“…This correlates with its lower calcium carbonate content and higher HDPE level, which would hinder mineral dissolution during biodegradation. Comparing these trends with literature, similar reductions in roughness of HDPE/calcium carbonate composites after UV weathering were reported by Abd El‐Rahman et al 34 They attributed this to photo‐degradation of the plastic component. Additionally, Al‐Salem et al 35 observed decreased roughness of calcium carbonate papers after burying in compost, consistent with the biodegradation results here.…”

Mineral paper, a synthetic paper‐like material primarily composed of ground calcium carbonate (CaCO3) and a small amount of high‐density polyethylene (HDPE), has emerged as an important alternative to traditional paper and board due to the increasing demand for pulp and paper and the shortage of trees and fibrous material in many regions worldwide. This study aimed to investigate the impact of accelerated weathering and aerobic biodegradation on three different types of mineral papers. The specimens underwent 1000 h of accelerated weathering using a Gardner weathering device and were also buried in soil at a depth of 5 cm for 3 months with regular watering conditions for biodegradability testing. Physico‐chemical characterizations such as optical (whiteness), surface (roughness, contact angle, and paper topography), and chemical properties of the samples were studied before and after the artificial weathering and biodegradation tests. The results revealed a visible color change (darkening) in mineral papers, with an increase in HDPE content leading to a darker color after weathering and biological degradation. However, there were no significant differences in the color change between weathering and soil‐burial tests. The biodegradability test resulted in a decrease in ash content due to the demineralization process. All samples' surface roughness was reduced after weathering and biodegradation tests. The FT‐IR and EDS analyses confirmed the presence of calcium, carbon, and oxygen elements in all three samples, indicating a large amount of calcium carbonate in the mineral papers. The scanning electron microscopy (SEM) images showed the creation of micro holes and cracks on the surface of the samples after weathering and biodegradation. Overall, the soil‐burial test showed more degradation than the weathering test.Highlights The influence of weathering and biodegradation of mineral papers were studied After soil‐burial test, the ash content decreased due to the demineralization After weathering, micro cracks were created on the surface of the samples The degradation of the soil‐burial test was more than the weathering test Mineral papers most likely contain carbonate calcium and HDPE

“…Biodegradation, defined as the decomposition of materials mainly by fungi or bacteria, is a natural process that acts on substances such as leaves, grass, and food scraps. The technique of biodegradation has been extended to break down artificial products, mainly plastics such as aliphatic polyesters, aromatic co-polyesters, and polyethene [ 1 , 2 ]. Low-Density Polyethylene (LDPE) biodegradation has emerged as an active and attractive area of research in the past 20 years or so, due to the various problems associated with conventional chemical methods, such as the need for high temperature in pyrolysis, highly corrosivity of ozonolysis, and complex by-product treatments in chlorine attacking [ 3 ].…”

Low-Density polyethylene is subject to biodegradation using a fungal consortium comprising of Aspergillus niger , Aspergillus flavus and Aspergillus oryzae under laboratory conditions. The extent of biodegradation has been compared with the use of potato dextrose broth and czapek dox broth media and also in the presence and absence of Tween 80 additive. Biodegradation was performed replacing the sucrose in czapek dox broth with shredded Low-Density polyethylene as well. The biodegradation was carried out for a period of 55 days. The degree of biodegradation has been analyzed using the loss of weight, FT-IR, and SEM analysis. A maximum weight loss of 26.15% was obtained by using potato dextrose broth over a period of 55 days.
