Turning waste CO2 into value-added biorefinery co-products using cyanobacterium Leptolyngbya sp. KC45 as a highly efficient living photocatalyst

Industrial Symbiosis: CO2 Utilization by Producing Disodium Octaborate Tetrahydrate and Baking Soda from Borax

“…On the other hand, supported by late technological achievements, alternatively using CO 2 as a chemical raw material through what is known as CO 2 capture, utilization, and sequestration (CCUS) processes offers substantial benefits, − for example, higher energy and material productivity and a reduction in the consumption of fossil fuels, the formation of pollutants, or the usage of harmful chemicals. ,− In fact, the US National Academies of Sciences, Engineering, and Medicine strongly recommends widespread deployment and adaptation of CCUS systems by governments and industries to ensure not only a circular economy but also permanently locking CO 2 in stable products while creating economic as well as environmental values…”

Value-added green biorefinery co-products from ultrasonically assisted DES-pretreated Chlorella biomass

“…Although microalgae hold immense promise as primary contributors to alternative renewable feedstocks, the majority of chemical production processes utilizing microalgal biomass have centered around a singular product, with predominant research efforts directed towards biofuels [14] . Considering a conservative estimation of 25 % extractable oil from microalgal biomass, the production of one metric ton of biodiesel results in three times the quantity of lipid extracted microalgal biomass residues (LMBRs) [15] .…”

“…Recently, there has been a growing interest in exploring cascading bio-refineries to fully optimize the inherent value of all components found in microalgae biomass. An approach that shows promise and widespread acceptance for maximizing the utilization of microalgal biomass to create high-value co-products while preserving essential characteristics is the waste-free biorefining strategy [14] . Despite extensive research on microalgal biomass-based biorefineries, none of these studies have investigated the feasibility of utilizing Chlorella biomass to simultaneously produce biodiesel with desired fuel properties and hydroponic biofertilizer.…”

Bioprocessing and Fermentation Technology for Biomass Conversion

“…Biomass is defined as any organic material derived from plants and animals. It is an abundant renewable resource and encompasses a wide range of feedstocks, including agricultural residues and forest waste [2], algae [3][4][5], cyanobacteria [6][7][8], and even foodindustry-related or municipal solid wastes [9,10]. However, effectively harnessing the energy within this diverse resource poses significant challenges.…”

“…In particular, converting organic waste such as agricultural residues (e.g., corn stover, wheat straw), forestry litters (e.g., wood chips, sawdust), and various industrial and food wastes [10,14,15] into valuable products helps to reduce the environmental impact of waste disposal and facilitate nutrient recycling. Biomass can be transformed into a range of valuable products, including biofuels, biogas, chemicals, bio-based materials, and even biopharmaceuticals [2,4,[6][7][8][9]16,17]. This adaptability enables the efficient utilization of biomass across diverse industries.…”
