University of Pennsylvania researchers lead project studying phytoliths in biofuel feedstocks

October 16, 2019 |

In Pennsylvania, an international, multidisciplinary team led by University of Pennsylvania mineralogists used highly sensitive microscopy to study phytoliths, small deposits of minerals containing silicon or calcium present in certain plants. These chemical elements are absorbed from the soil along with other nutrients. The phytoliths lend plants strength and structure and are common in some plant families commonly used for biofuel, such as grasses.

Reporting in Industrial Crops and Products, the researchers found that phytoliths remain after plants are burned in a biofuel combustion facility but in particle sizes large enough that they likely don’t pose a health risk. But because phytoliths can reduce the efficiency of energy conversion, power plants must factor them into their operations, the team notes. On the other hand, the phytolith-containing ash resulting from combustion could be sold for use in cement production or as fertilizer.
