Pulp mill devastates swans' sanctuary in Chile
A recently opened pulp mill
in Chile has devastated one of South America's most biologically outstanding wetlands, decimating its famed population of black-necked swans, along with most other bird life, a WWF-led team of investigators said Monday.
"What was probably the largest population of bla...

Energy crops take a roasting
Torrefaction is increasingly seen as a desirable treatment for biomass because it creates a solid product which is easier to store, transport and mill
than raw biomass.
The study examined the energy crops willow, canary grass and agricultural residue wheat straw to see what happened when they went...

A potential approach is to combine the black liquor with a coal slurry and process that. Paper mill
