The widespread presence of MPs in the environment has raised concerns and encouraged research. Multiple studies have identified MPs across various environmental compartments. There is an increasing global concern regarding the environmental impact and accumulation associated with MPs. Bioplastics are currently being advocated as an alternative to conventional plastics. However, investigations focused on solutions for MP contamination are limited. Effective management of MP contamination requires understanding the distinctions between sustainable and conventional solutions. Hence, it is necessary to understand the sustainable solutions to MP pollution in freshwater and terrestrial ecosystems. Moreover, assessing the capacity of bioplastics to mitigate MP pollution in natural ecosystems through a review of existing research and innovative approaches is crucial for developing nations. Hence, this chapter will identify the shortcomings of conventional plastics and their contribution to MP pollution and highlight the necessity for sustainable alternatives. Lastly, this chapter discusses bio-based materials, biodegradable polymers, and other sustainable alternatives to enhance the environmental friendliness of plastic manufacturing and usage. This will assist policymakers and decision-makers in implementing appropriate measures to ensure sustainable solutions for MP pollution.
