PLA is made from renewable resources like corn starch, cassava, and sugarcane
Polylactic acid or polylactide (PLA) is a thermoplastic made from renewable resources. These renewable resources include plant-based materials like corn starch, cassava, and sugarcane. PLA is a bioplastic made from renewable, plant-based materials. It is a polyester made from renewable biomass, typically from fermented plant starch.
The process of making PLA begins with the cultivation of crops, usually corn in most commercial PLA production. Corn starch or another starch-rich plant material like cassava or sugarcane is used as the primary resource. These crops are grown and harvested, offering a renewable and readily available feedstock. Unlike petroleum-based plastics, which require drilling and extraction, PLA relies on agriculture. This means its raw materials can be regrown season after season, making it a sustainable and renewable option.
The region in which PLA is produced influences the resources used. For example, sugarcane-based PLA is prominent in tropical regions like Brazil and Thailand, while corn dominates in North America. PLA is derived from renewable agricultural crops like corn, meaning it doesn't rely on fossil fuels. With the purchase of a PLA-based product, one supports greener, renewable sources.
PLA is a viable solution with improvements to the technology expected in the future. However, it is important to note that growing crops and using fertilizers can impact our land and waterways. Additionally, PLA plastic packaging can be more expensive than its conventional plastic counterparts due to the number of steps required in the production process.
