“…The ash content was found to be low at 5.957 wt% and 5.988 wt%, respectively. As previously presented, any biomass with an ash content less than 5-6% does not undergo knocking trends [7,13,14]. The temperature range of thermal degradation of untreated waste peel is wider than that for pretreated waste peel.…”

“…The method was that 1.00-2.00 mg of the UM-WP and UN-WP samples was placed separately inside a muffle furnace according to Fig. 1 a, b The UM-WP and UN-WP samples ASTM E775-78 standards using PerkinElmer 2400 Series II as described by [7]. The HHV was determined using the known elemental composition with Eq.…”

“…These analyses were carried out on UM-WP and UN-WP biomass samples with a TGA thermostep analyzer manufactured by ELTRA, Germany. mg and 10 mg portion of the samples were prepared and heated from ambient temperature to 1000 °C at 10 °C min −1 under N 2 as described by [7]. The weight loss, fixed carbon, ash content, moisture, and heating rate were monitored and recorded.…”

“…Matooke (Musa-AAA -EA) is a variety of banana indigenous to Uganda, and is the most common staple food crop for human consumption in that country. It comes from the family of bananas known as East African highland bananas [6,7]. The waste residue of Matooke is the peels, and a large amount of Matooke peel (MP) is generated every year; so, it is the most abundant agricultural biomass in East Africa, especially Uganda.…”

“…The objective of this study was to characterize the unique biomass from two varieties of Matooke peel, namely, UM-WP and UN-WP with TGA, SEM, and EDXS. According to the available literature, there is only one published article on characterization of pretreated Mbwazirume and Nakyinyika biowaste [7]. Therefore, there is a need for additional experiments on pyrolysis and the combustion behavior of untreated Mbwazirume and Nakyinyika biowaste, and for comparison of the samples.…”

Biomass has several benefits due to its novel behavior among energy sources. This study aims to characterize a unique form of biomass from two varieties of Matooke peel, namely, untreated Mbwazirume waste peel (UM-WP) and untreated Nakyinyika waste peel (UN-WP). The analysis of the characteristics of these biomasses was carried out using TGA, SEM, and EDXS. TG and DTG analysis showed an almost identical trend between UM-WP and UN-WP. The UM-WP exhibited a high VC 69.988 wt%, MC 13.125 wt%, O 48.02 wt%, and HHV 15.52 MJ-kg −1 with a low ash content 5.957 wt%, sulfur 0.64 wt%, and N 1.13 wt% compared to UN-WP. As compared to pretreated biomass, it was found that the smaller particle sizes had only minor intra-particle gradients and the bigger particle sizes had more of a linear pattern variation. The pyrolysis behavior obtained revealed three distinct regions at elevated temperatures related to the elimination of cellulose, hemicellulose, and lignin. During carbonization, high fluidity and bubbles were produced due to the release of a large amount of volatile matter and forms porous structure which flowed through the fluid mass and produced a non-homogeneous vacuolated structure. These might cause the oxygen to easily disperse inside the particles during combustion. In addition, white spots were observed which are elements from different categories. The findings of this study indicate that UM-WP biomass could be an ideal material source for the production of biofuel and photovoltaic.
