Mobilizing mine lands for biobased decarbonization strategies
Abstract Over 163 000 ha of mine lands in Pennsylvania (PA) have the potential to produce willow as a feedstock for renewable energy generation. Each year these lands could produce between 454 000 and 907 000 dry Mg of willow, which can be a feedstock for bioenergy (i.e., biopower) with carbon capture and sequestration (BECCS) or sustainable aviation ...

Strategic techniques for upgrading bio‐oil from fast pyrolysis: a critical review
Abstract Pyrolysis has been the subject of extensive scientific research due to its potential application to various waste streams and byproducts from different production systems. One of its main products is the liquid fraction known as bio‐oil – a complex material composed of a wide variety of organic molecules and a significant water content.

Numerical modeling of gas turbine cooled blades
In contrast to methods that do not take into account multiconnectivity in a broad sense of this term, we develop mathematical models and highly effective combination (BIEM and FDM) numerical methods of calculation of stationary and quasi‐stationary ...

ABSTRACT We utilize a rich dataset of manufacturing firms to investigate the heterogeneous effects of ISO 14001 on the financial performance of certified firms. We employ machine learning techniques, specifically causal tree and causal forest, to uncover these effects. Our findings reveal consistently positive average effects of ISO 14001 certification
