PET bottles are collected by informal waste collectors, as well as formal recycling businesses across the country. The plastic bottles are taken to Extrupet, who wash and chop the bottles into chips or flakes. These chips are used in food-grade application to make new bottles made out of rPET (recycled PET bottles) or are sent to Propet. Propet converts the chips into small pellets, which are extruded through their machines to produce fibre. This fibre is used in the manufacture of the nonwoven felt, as well as many other fibres such as duvet and pillow inners, and even knitted into t-shirt fabric.
