by Lee Imada (Maui News) A&B subsidiary to supply biofuel for power project at wastewater plant — Alexander & Baldwin Inc. has begun growing sorghum and corn on Maui as part of a test project to develop biofuel to feed a planned anaerobic digester that would produce methane gas to power the Kahului wastewater treatment facility, an A&B spokesman said last week.

HC&S, a former subsidiary of A&B, shut down operations in December, which opened up 36,000 acres of former sugar cane fields. A&B has said that it is developing various diversified agricultural ventures on the old sugar cane land, and announced in May that it had set up wholly owned subsidiary Kulolio Ranch on 4,000 acres in Hamakuapoko to raise cattle for Maui Cattle Co. partners.

Last month, A&B announced a partnership with Oakland, Calif.-based TerViva to produce biofuel from pongamia trees on 250 acres in north Kihei/Maalaea. A&B CEO Chris Benjamin said in May that the partnership to produce seed oil could expand to 2,000 acres.

Pongamia, however, will not be powering the anaerobic digester at the Wailuku-Kahului Wastewater Reclamation Facility near Kanaha, Pai said. The pongamia project is “still in the early stages,” and A&B has not decided on processing facilities for the seed oil, he said.

But A&B is “focusing on crops that grow in rows and can be mechanically harvested, such as sorghum and corn” for Anaergia Services Maui All Natural Alternative’s power project at the wastewater treatment plant, Pai said.

“We will rotate these plantings with cover crops and legumes to fix nitrogen and other nutrients in the soil,” he added. READ MORE
