Coal can feed products well beyond combustion. The study sets out routes to rare earth elements held in particular seams, building materials made with carbon fibre and carbon char, coal foam and graphene composites, carbon black and activated carbon, including a coal derived activated carbon reported to hold four times the gas of compressed natural gas at lower pressure.
The impact of cattle grazing on rehabilitated land
Two annual surveys of species composition, biomass and soil sampling inside and outside fenced plots on rehabilitated pasture at an opencast colliery near Ogies, with benchmark sites for comparison.
What this report foundGrazing pressure on the rehabilitated block ran at roughly three times the estimated carrying capacity.
R1500,00
Grazing pressure on the rehabilitated block ran at roughly three times the estimated carrying capacity. The sward was dominated by low quality grasses with a high proportion of bare ground and a raised erosion risk. Fenced exclosures over one year changed the abundance of a few species, but the vegetation showed no clear direction of recovery.
