The sensitivity of biopolymers to heat and flames necessitates the improvement of flame reaction. Traditional flame retardants are toxic and non-biodegradable, thus environmentally-friendly alternatives are being sought. This review promotes the use of biodegradable and bio-based compounds as flame retardants, highlighting their effectiveness in preventing flame spread.
Due to thermal and flame/fire sensitivity of biopolymers especially in plant-based biopolymer fillers, it is extremely and necessary to improve the reaction to flame. The bio-polymers currently are used in many appli-cations and daily life products and due to the potential risks of its tendency to burn and widespread the flames. To overcome these risks, an introduction of flame retardant (FR) compounds, additives, or fillers based on organic and inorganic approaches such as nitrogen-based FRs, halogenated-based FRs, and nano fillers have becoming significant incorporated into biopolymers. Most traditional uses of FRs that involve halogenated and inorganic FRs are toxic and non-biodegradable during disposal. Thus, the need to look for more environmentally friendly FRs such as nanocellulose, lignin, and others have become crucial. Because of concern on environmental and human health issues the biopolymers becoming a popular subject nowadays among scientists and re-searchers. The aim of this review paper is to promote the use of biodegradable and bio-based compounds for flame retardants with reduction in carbon footprint and emission. Furthermore, the addition of bio-based FRs are significant in preventing and reducing the spread of flames compared with conventional FRs. A detailed dis-cussion on the flame retardants mechanism, characterization techniques, morphology correlation and various biopolymers with flame retardants are also discussed.
