Summary: The current energy crisis and waste management problems have led to the investigation of alternative solutions. This study explored the feasibility of pyrolysis of commonly used plastics as a way to recover energy and manage plastic waste. Results showed that pyrolysis of polyethylene terephthalate (PET), high- and low-density polyethylene (HDPE, LDPE), polypropylene (PP), and polystyrene (PS) resulted in flammable liquid products with high fuel conversion yields. The calorific values of these products were comparable to diesel and gasoline, making them potential fuel alternatives. Implementing this study could mitigate energy and environmental issues in developing countries and create entrepreneurship opportunities.

Summary: Seaweeds, primitive plants and macroalgae, typically grow in shallow water areas such as backwaters, estuaries, and seas. They attach to coral reefs, rocks, and other substrata. Researchers collected seaweeds from the Kanyakumari region and processed them to extract methanol using the Saccharification method. The highest yield of methanol (51.2%) was obtained with a substrate concentration of 15% and a time duration of approximately 48 hours. The study focused on producing methanol from a high concentration and choice of seaweed (Sargassum wightii).

Bio-control agents, such as Bacillus species, are seen as sustainable and safe alternatives. In our study, we focused on the application of Bacillus subtilis as a potential bio-control agent against the rice leaffolder pest, Cnaphalocrocis medinalis. The results showed that larvae fed with B. subtilis-amended diet had significantly reduced growth efficiency, highlighting the importance of B. subtilis in managing leaffolder disease.

Summary: A study screened a marine-derived red alga and its active constituents for their biocontrol potential against major insect pests. The larvicidal activity of the red alga extract was tested against Aedes aegypti, and its enzyme inhibition, repellent activity, and non-target toxicity were also evaluated. The results showed that the extract had dose-dependent toxicity against the exposed larvae of Aedes aegypti, and it exhibited repellent activity for a duration of up to 210 minutes. The extract also showed minimal toxicity to non-target species at the tested dosage. Overall, this study provides valuable insights for the development of bioactive insecticides and highlights the potential of algal-based pesticides for eco-friendly pest control.
