The activated carbon processing facility and biomass power plant formerly owned by Big Island Carbon LLC will be auctioned off online June 17, by order of the U.S. Bankruptcy Court.

According to a statement released by the company staging the auction, items being sold include process, plant support, laboratory/testing, maintenance/shop, and electrical equipment, several pre-engineered metal buildings, and office furniture and equipment.

The plant in Waimea, on Hawaii island, was built to crush and char macadamia nut shells and activate the charcoal-like products in a non-chemical manner for conversion into energy.

Former management says the company identified the steps and costs necessary to prepare the operation for full production, but funding was cut off before full production could begin and the company filed for Chapter 7 bankruptcy liquidation in November of 2013.

A previous, more traditional style auction, was set for April 4. This time around, bidders can preview items on-site, 61-3277 Maluokalani St., in Waimea, from 9 a.m. to 4 p.m. June 14-16, and online at bidspotter.com, where the live webcast auction will begin at 10:30 a.m. Hawaii time on Tuesday, June 17.
