Textile Mills: Pollution And Environmental Impact

The apparel industry is one of the biggest polluters on the planet. Textile mills generate one-fifth of the world's industrial water pollution and use 20,000 chemicals, many of which are carcinogenic. Textile manufacturing operations create large amounts of toxic and nontoxic solid waste and release harmful pollutants into the atmosphere, including nitrous oxides, sulphur dioxide, carbon monoxide, chlorine dioxide, hydrocarbons, ammonia and formaldehyde.

Textile mills generate one-fifth of the world's industrial water pollution

The apparel industry is one of the biggest polluters on the planet, and textile mills are a significant contributor to this problem. Textile mills generate one-fifth of the world's industrial water pollution, and the issue is particularly acute in developing countries, where governments struggle to keep up with the industry's massive pollution footprint.

Textile manufacturing operations create large amounts of toxic and non-toxic solid waste. Common toxic-solid waste pollutants include storage drums and plastic containers used to hold hazardous chemicals and solvents. Leftover powdered dyes and dye containers, scrap metal, oily cloths, and wastewater sludge can also contaminate the soil and groundwater sources if not properly disposed of or released untreated. In addition to solid waste, textile mills release a variety of toxic chemicals and pollutants into the water and air.

The dyeing and finishing processes in textile manufacturing are especially harmful to the environment. Textile dyeing is the second-largest polluter of water worldwide, and the fashion industry produces 20% of the world's wastewater. Mills use a range of chemicals in these processes, including polyvinyl chloride for sizing fabrics, chlorine bleach for lightening, benzidine and toluidine as dyeing agents, and flame retardants, many of which are known carcinogens. These chemicals are released into waterways and groundwater sources, polluting them and causing detrimental effects on the environment and all types of life forms.

To address this issue, initiatives such as the NRDC's Clean By Design program work with major apparel retailers and brands to reduce pollution and cut water, chemical, and energy use in their supply chains. The program has been introduced to nearly 200 textile mills, and participating mills have reduced water use by up to 36%, cut energy use by up to 22%, and decreased their chemical usage. Additionally, the US EPA has promulgated the Textile Mills Effluent Guidelines, which include national emission standards and regulations for the treatment and disposal of wastewater and solid waste from textile mills.

Textile mills use carcinogenic chemicals

The textile industry is one of the leading industries in the world, employing thousands of workers. Unfortunately, it is also one of the biggest polluters, with textile mills generating a significant portion of the world's industrial water pollution. The industry's massive pollution footprint is a challenge for governments, especially in developing countries where most of the world's textile factories are located.

Textile mills use a variety of chemicals in their processes, many of which are carcinogenic. These include dyes, solvents, optical brighteners, finishing agents, and natural and synthetic fibre dusts. The use of these chemicals has been associated with serious health hazards, including cancer. Studies have reported genotoxicity and cancer deaths among textile industry workers, indicating that those employed in this sector are at a higher risk of developing cancer.

Dyes, in particular, are known to possess carcinogenic properties. Azo dyes, which are the most commonly used type, are aromatic hydrocarbon derivatives of benzene, toluene, naphthalene, phenol, and aniline. These chemicals have been linked to an increased risk of various cancers, including lung, bladder, colorectal, and breast cancer. Additionally, the solvents used in the industry have been found to contribute to the carcinogenic effects by direct contact with workers.

Other toxic chemicals used in textile mills include formaldehyde, lead, mercury, benzidine, toluidine, and flame retardants. These chemicals are released into the air and water during the manufacturing process, leading to air and water pollution. For example, fabric-finishing operations can release formaldehyde, a known toxin, into the air. Untreated chemical wastewater can contaminate waterways and groundwater sources, further exacerbating the environmental and health impacts of the industry.

The problem of carcinogenic chemicals in the textile industry is not limited to the mills themselves but also extends to the wider ecosystem and human health. Untreated textile mill effluents containing complex chemicals, metal contaminations, and other organic agents can accumulate in natural sources such as soil and water, leading to hazardous consequences.

Textile mills contribute to air pollution

The apparel industry is one of the biggest polluters on the planet. Textile mills contribute significantly to air pollution, releasing various toxic chemicals and pollutants into the atmosphere. The burning of coal for energy by textile factories, particularly in China, produces about three billion tons of soot annually, causing air pollution linked to respiratory and heart disease.

Textile manufacturing operations generate a range of toxic chemicals and solid waste. During the production process, untreated life-threatening pollutants are released into the air, endangering human health and the environment. Factory boilers emit nitrous oxides and sulphur dioxides, while sizing operations release carbon monoxide. Bleaching operations release chlorine dioxide, and fabric printing releases hydrocarbons and ammonia. The use of organic raw materials, such as organic cotton, can help reduce emissions, as can implementing environment-friendly manufacturing methods.

Fabric-finishing operations can release formaldehyde, a known carcinogen, into the air. Other toxic chemicals used in textile production include polyvinyl chloride for sizing fabrics, benzidine and toluidine as dyeing agents, and flame retardants. Leftover powdered dyes, dye containers, scrap metal, oily cloths, and wastewater sludge can contaminate soil and groundwater sources if not properly disposed of.

Textile mills also contribute to air pollution through the release of per- and polyfluoroalkyl substances (PFAS). PFAS are synthetic chemicals used in various industrial processes, including textile manufacturing. According to the Environmental Working Group (EWG), at least 1,501 textile manufacturers in the United States may be discharging PFAS. PFAS exposure, even at very low levels, can have serious health impacts, and the lack of stringent regulations on PFAS discharges into the air and water by textile mills is concerning.

Furthermore, the textile industry's high water consumption and use of hazardous pesticides and fertilizers contribute to land pollution, as the majority of these chemicals fall onto the land during application. Surveys indicate that textile waste consumes nearly 5% of landfill space, and textile treatment and dyeing account for 20% of freshwater pollution. The global textile industry's pollutants cause long-term damage, rendering land useless and barren.

Textile mills produce toxic solid waste

Textile mills contribute to one-fifth of global industrial water pollution and use 20,000 chemicals, many of which are carcinogenic. They produce toxic solid waste in the form of fibres, hemp, yarn, and fabrics, which are created directly from production lines. The cones, looms, and cardboard reels used to hold fibres and textiles during manufacturing also add to a factory's solid waste pollution.

Textile mills generate wastewater during processes such as wool scouring, topmaking, and the general cleaning of raw wool. Wool finishing, including carbonizing, fulling, dyeing, bleaching, rinsing, and fireproofing, also creates wastewater. The wastewater is contaminated and harmful, and when released into bodies of water without proper treatment, it disrupts aquatic life and the millions of humans who rely on that water.

The dyes used in the textile industry are largely toxic, and their degradation products, such as aromatic amines, may be allergic in nature. Untreated textile mill effluents are a major concern as they are associated with hazardous problems for ecosystems and human health. Complex effluents, including a number of dyes, metal contaminations, and other organic agents used for softening, printing, and heat stabilizing, can accumulate in natural sources like soil and water if disposed of without treatment or after incomplete treatment.

Textile mills also produce toxic solid waste in the form of storage drums and plastic containers used to hold hazardous chemicals and solvents. Leftover powdered dyes and dye containers, scrap metal, oily cloths, and wastewater sludge can contaminate the soil and groundwater sources if not properly disposed of or released untreated.

Textile mills contaminate soil and groundwater

The US Environmental Protection Agency (EPA) has acknowledged the presence of Per- and polyfluoroalkyl substances (PFAS) in wastewater discharges from textile mills. PFAS are synthetic chemicals found in various consumer and industrial products. While the EPA is working to address this issue, most textile mills are not required to monitor for PFAS, potentially leading to ongoing discharges into the environment.

The textile industry is a significant contributor to water pollution, generating one-fifth of the world's industrial water pollution. It is also the largest producer of wastewater, discharging a substantial volume of contaminated effluent into natural sources. This wastewater contains complex mixtures of dyes, metals, and organic agents, which can accumulate in soil and water sources if not properly treated.

The solid waste generated during textile manufacturing, such as hazardous chemicals, solvents, dye containers, scrap metal, and oily cloths, further contributes to soil and groundwater contamination if not disposed of properly. Additionally, the boilers and sizing operations used in textile mills release nitrous oxides, sulphur dioxides, and carbon monoxide into the air, leading to air pollution and potential deposition of toxic substances onto soil and water bodies.

To address these environmental concerns, the EPA has implemented regulations and guidelines, such as the Textile Mills Effluent Guidelines, to govern textile mill operations and reduce their impact on soil and groundwater quality. These regulations include standards for wastewater treatment and the disposal of solid waste to minimize contamination.
