Abstract

The demand and desire for environmentally conscious alternatives to conventional plastics have intensified after the introduction of biopolymers in our daily lives due to the question mark on the sustainability of the environment. The review is structured around key themes including classification and types of biopolymers, their recycling methodologies, disposal scenarios of biopolymers and their upcycling, life cycle assessment of some common biopolymers, biodegradability and biodegradation of biopolymers, the environmental impact of biopolymers and the influence of government policies in fostering biopolymer adoption. The review points out positive as well as negative factors associated with biopolymers along with greenhouse gas emissions/global warming potential and energy demand associated with bioplastics through life cycle assessments. This review aims for an easier understanding regarding the adoption of biopolymers into daily life considering all positive and negative aspects. The oceanic disposal and increasing land usage put the sustainability of biopolymers into jeopardy. This review aims to provide some clarity regarding the current situation and past actions taken by the world to promote sustainable development and the promotion of biopolymers. Despite all the positives and negatives, biopolymers have shown promise for a sustainable future by aiming to reduce the reliance on conventional fossil fuel-based polymers and non-biodegradable alternatives.

生物聚合物：可持续性、环境影响和生命周期分析的综合综述

由于对环境可持续性的质疑，在我们日常生活中引入生物聚合物后，对传统塑料的环保替代品的需求和愿望已经加强。这篇综述的主要主题包括生物聚合物的分类和类型、生物聚合物的回收方法、生物聚合物的处置方案及其升级回收、一些常见生物聚合物的生命周期评估、生物聚合物的生物可降解性和生物降解性、生物聚合物的环境影响以及政府政策对促进生物聚合物采用的影响。该综述通过生命周期评估指出了与生物聚合物相关的积极因素和消极因素，以及与生物塑料相关的温室气体排放/全球变暖潜力和能源需求。这篇综述的目的是为了更容易地理解生物聚合物在日常生活中的应用，考虑到所有积极和消极的方面。海洋处理和不断增加的土地使用使生物聚合物的可持续性处于危险之中。本文旨在对生物聚合物的现状和过去在促进可持续发展和促进生物聚合物方面所采取的行动提供一些清晰的认识。尽管有各种积极和消极的一面，但生物聚合物已经显示出可持续发展的前景，旨在减少对传统化石燃料聚合物和不可生物降解替代品的依赖。图形抽象
