Applying the Multifaceted Potential of Seaweed in Bioplastics to Advance Sustainable Development in Sri Lanka – A Review
AI summary Read the abstract
Researchers review the potential of seaweed-derived bioplastics as a sustainable alternative to petroleum-based plastics, arguing that Sri Lanka's established seaweed aquaculture, marine biodiversity, and proximity to Asian markets position it to become a competitive regional bioplastics producer as global demand grows.
Plastic pollution remains a critical environmental and public health challenge. Bioplastics have emerged as a promising alternative to reduce the adverse impacts of petroleum-based plastics. Among renewable biomass sources, macroalgae, particularly seaweeds, stand out due to their high biomass yields, cost-effectiveness, and ease of cultivation. For an island nation like Sri Lanka, seaweed-based bioplastics present a unique opportunity to advance sustainability while strengthening the economy. Sri Lanka already has an established seaweed farming industry, primarily exporting dried seaweeds, which could be expanded into value-added bioplastic production. Several studies project a significant global increase in bioplastic demand by 2028, underscoring the potential market. With its year-round cultivation potential, rich marine biodiversity, and proximity to major Asian markets, Sri Lanka is well-positioned to become a competitive player in the regional bioplastics industry. This review examines bioplastic production from seaweeds, with a focus on its applicability, benefits, and strategic relevance for Sri Lanka as a developing country.

A comprehensive review of renewable bioplastics with a focus on Algae-derived alternatives for sustainable development
AI summary Read the abstract
Researchers evaluated algae-derived bioplastics as sustainable alternatives to petroleum-based polymers, showing 40-60% reductions in CO2 emissions and a potential to reduce marine microplastic pollution by 20-30% by 2030. Shifting to biodegradable bioplastics is a critical upstream intervention because conventional plastics persist in the environment for centuries, continuously fragmenting into the microplastics that accumulate in human tissues.
