“…This temperature range is normally attributed to cellulose degradation. Similar results to those obtained in the present work are found in the literature for varied sources of biomass (FERMANELLI et al, 2020;SANTOS, R. C. DOS et al, 2012). The use of the eucalyptus harvest residue is still a source of biomass to be better explored.…”

“…Furthermore, the temperature of the analysis did not exceed 450 °C, since this range is suitable for the efficiency of the slow pyrolysis process when the solid phase (biochar) is targeted. Beyond that temperature, it is expected that there will be no further degradation of hemicelluloses and cellulose, and the residual mass can be attributed almost entirely to lignin (FERMANELLI et al, 2020). Results for thermal degradation of wood from four eucalyptus hybrids reported in (SANTOS, R. C. DOS et al, 2012) are similar to that of the residue and its fractions analyzed in this work.…”

“…It is also noted, through the data in Table 1, the high content of volatile material (81.1%) and fixed carbon (15.0%) for the residue. Compared with data from the literature (FERMANELLI et al, 2020) for three other biomass residues, the following values are found for volatile matter and fixed carbon respectively: 53.80% and 17.01% for rice husk, 70.03% and 23.18% for peanut shell, 64.47% and 16.54% for wheat straw. Thus, it can be seen that the data obtained in the present study demonstrate the feasibility of the residual biomass from the eucalyptus harvest to the thermal conversion processes.…”

“…of the dry biomass composition, which explains the higher peak intensity in the DTA graph about 350 °C (YANG, H. et al, 2007). The absence of a specific peak for lignin may be related to the fact that this biopolymer undergoes slow degradation over a wide temperature range, which varies from 150 to 900 °C, as a result of its high thermochemical stability (FERMANELLI et al, 2020;YANG, H. et al, 2007). Also, the low rate of mass loss of lignin normally results in a high yield of solid products from the pyrolysis process (QUAN; GAO; SONG, 2016).…”

Considering the increasing need for renewable products, the present work aims to evaluate the physical-chemical properties of the eucalyptus harvest residues and its constituent fractions individually (barks, leaves, and branches), through proximate, ultimate, energetic and thermal analyzes. The biomass studied was Eucalyptus saligna species, cultivated mainly for the production of pulp and paper. The proximate analysis of the residue resulted in the moisture content of 10.1%, ash content of 3.9%, volatile materials about 81.1%, and fixed carbon of 15.0%, showing similar values to the constituent fractions. The ultimate analysis of the residue resulted in 46.5% of carbon content, 5.8% of hydrogen, and 43.2% of oxygen. The high heating value (HHV) for the residue is 17.93 MJ/kg, comparable to other biomasses of importance, including eucalyptus wood, the noblest part of the forest cultivation. The thermogravimetric (TGA) and differential thermal analysis (DTA) were carried out and the resulting thermograms show three main ranges of biomass degradation. The first range, from 30 to 150 °C, corresponds to the drying of the material; in the range from 200 to 325 °C hemicelluloses degrade, with partial degradation of lignin and cellulose, and in the range from 325 to 380 °C, the majority of cellulose degradation takes place. The physical-chemical data demonstrate that the eucalyptus residue is an excellent source of biomass for thermal conversion processes. Obtaining products with higher added value from this residue contributes to the implementation of new technological practices that link economic development to environmental responsibility.

The purpose of this work was to valorize a regional biowaste through a modest thermo-catalytic pyrolysis process. ZSM-11 zeolites modified by Ni incorporation (1–8 wt%) where synthesized and characterized by means of X-Ray Diffraction, Inductively Coupled Plasma Atomic Emission Spectroscopy, Infrared Fourier Transform Spectroscopy, UV–vis Diffuse Reflectance Spectra and Temperature Programmed Reduction. Results demonstrated that Ni was mainly incorporated as oxide. These porous materials were evaluated as heterogeneous catalysts to improve biooil composition. In this sense, higher hydrocarbon yields and quality chemicals were obtained and oxygenates were diminished. The deactivation of the most active material was studied over six cycles of reaction. In order to achieve the circular bioeconomy postulates, the obtained biochar (usually considered a residue) was further valorized through a physicochemical activation. The obtained activated biochars were extensively characterized.

Despite their high persistence in the environment, organochlorines (OC) are widely used in the pharmaceutical industry, in plastics, and in the manufacture of pesticides, among other applications. These compounds and the byproducts of their decomposition deserve attention and efficient proposals for their treatment. Among sustainable alternatives, the use of ligninolytic enzymes (LEs) from fungi stands out, as these molecules can catalyze the transformation of a wide range of pollutants. Among LEs, laccases (Lac) are known for their efficiency as biocatalysts in the conversion of organic pollutants. Their application in biotechnological processes is possible, but the enzymes are often unstable and difficult to recover after use, driving up costs. Immobilization of enzymes on a matrix (support or solid carrier) allows recovery and stabilization of this catalytic capacity. Agricultural residual biomass is a passive environmental asset. Although underestimated and still treated as an undesirable component, residual biomass can be used as a low‐cost adsorbent and as a support for the immobilization of enzymes. In this review, the adsorption capacity and immobilization of fungal Lac on supports made from residual biomass, including compounds such as biochar, for the removal of OC compounds are analyzed and compared with the use of synthetic supports. A qualitative and quantitative comparison of the reported results was made. In this context, the use of peanut shells is highlighted in view of the increasing peanut production worldwide. The linkage of methods with circular economy approaches that can be applied in practice is discussed.
