“…Commonly, drying processes are performed to reduce the moisture of the biomass, this process can be done in the sun and in ambient conditions [29,31,39] or in a greenhouse [13,28]. Another common procedure is the grinding or crushing of the biomass in machines, such as hammer and knife mills [13,40] before particle size classification through sieves.…”

The densification of raw material into fuel briquettes is one of the routes to convert biomass into energy. This method provides uniformity to the solid fuel, better physical and energy properties, facilitating its storage and transport, in addition to more homogeneous combustion. Given the importance of these characteristics, this work presents a literature review, emphasizing the experimental levels of the variables of the briquetting process, as well as on the most relevant quality parameters for obtaining briquettes. We also carry out a survey of the main technologies used in the production of briquettes, as well as the experimental methodologies and statistical analysis used in the planning and validation of processes. It was observed among the studies that the raw material granulometry, followed by pressure, initial moisture, compaction time and binder are the most used process variables for the production of briquettes. Other factors, such as the proportion of biomass, process temperature and thermal pre-treatments are used to obtain greater energetic and physical responses. Among the works, divergences were observed regarding the relevance and interaction of some process variables on the quality variables of the briquettes, indicating the need for the experiments to be mathematically modeled.

“…In the study "Briquette Production for Use as a Power Source for Combustion, Using Charcoal Thin Waste and Sanitary Sewage Sludge," the authors describe the relationship between heat lost from the fuel and the heat of the water; thus Eqs. 5 and 6 show the calculations for both variables, including some theoretical values [21].…”

An energy model focuses on the sustainability of environmental proposals that use clean biomass technology. In this case, briquette production seeks to generate socio-environmental development in agricultural areas contaminated by the burning of rice husks. However, this agricultural waste product has a large heating capacity and can be used as a raw material for briquette production, replacing conventional contaminant fuels such as firewood and reducing Peru's annual energy consumption by approximately 833,000 kg of CO 2 per year, considering the minimization of emissions from the felling of trees and the burning of rice husks. These rice husks are burned and generate pollutant gases, causing respiratory and pulmonary problems. Despite these negative effects, it is an agricultural waste product with great untapped energy potential and constitutes an opportunity to promote socio-environmental development based on economic valorization. The level of deforestation would decrease by approximately 2070 trees per year, 23% of a market population which consumes 10 kg of firewood per day. Unlike similar projects, briquette production sustainability may be achieved when economic, environmental and social aspects are included in energy model development, based on the application of clean technology and efficient management of energy supplies, such as husk supplies and corresponding briquettes.

“…Nitrogen compounds usually result from dehydration reactions of peptide bonds emanating from protein fraction of the sewage sludge [ 48 ]. The presence of carboxylic group, according to a previous study, is said to influence the thermal strength of a biomass due to hydrogen interaction [ 49 ]. Figure 4 presents the infrared spectra of raw sugarcane bagasse torrefied at various temperatures.…”

Improving the Solid Fuel Properties of Non-Lignocellulose and Lignocellulose Materials through Torrefaction

et al. 2021

Biomass torrefaction is a thermal pre-treatment technique that improves solid fuel properties in relation to its efficient utilization for energy generation. In this study, the torrefaction performance of sewage sludge, a non-lignocellulose biomass and sugarcane bagasse, a lignocellulose biomass were investigated in an electric muffle furnace. The influence of torrefaction temperature on the physiochemical properties of the produced biomaterial were examined. Characterization of the raw and torrefied biomass material were studied using thermogravimetric analysis, Fourier transform infrared spectroscopy (FTIR) analysis and scanning electron microscopy. From the result obtained, it was evident that an increase in torrefaction temperature up to 350 °C caused a 33.89% and 45.94% decrease in volatile matter content of sewage sludge and sugarcane bagasse, respectively. At a higher temperature of 350 °C, the peak corresponding to OH stretching of hydroxyl group decreased in intensity for both biomasses, showing a decomposition of the hydroxyl group as a result of torrefaction. This enriched the lignin content of the torrefied samples, thus making these solid fuels good feedstock for energy production.
