http://www.youtube.com/watch?v=N-CeR6jL25w Greg will relate the good, the bad, the ugly and the very, very ugly experiences of making biochar and power at California’s largest two “small scale” gasification plants. HE will talk about future developments as well as the changing economic interrelation between biochar, power and heat. http://www.youtube.com/watch?v=2UYLmLlDGBM Olivier Lepez will share the story of Biogreen's continuous pyrolysis process that produces biochar from various feedstocks - examples of heat and mass balance, syngas composition and valorization, characterisation of a typical biochar produced (physical, chemical, toxicology) and its performance on water retention.
