The Organic Refuse Conversion Alternative (ORCA) machine, a food waste disposal system, is now in use at the Phoenix Convention Center (PCC). The addition of the ORCA machine, which biologically converts organic food waste into a nutrient rich liquid through an accelerated decomposition process, represents a leap in sustainability for the convention center, keeping the facility on the cutting-edge of sustainable operations.
Contained within a stainless steel box the size of a refrigerator, the ORCA has the capability of decomposing 2,000 pounds of food waste into a liquid effluent each day.
The process employs principles that are similar to outdoor composting. The ORCA creates a biodegradable environment by churning food waste, fresh water and bio-chips that activate thousands of micro-organisms; through a process that converts food waste into safe wastewater. Phoenix is the first major convention center in the United States to use this food waste disposal system.
As populations increase, municipalities like Phoenix are looking for alternative solutions to preserving landfill capacities by managing waste through greater innovation. The ORCA provides a sustainable solution for high density urban areas compared to the traditional landfill environments where most food waste is hauled to for composting.
