    Innovative Bioplastics: Harnessing Microalgae and Low-Density Polyethylene for Sustainable Production

    Sayeda M. Abdo1,*, Mehrez E. El-Naggar2, Islam El Nagar3, Samar A. El-Mekkawi4, Youssef A. M.3,5

    Journal of Renewable Materials, Vol.13, No.3, pp. 599-616, 2025, DOI:10.32604/jrm.2024.057736 - 20 March 2025

    Abstract The accumulation of non-biodegradable plastic debris in the environment raises serious concerns about potential long-term effects on the environment, the economy, and waste management. To assess the feasibility of substituting commercial plastics for a biodegradable renewable polymer for many applications, low-density polyethylene (LDPE) was mixed with varying concentrations of algal biomass (AB). Algae are considered a clean, renewable energy source because they don’t harm the environment and can be used to create bioplastics. Algal biomass grown in a high rate algal pond (HRAP) used for wastewater treatment used at 12.5–50 weight percent. Mechanical, thermal,… More > Graphic Abstract

    Analysis of Highway Asphalt Modified with Recycled Rubber and Waste Plastics

    Aimin Zhang, Mingzhi Lu*

    FDMP-Fluid Dynamics & Materials Processing, Vol.18, No.4, pp. 907-918, 2022, DOI:10.32604/fdmp.2022.018995 - 06 April 2022

    Abstract In this study, it is shown how recycled rubber and waste plastics can modify the softening point and penetration of asphalt traditionally used for highways. It is shown that the modified asphalt can meet the performance index requirements when the components are present with a certain proportion or relative ratio (1:3.5). The dispersion process of the masterbatch in base asphalt can effectively be implemented, with good results and a smaller mixing time. The proposed approach may be regarded as a good strategy to achieve energy savings and protection of the environment. More >
