生物质能是一种很有前途的可再生能源，可替代化石燃料。生物质能不可避免地对地球生命造成环境影响，温室气体排放和环境污染以及随之而来的生态系统失衡是人们关注的主要问题。生物燃料和生物塑料是众所周知的从生物质中获得可再生产品的例子，它们已显示出取代传统燃料和塑料的越来越大的潜力。然而，生物燃料，特别是生物塑料面临的主要障碍是其缺乏竞争力的成本。此外，“插入式”塑料是市场的领导者，它减少了碳足迹，但继续说明大多数塑料产品的可生物降解性问题，包装部门。本章概述了生物燃料和生物塑料的共同特征和原料，旨在支持其相关的生产设置，以生物基和可生物降解的聚乳酸（PLA）和聚羟基烷酸酯（pha）为有前途的模型，预测未来几年快速增长的生产能力和生物降解的解决方案，用于短期和一次性塑料材料。
The biomass energy source has been a promising renewable alternative for fossil fuels and their inevitable environmental impacts on Earth’s life, from which the greenhouse gas (GHG) emissions and the environment pollution followed by consequent ecosys- tem imbalance are major concerns. Biofuels and bioplastics are well-known examples of renewable products obtained from biomass that has shown increasing potential to succeed the conventional fuels and plastics. However, biofuels and especially bioplastics have faced their main hindrance in their uncompetitive costs. Furthermore, the “drop-in” plastics are the market leaders, which reduce the carbon footprint but continue to state the biodegradability concern attributed to most of plastic products, the packaging sector. This chapter outlines the common features and feedstocks of biofuels and bioplastics aiming to support their associated production set toward the bio-based and biodegrad- able poly(lactic acid) (PLA) and polyhydroxyalkanoates (PHAs) as promising models with fast-growing production capacity forecasted for the next years and biodegradable solution for short-lived and disposable plastic materials.
