Polysaccharide biopolymers have been shown to be alternatives established dust suppressants. This study investigates the potential of 14 polysaccharides and proteins from diverse botanical (corn, pea, wheat, cellulose, potato, fava bean) animal (pig, chicken, cow) sources as suppressants on two mine soils (medium-grained sand fine-grained silica sand). Results laboratory tests demonstrate that ...
Miscanthus × giganteus is a giant C4 grass native to Asia. Unlike most C4 species, it is relatively cold tolerant due to adaptations across a wide range of altitudes. These grasses are characterized by high productivity and low input requirements, making them excellent candidates for bioenergy feedstock production. The aim of this study was to investigate the potential for growing Miscanthus on...
The release of colloid-bound trace metals from abandoned coal mine spoils can potentially be a significant source contamination during weathering. We examined the size-dependent enrichment in spoil samples using centrifugation and acid extraction to compare metal loading bulk colloid fractions. A combination X-ray diffraction (XRD), scanning electron microscopy with energy dispersive spectrosco...
Surface mining for coal has contributed to widespread deforestation and soil loss in regions around the world, particularly Appalachia, USA. Mined land reforestation is of interest this other where forests are dominant pre-mining use. This study evaluated mine development on surface-mined sites reforested according Forestry Reclamation Approach, representing a chronosequence time ranging from 0...
