CalPlant MDF Operation Expects to Begin Production in 2020

CalPlant I LLC (CalPlant), the $315 million rice straw-based MDF plant under construction in Willows, Calif., will begin production in the first quarter of 2020, according to CalPlant CEO Jerry Uhland.

The MDF plant currently under construction is expected to start operating in the first quarter of 2020.

Construction of the manufacturing facility is nearly complete, and an inventory of almost 350,000 tons of rice straw is currently in storage at the CalPlant site for the first run of panels, which should roll off the line this coming January.

“This facility is the first of its kind in the world in so many ways,” Uhland says. “Not only will it have a production capacity to supply 30 percent of California’s MDF demand, it will significantly reduce the use of water to flood rice fields in the Sacramento Valley, thereby cutting the production of greenhouse gases. Those aspects, along with the tremendous direct and indirect benefits the plant operations will bring to the Willows area, make this a legacy project for Glenn County and the state of California.”

CalPlant will be a commercial-scale producer of no-added-formaldehyde, rice straw-based MDF, and at design capacity, the plant will produce more than 140 million square feet (¾-inch basis) annually. Rice straw is an annually renewable raw material, with all of the material for the plant being procured each year from Sacramento Valley rice growers within a 15- to 25-mile radius of the plant site.

Employing a Generation 9 Siempelkamp ContiRoll continuous press, which is 10 feet wide and 115 feet (35 meters) long, CalPlant will be staffed by 115 full-time employees with 450 part-time jobs created during the annual straw-collection period. The mill will be able to produce MDF thicknesses of 2 millimeters to 30 millimeters.

Columbia Forest Products, who is the exclusive sales agent for CalPlant, is an investor in the project and has been a partner during development of the project.

In addition to its formaldehyde-free adhesive system, which will guarantee compliance with Federal TSCA Title VI regulations on formaldehyde emissions from composite panels, CalPlant’s operations will produce less volatile organic compound (VOC) emissions due to its feedstock and is expected to be a minor source of emissions under EPA rules. Its reclamation of approximately 20 percent of the Sacramento Valley’s rice straw waste will also result in savings of the water now used to flood fields to decompose straw after the annual harvest.
