Change Agent - John-Paul Maxfield aims to put nutrients from food waste back into the soil

The United States has a topsoil problem. About 75 percent of it is gone, primarily because the large, single-crop farms that dominate American agriculture rely on chemicals and synthetic fertilizers to produce their harvests, depleting natural soil systems in the process. John-Paul Maxfield thinks compost can help solve this problem. Environmentalists love compost for several reasons, including that it helps divert waste from landfills – the world's largest source of human-produced methane, a greenhouse gas 25 times more potent than carbon dioxide.

Climate Change Mitigation from Pyrolysis

Posted in Biochar, News, Science

Abstract
In the report 2001 by the Intergovernmental Panel on Climate Change (IPCC) projects that climate could warm by as much as 10º F over the next 100 years and we already observed a warming of about 1º F since 1900. Therefore, how to mitigate the greenhouse gas effect is a very important issue since it affects everyone alive and not born.
This paper mainly discusses the impacts of greenhouse gas emission that affects people the most. This paper mainly discusses the following questions:
1) what factors lead to the greenhouse gas effect?
2) How can pyrolysis become a potential source to mitigate the greenhouse gas effect and what are the choices we may have?

Geoengineering: A Potential Biochar Application?

Geoengineering: A Potential Biochar Application?
Could biochar potentially be used to fix nutrients to sustain and increase C Storage in thawing - decompositioning soils?
Higher temperature and decompo- sition rates can also increase nutrient availability, which often has a greater effect on plant growth than temperature (Chapin and Shaver 1996). Decomposition of soil C (in- cluding thawed permafrost C) with concomitant nutrient release could actually increase total ecosystem C storage if low C:N soil organic matter is replaced by higher C:N plant biomass (Shaver et al. 2000). http://www.aibs.org/bioscience-press-releases/resources/Schuur.pdf

Soil amendment

Biochar can be used as a soil amendment to improve yield, improve water quality, reduce soil emissions of greenhouse gases, reduce nutrient leaching, reduce soil acidity, and reduce irrigation and fertilizer requirements http://en.wikipedia.org/wiki/Biochar

Nitrous oxide emission reduction in temperate biochar-amended soil

Posted in Biochar, News, Climate , Science

We found mean N2O emission reductions of 60% compared to soils without addition of biochar

Abstract
Biochar, a pyrolysis product of organic residues, is an amendment for agricultural soils to improve soil fertility, sequester CO2 and reduce greenhouse gas (GHG) emissions.
In highly weathered tropical soils laboratory incubations of soil-biochar mixtures revealed substantial reductions for nitrous oxide (N2O) and carbon dioxide (CO2 5 ).

Using Biochar to Boost Soil Moisture

Posted in Biochar, News, Science

Scientists at the U.S. Department of Agriculture (USDA) are leading the way in learning more about "biochar," the charred biomass created from wood, other plant material, and manure. The studies by Agricultural Research Service (ARS) scientists at laboratories across the country support the USDA priorities of promoting international food security and responding to global climate change. ARS is USDA's chief intramural scientific research agency.

Hope Mine cleanup demonstrates power of biochar

Posted in Biochar, News, Project

A new generation of pioneers have struck proverbial gold at an abandoned silver mine near Aspen. What was once a wasteland of arsenic, cadmium, lead and zinc on a steep mountainside that abuts Castle Creek is now a haven for natural grasses and wildflowers that have stabilized the slope and drastically reduced the risk of the heavy metals crashing into the city’s main water supply.

The striking change of scenery around Hope Mine is the result of the first whole-scale reclamation project ever attempted in the United States, and possibly the world, using biochar — a type of charcoal produced through the thermal treatment of organic material in an oxygen-limited environment. We really were surprised how aggressive the regrowth was,” said John Bennett, executive director of For The Forest, which teamed up with Carbondale-based Flux Farm Foundation at the request of the U.S. Forest Service, which is exploring new ways to partner with private groups to reclaim landscapes. “We did not expect waist-high grass in the very first summer. We thought it would take longer.”

Melbourne to get first biochar plant

Posted in Biochar, News, Project

Stores as much as 50,000 tonnes of carbon dioxide a year

THE country's first commercial biochar plant, to turn green waste into energy and store carbon dioxide, will be built in Melbourne after State Energy Minister Michael O'Brien awarded a $4.5 million grant to Pacific Pyrolysis. PacPyro's ''carbon-negative electricity'' pilot-scale project will turn two tonnes of municipal organic and wood waste an hour into electricity and biochar and store as much as 50,000 tonnes of carbon dioxide a year.
