The process by which silk thread is separated from the cocoon is called reeling the silk. The boiling of cocoon leads to formation of vapours that can pollute the environment and also cause respiratory problems. It is for this reason that sericulture is not considered as an eco-friendly practice.
therefore putting cocoons in hot water is not an eco-friendly activity.
