PET plastic is everywhere, from water bottles to clothing fibre. Not every use of it is actually a good idea.
🏛️ Must Know
What PET Can and Cannot Safely Do
- Blends With Wool and Cotton PET fibres genuinely can be blended with wool and cotton fibres to reinforce their properties.
- Not Safe for Every Alcoholic Beverage PET containers cannot safely store any alcoholic beverage. Some drinks can leach chemicals from PET, especially at higher alcohol content or temperature.
- Genuinely Recyclable Bottles made of PET can genuinely be recycled into other products, making it one of the more recyclable common plastics.
- Incineration Still Emits Greenhouse Gases Incinerating PET is not emissions-free. Burning it still releases greenhouse gases into the atmosphere.
