Ravensdown has unveiled new methane mitigating technology that it claims virtually eliminates the methane emitted from effluent ponds.
"As farmers and growers grapple with environmental and climate change regulations they are crying out for leadership and user-friendly technologies to make adjustments inside the farm gate," he says.
"We have been using Ravensdown technologies like Hawke Eye and N Protect to better manage our whole operation but more needs to be donw in this space."
Since retiring from politics, Guy - the former Minister for Primary Industries for five years - says he's overseen massive on-farm development. This includes building a new twin rotary farm dairy, as well as a new effluent and water system.
He adds that he's also become active in governance, transferring the "critical thinking, connections and experiences gained from 15 years in Parliament and around the Cabinet table to the board room".
Guy currently serves on the boards of Barenbrug (formerly Agriseeds) and the Horowhenua Kapiti Rugby Football Union.
