Approximately 8000 synthetic chemicals are used to turn raw materials into textiles
200000 tons of dyes are lost to effluents every year during textile finishing

Interpretation
Fast fashion is turning rivers into toxic runways: from Citarum to Dhaka, textile mills that generate a fifth of the world’s industrial water pollution pour thousands of synthetic chemicals and lost dyes into waterways, release banned or carcinogenic substances like azo amines, NPEs, potassium dichromate and dioxins, dump tens of thousands of cubic meters of toxic effluent daily, drive pH to extremes and dissolved oxygen to near zero, leach heavy metals such as lead, mercury and antimony, corrode infrastructure with sulfides, and do it largely without proper treatment while downstream communities and ecosystems pay the price.
Global Scale & Volume
The fashion industry is responsible for producing 20 percent of global wastewater
The textile industry uses approximately 93 billion cubic meters of water annually
Water consumption by the fashion industry is projected to increase by 50 percent by 2030
The amount of water used in fashion annually is enough to meet the consumption needs of five million people
Textile production uses approximately 4 percent of global freshwater withdrawal
By 2030 the global middle class will increase to 5.4 billion people significantly increasing demand for water-intensive clothing
China’s textile industry discharges about 2.5 billion tons of wastewater annually
The apparel industry's water consumption is expected to reach 118 billion cubic meters by 2030

Interpretation
Treating water like a disposable accessory, the fashion industry already produces 20 percent of the world’s wastewater and consumes roughly 93 billion cubic meters a year, a burden set to climb to about 118 billion by 2030 and possibly rise 50 percent, so that from one kilogram of cotton needing up to 20,000 liters to billions of tons of toxic discharge in China, clothes are being made at the expense of rivers, farms and drinking supplies and could push 40 percent of the global population into severe water stress.
Microplastics & Synthetics
35 percent of all primary microplastics released into the environment come from laundering synthetic textiles
Approximately 500000 tons of microfibers are released into the ocean every year from washing clothes
A single wash load of polyester clothes can release 700000 microplastic fibers
16 to 35 percent of global microplastics released to oceans are from synthetic textiles
Microfibers from synthetic clothing have been found in the stomachs of fish in the deepest parts of the ocean
Synthetic fibers like polyester are non-biodegradable and persist in water systems for centuries
Wastewater treatment plants typically capture only 65 to 90 percent of microfibers allowing billions to pass through
Microfibers absorb toxic chemicals in the water making them more lethal when ingested by aquatic life
22 million tons of microfibers will be added to the ocean between 2015 and 2050 at current rates
It is estimated that 1.4 million trillion microfibers are currently in the ocean
Acrylic fabrics release microfibers at a rate of 730000 per wash five times more than polyester-cotton blends

Interpretation
Fast fashion is literally laundering plastic into the planet: a single polyester wash can shed about 700,000 microfibers, billions slip through treatment plants into tap water, oceans and deep-sea sediments where these non-biodegradable fibers soak up toxins, harm plankton and marine life and even show up in fish and on shorelines, and with polyester production tripling since 2000 we are signing up for decades of escalating, invisible pollution.
