Alexander & Baldwin trialing corn and sorghum as biogas feedstock

In Hawaii, as part of Alexander & Baldwin’s diversification into biofuels from its sugarcane past, the company began growing corn and sorghum a few months ago for feedstock that will produce biogas and in turn power the Kahului wastewater treatment facility. If the trial proves successful, the crops could be grown on as much as 500 acres. The crops will be rotated with legumes for nitrogen fixing and cover crops as well. Pongamia isn’t envisioned as a feedstock for the biogas facility despite starting a 250 acre trial that could expand to 2,000 acres over time because the company hasn’t yet decided on how the seeds will be processed.
