This century has witnessed an increase in the production and utilization of biocomposites and bionanocomposites. Various methods of preparation and characterization of polypropylene/starch-based biocomposites and bionano composites are discussed in this chapter. Application of PP/starch- based biocomposites and bionanocomposites in biomedical, packaging, automo- tive, military, coating, fire retardant, aerospace, and optical sectors are also covered. The recycling and lifetime studies conducted on PP/starch-based biocomposites and bionanocomposites are equally highlighted. © 2018 by World Scientific Publishing Europe Ltd.
