Industrial Scalable Additives for Enhanced Decomposition of Plastic Waste Through Photocatalysis

     JUNIPER PUBLISHERS-   ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract Polymer pollution is a dangerous environmental problem that can lead to the spread of toxic chemicals and microplastics throughout aquatic biomes. Commonly littered plastic from consumer goods and products with a limited or single use can be embedded with photocatalysts to avoid an increase in the amount of plastic present in Earth’s bodies of water. The photocatalyst nanoparticles, less than 100 nm particle size, were integrated into polyethylene terephthalate, high-density polyethylene, low-density polyethylene, and polystyrene and exposed under ultraviolet light over two independent experimental trials examining both the environmental factors impacting decay and the physical parameters required to implement this solution on a large scale. The plastics were chosen due to their prolific use in items such as grocery bags, bottles, and packaging. The first half of the project examined the effects ...

Production of NSSC Cellulosic Pulp Fibers from Eucalyptus Cameldulensis-Juniper Publishers

Image
    JUNIPER PUBLISHERS-   ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract This study has aimed to investigate production of neutral sulfite semi-chemical (NSSC) pulping from eucalyptus camaldulensis in Zabol, Sistan & Balouchestan, Iran. Chemical composition including cellulose, lignin, extractive and ash were measured (48.33%), (28.49%), (5.94%) & (0.65%) respectively, while dimension of fibers including length (0.935mm), diameter (19.13μm), lumen cavity (8.89μm) & cell wall thickness (5.12μm). Cooking conditions were consist of three levels of chemical charge (10, 14 & 18% on O.D weight), constant time of 90min, constant temperature of 170 °C & liquor to wood ratio of 7:1. The pulps were refined to 400±25mL, CSF & 127gm-2 hand sheets were made. Finally, strength properties of the pulps were compared and evaluated with that of Mazandaran Wood and Paper Industries (MWPI), Iran. The results showed that pulp yield decreases with increase of chemica...
