The application of other processes, such as torrefaction and briquetting, can increase the profits from the use of agro-industrial waste for energy generation. Briquetting is an alternative for using these wastes, allowing the compaction of the biomass, generating a biofuel with high energy density, and which is more homogeneous and easier to store and transport. The objective of this study was to evaluate the physical and chemical properties of four biomass types (wastes from sawed eucalypt and pine wood, coffee pruning wastes, and sugarcane bagasse) torrefied at 300 \u00b0C and compacted (briquetting) at pressures of 6.21, 8.27, and 10.34 MPa. The torrefaction increased the fixed carbon content, ash, and calorific value, and reduced the volatile material content and hygroscopic equilibrium moisture of the biomasses. The volatile material content was lower and the fixed carbon higher in the coffee pruning waste, the ash content higher in the sugarcane bagasse, and the calorific value higher in the pine and eucalypt wood. The briquetting and the torrefaction processes increased the biomass bulk density, and the useful calorific value, respectively, and consequently the energy density of the briquettes produced with torrefied raw material under high pressure. The mechanical properties of the briquettes produced with all materials increased with the compaction pressure. Torrefaction and briquetting increased the energy potential of the biomasses evaluated to produce energy from clean technology.<\/jats:p>","DOI":"10.3390\/f11121272","type":"journal-article","created":{"date-parts":[[2020,11,29]],"date-time":"2020-11-29T21:00:57Z","timestamp":1606683657000},"page":"1272","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Potential of Briquette Produced with Torrefied Agroforestry Biomass to Generate Energy"],"prefix":"10.3390","volume":"11","author":[{"given":"Gabriel","family":"Reis Portilho","sequence":"first","affiliation":[{"name":"Department of Forestry Engineering, Federal University of Vi\u00e7osa, Vi\u00e7osa 36570-900, Brazil"}]},{"given":"Vinicius","family":"Resende de Castro","sequence":"additional","affiliation":[{"name":"Department of Forestry Engineering, Federal University of Vi\u00e7osa, Vi\u00e7osa 36570-900, Brazil"}]},{"given":"Ang\u00e9lica","family":"de C\u00e1ssia Oliveira Carneiro","sequence":"additional","affiliation":[{"name":"Department of Forestry Engineering, Federal University of Vi\u00e7osa, Vi\u00e7osa 36570-900, Brazil"}]},{"given":"Jos\u00e9","family":"Cola Zanuncio","sequence":"additional","affiliation":[{"name":"Department of Entomology\/BIOAGRO, Federal University of Vi\u00e7osa, Vi\u00e7osa 36570-900, Brazil"}]},{"given":"Antonio","family":"Jos\u00e9 Vinha Zanuncio","sequence":"additional","affiliation":[{"name":"Institute of Agricultural Sciences, Federal University of Uberl\u00e2ndia, Monte Carmelo 38500-000, Brazil"}]},{"given":"Paula","family":"Gabriella Surdi","sequence":"additional","affiliation":[{"name":"Department of Forestry Engineering, Federal University of Vi\u00e7osa, Vi\u00e7osa 36570-900, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3419-6075","authenticated-orcid":false,"given":"Jorge","family":"Gominho","sequence":"additional","affiliation":[{"name":"Center for Forestry Studies, Instituto Superior de Agronomia, University of Lisbon, Tapada da Ajuda, 1349-017 Lisbon, Portugal"}]},{"given":"Solange","family":"de Oliveira Ara\u00fajo","sequence":"additional","affiliation":[{"name":"Center for Forestry Studies, Instituto Superior de Agronomia, University of Lisbon, Tapada da Ajuda, 1349-017 Lisbon, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2020,11,28]]},"reference":[{"key":"ref_1","unstructured":"International Energy Agency (2018).
