Graphyte, a new company incubated by Bill Gates’s investment group Breakthrough Energy Ventures, announced Monday that it has created a method for turning bits of wood chips and rice hulls into low-cost, dehydrated chunks of plant matter. Those blocks of carbon-laden plant matter — which look a bit like shoe-box sized Lego blocks — can then be buried deep underground for hundreds of years.
Typically i believe that it tends to be about twenty to forty percent of the tree by mass, but that’s still nearly doubling the about of carbon we sequester if we can sequester it.
