ReChar started a Kickstarter project funding:
Black Revolution is a soilless growth media for plants containing biochar, coconut husk and compost. Biochar is a charcoal soil amendment made from waste that improves nutrient retention, offsets CO2 and has the potential to help feed our growing planet. Black Revolution is the world's first carbon-negative replacement for soil made entirely from waste. It's lighter than traditional soil, so it works great in rooftop or urban environments. The potting soil and chemical fertilizer industries are traditionally some of the most environmentally destructive in the world.

Chemical fertilizers require massive amounts of fossil fuels and pollute our rivers and streams. Potting soils contain peat moss and vermiculite: non-renewable resources mined from endangered areas around the world.

The U.S. State Department announced:
The United States continues to be deeply concerned by the humanitarian emergency in the Horn of Africa, and particularly the hard-hit Somali population. Despite the end of famine conditions in February, nearly 10 million people in the region still require humanitarian assistance. For this reason, the United States Government is providing an additional nearly $50 million in aid for refugees and drought-affected communities in Somalia, Ethiopia, and Kenya in addition to what we have already provided.

Pacific Pyrolysis (PacPyro) has been offered $4.5 million by the Victorian Government to pilot a commercial-scale production facility in Melbourne. The project will demonstrate PacPyro’s proprietary technology’s ability to deliver a solution for urban green and wood waste by converting it into renewable electricity and biochar.

Eliza Barclay from NPR writes:
You've probably heard of compost – that thick chocolate-colored stuff that's an organic gardener's best friend and supplies plants with all kinds of succulent nutrients.

But what about biochar? It's another ancient farming material made from slow-burned wood (also known as charcoal) that holds nutrients and water into soil without them draining away. And lately it has enjoyed a certain revival because it can also pull and store the carbon in greenhouse gases from the air. Everyone from California grape growers to home gardeners on YouTube is trying it out.

From PR Web: Worm condos. Terra Preta. Black Gold. Whatever it’s called, healthy soil is the most important tool in successful gardening. With the new Soil Reef™ blend being launched this spring, gardeners can create a healthy, organic and permanent home for beneficial organisms living in the soil.

The new blend combines OMRI-listed compost and worm castings from Organic Mechanics® with biochar, adding a unique porous carbon to the soil to create a habitat for life to thrive. How does it work? Soil Reef creates a network of nearly permanent, natural carbon structures throughout your soil, which hold onto water and nutrients, and create homes for microorganisms.

The use of Biochar to act as a carbon sink is causing quite a stir among environmentalists and scientists alike. This ancient technology of burning organic matter then burying it in the ground to fertilize crops may have been around for over 3000 years in the Amazon Basin, but the research that shows that this method of fertilization will also absorb some of the carbon in the atmosphere means that this could be a really viable solution to the long term problem of carbon over production.

Abstract
Bioavailability and bioaccessibility determine the level of metal toxicity in the soils. Inorganic soil amendments may decrease metal bioavailability and enhance soil quality. This study used mussel shell, cow bone, and biochar to reduce lead (Pb) toxicity in the highly contaminated military shooting range soil in Korea. Water-soluble and 1-M ammonium nitrate extractions, and a modified physiologically based extraction test (PBET) were performed to determine Pb bioavailability and bioaccessibility in the soil, respectively. Active C in the soil was also measured to evaluate the effects of the amendments on biological soil quality.

The Pb contaminated soil was diluted in serial with uncontaminated soil for the bioassays. Seed germination and root elongation tests using lettuce (Lactuca sativa) showed increases in germination percentage and root length in soil treated with the amendments. Biochar was most effective and increased seed germination by 360% and root length by 189% compared to the unamended soil.

Up to 20% soil dilution resulted in more than 50% seed germination. Bioavailability and bioaccessibility of Pb in the soils were decreased by 92.5% and 48.5% with mussel shell, by 84.8% and 34.5% with cow bone, and by 75.8% and 12.5% with biochar, respectively, compared to the unamended soil. We found that the Pb availability in the military shooting range soil can be reduced effectively by the tested amendments or soil dilution alternately, thereby decreasing the risk of ecotoxicity. Furthermore, the increasing active C from the amendments revitalized the soil contaminated with Pb.

New South Wales, Australia based waste to energy technology developer, Pacific Pyrolysis (PacPyro), is seeking to raise between $2.2 million and $4 million from an initial public offering and then list on the Australian Securities Exchange, according to a report in The Australia.

According to the report the company eventually hopes to utilise used nappies to generate energy, but is currently focused on processing organic waste with it pyrolysis based waste treatment technology. PacPyro is developing and commercialising its slow pyrolysis technology under which organic material such as green waste or chicken manure is heated at high temperatures until it decomposes and creates a gas and a "biochar", the report said.
