Maine companies look to biochar as a climate solution, to capture carbon and improve soil health


In a former biomass plant in Greenville, wood chips are flowing from hoppers into long tubes about three feet in diameter.

Pat Jones is the president of Clean Maine Carbon, which burns wood in high-temperature, low-oxygen conditions known as pyrolysis.

“It starts out as wood” he said. “And as you can see when we come over here what comes out the other end is biochar.”

In the quest for climate solutions, Jones is among the Maine entrepreneurs banking on this charcoal-like substance. They say it can bind up carbon for decades, and improve agricultural soils at the same time.

The end product has high carbon density, and is very stable, so less of the carbon will be released into the atmosphere than if it were left to decompose. So while Jones is making biochar, his business plan is focused on selling carbon credits to corporations.

“So somebody will say, ‘Would you like to sell credits to XYZ company?’ And we’ll say, ‘Yeah, what’s the price?’ They will pay on a per-ton basis, whatever the agreed value, based on carbon content and everything else,” Jones said. “And that’s the end of it, they never get the biochar and they don’t do anything. They get to use those credits to help reduce their footprint, their carbon footprint.”

Most of the biochar Jones has sold from the Greenville plant has been for agricultural applications. And he’s not yet certified to sell carbon credits, but pending the completion of an audit, he said he’ll be able to sell credits even on the biochar he’s already shipped.

Scientists and advocates debate the true value of carbon sequestration as a response to climate change. Jonathan Foley is executive director of Project Drawdown, a nonprofit that focuses on science-based climate solutions.

Foley says 95% of climate solutions should focus on reducing emissions by driving more efficient cars, for example, or insulating houses. But he said there’s also value in removing carbon from the atmosphere. And while there’s no silver bullet, biochar could be seen as a piece of silver buckshot.

“And we can put that in farm fields, we can bury it in old mines, we can bury it in the ground, and it should last for hundreds, if not thousand of years under the right circumstances,” Foley said. “So it’s a pretty clever kind of hybrid of nature and some engineering that might be a pretty good little piece of silver buckshot.”

And researchers are looking for ways to put biochar to use. As a soil additive, for example. University of Maine associate professor YongJiang “John” Zhang said the physical structure of biochar allows it to hold water like a sponge during periods of heavy precipitation, and release it slowly. It can also hold nutrients, and Zhang said these qualities can be beneficial when applied to the sandy soils of blueberry barrens.

“But if you have the biochar, it can hold more water, and hold the nutrients to increase the water use efficiency, and nutrient use efficiency,” he said.

Zhang said other research is looking at biochar’s benefits to potato crops, and its ability to lock up particles of PFAS in contaminated fields and prevent them from being taken up by plants.

Jones said he plans to produce about 1,200 tons of biochar annually with the current setup. But he’d like to scale up, using more and bigger equipment, to create more biochar and also put the excess heat from the process to work.

“So that it becomes more economical and practical to extract hot air and hot gasses for lumber drying for power generation, any number of things that could be done with this very clean, high-temperature gas,” he said.

Meanwhile, a second biochar facility, Standard Biocarbon in Enfield, hopes to start production in the next few months, and aims to produce about 1,200 tons annually.

Elementary-aged student killed in school bus crash in southern Maine

Elementary-aged student killed in school bus crash in southern Maine


A student was killed in a crash involving a school bus in southern Maine on Tuesday morning, officials say.

The crash occurred around 7:30 a.m. near Edna Libby Elementary School in Standish, authorities said, and MSAD 6 School Superintendent Clay Gleason told News Center Maine it involved a student and a school bus.

Cumberland County Sheriff Kevin Joyce confirmed that an elementary school student was struck by an MSAD 6 school bus and died at the scene. He said Route 35 was shut down between Route 114 and Moody Road for the crash investigation.

MSAD 6 serves the towns of Buxton, Hollis, Limington, Standish, and Frye Island. Standish is a town with about 11,000 residents about 15 miles west of Portland.

The child who died was a student at Edna Libby Elementary School, the school district said. Joyce said only one student was on the bus at the time of the crash — the half-brother of the student who was killed.

“The Cumberland County Sheriff’s Office, along with other law enforcement agencies, will be reconstructing the accident, providing more information as we get it,” Joyce said. “What we do know now is we have a child that’s deceased. It’s tough anytime of the year, but not a good time of the year for a lot of families.”

Gleason said Edna Libby Elementary School planned to dismiss students at 11:30 a.m. to allow parents or caregivers to be with their children and for staff to receive support. All after school activities in the district were canceled, though the school day went on as scheduled in all other district schools.

“I have been in communication with the Cumberland County Sheriff’s Office and a full investigation will be forthcoming to determine how this tragic accident took place,” Gleason said in a message to the school community. “In this difficult time please keep those directly impacted in your thoughts – first and foremost the family of the student, as well as the students and staff of Edna Libby. Speculation or blame on social media is not productive or helpful and is disrespectful to the memory of the student and their family.”

Support services are being provided for the bus driver and the family, Joyce said.

No additional information has been released, but officials said they expect to have more to say later in the day.

Maine Jewish community mourning, on edge after attack in Australia


PORTLAND (WGME) — The Maine Jewish community says the attack in Australia has left them mourning and on edge.

It comes amid an increase in antisemitic rhetoric, online and in our communities.

Members of Maine’s Jewish community say they have no choice but to take these increased threats seriously, especially in wake of the tragedy in Australia.

They are now increasing security, like during the menorah lighting for the first night of Hanukkah outside Portland City Hall Sunday.

The Jewish Community Alliance of Southern Maine says they’ve been coordinating with local law enforcement across the state since Sunday about heightened threat levels.

They say the attack in Australia is just the culmination of an increase in antisemitic actions that have been seen across the world in recent years, which Maine has not been isolated from.

“There were about, almost 16 antisemitic incidents, documented antisemitic incidents in 2024,” Jewish Community Relations Council Director Zach Schwartz said. “That represents the same increase that Sydney saw, which is a three-fold increase, so yeah, we could say by the numbers, that there is multiple orders of increased antisemitism in the state.”

The alliance says the story of Hanukkah is also more relevant than ever amid these attacks.

They say amid dark days, the Jewish community still finds ways to come together in hopes of lighting the way for a brighter future.

Governor Janet Mills issued a statement on both the shooting in Australia and at Brown University.

“My prayers are with the victims of the tragedies in Providence and Australia, and I hope for the full recovery of all those injured. Innocent people, like those gathering for school or to celebrate their faith, should be free from fear of hateful acts such as these.”
