The textile industry is actively investigating methods and technologies to enhance its environmental performance because of its substantial and well-known impact on greenhouse gas emissions worldwide. The internationally acknowledged Life Cycle Assessment (LCA) technique is a primary tool for calculating environmental consequences. Specifically for the computation of the impact of textile products in the apparel and footwear category, Product Environmental Footprint Category Rules (PEFCRs) are developed. A growing number of companies are joining the sustainable movement as customers become more conscious of the effects that the items they use have on the environment. These companies must examine their supply chains and product designs and search for ways to reduce pollution and carbon emissions to lower their effect. This paper has reviewed Case studies on the Life Cycle Assessment of T-shirts, the most commonly used garment.

Green Synthesis of Silver Nanoparticles Using Equisetum Plant Extract and Its Antimicrobial Activities and Dye Degradation Behaviour

Silver nanoparticles were prepared using the green synthesis method using Equisetum plant extracts. The plant extracts reduce silver ions into silver nanoparticles at ambient conditions. The process is straightforward, rapid, cost-effective and environment friendly. The silver nanoparticles were characterized by UV-visible spectroscopy, IR spectroscopy, SEM and XRD study. The average particle sizes are in the range of 10–20 nm. The UV–visible spectra of the silver nanoparticles exhibit an absorption band around 350 nm which suggests that the size of the silver nanoparticles is small. IR spectra show the characteristic peaks of flavonoids, terpenoids, and fatty acids of the plant extract. The antimicrobial activity of green synthesized silver nanoparticles was carried out using the disc diffusion method against human pathogens. Small-size silver nanoparticles show high antimicrobial activity in this work. The synthesized silver nanoparticles have also been chosen for the catalytic degradation of different dyes.
