Ecosystem Services Provided by Seaweeds
This review summarizes the many ecosystem services that seaweeds provide, including food production, carbon storage, water filtration, and habitat for marine life. Seaweeds can also help combat pollution by absorbing heavy metals and other contaminants from the water. The review is relevant to microplastics research because healthy seaweed ecosystems may play a role in filtering microplastics from ocean water, and damage to these ecosystems could worsen marine plastic pollution.
Harnessing green tide Ulva biomass for carbon dioxide sequestration
Researchers reviewed the potential of using Ulva seaweed from harmful green tide blooms as a resource for carbon dioxide sequestration through biochar production. They estimated that Ulva biomass could capture approximately 3.85 million tons of CO2 equivalent, with nearly half stabilized through conversion to biochar. While not directly about microplastics, the study explores how repurposing marine biomass could address both coastal pollution and climate change.
Food packaging based on biodegradable polymers from seaweeds: a systematic review
This systematic review examines the use of seaweed-based biodegradable polymers as alternatives to conventional plastic food packaging. The research explores how seaweed materials can provide effective food packaging while breaking down naturally in the environment. Replacing petroleum-based plastics with biodegradable alternatives is one strategy for reducing the microplastic pollution that enters our food and water.
Emerging technologies for conversion of sustainable macroalgal carrageenan biomass into L-lactic acid: A state-of-the-art review
This review examines how macroalgae (seaweed) can be converted into lactic acid for making polylactic acid (PLA), a biodegradable plastic alternative. Using non-food biomass like seaweed to produce biodegradable plastics could help reduce dependence on fossil-based plastics that generate persistent microplastic pollution.
An Overview of the Alternative Use of Seaweeds to Produce Safe and Sustainable Bio-Packaging
This review explores how compounds derived from seaweed, particularly polysaccharides like alginates and carrageenans, can be used to create biodegradable packaging as an alternative to conventional plastics. Researchers found that seaweed-based biopolymers offer both functional packaging properties and potential health benefits, while avoiding the microplastic pollution caused by petroleum-based plastics. The approach represents a promising step toward reducing ocean plastic contamination by replacing single-use plastics with marine-sourced biodegradable materials.
Role of microalgae as a sustainable alternative of biopolymers and its application in industries
