Abstract:
Biofuel production from microalgae biomass has been considered a viable alternative to harmful fossil fuels; however, challenges are faced regarding its economic sustainability. Process integration to yield various high-value bioproducts is implemented to raise profitability and sustainability. By incorporating a circular economy outlook, recirculation of resource flows is maximized to yield economic and environmental benefits through waste minimization. However, previous modeling studies have not looked into the opportunity of integrating productivity reduction related to the continuous recir

Abstract:
Hyaluronic acid (HA) is a polysaccharide of alternating d-glucuronic acid and N-acetyl-d-glucosamine residues present in the extracellular matrix of connective, epithelial, and nervous tissues. Due to its singular hydrating, rheological and adhesive properties, HA has found numerous cosmetic and medical applications. However, techno-economic analyses of high value-added bioproducts such as HA are scarce in the literature. Here, we present a techno-economic analysis of a process for producing HA using Streptococcus zooepidemicus, simulated in SuperPro Designer. In the baseline scenario, HA is p

The high energy consumption in Iran, particularly in the transportation sector, has contaminated large cities and jeopardized the society health. Therefore, in this study technical and economic features of the production of biodiesel plant in Iran from various wastes are investigated. Based on the Analytic Hierarchy Process (AHP) method’s findings, the southern area of Iran is selected for establishing the biodiesel plant in Iran.

Abstract:
Heterotrophic or autotrophic? This is the continuous question the industry faces when microalgae production is the endeavor. Surprisingly, nowadays specialists have not reached a consensus on which is the most economical option. The current work analyses costs for heterotrophic and autotrophic cultivation of microalgae at an industrial scale. Heterotrophic cultivation of microalgae results in a production cost of 4.00 €⋅kg− 1 of dry weight as a centrifuged paste. This is within the range of autotrophic costs, but still above the production cost in some photobioreactors. The stu

Sophorolipids (SLs) are microbial biosurfactants with an important role in industry and a continuously growing market. This research addresses the use of sustainable resources as feedstock for bioproducts. Winterization oil cake (WOC) and molasses are suitable substrates for SLs via solid-state fermentation (SSF). The model proposed herein was established for annually processing 750 t of WOC and comparing three support materials: wheat straw (WS), rice husk (RH), and coconut fiber (CF). Production capacity ranged 325–414 t of SLs per year. Unit Production Cost was 5.1, 5.7, and 6.9 USD/kg SL f

The use of Spirulina platensis for human consumption, due to the wide benefits gained as higher protein content, low calories, and high nutritional value, grows every year. Besides, several studies have tested alternative culture media to increase the level of biomass density and protein content, besides reducing the costs of production. Glucose (GLC) is a known component used to provide cell growth because it increases the carbon content of microalgae; however, there is no record of the use of the fetal bovine serum (FBS), a supplement widely used for animal cell culture.

In addition to producing bioenergy and molecules with high added value, microalgae have been recognized as an efficient microorganism for wastewater treatment. However, a major obstacle preventing its widespread use is the high energy cost of pretreatment, cultivation and downstream processes. Different types of wastewaters have been tested as culture mediums for microalgal biorefinery system.

Background: The global market for algae-based food and feed supplements is well-established and growing rapidly. The sector has grown fivefold since 2000. While microalgae products still hold a modest market share, the large-scale commercial production of microalgae as a primary source of proteins, lipids, carbohydrates, and other compounds remains in its early developmental stages. If successfully mass-produced, microalgae could make a significant contribution to global food and feed security.

Abstract:
Poultry livestock profitability significantly depends on feed, accounting for 60–70% of the total production cost, of which protein sources are among of the most expensive ingredients. The maintenance of profitability while meeting feed demand and reducing the environmental impact represents a considerable challenge driving research of alternative protein sources (APS), such as insects and algae meals. This study employs, for the first time, techno-economic assessment (TEA) methodology to evaluate the technological performance and the industrial feasibility of an APS-based poultry feed product

Abstract:
Microalgae are a potential means of recycling CO2 from industrial point sources. With this in mind, a novel photobioreactor (PBR) was designed and deployed at a coal-fired power plant. To ascertain the feasibility of using waste heat from the power plant to heat algae cultures during cold periods, two heat transfer models were constructed to quantify PBR cooling times. The first, which was based on tabulated data, material properties and the physical orientation of the PBR tubes, yielded a range of heat transfer coefficients of 19–64 W m−2 K−1 for the PBR at wind speeds of 1–10 m s−1.

Abstract:
The usage of microalgae has achieved critical importance for an environmentally sustainable society. Microalgae biomass can be transformed to third-generation biofuels by thermal, chemical, and biological processes. Growing algae for energy purposes, however, is still controversial in terms of long-term viability and economic viability. As a result, the majority of microalgae biomass is produced for high-value applications. The goal of this research is to conduct a techno-economic analysis of the production of bioproducts from microalgae. The study also intends to improve algae-based wastewa

Abstract:
Algae, photosynthetic organisms ranging from microscopic to macroscopic forms, play a critical role in carbon sequestration, oxygen production, and maintaining aquatic ecosystem balance. Their extensive applications in pharmaceuticals, biofuels, and bioproducts have positioned algae cultivation as a promising solution for sustainable resource production. Both microalgae and macroalgae can be cultivated using open systems (e.g., longline culture, floating nets, bottom culture, raceway ponds, and saline aquaculture) and closed systems (e.g., photobioreactors, tank cultures, and fermenters).
