Summary: In this study, a new enzymatic extraction technique was developed for the production of pure and intact fucoidans from brown seaweeds. The fucoidans obtained by this method showed higher amounts of fucose and sulfate, the main components of fucoidans, compared to traditionally extracted fucoidans. The extracted fucoidans also had low contamination of cellulose, laminarin, and alginate. This new enzymatic extraction technique provides high purity fucoidans for further study of their structures and biological activities.

Summary: We propose a sustainable and safe battery chemistry that uses iron and manganese hosted in alginate bio-material, which is widely available and inexpensive. The electrodes were synthesized by encaging the metals in alginate hydrogel, and characterized using FTIR, XPS, and Mossbauer spectroscopy. The electrochemical performance of the electrodes was evaluated through cyclic voltammetry and discharge experiments, showing high cycling efficiency. This research demonstrates the potential of using iron and manganese alginate electrodes in aqueous battery chemistry.

Summary: As tea consumption continues to rise, so does the production of biomass waste during the harvesting process. Tea waste (TW), including stems, leaves, and buds, has proven beneficial in energy generation, wastewater treatment, and pharmaceuticals. Conversion procedures such as pyrolysis, anaerobic digestion, and gasification efficiently recover energy from low- and medium-calorific value fuels. TW-derived biochar and activated carbon are promising adsorbents, while TW also shows potential in synthesizing phytochemicals. This review provides an overview of the conversion procedures and applications of TW, offering a comprehensive assessment of its sustainable use as a renewable resource.
