Populus leaf

A lot goes into the process of turning plant materials into fuel. Here’s a look at Oak Ridge National Laboratory’s work in biofuels.

This is a close-up of a Populus deltoides leaf. Chloroplasts in the leaves have chlorophyll which captures and converts CO2 during the photosynthesis process.

Samples

These processed Populus deltoides samples help researchers determine which genetic lines are best for fuel production. In the background are live Populus seedlings.
