Can cotton khadaks counter pollution in Sikkim?

Gangtok: Travel through Sikkim, and it is impossible to miss prayer flags. The state is dotted with prayer flags and khadaks (polyester scarf), and while they give a distinct identity to the region, it is also one of the largest pollutants in the trans-Himalayan region. Across the Himalayas, from Mount Everest to the lower regions, khadaks are a way of paying respect to ancestors, departed souls, and Lord Buddha and other mountain deities. 

While there have been several initiatives to clean the region around and below Mount Everest and other Himalayan regions, is there a permanent solution to reducing/eliminating polyester flags?

Sikkim entrepreneur and product designer Sonam Tashi Gyaltsen believes so.
