Winter annual crops such as winter rye (Secale cereale L) can produce biomass feedstock on seasonally fallow land that continues to provide high-value food and feed from summer annuals such as corn and soybeans.
As carbon sequestration and biofuel technologies mature, microalgae-based feedstock will continue to be a critical aspect of the process productivity.
As the production of biofuel continues to grow, more by-products (ranging from upstream, discarded feedstock components to downstream, postproduction residues) are generated, which call for more research and engineering efforts for their effective utilization.
The majority of plastics are obtained from fossil fuels, and as the price of crude oil continues to fluctuate, the price of plastics that are produced from oil feedstocks are expected to oscillate as well (http://articles.ides.com/oil.asp).asp
As biofuel production continues to increase, so will demand for forests to provide sources of biomass feedstocks.
If the use of diesel continues to grow in racing and in everyday driving, Dynamic Fuels has enough feedstock to support four or five more synthetic fuel plants the capacity of Geismar, Mr. Drake said.
It continues to pipelining.
Why? First, as long as Iran continues to operate its uranium enrichment plant at Natanz, it will be no more than 12 months away from producing all the low-enriched uranium feedstock it needs to make its first bomb's worth of highly enriched uranium.
These renewable monomeric feedstocks provide comparable properties to conventional petroleum derived products and are of growing importance as their supply improves and the price of petroleum continues to increase.
This gap in knowledge continues to hamper attempts at engineering inhibitor-tolerant bacterial strains, as evidenced by the persistent low butanol productivity from biomass feedstock and, hence, the high cost of butanol production.
