“…Cost estimates are required for all major process equipment used in the direct conversion of feedstock to biofuel. Cost estimates may be obtained from various sources such as vendor quotes, published detailed TEAs, downloadable biorefinery cost estimate spreadsheets, and databases such as the SCENT tool . Equipment costs can be scaled based on the required biorefinery equipment size using a general scaling equation…”

“…Process departments for an enzymatic hydrolysis biofuel conversion process, for example, typically include pre‐treatment, saccharification and fermentation, distillation, and solids recovery. Waste‐water treatment can be a significant capital cost item . Peters et al include waste‐water treatment as a service facility item and estimate the cost through a range of recommended percentages of TDEC based on typical chemical plants.…”

Constructing a commercial biorefinery involves significant financial and technical risks that may affect investor willingness to commit funds. Repurposing existing industrial facilities has been proposed as a means to lessen the investment risk in constructing a new biorefinery through reduced financial requirements and startup costs. This research provides a decision‐making tool for estimating the repurpose potential of existing industrial facilities considered for conversion to a biorefinery. It applies well‐established techniques for capital cost estimation of Greenfield biorefinery and pulp mill infrastructure and assets to determine their repurpose potential as a biorefinery. It demonstrates how capital cost reduction is highly dependent on the process technology present in the subject facility. A factored approach is employed to assign valuation to the major capital cost components of a Greenfield biorefinery. Existing facilities are then assessed for their compatibility through an infrastructure and asset analysis to determine an estimated capital percent savings that may be realized through repurposing into a biorefinery. Private and public databases and general facility process designs are used to determine the presence of equipment in each facility assessed. A yes/no analysis is performed to assign full cost to facility infrastructure and assets not present in the biorefinery and no cost to those that are present. This methodology provides an economic valuation tool for facility assessments as a metric for facility comparisons, and may be used to assist in decision‐making regarding the suitability of a facility for repurposing. © 2017 Society of Chemical Industry and John Wiley & Sons, Ltd

“…The ash content is related to disposal costs incurred to get rid of ash in excess of the 5% and a dockage of $2.25 per ton per percent ash over 5% was assumed. The carbohydrate specication is required for bioreneries to obtain the required biofuel yields for the NREL design case 41,42 and the dockage was set at a at cost of $6.10 per ton.…”

Sixteen cellulose rich municipal solid waste (MSW) blends were developed and screened using an acidassisted ionic liquid (IL) deconstruction process. Corn stover and switchgrass were chosen to represent herbaceous feedstocks; non-recyclable paper (NRP) and grass clippings (GC) collected from households were chosen as MSW candidates given their abundance in municipal waste streams. The most promising MSW blend: corn stover/non-recyclable paper (CS/NRP) at 80/20 ratio was identified in milliliter-scale screening based on the sugar yield, feedstock cost, and availability. A successful scale-up (600-fold) of the IL-acidolysis process on the identified CS/NRP blend has been achieved. The sugar and lignin streams were recovered and characterized. Mass and material energy flows of the optimized process were presented. Feedstock cost for MSW blends was also discussed. Results suggest the promising potential of using MSW as a feedstock blending agent for biorefineries while maintaining sufficient performance and low feedstock cost. The bench scale (6 L) study is an essential step in demonstrating the scalability of this IL technology.

“…This can produce a low-oxygen product which can serve as a feedstock for the upgrading reactor, increasing hydrocarbon yield and aromatic content of the blendstock ( Figure 4C). Table 1 shows the sustainability metrics for the process shown in Figure 4A [33]. The GHG emissions from the process outlined in Figure 3C is reported to be 15.9 g CO2e/MJ.…”

Conversion of biomass into bioenergy is possible via multiple pathways resulting in the production of biofuels, bioproducts, and biopower. Efficient and sustainable conversion of biomass, however, requires consideration of many environmental and societal parameters in order to minimize negative impacts. Integration of multiple conversion technologies and inclusion of upcoming alternatives, such as bioelectrochemical systems, can minimize these impacts via production of hydrogen, electricity or other forms of energy from the low value streams and improve conservation of resources, such as water and nutrients via recycle and reuse. This report outlines alternate pathways integrating microbial electrolysis in biorefinery schemes to improve energy efficiency, while evaluating environmental sustainability parameters.
