Professor Jerry D. Murphy is one of the most renowned experts in the field of renewable fuels and circular economy.  No one better than him could, therefore, remind us of the countless advantages that biogas, biomethane/RNG and biohydrogen can bring to our planet and to our communities. In this Web Talk, we spoke with Professor Murphy about biogas as a means to make the most of the various kinds of available waste, as a biological fertilizer, as a programmable and accumulable energy source and as an integral part of what will hopefully be a much greener future.
