an affordable, reliable source of baseload power to families across the country,” gosar said. “coal mining also employs over 53,000 people, including regions of the country experiencing economic hardships, like appalachia.”

the differences in focus laid out in gosar and lowenthal’s opening statements were present throughout the hearing. for the few democrats who were present during the hearing, like rep. jared huffman, d-calif., questions environmental and social problems related to mining and the industry. most of those questions were directed at jim stock, an economics professor at harvard and a member of former president barack obama’s council of economic advisors.

“in recent research, i and co-authors estimate that 92% of the decline in coal from 2008 to 2016 is due to the decline in natural gas prices,” stock said. he added that mine closings and consolidation “demonstrate that market forces are driving the decline of coal, despite the many pro-coal actions taken by (president donald trump’s) administration.”

for republicans, the focus was on questioning hal quinn, president and ceo of the national mining association. quinn echoed gosar and other republican’s views that coal is a job creator and a significant part of the country’s energy future. he called the federal coal program a “national and economic success story” and disagreed with the 2016 obama-era decision to place a moratorium on the program.

while the differences across the aisle were clear, lowenthal articulated the shared goal of wanting to learn more and properly address the coal program moving forward. “we could do this in the same haphazard way that we’ve managed the federal coal program over the past few decades,” he said. “or we can consider phasing out the federal coal program in a reasonable, thoughtful way that protects workers, guarantees mine cleanup, and addresses climate change.”

‘things that simply won’t let go’ //www.getitdoneaz.com/story/environmental-activist-hogan/ fri, 08 mar 2019 04:45:41 +0000 http://dpetrov.2create.studio/planet/wordpress/things-that-simply-wont-let-go/ judy hogan is an 81-year-old environmental activist and writer who has been fighting issues of environmental justice in chatham county, n.c. for decades, and is now taking on coal ash dumping with little community support.

]]>
judy hogan is an 81-year-old environmental activist, writer, and teacher. over the past few decades, she has fought a myriad of different environmental justice issues affecting her community in chatham county, n.c. right now, she is leading an effort against duke energy dumping and incinerating coal ash in her town. she publishes books and poetry and teaches writing classes twice a week as well.

this series is accompanied by selected poems from hogan’s most recently published book, called “shadows,” which is autobiographical about her daily life. i took a more free-form, artistic approach with this caption style because i want judy hogan to speak for herself: 

“for me it’s shadows. every day i walk across

the dam, i watch for my shadow marching

below me, down the hill, and some days,

when the wind is still, even across the water

and up the hill at the other end of the earthen

dam that creates jordan lake. in the painting

there is one small human figure surrounded

by rushing water, darkly threatening clouds,

with only a small window of blue that could

be sky but is probably water. that little

shadow is very persistent as she trudges

along. even in a wind, she doesn’t hesitate,

pulls her hood up to protect her neck and

ears. a step at a time a great distance can

prove possible. but, oh for the courage

to believe in that shadow. i like to think

that when i’m gone, and even if storm clouds

dominate, and water boils and foams, and

wind is cruel and relentless, that my shadow–

all that is left of me and whatever words

on paper survive my death–will keep on

walking with firm steps, seeing more than

i can see now, accepting storms, even

lightning, but refusing to be dismissed,

ignored, or turned aside–something eternal

or stubborn, or so part of the nature of

things that it simply won’t let go.”

 

“how to tell it? i have a new friend

in the midst of my aging, when new

friends are rare. she’s a bird-watcher.

i’m a people-watcher. what i learn,

i scarcely know until i put it in my

books. some mistrust other people

first and foremost. i attend to them

with my mind open. she talked to

my dog, and wag listened. wag is

tolerant now of other people but

skeptical, too. it takes time for her

to trust, but the bird-watcher turned

out to be a dog-whisperer and spoke

wag’s language, baffling to me. mind

over matter maybe. wag would stop,

hesitate, and then touch her nose to

the outstretched hand. me she pulled

in, too, to tell of the sixteen eagle

nests around our jordan lake. i

asked how they would have fared

during our hurricane. she said they

have favorite places to hunker down

during storms, but we had four days

of wind and rain, so she’s checking

on them. she watches for them to

fly by, way up there and catches

them in her camera the way she

caught wag and me as we walked

toward her, both smiling, she says.”

 

“erik erikson said ghandi found his

true identity when he was fifty. i

was seventy, still healthy, writing

and publishing books, teaching writers,

a small farmer with a flock of white

rock hens, and a leader in my

community. at eighty, i take that

diversity of tasks for granted. i don’t

debate. it is a balancing act, and

my balance ability is distressed

by my age. still, i rake and dig.

i hold onto tree branches and my

chain-link fence. i’ve said i’m

both penelope and odysseus. i

did have my once-in-a-lifetime

love–across the ocean, despite

the language barrier, and our

different lifestyles. we fought,

but we held on. he became one

of homer’s shades, reduced to

shadows in the underworld, but

still alive, still speaking and

foretelling the planet’s future if

we don’t attend to the signs. i’ll

be a shade, too, before too many

years have passed. some of that

is beyond my control, and some

is up to me. the doctors urged

a cane four years ago, but i said

no. “i can’t farm with a cane.”

they said medicine, but i was

wary of the side-effects, the

medicine worse than the complaint.

my body heals while i sleep.

it puts me to sleep a lot. but my

aches and pains go away. i tell

them i have good telemeres.

they listen. the symptoms which

puzzled them have disappeared.

eighty isn’t so bad if you accept

that your pace will be slower…

no, i’m not a shade yet, and life

still pulls surprises out of my

lucky grab bag. i can’t complain.”

 

most thursday afternoons, hogan shops at a local farmers market in pittsboro, n.c., and passes out poems that she has written to the farmers.

“i was afraid my heart would rebel

and keep me from leading a workshop

on writing poetry. my friend had said

to rest more. i had things to do,

but i did stop to rest. then six people

came to learn what i knew about

poetry. “what is a poem?” i asked.

they suggested it was condensed

words, that it was like a stream running

through the soul. i told them the

fourth grader’s understanding: “a poet

is someone who writes poetry, someone

who loves all living things.” i told

them about homer’s muse, about

the old testament prophets who

cried: “the word of the lord came

to me.” about how words could seem

to take off, and the deeper mind to

throw up words we weren’t expecting.

i mentioned jacques maritain’s hexis–

a gift we have in our unconscious

that we need to take care of and

listen to. if the poem starts in the

grocery store, make more room

in your life for the muse. then i

asked them to write a simple poem,

and they all did, even the librarian.

to my surprise, they all read their

new poems. they trusted me and

each other enough on very short

acquaintance. my heart behaved and

was quieted. another unexpected gift.”

 

hogan has often felt threatened and disliked by people who don’t agree with her vocal writing and environmental activism.

“some see the world as a dangerous place.

i don’t. one says, “you see it as a safe place.”

i say, “no, but i see it differently. i know

there are dangers, but i’m focused on trying

to be in tune with the grain of the universe,

with the way it’s made. i follow my deep

intuition, even when it doesn’t make sense.

it makes me accident-unlikely. i may have

accidents, but usually they’re not as bad as

they could have been. so, yes, i had that flat

tire on thursday, but it happened in my

front yard. i drove it across the road and

turned. when it was still bad, i pulled over

and stopped to look. i had a very flat right

front tire. or i have car trouble as i pull into

a service station. i work toward peace

with my neighbors and fight for all of us

for cleaner air and water. they respect me

and protect me. i’ve never been harmed

by my neighbors, and i’ve often been

helped. you don’t need to worry about them

harming me.” i have a very different

orientation to the world. there are dangers

and evil people. if people are determined

to be my enemy, i stay away from them.

in the meantime, i try to have friendly

relations with everyone, if it’s possible. i’m

outspoken, and some people hate what i say

and can’t forgive me. one day i might be

harmed, but this way to live suits me.”

 

“resting is hard for me. i have so much

i want to do before shadows take me

from this life. maybe

i don’t need to be so inactive. can

i let go fear, slow myself down but

not stop, not let fear put its claws

into my soul, my trust that, if i pay

attention, all will be well.”

 

hogan usually wakes up around 4 am every morning, always starting her day by spending a few hours writing in her diary and adding to whatever book she is working on.

“beginnings are hardest. in the morning

i sit up slowly, inch my way closer

to a place to hold on, rise carefully,

balance before i walk. i make sure i don’t

go too long without eating and sleep early.

as the day waxes, my confidence returns.

i remember what i need to, see to the hens,

make notes in my diary, in which i tell

the whole story. sometimes i start to fall,

but i catch myself. at the dam i walk

steadily, don’t fear falling. back at

home i’m warmer, shed layers, resume

morning tasks and rituals, with enough

energy for the day. by myself i see the

years of faithful work to leave my legacy

of stories and insights alive behind me.

among others i see their discomfort.

they don’t look at me. they forget

my place in the line-up of poets. i make

them nervous. why? maybe because

i look into death’s face and am not

afraid. how does one find that

particular courage? it arrives in time

to be useful in the last years, but i

realize i’ve practiced going my own way

most of my life, since age twenty-one,

to nearly eighty-one. not dismissing

urgencies that would keep me whole

and safe, not denying love when it

defied logic. those who hated me? i

stayed away, and generally, they did, too.

i sometimes lose things or forget them,

but i’ve never forgotten to safeguard

my soul and keep it whole, no matter

what my circumstances are.”

 

“proust thought time destroyed us,

those hidden memories our only

salvation. for me, time allows

fulfillment, to come into my own,

to learn, to heal, and even to be

recognized and valued. there were

people who hated me, but they

didn’t stop me. my own body

slowed me down, reminded me

i had done well and to think of those

i love. i persuaded my friends

and my doctor to trust my way

of life, my faith in myself; to let

me continue my independent way.

my son and i learned to live

together. we lost some crops,

but harvested bushels of tomatoes.

i made spaghetti sauce and soup.

now there are grapes to make

muscadine jelly, pears to make

preserves. i do my work as a

writer, editor, teacher. i celebrate

jaki, whom i first published

forty-five years ago. i will

teach poetry and story writing.

like the moon’s slow, steady

increase of its light, i resume

my own life of work and love.”

hogan has poems about birds written in word magnets on her fridge.

“i slowed down, did easy work, nothing

strenuous. the hurricane left us to mop

up and dry out. sun came back, the better

to see the devastation. here, where we

escaped the worst, life was almost normal

despite rivers that flowed upstream, the

milk we couldn’t buy, the flooded roads

we couldn’t pass. i wanted more work.

i made a list i’m crossing off. something

in me wants serious work, to tell some

story more than poetry tells or my

diary. a new book then about aging

and adapting. there is more to tell

than i have admitted so far. at eighty-one,

how many women tell what it’s like,

to lose the capabilities we always assumed,

to have gates closed, but the mind still

open, still able to articulate paradox

and justice, when everything in the human

being or in the state works easily and

smoothly together, each part doing its

own work? mine has been to write, tell

my mind’s story. i’ve written many books,

but there is still more to tell. i will.”

 

hogan leads a community meeting once a month to plan next steps in the area’s continual fight against the presence of coal ash in chatham county, n.c.

“how do i describe my faithfulness to my

deepest knowledge, to what i see but

can’t easily reveal in words. i tried not

to be good as a child is good. i rebelled

against old formulas, trite words. i loved

thoreau’s wisdom: “if i see someone

coming to do me good, i run for my life.”

i rejected that impulse to “do good.” yet i

have always worked against evil when

i saw it blazing up in corporations, in

those fearful of rocking the boat, or who

were terrified to be seen as bad, as trouble-

makers. so i’ve been castigated, dismissed,

written off. it hasn’t been so bad. some

tender hearts have loved me, and even

tough-spirited strangers have helped me

out. i have a few fans of my books. i

don’t need acclaim, but i do need to feel

loved and acknowledged by those i love

and trust, those who can see with clear

eyes who i am, what i care about. i’ve

been told many times that what i want

is impossible, will never happen. they

say life isn’t like that. you don’t get what

you wish for. in short, the power of evil

is too great. i don’t give up, however,

and then people love me. things begin

to change. what my skeptics have

forgotten is the power of transformation

and what love can do when it’s unleashed,

when we see clearly, when other people’s

minds open like a book that wants to be

read. i can’t make that happen. i can’t

stop it. i can, however, give it my

gratitude and let it go to work.”

 

judy hogan waits for people to show up at her community coal ash meeting on oct. 5, 2018.  one community member and a professor from unc chapel hill doing research on water quality in chatham attended.  since hogan first started working against coal ash in 2014, interest and support from community members for the cause has severely dropped off.

“milosz helped me see, at age

eighty-one, that our worship of science

and technology, our allowing a dictator

to be elected president, is killing us off.

the big electricity corporation has brought

us a present we couldn’t refuse of seven

million tons of poison. they say they’ll stop

now. they’ve done enough damage. instead,

they’ll burn the coal ash again and kill us

faster. no one stops them. people are

getting sick. they don’t want to fight

any more. they forget: when we fight, we

love each other. we can live with our

differences. black, white, and hispanic;

church-goers and non-church-goers.

andrew says, “you’ve won a victory.

have a victory party.” rhonda says,

“you’re defying the doctors. i predict

you’ll have a stroke.” she’s angry at her

body’s weakness, and at me, for trusting

myself and challenging doctors, our techno-

masters in a sickening world. the human

body knows how to heal itself. instead, they

give us pills and then more pills, and the

body then is truly sick, won’t fight any more.

milosz lived under the nazis, under stalin.

he fought and he survived. i, too, am

fighting, and i, too, am surviving. love

can conquer. give it a try.”

 

“even love has its misunderstandings.

sometimes my son and i knock heads.

we’ve learned to let go when arguments

go nowhere. everyone has her own world

view, her own life story, fears, and dread.

agony is human, but so is joy. we watch

the exultant eagles join the circling vultures.

for one, it’s work-related, for another, it’s

ecstatic. when our hopes and desires

merge, worry disappears. when pain

returns, we are constrained to work free.

i write my troubles down, the better to let

them go. when they reappear, i’m

prepared. we all learn as fast as we can,

which means some more slowly than others.

a lot depends on our heritage and even

more on work we’ve already done to cope

when people hated us, when our loved ones

turned their faces away. the late years

lead to a homecoming or some call it a

home-going. we have some say-so. for

me, there are many rewards in this last

stage, which erik erikson called “ego

integrity versus despair.” we find rewards

for our self-defense, our ability to listen

and give a helping hand. people we

scarcely knew turn up to help us. a young

woman wants to study me for clues to

living a benign life as a freedom-fighter.

another woman in her middle years is

drawn to my relaxed humor. most terrible

things draw our tears, but some that can

wrench us later make us laugh. my

doctor, as i eluded the medicines and

survived, calls me trouble, but she’s

smiling. another older woman says we’re

both eccentric, but a good eccentric. my

son is learning to protect garden spiders,

cherish poetry, and love my homemade bread.

i still walk without a cane, urged upon me five

years ago. some work i’ve let go. i rest more,

but i do all i can do–gratefully. look around:

i have students and friends. i’m cherished by

those i want to cherish me. i’m alive and writing

down what my last years are like. already i

inherit that persistence i foresee in my shadow

after i’m gone. she’ll be okay.”

the main objective of this study was to develop a novel flowsheet for extracting valuable metal oxides from coal ash wastes and to develop a suitable process to utilize them as a useful product in the form of a cement-less concrete. we used totally waste materials to produce some useful metals and also cement-less concrete with much less carbon footprint. we not only left nothing behind as waste but also helped the climate and prevented global warming by decreasing carbon dioxide production.

mn2020: policy attacks on minnesota waterways //www.getitdoneaz.com/story/mn2020-policy-attacks-on-minnesota-waterways/ sat, 04 aug 2012 07:00:52 +0000 http://dpetrov.2create.studio/planet/wordpress/mn2020-policy-attacks-on-minnesota-waterways/ recent federal policy proposals could seriously impact wildness areas around the nation, including minnesota’s boundary waters canoe area wilderness.
environment minnesota has released a new report detailing impacts that could result from expanding development and mining projects in the name of short-term job creation, all while bypassing critical natural protection policy in place.
it’s time creating jobs by prioritizing the sustainabile energy economy instead of slashing environmental protections for short-term gains.

making coal fired generators more efficient and less polluting with hydrogen //www.getitdoneaz.com/story/making-coal-fired-generators-more-efficient-and-less-polluting-with-hydrogen/ sat, 12 may 2012 15:08:46 +0000 http://dpetrov.2create.studio/planet/wordpress/making-coal-fired-generators-more-efficient-and-less-polluting-with-hydrogen/ presently, coal is ground to a powder then sprayed into a furnace for more even and complete combustion that heats water to steam and steam to super heated steam. the expansion of steam to super heated steam operates the turbine generating electricity.

the super heated steam then must be cooled to steam by evaporating water. this requires volumes of water evaporating into the atmosphere. then the cycle is repeated to super heat the steam to forcefully expand and operate the turbine.
the coal emissions of carbon dioxide, sulfur dioxide, nitric oxide, hydrochloric acid, and hydroflouric acid are related to the volume and type of coal burned. one pound of coal produces approximately the same btu of one gram of hydrogen without the coal emissions.

hydrogen can be made by spraying super heated steam over finely ground iron rust. this will yield hydrogen, cooled steam, and red paint pigment without sending large volumes of surface water into the atmosphere. the hydrogen produced is sprayed into the furnace as a second fuel with the powdered coal dust decreasing the amount of coal required to produce the btu to super heat the steam. (the ratio of coal dust to hydrogen is not known by this writer.) with hydrogen as an additional fuel in the furnace, the cooled steam is then reheated to super heated steam driving the turbine to produce electricity. the amount of coal burned to produce the electricity is decreased. the amount of coal emissions is reduced. the amount of the coal or natural gas fuel cost is decreased. i do not see any reason the same hydrogen boost cannot be used in natural gas fired electrical generators.

essentially, hydrogen is a byproduct of cooling super heated steam by a method other than evaporating water. the natural gas required to fire all of the existing coal fired electric generators would consume most of not all of us natural gas production. therefore use hydrogen to make the coal and natural gas electric generators more efficient.

oil-spill cleanup material: coal fly ash //www.getitdoneaz.com/story/oil-spill-cleanup-material-coal-fly-ash/ mon, 19 dec 2011 10:39:19 +0000 http://dpetrov.2create.studio/planet/wordpress/oil-spill-cleanup-material-coal-fly-ash/ a team of undergraduate and graduate students at the university of central florida is transforming fly ash–a waste product from coal-fired power plants–into an environmentally friendly adsorbent for oil-spill cleanup.

researchers hope this material will be an economical alternative to current methods of soaking up oil at clean-up sites. at the same time, it could potentially reduce the amount of fly-ash waste in landfills.

tens of millions of gallons of oil are spilled into the environment every year from human activities. at the same time, tens of millions of tons of fly ash, a byproduct of coal combustion, are disposed of in landfills. fly ash, consisting of tiny spherical ceramic particles, is a poor oil sorbent. the researchers have found a simple chemical process that transforms these smooth billiard-ball-like particles into a highly porous, nanostructured material that repels water and soaks up oil. once saturated with oil, the powder can be recycled back to power plants as fuel.

scientists urge carbon capture and storage for coal power plants //www.getitdoneaz.com/story/scientists-urge-carbon-capture-and-storage-for-coal-power-plants/ fri, 05 aug 2011 11:30:53 +0000 http://dpetrov.2create.studio/planet/wordpress/scientists-urge-carbon-capture-and-storage-for-coal-power-plants/ every year about 30 billion metric tons of carbon dioxide is released around the world, with almost half that amount coming from coal. in the u.s., coal provides almost half our electricity, making it tough to simply stop burning it. but what if we could capture carbon dioxide from the smokestacks of power plants?

energynow! correspondent dan goldstein explored how innovative carbon capture and storage, or ccs, technologies could keep carbon dioxide out of the atmosphere and help prevent the climate from changing.

“the same types of materials that are used in shampoo and conditioners were materials that we thought we could use in this particular instance to capture carbon,” said bob perry, a chemist with general electric. “with the co2 we’ve captured, we now have it in a confined space and can move that toward someplace for storage, for sequestration.”

ccs may be key to reducing carbon emissions, but installing it on america’s coal-fired power plants won’t be cheap. “the consumer is going to see an increase in the cost of electricity of 5 to 10 cents per kilowatt hour,” said gary rochelle, a chemical engineer at the university of texas in austin who has developed a technology to raise carbon dioxide out of power plant smokestack emissions. “that’s a 50 to 100 percent increase in what they’ll be paying for electricity.”
