2.1 Textile Fibres
Global fibre production in 2016 was estimated to be 94.5 million tonnes, dominated by synthetic
fibres (68.3%) –predominantly polyester (64%) estimated at 64.8
million tonnes, followed by
cotton (22%), man-made cellulosics (6%), and animal-based fibres (1.5%- 80% wool, 20% down)
(Figure 3).
18
Synthetic fibres comprise production from organic
compounds derived from non-
renewable sources (petroleum), and inorganic-based materials (ceramics and glass).
8
Natural fibres
are derived from plants (cellulosics), animal proteins (wool, silk), or minerals (asbestos).

In this
report, four major materials of focus identified based on the synthetics and naturals include:
polyester, nylon, cotton, and wool.

2.2 Textile Waste
It was estimated that the total global apparel waste (83.5 million tonnes in 2015) was greater than 90% of total global fibre production
(94.5 million tonnes in 2016).

Textile waste streams comprise pre-consumer (or post-industrial) waste, and post-consumer waste. Pre-consumer waste includes
materials arising from industrial and commercial processing of textiles or manufacturing of garments (scraps, excess inventory, damaged
or
defective materials, samples). Post-consumer waste includes end-use of products,
such as recalled inventory, items returned or
disposed of by the consumer. Figure 4 depicts general material and common chemical waste streams during
apparel manufacturing and
use.
