A Cheap, Low-Tech Solution For Storing Carbon? Researchers Suggest Burying Wood
Researchers propose a "deceptively simple" way to sequester carbon, reports the Washington Post: burying wood underground: Forests are Earth's lungs, sucking up six times more carbon dioxide (CO2) than the amount people pump into the atmosphere every year by burning coal and other fossil fuels. ...
While other carbon-capture technologies rely on expensive and energy-intensive machines to extract CO2, the tools for putting wood underground are simple: a tractor and a backhoe. To test the idea, [Ning Zeng, a University of Maryland climate scientist] worked with colleagues in Quebec to entomb wood under clay soil on a crop field about 30 miles east of Montreal... Comparing the old chunk of wood to a freshly cut piece of cedar showed the ancient log lost less than 5 percent of its carbon over the millennia.
