Seaweed for climate mitigation, wastewater treatment, bioenergy, bioplastic, biochar, food, pharmaceuticals, and cosmetics: a review

Environmental Chemistry Letters, Год журнала: 2022, Номер 21(1), С. 97 - 152

Опубликована: Окт. 8, 2022

Abstract The development and recycling of biomass production can partly solve issues energy, climate change, population growth, food feed shortages, environmental pollution. For instance, the use seaweeds as feedstocks reduce our reliance on fossil fuel resources, ensure synthesis cost-effective eco-friendly products biofuels, develop sustainable biorefinery processes. Nonetheless, in several biorefineries is still infancy stage compared to terrestrial plants-based lignocellulosic biomass. Therefore, here we review seaweed with focus production, economical benefits, feedstock for anaerobic digestion, biochar, bioplastics, crop health, food, livestock feed, pharmaceuticals cosmetics. Globally, could sequester between 61 268 megatonnes carbon per year, an average 173 megatonnes. Nearly 90% sequestered by exporting deep water, while remaining 10% buried coastal sediments. 500 gigatonnes replace nearly 40% current soy protein production. Seaweeds contain valuable bioactive molecules that be applied antimicrobial, antioxidant, antiviral, antifungal, anticancer, contraceptive, anti-inflammatory, anti-coagulants, other cosmetics skincare products.

In modern times, seaweeds have become widely involved in several biotechnological applications due to the variety of their constituent bioactive compounds. The consumption dates ancient times; however, only from last few decades research can we explain mechanisms action and potential seaweed-derived compounds, which has led involvement food, cosmetic, pharmaceutical, nutraceutical industries. Macroalgae-derived compounds are great importance as properties enable them be ideal candidates for production sustainable “green” packaging. Diverse studies demonstrate that seaweed polysaccharides (e.g., alginates carrageenans) not provide health benefits, but also contribute biopolymeric film biodegradable dispersion plastics microplastics oceans provoke serious environmental issues influence ecosystems aquatic organisms. Thus, use biopolymers is now crucial replace plasticizers with materials, thus preserve environment. present review aims an overview on bioplastics might food or pharmaceutical

From plastic waste pyrolysis to Fuel: Impact of process parameters and material selection on hydrogen production

Fuel, Год журнала: 2023, Номер 344, С. 128107 - 128107

Опубликована: Март 24, 2023

Hydrogen is an energy carrier that can be utilized in various applications, including power plants, the synthesis of high-value products, and clean transportation fuels without emissions. Hence, hydrogen a potential candidate replace fossil reduce environmental pollution. The high demand for plastics driving production rate to increase yearly, leading great accumulation plastic waste materials resulting severe burden on environment. Thermo-catalytic conversion other promising route efficiently provide ideal long-term solution necessary overcome this challenge. Developing durable high-efficiency catalysts immerge from wastes industrial scale still challenge researchers. This study comprehensively summarizes discusses recently published literature using different thermo-catalytic processes, pyrolysis, pyrolysis-air gasification, pyrolysis-steam reforming, pyrolysis- (CO2) dry pyrolysis-plasma catalysis. scope review focus influence supports, method yield hydrogen, impact several crucial reaction parameters like pyrolysis temperature, catalytic catalyst plastic, steam ratios inclusive as well. conclusions will extremely valuable researchers interested sustainable generation H2 materials.
