The second-generation (2G) biofuels instead of using first-generation (1G) sugar streams (e.g. sugar cane, sugar palm, sugar beet, vegetables and fruits) and starch-based biomass (e.g. corn, milo, wheat, rice, potatoes, cassava, sweet potatoes and barley) [9, 15, 16] will rely heavily upon lignocellulosic feedstocks.
Results show that it is possible to produce α2 + γ two-phase microstructures consistent with previous studies which have relied upon more expensive and harder to obtain pre-alloyed feedstocks.
Additionally, the composition of the glycerol by-product can change dramatically depending upon the biodiesel feedstock (e.g., vegetable oils or rendered animal fats), the catalyst used, and the degree of post-reaction cleanup (e.g., acidulation and demethylization).
The implementation of bioenergy systems crucially relies upon a sustainable feedstock supply base [22].
For example, the degree of potential reduction in GHG emissions by biofuels is dependent upon the biofuel feedstock, the management practices used and perhaps the nature (scale and distribution) of the industry (Schubert, 2006).
Petrochemicals, Feedstocks.
TR: What feedstocks can you use?
Our analysis indicated preferences were dependent upon individual and environmental characteristics, with younger, more rural landowners significantly more interested in growing feedstocks relative to their older and more urban counterparts.
But as ink and paper are to the desktop printer, feedstock is to the 3D printer, and the composition of those feedstocks is also of environmental concern.
But I would like to see a ban on the use of all purpose-grown feedstocks.
