To protect the environment, most countries around the world have introduced restrictions on the use of traditional plastics. In this context, biodegradable plastics have emerged as an ideal alternative. Among them is PBAT, which is technologically mature and cost-effective and therefore could capture a big market share. Since the central government issued the plastic limit order in 2020, PBAT demand has surged in China, which in turn has driven up the demand for BDO. in response, numerous new PBAT capacities have been built and put into operation. For example, recently Inner Mongolia Huanian New Energy Technology’s integrated PTMEG and PBAT project conducted trial run, laying a foundation for its start-up.

Thanks to its excellent breathability and biodegradability, PBAT has been widely used in agriculture, especially in the manufacture of biodegradable mulch films. The residues of traditional polyethylene films could pollute soils and groundwater. By contrast, it has been found that PBAT/PLA-based mulch films can significantly increase soil electrical conductivity and organic content to make soils more fertile and productive.

Owing to its good thermal stability, PBAT can also be used in disposable tableware. As it provides similar appearance and strength to traditional plastic tableware, the biodegradable plastic has become the most widely used composite for making disposable pulp molded tableware, which is used for outdoor activities, picnics, parties and other occasions to reduce environmental impact.

Besides, PBAT can also be used in plastic bags and packaging films. The degradability of PBAT depends on environmental conditions, such as temperature and humidity. In applications, its performance and degradation rate should also be considered in addition to these factors so as to ensure its suitability and environmental-friendliness.
