PLA straws have significant advantages in raw material selection, which stems from their use of renewable, bio-based materials.

The main raw material of PLA straws is plant-derived biomass, and common ones include corn starch. Compared with the petroleum-based raw materials used in traditional plastic straws, the plant-based materials used in PLA straws are renewable. This option helps reduce dependence on finite fossil fuel resources, thereby reducing irreversible damage to the environment. The renewable nature of plant-derived materials also provides a more sustainable production basis for PLA straws, which is in line with the global trend of sustainable development.

Secondly, the biodegradability of plant-derived materials is an important advantage in the selection of raw materials for PLA straws. PLA is a bio-based plastic made from the polymerization of lactic acid monomer extracted from plant sources. Under certain environmental conditions, such as a composting environment, PLA straws can be decomposed by microorganisms into water and carbon dioxide, forming harmless substances without causing persistent pollution to the environment. This is in sharp contrast to the difficulty of degrading traditional plastic straws and helps reduce the negative impact of plastic waste on the ecosystem.

The raw material selection of PLA straws helps reduce the carbon footprint. Plants absorb a large amount of carbon dioxide through photosynthesis during their growth, and the raw materials for PLA straws usually come from plants, which means that the carbon emissions during its manufacturing process are relatively low. Compared with petroleum refining and processing, the use of plant-derived materials can reduce greenhouse gas emissions throughout the entire life cycle, providing certain mitigation measures for climate change issues.

The raw material selection of PLA straws also meets today's pursuit of sustainability and environmental protection. As the world pays increasing attention to environmental issues, consumers and companies have put forward higher requirements for the selection of raw materials for products. The use of plant-derived materials in PLA straws not only performs well in terms of environmental protection, but is also in line with market trends, making it more competitive in the commercial and consumer markets.
