“…One interesting example is sugarcane-producing mills which find its residue, sugarcane bagasse, a reliable and affordable source of thermal and power generation for auto-consumption needs with an installed capacity between 10 and 50 MW. Sugarcane has 16% of fiber or bagasse (dry basis) with almost 9% of lignin ( [1,6,18]; see Figure 5). Then, we estimated the potential energy supply considering a caloric value of 19.1 GJ/ton for sugarcane bagasse (see Table 1 and Figure 7).…”

Energy transition toward low carbon, high sustainable and efficient generation and distribution systems will change the supply matrix of the world and create new opportunities but challenges still remain. Energy generation from biomass, or bioenergy, is one of such renewable sources and its use might be generalized in the following years. Bioenergy is a very promising strategy to provide energy not only for mobility but also for onsite places for heat and power generation. Besides, bioenergy differentiates from other renewable energies that biomass may be the source of a myriad of molecules enabling the bio-based economy and allowing the replacement in an extent of solvents, petrochemicals, and polymers produced by the petroleum industry. Biomass is generally composed of some large polymers found in nature such as cellulose, hemicellulose, proteins, starch, chitin, and lignin. The latter is a complex phenylpropanoid biopolymer conferring mechanical strength to plant cell walls and one of major spread in nature along with cellulose and chitin. Lignin has a plenty of potential uses in modern bio-based economy, from conventional paper industry uses to more challenging conversion to useful chemicals, materials, and clean biofuels. This chapter undertakes a rapid overview on lignin applications in order to describe the basis of a lignin-based economy.

“…Some initial efforts have been made to estimate the theoretical potential of lignocellulosic biomass from agriculture, and in turn, bioethanol production from different biomasses, e.g. 150 × 10 6 L/year using Agave bagasse (residue from Tequila production) and 5200 × 10 6 L/year using sugarcane bagasse . These estimates could not be accurate because the biomass potentials were calculated based on residue ratios for cultivars that do not necessarily reflect the Mexican context .…”

Mexico is one of the largest agricultural producers in Latin America and generates a large amount of agricultural residue. The aim of this study was to establish the usefulness of four of the main Mexican crops (corn, wheat, sugarcane, and Agave) as feedstock for lignocellulosic bioethanol production. The lignocellulosic residue ratio (RR), defined as weight of residue (in tons) per ton of product, was measured by sampling crop fields in 11 geographic regions of Mexico. The chemical composition, assessed by Fourier-transform infrared spectroscopy (FTIR) and carbon-13 nuclear magnetic resonance ( 13 C NMR), and structural composition (extractives, cellulose, hemicellulose, and lignin contents), heating value, and metal content of these lignocellulosic residues were measured. Biorefinery locations, and their theoretical bioethanol production, were suggested using the gravity center method and techno-economic criteria. The highest RR (1.1 ton of straw per ton of grain) was obtained for wheat straw followed by corn 1144

“…As there is no established biomass market, an average biomass cost of $35 t −1 was considered based on values reported in a local study, where the price ranged from $6 to 65 t −1 depending on the logistics . Biomass prices have been reported to be lower in Mexico than in the USA, with feedstocks such as sugarcane and blue agave bagasse selling for values between $16 and 39 t −1 . Labor, energy, biomass, and ethanol prices were based on the Mexican context and others were as per SuperPro Designer or Internet sources.…”

This work presents techno-economic and greenhouse gas (GHG) analyses of an ethanol biorefinery integrating lignin conversion into eugenol and other phenolics. Catalytic hydrogenolysis assisted by isopropanol (IPA) is used to convert the lignin recovered after ionic liquid (IL) pretreatment, saccharification, and fermentation. This process was compared to a biorefinery using lignin for energy generation and simulated in SuperPro Designer. Spatial analysis was performed to determine biorefinery locations and capacities in a Mexican state with potential for lignocellulosic biomass, including corn stover, sorghum stubble, and Jatropha fruit shells. Relative to the base case, diverting 50% of lignin to phenolics decreased the ethanol cost of production significantly due to the high market value of the co-products. The minimum ethanol selling price (MESP) for this case was $2.02 gal −1 . The resulting cradle-to-gate GHG footprint of bioethanol was 21 g CO 2 -eq MJ −1 , a 78% reduction with respect to gasoline when system expansion is used for allocation. Using market value-based allocation resulted in 82% GHG reduction. Analysis of scenarios showed that a biorefinery processing 3000 t day −1 biomass and diverting 80% of lignin to phenolics can potentially yield an MESP lower than $1.5 gal −1 . To achieve this, research should target a reduction in IL input by 30% and IPA input by 40%, together with more energy-efficient separation processes. The reduction in IL and IPA can be achieved by decreasing their loading rates and increasing recycling. Sensitivity analysis showed that, 979Modeling and Analysis: Lignin valorization to eugenol and phenolic products in integrated biorefineries E Martinez-Hernandez et al.for biomass prices higher than $45 t −1 , biorefinery capacities must exceed 5000 t d −1 biomass input.
