Biochar price forecasting: A novel methodology for enhancing market stability and economic viability.

The co-production of char and liquid fuel, marketed as carbon-sequestering biochar, presents an economic opportunity, particularly when biofuel prices are low. However, the biochar market remains underdeveloped, with significant price volatility complicating techno-economic assessments (TEA). This variability arises from heterogeneous biochar properties and its diverse applications across agriculture, forestry, and environmental remediation.

Hydrothermal carbonization coupled with fast pyrolysis of almond shells: Valorization and production of valuable chemicals.

In this study, it was found that hydrothermal carbonization (HTC) can be an effective method for almond shell (AS) valorization. The severity of HTC treatment had a significant effect on hydrochar yields, with higher severity promoting carbonization but reducing yields. Furthermore, the work found that HTC treatment effectively demineralized biomass samples by removing inorganic material that could catalyze carbonization.

Fast pyrolysis as an alternative to the valorization of olive mill wastes.

Background: The valorization of organic wastes through fast pyrolysis appears to be a highly promising option for decreasing pollutants and reducing consumption of natural resources. For this purpose, three different olive pomace samples were studied to determine how olive crop location and the extraction process could influence bio-oil product distribution. Olive pomace was selected as the feedstock due to the importance of the olive oil industry in Spain.
