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.

  • If you’ve ever been around a logging operation, you’d see how much (half?) of the plant matter extracted doesn’t make it into a logging truck, but is instead piled unto 3-story high heaps and then burned. Being able to sequester that material instead would be amazing

    • 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.

        • Even when it is bury for no value vs sell to replace carbon-producing materials? I don’t buy it. Very few places are so remote that there is zero local-ish demand for building materials and they have to build facilities and support workers in those remote places instead.
