abstract = {Biogas generation through anaerobic digestion provides an interesting opportunity to valorize some types of animal waste materials whose management is increasingly complicated by legal and environmental restrictions. To successfully expand anaerobic digestion in livestock areas, operational issues such as digestate management must be addressed in an economical and environmentally sustainable way. Biogas upgrading is another necessary stage before intending it to add-value applications. The high concentration of CO2 in biogas results in a reduced caloric value, so the removal of CO2 would be beneficial for most end-users. The current work evaluates the CO2 uptake properties (thermogravimetry study) of low-cost adsorbent materials produced from the animal wastes generated in the livestock area itself, specifically via pyrolysis of poorly biodegradable materials, such as meat and bone meal, and the digestate from manure anaerobic digestion. Therefore, the new element in this study with respect to other studies found in the literature related to biochar-based CO2 adsorption performance is the presence of high content of pyrolyzed proteins in the adsorbent material. In this work, pyrolyzed chars from both meat and bone meal and co-digested manure have been proven to adsorb CO2 reversibly, and also the chars produced from their representative pure proteins (collagen and soybean protein), which were evaluated as model compounds for a better understanding of the individual performance of proteins. The ultra-microporosity developed in the protein chars during pyrolysis seems to be the main explanation for such CO2 uptake capacities, while neither the BET surface area nor N-functionalities on the char surface can properly explain the observed results. Although the CO2 adsorption capacities of these pristine chars (6–41.0 mg CO2/g char) are far away from data of commercially activated carbons ($sim$80 mg CO2/g char), this application opens a new via to integrate and valorize these wastes in the circular economy of the primary sector.},

abstract = {Using lignocellulosic char instead of the original biomass avoids the need for costly cleaning and conditioning stages of the producer gasification gas. However, lignocellulosic char gasification has been less extensively studied than gasification of lignocellulosic biomass, and a review of published works on this topic was missing. In this review the present status of char gasification technologies and their future prospects are critically discussed, including possible research opportunities. To date, most studies on char gasification have been performed in thermogravimetric analyzers (TGA) or TGA-like experimental setups. The major setback of TGA and TGA-like equipment is that they do not mimic the actual reaction conditions occurring in gasification reactors, which impedes a direct extrapolation of the findings during the scale-up of different gasification technologies. For this reason, in this literature review focus was put on studies undertaken in industrially relevant reactors, both in batch and continuous configurations. Overall, char gasification can be deemed a valid alternative for clean syngas production, contributing to an integral valorization of lignocellulosic residues within different biorefinery schemes. Of these, process intensification by microwave heating offers interesting opportunities for research and scaling-up, though efforts must be directed toward developing continuous microwave-assisted gasification processes.},

abstract = {Black liquor obtained from semichemical pulping of barley straw was depolymerized in a stirred autoclave reactor, at temperature in the range of 250–300 °C while varying the amount of catalyst (zeolite Y). Three fractions were obtained from the depolymerized liquor: a fraction directly extracted from the liquid with isopropyl acetate (L$alpha$), a second one which contains the heaviest compounds precipitated from the liquid at pH 1 (L$beta$) and a third one obtained by extraction of the acidified liquid (L$gamma$). The three fractions were tested as antioxidant additives for biodiesel, blending them individually at a dosage of 1 wt%. The antioxidant activity was L$alpha$ > L$gamma$ > L$beta$. The L$alpha$ fraction showed the highest antioxidant activity, increasing the oxidation stability time over neat biodiesel from 150 to 250%. The phenolic volatile content of the fractions (measured by GC/MS) decreased in the same rank (L$alpha$ > L$gamma$ > L$beta$), so there doesn't seem to be correlation between the volatile content and the increase of antioxidant activity. Depolymerizarion temperature was the most influential parameter, showing a clear positive effect on the antioxidant activity for the three fractions.},
