The point of view of the respondents was examined using factor analysis, a Microsoft Excel (2016) add-on program (Liu et al., 2003; Wang and Xiao, 2004). Factor analysis is a technique that assesses if various variables, such as waste management economic significance, attitude toward waste, policy enforcement, and energy value, are linearly related. Each variable is regressed against the factors to test their loadings (Liu et al., 2003). Following the methodology outlined by Liu et al. (2003), factors were identified using principal component analysis (PCA), and data adequacy was evaluated using the Kaiser-Meyer-Olkin (KMO) normalization test. An unrotated factor matrix typically suggests the need for additional iterations, potentially under the theory that the best result is more likely achieved through further iterations under the same conditions. Mixed waste is sometimes collected at individual levels using unclassified containers before being hauled away by waste managers. Issues like poor protective covering of the buckets o1 breakdowns during collection contribute to problems with trucking- related littering. Plastics, batteries, cans, and glass bottles are ofter salvaged for recycling at dumpsites, while other waste is frequently burned directly, further harming the environment and _ posing significant health risks (Albanna, 2012; Ferronato and Torretta., 2019). Data matrices consisting of 61 columns by 46 rows of dependent and independent variables were created from the responses, as shown in Equation 3.

the pyrolysis of cellulosic materials include carbon dioxide (COz), carbon monoxide (CO), ammonia (NHs), methane (CHa), hydrogen (Hz), hydrogen cyanide (HCN), and water vapor (H2O). Additionally, the hydrocarbon fraction may contain methane, polycyclic aromatic hydrocarbons (PAHs), and a tar mixture composed of oxygenated species such as phenols, acids, light aromatics, and heavy tars (C1-C36 components) like pyrene and anthracene (Ayomoh et al., 2008). During cellulose degradation, the process may involve cleavage of the glucosidic bond or dehydration, typically occurring below 300°C. This results in gradual charring and depolymerization of the macromolecules. Higher temperatures lead to rapid glucosidic bond cleavage and evaporation of products. Cellulosic pyrolysis follows two pathways: one involves depolymerization forming levoglucosan, which further decomposes into flammable volatiles, and the other leads to complete dehydration to produce water and char.
