It is headquarters are in Scottsdale, Arizona, USA. == Carbon negative process == PetroSun uses a process called "carbon negative energy production". Organic matter is burnt in a kiln with limited oxygen (pyrolysis). This produces carbon dioxide, hydrogen and charcoal (which PetroSun calls "biochar"). The carbon dioxide is used as a feedstock to grow algae for biofuel while the hydrogen is burnt to generate electricity. The biochar, which contains a lot of carbon, is used as a fertiliser. If the feedstock is plant matter which fixed atmospheric carbon dioxide, and part of its carbon becomes fertiliser which will not be burnt to re-release the carbon into the atmosphere, the net result is a reduction in atmospheric carbon, ''i.e.''. an overall carbon-negative process. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「PetroSun」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
