Quality of Pellet Made from Agricultural and Forestry Waste in Mexico

Hydrogen-rich syngas production from wood waste and wood waste pellet via gasification in updraft circulating fixed bed reactor

“…Similar biomass studies have shown that the thermochemical conversion of wood waste by pelletization is a beneficial pre-treatment to overcome these disadvantages [13][14][15]. Furthermore, pelletization improves fuel properties, such as energy homogenization, strengthening of fuel particles, homogeneity of form, and high energy and heat density [16], [17], [18], [19].…”

Environmental Impact Assessment of Heat Generation from Residues: a Forest-Based Industry Case Study

“…The study focuses on a sawmill located in Santiago Papasquiaro at the State of Durango, Mexico, which is the main timber forest national producer supplying 35.1% of wood, where 1591,141 round m 3 are destined for sawing, 394,737 round m 3 for pulp, 286,042 round m 3 for sheet and plywood, 13,763 round m 3 for posts, and finally 71,239 round m 3 for fuels with a total of 2,356,922 round m 3 with a monetary value of US$ 130,473,626 [7]. The unit round m 3 is used in sawmills and represents the volume of roundwood or sawn wood (logs from debarked trees) in m 3 .…”

“…Although the availability and utilization potential of forest biomass depend on the annual increment in forest volume and the annual demand of stem wood for building and other applied industrial purposes, this study analyzes the combustion of biomass as a source of energy in comparison with fuel oil in a sawmill. A recent paper [7] discussed the quality of pellet made from forestry waste in Mexico, while LCA of Mexican forest pellets for residential heating was described [8]. However, there are only few LCA on using forestry waste for bioenergy systems at industries [9][10][11][12].…”

“…Since it is estimated that Mexico has an energy potential of between 1135 and 1923 PJ/year from forest biomass, and 472 PJ/year from agricultural waste, with a worldwide contribution of 0.4% of the installed capacity to generate energy from biomass [8], the valorization of waste may be increased this energy potential by using forestry waste. Up to date 20% of timber production is used for trade and only 40% of waste is used [7]. Therefore, a case study is presented focused on the LCA of the generation of heat from forestry waste in a facility that produces timber and plywood in Mexico.…”

Fabrication of Iron-Containing Biochar by One-Step Ball Milling for Cr(VI) and Tetracycline Removal from Wastewater

“…Biochar (BC) was an ideal adsorbent with high efficiency and economy. , Due to its rich and developed spatial pore structure and functional groups, biochar can effectively remove Cr­(VI) pollution and TC pollution in water. , Furthermore, the raw materials for biochar production come from a wide range of cheap wastes. Among them, the waste sawdust produced by agricultural and forestry operations can be used as raw materials because of its low cost, plenty of production, and easy access. − However, if a quantity of sawdust was directly incinerated in the air rather than properly treated, massive gas pollutants (SO 2 , NO 2 , CO 2 ) and smog particles (PM 2.5) would be directly emitted into the atmosphere, causing great air pollution, it will cause great harm to human health and ecological environment. − Therefore, it was a win-win measure to protect the ecological environment by preparing sawdust into biochar for green secondary utilization . However, since the original biochar has few active sites, a method of modifying the original biochar was needed to improve the adsorption performance of the original biochar itself. − …”
