“…Utilization of municipal wastes for GTL is interesting in that approximately one-third of all food prepared for human consumption goes to waste, leading annually to ca. 1.3 billion tons of potential feed for GTL that would otherwise be buried or incinerated . Some commercial operations have begun to explore the concept of valorizing municipal waste streams, such as Enerkem in Quebec and Fulcrum Bioenergy in California. , …”

Synthesis gas (syngas), composed primarily of H2 and CO, can be produced from fossil resources, municipal solid waste, biogas, and terrestrial biomass and can be converted into oxygenated intermediates such as alcohols and aldehydes through both catalytic and biological routes. These oxygenates serve as precursors for the downstream production of fuels and chemicals. However, since these processes all proceed through syngas regardless of the feedstock, renewable resources do not offer any inherent chemical advantage over fossil resources, and the process economics is largely dictated by (i) the spread between feedstock cost and the cost of petroleum (the dominant existing feedstock for fuel and chemical production) and (ii) the conversion efficiency, in terms of both energy and carbon, normalized by capital costs. Thus, lower-cost renewable feedstocks and improved conversion efficiencies combined with policy incentives could enable increased incorporation of biocontent into fuels and chemicals through syngas-derived oxygenates. To that end, this review assesses recent advancements in heterogeneous catalysis for the downstream conversion of syngas-derived oxygenates (i.e., methanol, ethanol/C2+ alcohols, and aldehydes) to fuels and chemicals, specifically seeking to link how these advancements improve the overall conversion efficiency. In the long term, these catalysis advancements can expand the window of market conditions over which these syngas pathways are economically viable, creating an opportunity to “piggyback” on existing and future natural gas to liquids installations by cofeeding renewable feedstocks.

“…2 The use of lignocellulosic agricultural residues, which do not compete with food, and food supply chain (FSC) wastes, can help create flexible zero-waste networks. 3 Utilizing such wastes can result in the creation of inventive ranges of products that can satisfy the needs of both established and emerging sectors. 3 There is a wide range of lignocellulosic materials that are suitable feedstocks for a biorefinery, with different concentrations of lignin, cellulose, and hemicellulose.…”

“…This work will contribute to the introduction of these products as green and efficient alternatives for combatting neglected tropical diseases that ravage people in several parts of the world. Sugarcane bagasse was chosen as the raw material due to its availability in certain countries, such as Brazil and India [ 17 ]. The use of the hemicellulosic fraction to obtain the BS was emphasized in the present work because the integral exploitation of lignocellulosic biomass is needed to consolidate biorefineries [ 18 ].…”

Biosurfactants produced by Scheffersomyces stipitis cultured in sugarcane bagasse hydrolysate as new green larvicides for the control of Aedes aegypti, a vector of neglected tropical diseases

Biosurfactants are microbial metabolites with possible applications in various industrial sectors that are considered ecofriendly molecules. In recent years, some studies identified these compounds as alternatives for the elimination of vectors of tropical diseases, such as Aedes aegypti. The major bottlenecks of biosurfactant industrial production have been the use of conventional raw materials that increase production costs as well as opportunistic or pathogenic bacteria, which restrict the application of these biomolecules. The present study shows the potential of hemicellulosic sugarcane bagasse hydrolysate as a raw material for the production of a crystalline glycolipidic BS by Scheffersomyces stipitis NRRL Y-7124, which resulted in an emulsifying index (EI24) of 70 ± 3.4% and a superficial tension of 52 ± 2.9 mN.m-1. Additionally, a possible new application of these compounds as biolarvicides, mainly against A. aegypti, was evaluated. At a concentration of 800 mg.L-1, the produced biosurfactant caused destruction to the larval exoskeletons 12 h after application and presented an letal concentration (LC50) of 660 mg.L-1. Thus, a new alternative for biosurfactant production using vegetal biomass as raw material within the concept of biorefineries was proposed, and the potential of the crystalline glycolipidic biosurfactant in larvicidal formulations against neglected tropical disease vectors was demonstrated.
