Abstract: Natural food waste is a significant contributor to environmental degradation, with landfills containing tonnes of this waste material, which leads to the release of harmful gases and contributes to the increase in global warming. However, natural food waste has several valuable industrial applications, and one such application is producing activated carbon, renowned for its superior adsorptive properties. Activated carbon made from natural food waste has been used for colour in natural dye treatment, mostly from textile industries. Colour fastness efficiency is critical, and in this aspect, activated carbon from natural food waste has shown significant improvements in natural colour fastness. Activated carbon can be produced from different biomass materials, which include coconut shells, sawdust, peat, rice husks, among others. However, natural food waste, including, banana peels, coconut shells, lemon woods, egg shells sea shells, and tea leaves, has been identified as a vital source for producing activated carbon. The application of natural food waste for activated carbon production has several advantages, including its abundance and an inexpensive method of acquisition. Additionally, the use of natural food waste for activated carbon production provides a sustainable approach to waste management, reducing the carbon footprint in the environment. This study demonstrated the This paper reports the studies available on the extraction of dyes from egg shells, finishing with two different natural fabrics bamboo and cotton fabric in different blending ratios and identifies the effects of different mordants and mordanting methods on the color shade. Egg shell-based activated carbon was successfully synthesized by the simple chemical activation process From an environmental point of view, replacing synthetic dyes with natural ones is not only a strategy to reduce risk and pollutants, but also an opportunity for new markets and jobs. this is necessitates newer research on application of natural dyes on different fabric for completely ecofriendly textiles .the fundamentals of naturals dyes chemistry and some of the important research work were therefore discussed in this article.

Keywords: Natural dyes, bamboo and cotton fabric, Egg shell, environment, colour fastness.
