The results show that the proposed system can be more energy efficient and provide a more sustainable option when compared to conventional extractive distillation or thermally coupled sequences.
It was observed that the fraction of other extractives (non-quantified components) was higher in both AC1RS and AC2RS extractions when compared to UTRS extraction.
We've helped change the game when it comes to accessing publicly available land contracts, but we're still far behind when compared to transparency efforts in the extractive industries.
In addition, there were many new components (mainly yellow pigments) in the extracellular broth after extractive cultivation compared to both the conventional intracellular and extracellular pigment compositions (Fig. 5a, b).
Here, the spectra from several unextracted and Soxhlet-extracted lignocellulosic materials (red spruce sapwood, trembling aspen sapwood, and Arabidopsis thaliana) were compared to evaluate the influence of extractive compounds on ToF-SIMS spectra below 200 Da, and possible mass overlap of peaks from these compounds with peaks originating from polysaccharides or lignin.
VS (positive control) gave significant mortality, and the LC50 values of the different extractives were compared to this positive control.
Previous studies show that corn stover with severe AFEX pretreatment results in a 50% increase in the total water extractives when compared to corn stover undergoing more moderate AFEX pretreatment.
Comparison of the yields of Glc from CS in the presence of inhibitors, compared to CS alone or CS + extractives from corn, indicated that forbs extractives caused some inhibition (indicated by the relative heights of the black bars in Figure 4).
Besides, he notes, mining ice cubes from glaciers on the scale that Svaice is proposing would be tiny compared to the environmental impact of most extractive and energy-intensive industries, such as aluminum production.
When compared to the environmental impacts of other extractive industries – namely oil and gas – ice mining is, at least on paper, small potatoes, says Sigurd Enge, who advises Oslo-based environmental group the Bellona Foundation on Arctic issues.
