People always threw away the PET bottle with cap, but less people knows it is very dangerous in the PET bottle recycling process. This is not because the bottle cap can not be reclaimed, the reason is the bottle raw material and cap material is different. The bottle is made of PET(polyethylene terephthalate), and the cap is made of PP (Polypropylene) ,PE (Polyethylen). When these two kinds product be reclaimed together, it just like one material polluted another material and at the same time reduce the recycling material using value.
The other very important factor is when the PET bottle with cap be process in the recycling center, cap will probably block the machine.Generally, the PET bottle will be squashed and packed during the transportation. If the PET bottle was fixed tightly with cap and there is also some air in the bottle, so when the process center melting temperature goes up, the PET bottle will explode and hurt the recycling center working staff.
Therefore, it is our responsibility to separate the PET bottle from the bottle cap before the PET bottle recycling.
