“…The expansion of cereal-based bioethanol production raised initial concerns that the concurrent increased supply of the traditional co-product (DDGS) would exceed feed use potential [34]. However, the reframing of bioethanol production into biorefining, where multiple product streams are empirically scrutinized and modelled for optimum plant design [35], has revolutionized the sustainability of cereal-based bioethanol plants. The new engineering and plant design focus has been on optimizing the generation of high-quality protein from the bioethanol plants [36].…”

The recent conceptual pivot from bioethanol production to ethanol biorefining has led to development of protein derived by fractionating the non-ethanol streams post fermentation within the plant. The aim of this study was to identify the effect of replacing dietary soy with corn-fermented protein (CFP) on performance of fast-growing meat species and the impact on the carbon footprint associated with the feed for each species. The study contains trials on 3 species, broiler, turkey and salmon. In trial one, 324 broiler chicks were allocated randomly to 36 pens distributed into 3 dietary treatments; control (0% CFP), 5% CFP and 10% CFP; for 35 days. In trial 2, 150 turkey poults were allocated to 3 treatments: control (0 CFP), 4% CFP and 8% CFP for 35 days. In trial 3, 525 Atlantic Salmon (starting weight 304 g ± 10.7 g) were raised in 15 saltwater tanks for 84 days with 5 treatments, control (0% CFP), 5% CFP, 10% CFP, 15% CFP and 20% CFP. Growth response, nutrient utilisation and carbon footprint were assessed in each trial. Replacement of soy with CFP showed limited differences in growth response and nutrient utilization but replacing soy bean meal with CFP at rate of 5%, 8% and 10% in broiler, turkey and salmon diets, respectively resulted in a 14% decrease in carbon footprint of diet manufacturing. This investigation shows coupling bioethanol production with poultry and salmon production represents a highly effective circular economy contributing to multiple UN Sustainable Development Goals.

“…South Korea has 16 administrative divisions (AD); each AD can provide a harvesting site, collection facility, drying unit, biorefinery, and demand zone (see Table ). The data on the distance between them were obtained from a previous study Considering the land requirements of the refineries, dryers, and storage facilities calculated from a previous report, only four facilities from each technology can be built in each AD. Each third-generation biorefinery (i.e., valorizing Saccharina japonica) was assumed to use biochemical conversion (fermentation).…”

“…Similarly, each lignocellulosic biorefinery employed thermochemical conversion (gasification) and was assumed to operate within one of the following six capacities: 0–10, 10–20, 20–50, 50–90, 90–133, and 133–164 MGY. The design and cost estimates were based on the superstructure developed as reported previously . Bed drying was used to reduce the moisture content of raw seaweed from 85 to 15%, as performed in previous studies and has a capacity of 7.5 million dry tons per year (DTPY).…”

As the global climate crisis worsens and fossil fuels deplete, renewable energy sources have become more appealing. Biofuel is one of the promising sources produced from multiple biomass sources, as long as it does not compromise food security. In this direction, a multiperiod mixed-integer linear programming model incorporating three types of biomass simultaneously is developed to provide a second- and third-generation biofuel supply chain. The proposed model minimizes the total annualized cost by selecting raw materials, locating production facilities, placing storage facilities, and identifying optimal material flows by defining a deference path for each feedstock. A case study addressing bioethanol production in South Korea was then conducted to evaluate the performance of the developed model; the results demonstrated a clear reduction in the total annualized cost by incorporating multiple feedstocks. Using multiple feedstocks allowed for the total ethanol demand of South Korea to be met using harvested biomass, thereby drastically reducing import costs. Refinery costs accounted for the large majority of the remaining costs. A sensitivity analysis was also conducted to assess the effect of uncertainty associated with some economic and production parameters.

“…For bioethanol production, the effect of feedstocks and pre-treatment technologies on technoeconomics has been widely studied (Tao, et al, 2011) (Dickson, et al, 2018) (Mupondwa, et al, 2018). However, in the literature, there is lack of detailed cost analysis on immobilized cells and process types for bioethanol production.…”

Lignocellulosic ethanol production: Evaluation of new approaches, cell immobilization and reactor configurations

2019

The environmentally-friendly, economically-viable production of ethanol from cellulosic biomass remains a major contemporary challenge. Much work has been done on the disruption of cellulosic biomass structure, the production of enzymes for the conversion of cellulose and hemicellulose into simple sugars that can be fermented by bacteria or yeast, and the metabolic engineering of ethanol-producing microbes. The results of these studies have enabled the transition from laboratory to industrial scale of cellulosic ethanol production. Notably, however, current processes use free microbial cells in batch reactors. This review highlights the advantages of using immobilized and co-immobilized cells together with continuous bioreactor configurations. These developments have the potential to improve both the yield and the green credentials of cellulosic ethanol production in modern industrial settings.
