Scale-up of yeast extract usage will be expensive, whereas corn steep liquor may be a suitable and more cost-effective replacement [ 39], especially since it is conceptually possible to produce this in a biorefinery or at least in conjunction with corn-based feedstock processing.
The development of computationally efficient, accurate, and stable dynamic reduced order models of Shell Entrained-flow gasifiers would help to better understand the influence of design variables, feedstocks, and processing conditions on the operating performance of the reactors.
Sustaining the development of advanced poplar feedstocks and processing technology for economically viable biofuel production within the EU will provide climate mitigation benefits within the technological, economic and environmental constraints that apply.
C/N ratio of compost ranged from 20 to 27 after 1 day of feedstock processing inside the composter (Fig. 3).
It provides an introduction to biomass feedstock processing along with the development of plant materials synthesis and formation, especially with protein, starch polymers, and oils.
In fact, part of the energy is required for the feedstock processing before energy conversion, while the possible energy surplus could be exploited by the Fongo Tongo community for their energy needs.
Finally, an economic analysis shows that 2000 metric tonnes (Mt) per day of corn stover feedstock processing results in a minimum selling price of $633 per Mt if using the best possible parameters.
It was found that the economic viability of biochar-based bioenergy production system within the life cycle analysis system boundary based on study assumptions is directly dependent on costs of pyrolysis, feedstock processing (drying, grinding and pelletization) and collection on site and the value of total carbon offset provided by the system.
Polymers derived from nonpetrochemical sources are becoming more viable and economical as improvements in feedstock, processing, and technology are developed.
