“…We found out that a vast number of authors apply LCA to determine only the environmental impacts of SBF energy systems [20][21][22][23][27][28][29][30][31][32]. However, fewer authors incorporate elements of the economic dimension along with environmental impacts through technical-economic assessments (TEA) of the use of AIR for heat generation [19,25,33,34]; this last article presents the TEA of current use of orange peels and the potential use of sugarcane straw to generate heat from a fruit-processing facility in Mexico. Moreover, few articles analyze three sustainability dimensions: the social, economic, and environmental dimensions of energy systems that use SBF-AIR were found.…”

Motivated by the environmentally driven energy transition we live in, the valorization of biomass residues from the agro-industry as renewable energy can play an essential role in GHG emissions mitigation. To overcome the debate on the production and use of solid biofuels (SBF), in this study, we apply an integrated multicriteria tool for the assessment of the sustainability use of agro-industrial residues (AIR) as solid biofuels. Mexico has a vast AIR production, but frequently, the AIR are considered waste biomass. Still, when valorized, SBF do not have adverse effects on soil quality, are not responsible for biodiversity loss, and compete against food production as first-generation SBF. Nevertheless, the AIR present other environmental, social, and economic impacts that have not been adequately evaluated; therefore, we identified the need for a sustainability assessment of energy systems based on the use of SBF–AIR as input fuels. After reviewing previous work on sustainability assessment methodologies, multicriteria decision analysis methods, and indicator weighting methods, we considered it appropriate for this problem to apply a tool that integrates the entropic indicator weighting method into the discrete multicriteria decision analysis method called PROMETHEE. In terms of selected sustainability indicators, this tool was used to assess four electric energy supply systems of a Mexican sugar mill as a case study: current bagasse cogeneration, efficient bagasse cogeneration, a power generation system fueled only with fuel oil, and grid electricity only. Finally, after evaluating the mentioned energy systems with four sustainability indicators: GHG emissions, PM emissions, employments per energy unit (JOBS), and the net present value (NPV) of each alternative, we found the net outranking flow of the efficient bagasse system (EBS). which is the most sustainable system because it has the highest outranking flow value from the four considered alternatives, since it has the lower GHG emissions, reducing the current bagasse GHG emissions by 55% and the PM emissions by 58%. The EBS also shows the highest NPV system due to surplus electricity sales, resulting in the most profitable energy system analyzed.

“…Citrus peel residues have, however, high potential in terms of biorefining [12], and are a promising and sustainable option as their production does not compete with food or animal feed [13,14]. These residues can be used to generate bioelectricity and produce liquid biofuels [10], biogas production [14], heat and power generation-CHP- [15], and can be used for direct combustion [16] or in the form of pellets [11,15].…”

Solid Biofuels Scenarios from Rural Agricultural and Forestry Residues for Mexican Industrial SMEs

In Mexico, as in the rest of the world, the industry sector is frequently highly dependent on fossil fuels; in addition, energy transformation processes are not very efficient and scarcely oriented towards climate change mitigation. Given these facts, solid biofuels (SBFs) from agricultural and forestry residues from rural areas may represent an alternative that contributes to the decarbonization of the industrial sector, especially in Small- and Medium-Sized Enterprises (SMEs). From an economic and climate change mitigation perspective, this study evaluates harnessing SBFs in SMEs related to lime, bricks, dairy products, craft beer, and artisanal mezcal (a well-known Mexican distilled alcoholic beverage), products mainly manufactured in rural areas of Mexico. For each of these SMEs, we constructed two energy consumption scenarios that span from 2018 to 2050. On the one hand, a baseline scenario (BS) that reflects the behaviour of historical energy consumption in Mexico and, on the other hand, an alternative scenario (AS) that proposes the use of SBFs with modern and efficient technologies and sustainable inputs of agricultural and forestry residues originated mainly from rural areas. According to our results, a comparison between the two scenarios reveals that two out of five SMEs industrial niches studied, appear with mitigation costs in the AS namely brick kilns, and limekilns SMEs that have mitigation costs of 9.99 and 19.74 USD/tCO2e, respectively, primarily due to the high investment cost of the new MK2 kilns and the relatively high cost of pellets, respectively. Since these niches have high mitigation potentials (7.77 MtCO2e for brick kilns and 2.83 MtCO2e for limekilns), their implementation requires adequate incentives and financing. On the contrary, the dairy, craft beer, and mezcal SMEs niches have negative mitigation costs (−14.30, −10.68, −0.98) USD/tCO2e, mainly due to the high savings in the cost of fossil fuels and their materialization, especially for the mezcal niche which has a mitigation potential of 2.97 MtCO2e, requires only an adequate regulatory and normative framework. We conclude that using commercial SBFs (pellets, briquettes, and traditional firewood) in SMEs niches contribute to generating formal markets with adequate distribution channels, both for SBFs and sustainable residual biomass inputs (residual firewood, agave bagasse, and spent barley grain). This alternative scenario also promotes the creation of green jobs in agricultural and forestry areas, adding an economic value to residual biomass inputs not previously considered and contributing to the social development of rural areas.

“…Navarro-Pineda et al [10] made an LCA and technoeconomic analysis of using orange peels and sugarcane straw co-firing for industrial steam generation, as an alternative of using heavy fuel oil. The mitigation potential in several environmental categories, including GWP, was estimated in 34-63%, with an added benefit of decreasing the levelized cost of energy in about 20%.…”
