LIVING GREEN ON MACADAMIA ROAD
MAUNA LOA MACADAMIA NUT MANUFACTURING PLANT
CONVERTS SHELL WASTE INTO ENERGY
Mauna Loa Macadamia Nut Corporation continues to reduce its carbon footprint by burning macadamia husks, shells, and waste kernel to generate the energy required to power its Hilo processing facility. This renewable bio fuel accounts for 60% of the facility's electricity usage; greatly reducing Mauna Loa's reliance on oil produced energy.
The Mauna Loa Macadamia Nut plant processes approximately 180,000 pounds of nut in shell and packages roughly 48,000 pounds of kernel daily. The shell produces approximately 9000 BTUs per pound of energy when burned. The heat generated produces steam and the energy in the steam is converted into electricity through a steam turbine/generator.
Mauna Loa has also reduced its overall reliance on electrical energy by channeling the generated steam to heat the factory's nut drying tanks. Also, to further reduce reliance on non-organic fertilizer, waste macadamia husks are composted and returned as organic fertilizer to the orchards
"We live in such special and delicate surroundings that we sometimes take it for granted. It is surreal to see volcanoes and lush forests everyday and we easily forget how privileged we are or the responsibility we all have in preserving and protecting our environment," stated Charles Young, Plant Manager at Mauna Loa Macadamia Nut Corporation.
