“…Subsequently, they were placed in a container with distilled water maintained at 23 • C for 24 h. Afterwards, the water on the surface of the specimens was quickly removed with a dry cloth, and they were immediately reweighed (W t ). The water absorption capacity (WA) was calculated as a percentage using Equation (2).…”

“…However, the most popular method is burning, as it is the easiest, fastest, and has a relatively lower cost. The ensuing impacts include the degradation of cultivated land, and the destruction of organic matter and soil nutrients, leading to the generation of smoke, ash, and micro-dust, and, most significantly, contributing to climate change [1,2]. This issue is a very important problem that should be resolved not only in Thailand, but throughout the world.…”

Plastic containers, commonly produced from non-biodegradable petroleum-based plastics such as polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET), raise significant environmental concerns due to their persistence. The disposal of agricultural waste, specifically rice straw (RS), through burning, further compounds these environmental issues. In response, this study explores the integration of polylactic acid (PLA), a biodegradable material, with RS using a twin-screw extruder and injection process, resulting in the creation of a biodegradable packaging material. The inclusion of RS led to a decrease in the melt flow rate, thermal stability, and tensile strength, while concurrently enhancing the hydrophilic properties of the composite polymers. Additionally, the incorporation of maleic anhydride (MA) contributed to a reduction in the water absorption rate. The optimized formulation underwent migration testing and met the standards for food packaging products. Furthermore, no MA migration was detected from the composite. This approach not only provides a practical solution for the disposal of RS, but also serves as an environmentally-friendly alternative to conventional synthetic plastic waste.
