Who Are We?

CASTLE ROCK INDUSTRIES, LLC, a wholly owned subsidiary of Energy Holdings, LLC, was established in 2010 with operations beginning in the latter part of 2012 in Selma, Dallas County, Alabama. The facility is designed to extract and purify bio-diesel feedstock derived solely from materials traditionally underutilized and wasted in the typical process, such as used cooking oil, yellow grease, and distillers corn oil. These inputs are processed and refined into biodiesel feedstock oil, animal feed, and high-value co-products.

Our Facility

The property is situated on 5.5 acres of a 20 acre parcel of property in Selma, Dallas County, Alabama. Physical Improvements consist of the 2,880 square foot (SF) Motor Control building, 2,700 SF Utility building, the 360 SF Lab building, Production Process Skid including 82’ and 39’ towers, and a Tank Farm with 750,000 gallon capacity. Elements of construction include foundations of concrete slabs on perimeter beams and steel beam skeleton with light weight standing seam metal panel walls and roofs on the Motor Control, Lab and the Utility buildings. All structures except the Lab are protected by concrete spill containment troughs along their perimeter.

There are (2) concrete catch basins to channel any truck spills for recycle production and underground piping systems that carry waste-water to either a reservoir retention pond or the Dallas County sewer system. Carbon steel tanks are positioned in concrete containment stations. Surrounding the plant production area is a concrete perimeter road that has been angled inboard to protect against truck spills. Along the perimeter cyclone fencing are sumps with riprap stone beds which serve to channel water build-up, if any, away from the plant.
