Turning Forestry Waste into Renewable DieselHow could Strategic Biofuels achieve a NEGATIVE -294 Carbon Intensity score in a road fuel?Let's Chat

| Here's CEO Paul Schubert explaining their project in Louisiana:

The carbon intensity (CI) of fuels is California's primary metric for judging the environmental damage or benefit of a transportation fuel. Its units are "grams of carbon dioxide equivalent per megajoule," or gCO2e/MJ. The smaller (more negative) a CI score, the more potential for earning valuable LCFS credits when sold in California.
How good would that CI score be? As calculated by California's Air Resources Board, traditional ultra-low-sulfur diesel has a CI of about 100. Using an otherwise waste product like used cooking oil (UCO) is considered a highly beneficial feedstock for making renewable diesel and has a CI of about 20.
Using fresh soybean oil? About CI 55, higher because farming and land use are involved.
Beef tallow is also well regarded at around CI 33.
How Are Forestry Trimmings Collected?Forestry trimmings are not something everyone sees in their daily life. But, far from cities, in rural industry, these waste products are ready to be collected for carbon-abatement purposes. Paul explains: |
So-called "injection wells," which are deep wells often used to dispose of used or "produced" water in oil- and gas-field operations, are also how carbon is sequestered in the Strategic Biofuels project. And it has been shown that these injection wells can sometimes contribute to the likelihood of earthquakes. However, seismic activity has never been a concern in this corner of Louisiana. |
It isn't just injection wells that this new-energy project has in common with oil and gas development. The local and state governments are recognizing how oilfield workers and technology are being redeployed to benefit the community and environment. |
Surprising Unanimous VoteMuch like in gas development, pore rights – who owns the economic benefit of the rock formations and how they're used – are crucial in this development. When the owner of the pore rights is unknown, developers are stalled. But Louisiana passed a law allowing eminent domain process to secure those rights. Did the vote barely pass in Louisiana, a major oil-and-gas state? Paul explains his surprise at the unanimous vote. |
A site diagram shows how the fuel plant, power plant, and river port would be arranged. A $15 million grant is being used to enhance the highway and rail facilities to serve the plant. The groundbreaking happened in December. |

The U.S. Forest Service has an interest in controlling this forestry waste. But, as part of the federal government, they also want to ensure the fuel being produced complies with renewable-fuel standards and doesn't expand forest-harvesting land use. Strategic Biofuels partnered with the Forest Service to establish standards to create these policies. Weaver and Tidwell and U.S. EPA were also at the table. What benefits to the community might this project bring? This project is extremely rural, in north-central Louisiana, about 25 miles south of the city of Monroe and on the Ouachita river. The average household income is around $35,000 per year. |
