Summary overview

This document summarizes scientific concepts, discoveries, and field reporting about global textile production, waste, environmental impacts, microplastic pollution, local manifestations in Ghana, Bangladesh and Korea, methods used to study these issues, key quantitative findings, proposed solutions, and key people/organizations cited.

Global production and waste of clothing

Roughly 100 billion garments are produced worldwide each year.
About one third of produced garments (~33 billion) are discarded within the same year.
Approximately 12% of garments are discarded immediately after purchase (never used).
Many used-clothing collection systems export large volumes abroad; for example, Korea exports ~95% of collected used clothes and is reported as the world’s 5th largest exporter of used goods.

Environmental impacts of textile production and disposal

Textiles require very high water and energy inputs. Example figures:
- One cotton T‑shirt ≈ 2,700 liters of water.
- One pair of jeans ≈ 33 kg CO2 (roughly equivalent to 111 km of car travel).
The fashion industry emits roughly 10% of global greenhouse gases — more than shipping and aviation combined.
Overproduction and unsold inventory frequently lead to incineration or landfilling of new clothes, producing air pollution (black smoke) and long‑lasting waste.

Overproduction and disposal of new garments create both immediate pollution (incineration smoke) and persistent waste burdens.

Plastic‑based fibers and microplastic pollution

Synthetic fibers (especially polyester/PET) now constitute a large fraction of modern clothing; polyester represents more than 50% of global fiber production.
PET used for fibers is chemically the same polymer base as PET bottles and is derived from petroleum.
Synthetic textiles shed microplastic fibers during wear and washing; these fibers enter sewage systems, rivers and eventually oceans.
Field sampling (Han River) found synthetic fibers made up over ~50% of microplastics detected; concentrations correlated with population density and usage.
Laundry experiments reported very large releases of microplastic particles from clothing abrasion — on the order of hundreds of thousands of particles per kilogram of laundry (reported ~500,000–670,000 particles/kg).

Local manifestations of global textile waste

Ghana (Accra / Kantamanto market)
- Huge inflows of cheap used clothes overwhelm markets.
- Overflow results in nearby dumps and textile “graves” on beaches; clumps of cloth wash ashore and must be cleared by villagers.
- Livestock in affected areas ingest synthetic fibers.
Bangladesh (Dhaka)
- Massive garment production concentrated in low‑wage factories.
- Industrial wastewater and textile scraps heavily pollute local canals and rivers, killing aquatic life and creating “rivers of death.”
Korea (used‑clothing export/processing)
- Large volumes of collected used clothing are sorted and exported abroad; domestic systems heavily depend on international demand.

Methods and experiments described

River microplastic sampling (Han River)
1. Surface water sampled at three locations: upper Han (drinking source), mid reach near Paldang Dam, and lower Han (urban Seoul).
2. Water collected using a net and filtered through 20‑micrometer filters.
3. Microplastic particles identified and counted using microscopy and material analysis to classify types (e.g., synthetic fibers).
Laundry microplastic release test
1. Garments prepared from different materials (cotton, polyester, acrylic).
2. Washed at 40°C in a household washing machine.
3. Wastewater filtered through a filtration device to capture residues.
4. Residue analyzed and microplastic particles counted; results showed very high fiber counts released per kg washed (~5×10^5–6.7×10^5 particles/kg reported).
Field observation / reportage
- On‑site reporting in Ghana (market and coastal dumping), Dhaka (factory zones and polluted rivers), and Korean used‑clothing export/processing facilities documented garment flows, sorting practices, and local pollution.

Key quantitative findings

Annual garment production: ~100 billion pieces.
Annual garments discarded within a year: ~33% (~33 billion).
Polyester share of global fiber production: >50%.
Water to make one cotton T‑shirt: ~2,700 liters.
CO2 per pair of jeans: ~33 kg.
Microplastics released in washing: hundreds of thousands of particles per kg of clothing (reported ~500,000–670,000 particles/kg).
Korean used‑clothing export: ~95% of collected used clothes exported; Korea cited as the 5th largest exporter of used goods.

Solutions and alternatives presented

Reduce overproduction and control production volumes through policy and corporate responsibility.
Upcycling and redesign
- Small brands and ateliers deconstruct unsold stock and remake garments (zero‑waste or inventory‑repurposing approaches).
- Designers minimize cutting waste and reuse leftover pieces in new designs.
Reuse of textile waste as building or insulation material (compressed textile panels for interiors/insulation).
Public awareness and individual behavior change: consume less, keep and use clothing longer, and choose more durable fibers.

Notes and caveats

Recycling narratives such as turning PET bottles into textiles can raise demand for waste bottles (causing price effects), do not by themselves address overproduction or end‑of‑life garment disposal, and can create misleading impressions of solving ocean plastic problems.
Quantitative values reported above are those highlighted in the source material; methods and contexts matter for interpretation (e.g., sampling locations, garment types, washing conditions).
