when the temperature gets above 350 degrees, the high-molecular-weight hydrocarbons, the resins and asphaltenes, undergo a series of cracking and condensation reactions to form solid char, similar to the petroleum coke produced in refineries.
Rice University pyrolysed oil-contaminated soil to reduce total petroleum hydrocarbons below US federal standards, while leaving beneficial carbons. While this technology may not be used to grow food, they demonstrated success growing lettuce, which is recognized to be sensitive to hydrocarbon contamination.
Paper mill byproducts made into biochar serve in 'totes' as filtration media for heavy metals in roof and storm water runoff. Efficiency is greater than expected: 99% of zinc and 95% of copper removed.
Bob Cirino is "Biochar Bob". In a visit to the Via Organica Ranch near San Miguel, Mexico, he interviews Rachel Kastner and local farmers who are learning and applying ideas of regenerative agriculture, growing lots of healthy food in small spaces, and incorporating biochar in innovative ways like under turkey bedding where it controls ammonia and produces a rich composted product.
By making biochar from brush and other hard to compost organic material, you can improve soil — it enhances nutrient availability and also enables soil to retain nutrients longer.
Dolph Cooke demonstrates biochar making for farm scale with the Moxham open barrel kiln. The "pyrolysis front" of flame consumes any unburned gases coming from the charring biomass at the bottom.
Craig Sams' company Green & Black's makes chocolate from cacao grown in organic agroforestry in Belize, and biochar made from farm-scale retorts enhances the soil sustainably.
Solar-Powered Toilet Unveiled - the product of a grant from the Gates Foundation, this equipment produces safe natural fertilizer from human waste, using biochar and solar heat. This addresses critical sanitation problems in many parts of the world which lack conventional sewage systems, and recycles the valuable nutrients that sewers waste.

From Forbes Magazine, mainstream business attention: "Cool Planet: A Company That Makes Biochar And Gasoline"
Frank Strie says Tasmania needs to develop a carbon economy with biochar at the centre of the state's 'clean energy' mix. "Yes, it is a revolution but a friendly one. It's far more than just looking at biochar as a single entity. It's part of a much bigger process, and it fits into organic farming, with a clean, green and clever image and land restoration."
From Carbon Gold: "Biochar has in turn been proven to improve the health and survival rates of living trees, keeping more of our CO2 absorbing trees alive and strong." This article describes demonstration projects with soil enhancements including biochar.
Cool Planet’s biochar production process features an extra step that tailors the biochar to best fit a particular application. As a result, field trials have shown Cool Terra can increase crop yields while reducing water and fertilizer inputs by as much as 50 percent.
New England Biochar's new video on YouTube shows off their new integrated production facility including efficient use of process heat. Surprise ending!
The future of sustainable livestock production is here, say Cambridge researchers. Not a biochar article, but biochar could contribute to these techniques.
Biochar quiets microbes, including some plant pathogens. In this experiment, E.Coli cultures are tested for microbes' ability to signal each other in the presence of biochar with various characteristics. The goal is to provide a simple guide to tailor production temperatures for intended uses.
"Working on solutions to some of the world’s threatening environmental challenges and creating the world we want to live in is a thrilling opportunity. At Remineralize the Earth we are doing just that – working on research that has the potential to alleviate many of the environmental and agricultural problems humanity faces today, such as climate change, air pollution, unsustainable agriculture, and poor water quality."
Kelpie Wilson writes about Baron Justus Liebig, who researched the applications of charcoal long before the age of industrial agriculture: "In the 19th century, the issues that biochar could help solve were related to health, disease, poverty, and above all, the recycling of human sewage to replenish the soil."
