Best practices for dye industry to reduce H-acid impact on marine
You must know that the textile dyeing and finishing industry has turned out to be the most chemically intensive industry all over the world. The same industry H-acid and other chemicals are used by H-Acid Manufacturers and has become top polluter of clean water after agriculture. While most chemicals used by the industry are hazardous and cause serious damage to human health in both direct and indirect ways. The mills are discharging millions of gallons of toxic waste that includes sulphur, naphthol, nitrates, soaps, acetic acid, heavy metals like copper, lead, mercury, cobalt, etc. But the sad thing about this is nothing can be done by the industry people to stop this effluent waste production except a solid best practice plan. In this post, we bring some best practice tips that industry people can follow to lower the damage caused by the released effluent into marine. RR trick RR refers to Reducing and Recycling. It is necessary for the professionals working in dye industry to remove several pollutants from waste waters prior disposal. By reducing all types of waste water, industry can save and enhance profits. Go Green approach We must change the ways of making and finishing the fabric. We must find the possibilities to create luxurious, sensuous fabric with non-toxic, sustainable, and ethical way. Mainstream manufacturers should be given access to environmentally appealing technologies. There are companies that have stopped using dyes on certain fabrics; however, it is still difficult to stop production of other colored garments due to consumer demand. Air dyeing technology
This technology includes a dye process that applies air to dye garments. Air dyeing technology allows companies to produce garments with vibrant designs and colors, without causing harm to environment. Bleaching Chlorine bleach is intensive toxic product yet it is used by chemical industry to manufacture fabric bleach. Companies can skip using this type of bleach and try oxygen based bleaching method that involves hydrogen peroxide. There are some factories that have started using ozone technology for bleaching. In this method, bleaching is done in cool water instead of hot water and release oxygen in waste water. Sizing Rather than using polyvinyl alcohol (PVA) for sizing, mills should start using potato starch or carboxy methyl cellulose (CMC). In this way, factories can make an organic approach for sizing. H-acid used by dye industry is not the only chemical that should be checked and used in limited amount. The final effluent has more toxic and hazardous chemicals that raise the temperature of waste water and make it extremely acidic. With these best practices, dye industries can contribute to environment and reduce marine pollution.
