The activated carbon processing facility and biomass power plant formerly owned by Big Island Carbon LLC and its affiliates in Kawaihae, is to be auctioned off by order of the U.S. Bankruptcy Court in Delaware.

The plant was built to crush, size and char locally grown macadamia nut shells and then activate the charred shells in a non-chemical manner. The biomass power plant was equipped to support the facility with energy derived from pyrolysis oil created by the process, according to Jeff Tanenbaum, president of Tiger Remarketing Services, which is assisting in the liquidation auction.

The Hawaii island facilities, 35 miles north of Kailua-Kona, are being marketed in a sealed-bid offering that closes at 2 p.m. Hawaii time Friday, April 4.

Bankruptcy trustee Charles A. Stanziale of McCarter & English LLP is directing the auction.
