However, locations with high aerial biomass productivity may be preferable for algae cultivation as they are capable of generating a greater amount of microalgal biomass feedstock per unit surface area, thus reducing potential land use impacts.
Production cost (per unit input).
9) Calculate the per unit economics.
Then, the chapter deals with engineering aspects – categorisation of feedstocks, methane production per unit of feedstock, reactor configurations, mass and energy balance of digestion systems, up-scaling laboratory systems to commercial reality and modelling.
As a winter crop, winter rye can provide significant lignocellulosic feedstock for biofuel production per unit land area before planting main summer crop.
Since harvest windows differ across species, gasification fermentation technology would enable the use of specialized harvest and collection machinery throughout many months and reduce the fixed costs of harvest machinery per unit of feedstock.
It is a clean process able to produce high quality synthesis gas with a higher output per unit of feedstock and that allows for the chemical storage of solar energy in the form of a readily transportable fuel, among other advantages.
On the other hand, the batch profit is a measure of the profit generated per unit of feedstock.
Further, our methodology allows us to predict the environmental impacts per capita for the various sources (i.e., per unit of ethylene feedstock source and per unit of energy source).
While reducing conversion costs and increasing ethanol yield per unit mass of feedstock will initially be achieved through optimizing processing tools and techniques, further cost reductions and yield increases could be attained through improving biofeedstock quality [ 3].
The per-unit assessments ranged from $33,250 to $339,125.
