“…In addition to this study, a parallel study was conducted in which wood samples from E. benthamii , E. dunnii , and E. grandis were used to produce acetic acid and isopropanol ( Lopretti et al., 2016 ). These processes performed together would provide a more sustainable bioethanol production from these energy crops ( Balan, 2014 ; Cebreiros et al., 2017 ).…”

“…membrane, extraction, distillation) processes may allow the recovery of further by-products (e.g. nutrients, biochar, amino acids, organic acids) from the effluents of AD and DF processes (Cebreiros et al, 2017;Arora et al, 2018;Rajesh Banu et al, 2020;Uddin et al, 2021). Therefore, an accurate life cycle analysis (LCA), integrating energy balances and operating costs for each unit of the process, would be required to identify the best design, location, and size of the biorefinery plants in Colombia.…”

This study provides the first overview in Colombia on energy recovery potential by anaerobic digestion (AD) and dark fermentation (DF) of three different residual biomasses: coffee mucilage (CFM), cocoa mucilage (CCM), and swine manure (SM). First, AD and DF models were developed based on the ADM1 model. Then, simulated biogas production yields were compared to experimental data to validate the models. The results of comparative simulations indicate that energy recovery potentials from biogas for the different Colombian departments range from 148 to 48,990 toe, according to the local production amounts of CFM, CCM, and SM in 2017. The study provides crucial information that can be used to assess the best design, operation mode, and locations of AD and DF plants in Colombia. The results indicate that biogas production performances and energy recovery yields improve by increasing CFM/SM and/or CCM/SM ratios of the feed, and by increasing organic load from 2 to 26 gCOD∙l−1.

“…To this end, the forest sector and, more specifically, the pulp and paper industry, are searching for alternative, non-wood plant fibres (Mongkhonsiri et al 2018;Daya and Nourelfath 2019;Pio et al 2020). In addition, these industries are fostering research into the integral fractionation and biorefining of lignocellulosic materials to obtain a number of products in addition to pulp and energy by using processing schemes similar to those found in oil refining processes (Cherubini 2010;Zhu and Zhuang 2012;Nanda et al 2015;Cebreiros et al 2017). In theory, existing schemes for cellulose pulp production could be used at industrial plants for the conversion of lignocellulosic biomass into biorefinable fractions in order to increase profits in the forest and paper industries (Clark et al 2009;Vila et al 2011;Pätäri et al 2016;Rogers et al 2018).…”

It was proposed that pre-hydrolysing tule (Typha domingensis Pers) would make it possible to produce handsheets with strength-related properties similar to those of conventional commercial paper, in addition to valorizable hemicelluloses. The hypothesis was tested with a biorefining scheme involving autohydrolysis. Conditions were optimized to maximize the extraction of hemicelluloses while preserving glucan integrity. The autohydrolysis at a liquid to solid ratio of 13 at 141 °C for 45 min (optimized conditions) provided a commercially useful liquor containing primarily tule hemicelluloses. The autohydrolysis of tule before alkaline extraction made it possible to obtain a valuable liquid phase comprising between 23.3% and 71.6% of all hemicelluloses in the raw material. The gross heating value for the hydrolyzed tule was increased (1.6% to 7.9 %) with respect the raw material. The solid phase was subjected to soda–anthraquinone pulping. The yield, ethanol extractives, kappa number, viscosity, glucan, xylan, Klason lignin, soluble lignins, as well as the tensile index were evaluated. Tule was found to be amenable to industrial processing for the production of quality cellulose derivatives. Autohydrolysis provided valorizable liquor in addition to solid that yielded soda–anthraquinone pulp having properties similar to those obtained in its absence, but using milder operating conditions.
