The manufacturing and consumption of plastic products have caused depletion of petroleum resources and increased environmental pollution. Biobased plastics, while introduced as an alternative, have negative impacts on the environment and livelihoods. Marine-derived bioplastics offer a promising and cost-effective solution, but further research is needed. This review summarizes the raw materials, extraction processes, and properties of marine-derived bioplastics to accelerate their production.
The manufacturing and consumption of plastic products have steadily increased over the past decades due to rising global demand, resulting not only in the depletion of petroleum resources but also increased environmental pollution due to the non-biodegradable nature of conventional plastics. Moreover, despite being introduced into the market as an alternative to conventional petroleum-based plastics, biobased plastics are mainly manufactured from agricultural crop-based sources, which has negative impacts on the environment and the livelihoods of people. Marine-derived bioplastics are becoming a promising and cost-effective solution to the rising demand for plastic products. The physico-chemical, biological, and degradation properties of marine-derived bioplastics have made them promising substances for many applications. However, more research is required for their large-scale implementation. Therefore, this review summarizes the raw materials of marine-derived bioplastics such as algae, animals, and microorganisms, as well as their extraction processes and properties. These insights could thus accelerate the production of marine-derived bioplastics as a novel alternative to prevailing bioplastics by taking advantage of marine biomass.
