“…Forest biomass is all organic material of plant origin, coming from the different components of trees (leaves, branches, bark, stem and roots), in addition to being considered an alternative and renewable source of energy (AMORIM et al, 2021). According to Marcelino et al (2017), obtaining this forest biomass for energy use can occur from harvesting wood or using co-products generated during the harvest itself or in industries from wood processing.…”

The objective of this research was to characterize the energetic properties of the biomass of the bole and twig of clones of Eucalyptus spp. for direct burning and charcoal production. To characterize the wood of the bole and the branch, three trees were selected using the simple random method, from which discs with a thickness of 5 cm (base, middle and top), were obtained from these same trees and samples of the branch were obtained. The biomass of the bole and twig of Eucalyptus urophylla x Eucalyptus gradis presented acceptable characteristics for both direct burning and charcoal production. However, charcoal from bole biomass presented energy properties of total yield in charcoal (33.23%), fixed carbon content (63.50%), higher calorific value (7047.19 kcal/kg) and ash (0.23%) within the recommended range for quality charcoal. A carbonization rate of 500°C is recommended, as it presented a higher percentage of fixed carbon and consequently a higher calorific value and fixed carbon stock.

“…The source could be agricultural and forestry waste, sewage sludge from municipal WWTP, and MSW [100]. Moreover, Brazil has a vast production of agricultural and forestry waste [101], as well as WWTP sewage sludge and MSW [102][103][104], which also stand out as potential sources for biochar production.…”

Waste treatment and valorization have become crucial for sustainable development towards a circular economy. As an alternative, biochar production is a promising process to convert wastes into a valuable product that presents several potential applications to cope with environmental problems. Biochar in recent years has been the subject of many studies, which have leveraged the number of patents and the industrial interest in this process. Against this background, this overview aimed: (i) to identify the advances in biochar research; (ii) to assess the number of patents on biochar over the years; (iii) to look at the industrial production of biochar worldwide; (iv) to detect the potential for biochar production in Brazil regarding waste biomass availability; and (v) to discuss the potential of biochar in contributing to reach some Sustainable Development Goals (SDGs). The holistic analysis presented here suggests that progress has been made in research, patent development, and industrial implementation of biochar, and that its potential role in achieving certain SDGs is noteworthy. Therefore, this overview can be useful in guiding future research about biochar to improve the knowledge of the different branches in this field.

“…The strategies related to the technology to be used for the biomass conversion of orange wood into high-value products should be described in the literature for other lignocellulosic residues since the energy use of these residues is still recent. Thus, the most consolidated technological options in terms of bioenergy are the production of solid biofuels (briquettes and pellets) and coal [12]. These technologies aim to increase the energy density, avoiding the direct burning of waste, configuring themselves as a form of treatment of the waste, corroborating with the decrease in its flow and avoiding inadequate disposal.…”

The production of orange (Citrus sinensis) generates many residues, and the few that are used are usually by-products of the fruit juice processing industry. Among the residues, wood is potentially advantageous for use in bioenergy, but with few records in the literature. In this sense, this study sought to evaluate the feasibility of using orange wood for energy purposes by performing chemical characterization, immediate analysis, FTIR, calorific value, thermogravimetry and bulk and energetic densities for three compositions: 100% trunk (100T), 90% trunk + 10% bark (90T10B) and 100% bark (100B). 100T showed a higher fixed carbon content (16.76%) and equality with 90T10B in lignin, holocellulose, useful calorific value and volatile materials. 100B presented higher extractives and ash contents of 19.67% and 10.35%, respectively. The FTIR spectra and thermogravimetric curves were similar in 100T and 90T10B. 100B showed more stages of degradation and a higher incidence of peaks in the range 780–612 cm−1. The bulk density was equal in 100T and 90T10B, but the energy density was higher in 100T (6.16 Gj.m−3). 100T and 90T10B are good options for bioenergy and the chemical composition and thermal degradation of 100B point to new investigations in this composition.
