The video tutorial explains the process of recycling plastic bottles into fibers. It begins with collecting and sorting plastic bottles, which are then washed and chopped into chips. These chips are heated using rice husks as fuel and extruded into fine filaments. The filaments are stretched and opened using recycled water, eventually being spun into yarn and dyed. The process emphasizes sustainability by using recycled materials and minimizing water usage.

Explain the process of extruding the molten plastic.
