"The significant investment in this technology goes hand in hand with our highest responsibility and top priority at Carnival Corporation, which is compliance, environmental protection and the health, safety and well-being of our guests, the people in the communities we visit and serve, and our shipboard and shoreside personnel," said Bill Burke, chief maritime officer for Carnival Corporation. "We have made great strides in our circular economy focus area and the rollout of nearly 600 biodigesters represents another important milestone for our ongoing efforts to further minimize our impact on the oceans we sail and the communities we visit while supporting overall food waste management efforts and environmental compliance on board our ships."
