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.

TOPSFIELD, Maine — Jenna Stoddard is not sure where her son will spend his days when he starts preschool next fall.
Sending him to East Range II School would be convenient and continue a legacy. Stoddard lives just down the street and her husband graduated eighth grade there in 2007, one in a class of three. Topsfield’s population has dropped since then. The school now has five students, two teachers, few extracurricular activities and nobody trained to teach music, art, gym or health.
Stoddard’s son is too young for her to worry about that now. But the school may not be open by the time he is ready to go. Topsfield, a town of just 175 residents, will vote on whether to close the school on April 30. If it closes, the boy would likely be sent to preschool up to 30 minutes away in Princeton or Baileyville.
“That’s a pretty fair distance for a kid, a 4-year-old, who is now on a bus all by himself,” she said. “[If] school starts at [7:45 a.m.], what time is the bus picking 4-year-olds up here? And what time is he going to get home at?”
Topsfield is an extreme example of how an aging, shrinking population and rising property taxes are forcing Maine towns to make difficult choices about their community institutions. Just over a dozen people came to a Wednesday hearing on the idea of closing the school. The crowd was mostly in favor of it.
“It is emotional to close the school in a town,” Superintendent Amanda Belanger of the sprawling Eastern Maine Area School System said then. “But we do feel it’s in the best interest of the students in the town.”
Teacher Paula Johnson walked a reporter through the building, which is small by Maine standards but cavernous for its five students. It has four classrooms, a small library, and a gymnasium. There is also a cook and a custodian for the tiny school.
A hallway trophy case serves as a reminder of when the school was big enough to field basketball teams. Topsfield’s student population has never been large, but the school’s population has dropped dramatically over the past few years. It had 25 students in 2023, with many coming from nearby Vanceboro, which closed its own school in 2015.
As the student population dwindled, the cost of sending students to Topsfield climbed. With fewer students to defray the costs, Vanceboro officials realized they would be paying $23,000 per student by the last school year. So they opted to direct students to nearby Danforth, where tuition was only $11,000 per student.
East Range lost seven students from Vanceboro, bringing its enrollment below 10. Under Maine law, that means the district may offer students the option to go elsewhere. Parents of the remaining students in grades 5 through 8 took the option and sent their kids to Baileyville. This school began the year with eight students; three have since pulled out.
In Topsfield, Johnson teaches four of the remaining five, holding lessons for pre-K through second grade in one classroom. Another one down the short hallway is home base for the other teacher. She focuses on the school’s lone fourth grader and occasionally teaches one of Johnson’s first graders, who is learning at an advanced level.
The other teacher, who holds a special education certificate despite having no students with those needs, plans to leave at the end of the school year. If the school stays open, that will leave Johnson responsible for educating Topsfield’s youngest students, though the school will need to budget for a part-time special education teacher just in case.
After 11 years at the school, Johnson is not sure what she will do if voters shut it down.
“We’ll see what happens here,” she said.
Topsfield’s school board, which operates as a part of the Eastern Maine Area School System, is offering its residents a choice: continue funding the school only for students between preschool and second grade at an estimated cost of $434,000 next year or send all students elsewhere, which would cost less than $200,000.
At Wednesday’s hearing, the attendees leaned heavily toward the latter option. Deborah Mello said she moved from Rhode Island to Topsfield years ago to escape high taxes.
“It’s not feasible for the town of Topsfield,” she said. “We cannot afford it and it’s not like the children don’t have a school to go to.”
Others bemoaned the burden of legal requirements for the small district, including the need to provide special education teachers even if they don’t need one. Board members also mentioned that in 2028, the district will become responsible for educating 3-year-olds under a new state law. That adds another layer of uncertainty to future budgeting.
“It sounds like we’ve been burdened something severely by this program and that program by the Department of Education, to the point where a small school can’t even exist,” resident Alan Harriman said.
“And that’s been happening for a long time,” East Range board chair Peggy White responded.

BANGOR, Maine (WABI) – Good morning and Happy Sunday everyone. Skies are cloudy with fog across much of Maine this morning. Rain has entered locations along the interstate and to the northwest. Temperatures vary from the upper 30s to mid 40s. Winds are out of the SE between about 5-15 mph.
Today will be a wet and impactful day with rain and even snow anticipated as a large cold front passes through Maine. Skies will be cloudy with plenty of fog lasting through the morning. Rain will expand across the interstate by the late morning hours, reaching Downeast locations by midday/the early afternoon.
By the early to midafternoon, temperatures will start to drop across northwestern locations as the cold front passes through Maine. This will result in rain turning over to mixed precipitation and eventually snow across the Western Mountains, Moosehead region, and Northern Maine. Rain will continue steadily and at times heavily across the foothills, Interstate, Coast, and Downeast. A few thunderstorms are even possible closer to the coast.
Snow will expand across areas to the northwest of the interstate this evening, reaching all the way down to Interior Midcoast communities, the Bangor region, and Interior Downeast areas by sunset and into the start of the night. Precipitation will taper off across Western Maine shortly after sunset, before exiting the entire state around midnight tonight. High temps today will vary from the low 40s to low 50s with SSE to NW gusts reaching 20-25 mph.
Snowfall totals will vary under 2 inches across Western, Northern, and Interior Downeast locations. However, a few pockets of 2-4 inches are possible, mostly in higher elevations across the mountains. Rainfall totals will accumulate around a half inch to three quarters of an inch when all is said and done.
Precipitation will be out of Maine by midnight tonight, with cloudy conditions giving way to mostly clear skies by sunrise. Lows overnight will dip back below freezing across much of the state, from the low 20s to mid 30s tonight, so cover up any plants or flowers outside. WNW gusts will reach 20-25 mph. A Small Craft Advisory is expected offshore.
Skies will be partly to mostly sunny across the interstate and coast on Monday morning. However, by the late morning to midday hours, clouds will build with a few scattered rain and snow showers in spots. Conditions will remain on the cloudier side in the afternoon before clearing up around sunset into the start of Monday night. Highs will be chilly on Monday, from the low 30s to upper 40s. WNW to SW gusts will be a bit breezy, reaching 20-25 mph, which will add to the wind chill factor.
High pressure will build on Monday night, remaining overhead on Tuesday. Skies will be sunny in the morning, becoming partly to mostly sunny in the afternoon. Highs will remain cool, in the 40s across the board with North to SW gusts only reaching 15-20 mph.
A weaker low-pressure system could bring showers across Maine on Wednesday and Thursday. There is a bit of model uncertainty on exactly when it will impact Maine. The GFS has impacts on Wednesday, while the EURO, GRAF, and GDPS models have most of the impacts on Thursday. We will continue to monitor this system and potential impacts. All it looks to provide as of now are cloudier skies and rain showers, with some snow shower chances farther to the North.
By Friday and Saturday, conditions are trending on the drier side with sunshine and average temperatures returning to the forecast.
SUNDAY: Highs from low 40s to low 50s. Cloudy with AM fog. Rain becoming widespread throughout the day, turning over to snow to the north & west during PM. SSE to NW gusts reach 20-25 mph.
MONDAY: Highs from low 30s to upper 40s. Partly to mostly sunny early. Developing clouds with scattered rain/snow showers by midday/afternoon. WNW to SW gusts reach 20-25 mph.
TUESDAY: Highs throughout the 40s. Sunnier AM. Partly to mostly sunny PM. North to SW gusts reach 15-20 mph.
WEDNESDAY: Highs from low 40s to low 50s. Mostly cloudy with a few rain showers. Few AM snow showers possible North. SSE to SSW gusts reach 20-25 mph.
THURSDAY: Highs from mid 40s to mid 50s. Cloudier skies with rain showers possible. Some AM snow showers possible North. NW gusts reach 20-25 mph.
FRIDAY: Highs from upper 40s to mid 50s. Partly cloudy. NNW gusts reach 20 mph.
