“…In other words, as the HDPE content in the mineral paper composition increased, the color change (darkening) also increased due to weathering or biological degradation. Similar to Chu and Nel's research, 19 it can be concluded that UV radiation greatly affects the mineral papers' color.…”

“…Although mineral paper appears similar to traditional paper, it technically is not actual paper because it lacks cellulosic fibers 18 . Furthermore, calcium carbonate is the primary ingredient in mineral paper, rather than an additive used as filler for a synthetic polymer base or cellulose paper 19 . The increasing awareness of the properties and usefulness of mineral papers, which do not contain toxic additives, has led to their widespread use.…”

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

“…The paper being printable, recyclable and water proof is a plastic alternative with good credentials. Stone papers can be used to make certified food-grade packaging, greaseproof paper wraps, ziplock bags etc (Ezcurra et al, 2012;Chu et al, 2019;Indriati et al, 2020).…”

Overuse of plastic that live on in nature has created a global crisis on our ecosystem and environment. Small particles of plastic of diameter upto 5mm called microplastics are found everywhere clogging the arteries of our mother nature. Microplastics absorb organic contaminants and act as vectors of potentially hazardous chemicals in living system. To save the flora and fauna of the earth from hazards of microplastics, the potential sources of microplastics should be identified and use of plastics be controlled and if possible terminated, Plastic litters should be recycled and reprocessed. To decrease our dependency on plastics, alternatives should be found. Research on plastic recycling and finding plastic alternatives should be scaled up. Most importantly common people should be made aware of the hazards of use of plastic. Public opinion in favour of termination of plastic use would be the most powerful weapon in saving the earth from this crisis

Flexible screen-printed electrodes (HP) were fabricated on stone paper substrate and amperometrically modified with gold nanoparticles (HP-AuNPs). The modified electrode displayed improved electronic transport properties, reflected in a low charge-transfer resistance (1220 Ω) and high apparent heterogeneous electron transfer rate constant (1.94 × 10−3 cm/s). The voltammetric detection of dopamine (DA) was tested with HP and HP-AuNPs electrodes in standard laboratory solutions (pH 6 phosphate-buffered saline (PBS)) containing various concentrations of analyte (10−7–10−3 M). As expected, the modified electrode exhibits superior performances in terms of linear range (10−7–10−3 M) and limit of detection (3 × 10−8 M), in comparison with bare HP. The determination of DA was tested with HP-AuNPs in spiked artificial urine and in pharmaceutical drug solution (ZENTIVA) that contained dopamine hydrochloride (5 mg/mL). The results obtained indicated a very good DA determination in artificial urine without significant matrix effects. In the case of the pharmaceutical drug solution, the DA determination was affected by the interfering species present in the vial, such as sodium metabisulfite, maleic acid, sodium chloride, and propylene glycol.
