  Abstract The demand for Critical Minerals (CMs) is soaring because of their extensive use in renewable energy generation, energy storage, energy transmission, scientific instrumentation, and a wide range of communication, military, and transport technologies. However, the supply of CMs faces several critical challenges like • a few countries have a monopoly in mining and processing of particular CMs • variable concentration and deposit grades in different geographical areas • inadequate assessment of resources • inefficient mining, extraction, and processing technologies, • little to no recycling • limited workforce and • severe environmental and human health impacts associated with CM mining, processing, and production. For environmentally sustainable development of the CM industry, countries need to make significant investments in advanced competitive research, development of efficient environment-friendly mining, extraction, and processing te...

Juniper Publishers-Open Access Journal of Environmental Sciences & Natural Resources Natural Dyeing of Cotton Fabric by Extruded Pelargonidin of Red Onion Skin and Finished it Naturally with Aloe Vera Authored by Ashish Debnath Abstract According to the opinion of the Ecologist, the Textile industry is regarded as the most polluting sectors. Almost every single day, various textile industries mostly Dyeing factories are ejaculating different toxic chemicals, dyes and other agents which are very much harmful to our nature and environment. As a result, the demand for natural dyes has increased abundantly. Natural dyes are environment friendly. In this project, we used onion outer skins as a potential source of natural plant dyes. These dyes, which are known as pelargonidin were applied on cotton fabric by the exhaust method. For proper fixation, drying and curing is carried out in Mini Thermosol Machine. The dyed sample was evaluated for color fastness to washing, light, rubbing and...
