This fall, CalPlant I will introduce the long-awaited CalAg MDF, the composite panel of the 21st Century.

When construction is completed in fall 2019, CalPlant I will be the world’s first commercial-scale producer of rice straw-based medium density fiberboard (MDF), annually supplying approximately 140 million square feet of no-added-formaldehyde MDF to the building products industry.

CalPlant I and its predecessor company CalAg LLC have spent many years researching, developing and patenting a process to make high quality MDF using annually renewable rice straw as the feedstock, the disposal of which has posed environmental issues in California for over a century. Rice straw is an agricultural waste product of the annual harvest, and all furnish for the plant will be procured from Sacramento Valley rice growers within a 15- to 25-mile radius of the plant site in Willows, California.

Currently, the most common practice of straw disposal is to initiate a decomposition process by flooding the fields after harvest. This practice uses a large volume of incremental amounts of precious water. By processing rice straw into MDF, CalPlant I will significantly reduce the levels of water that would have been diverted from regional waterways to flood rice fields after harvest.
