ABSTRACT
This research develops an environmental mask made from biodegradable polylactic acid (PLA) material, which incorporates dandelion and Asclepias seeds connected by beeswax adhesive to achieve better filtration outcomes and support ecological development. The filtration mechanisms of the hairy seeds combine mechanical and electrostatic properties, and the PLA material transforms into soil after disposal, which enables seed germination for environmental restoration. A smoke-induced particulate filtration analysis demonstrated that using multiple layers containing seed elements decreased PM2.5 and PM10 matter more than filterless conditions, according to statistical results (p < 0.05). The research demonstrates potential uses of seed-based filtration for masks, but more improvements are needed to establish cost-effective mass production and maintain airflow accessibility. The microscopic analysis proved seed attachment successful but revealed airflow impairment because of overabundant beeswax application. This study presents a sustainable solution to combat mask pollution, which improves public health and supports soil productivity by planting seeds and enhancing the growth and fertility of the soil.
