"Today, CarbonScape takes leftovers from timber making, but Williams believes it could also make use of so-called slash, which is the waste branches and other unwanted wood left in forests during logging. The wood chips are heated using a process known as pyrolysis to create biochar, a carbon-rich material that is then milled and converted to a raw form of graphite. That is purified and coated to get the quality needed for battery anodes.

目前，CarbonScap使用木材加工過程中的邊角料，但威廉姆斯認為，還可以利用所謂的「採伐剩餘物」，也就是伐木時留在森林中的廢棄枝椏和其他沒用的木頭。碎木片通過一種被稱為「熱分解」的工藝加熱，生成生物炭，隨後，這種富碳材料經過研磨，轉化為粗加工石墨。經過提純和塗層處理，便可達到製造電池陽極所需的品質要求。"
