“…In case of integrated approaches, the operational costs of biogas purification (Case4) and VFA recovery (Case5) costs are around 5 and 21% of total production costs respectively. Previously, [33] observed the same phenomenon that feedstock costs and operating labor are the influencing parameters in the manufacturing costs for the conventional torrefaction process.…”

“…Torrefied biomass has been explored as an option to complement or replace coal. ,, A recent techno-economic analysis suggested that torrefied biomass can be produced at a competitive market price compared to conventional raw biomass and can be comparable to coal if carbon credits are included in the analysis . While replacing coal with biomass, including torrefied biomass, has a climate benefit due to the reduction in greenhouse gas emissions, the impact on emissions of air pollutants, including aerosols (or particulate matter, PM), is less clear.…”

Torrefied biomass is a promising carbon-neutral alternative to coal. However, the effect of torrefaction on aerosol production in biomass combustion is understudied. Here, we compared the emissions and physicochemical properties of aerosols produced by the combustion of raw pine, torrefied pine, and bituminous coal. At the highest combustion temperature of 1000 °C, aerosol emission from coal was 5.2 ± 0.4 mg/MJ, while emissions from raw and torrefied pine were negligible (<10–2 mg/MJ). The coal–combustion aerosol was dominated by inorganics (85%), with a small organic fraction (15%), a composition typical of condensable particulate matter observed in power generation applications. At the lowest combustion temperature of 400 °C, aerosol emissions from raw pine (25.3 ± 4 mg/MJ) and torrefied pine (5.6 ± 0.8 mg/MJ) were dominated by organics. The organic molecules probed using electrospray ionization mass spectrometry were dominated by CHO and CHNO groups for both raw and torrefied pine. Torrefied pine emissions featured less aromatics (17% vs 22%), which can be attributed to the reduction in volatile matter content associated with torrefaction. Overall, our findings support the adoption of torrefied pine for domestic burning and power generation because of the added benefit of reducing aerosol emissions in addition to being carbon-neutral.

“…It has been predicted that the global energy demand will rise by 28% by 2040, leading to concerns about energy security, global climate change, and the need for sustainable, renewable energy sources (Owusu and Asumadu-Sarkodie 2016;EIA 2017;Manouchehrinejad et al 2021). As fossil fuels have been phased out, renewable energy sources such as wood pellets have grown in importance (Luo et al 2020).…”

Properties of unheated wood pellets were compared with those of torrefied wood pellets that had been heated to 270, 290, and 310 °C, with raw material taken from two different height levels of oil palm trunk (OPT). The gross calorific value, moisture content, ash content, volatile matter, fixed carbon, density, and weight loss were examined. Air drying or oven drying pretreatment was applied to the raw materials. The results showed that the heating values of samples increased when raw materials were torrefied, depending on the heat treatment temperature. The torrefied pellets were improved by as much as 66.4% in heating value compared with OPT pellet samples. The greatest improvement was found in torrefied pellet samples prepared at 310 °C, using air drying, and height levels of OPT between 0.3 to 1.5 m. The ash content of samples tended to increase when the torrefied temperature was increased, while the volatile matter value was reduced with high temperature. Based on the findings, OPT could be used as a raw material to produce value-added white and torrefied pellets as sustainable solid biofuel.
