Which of these is NOT a reason to recycle?

• It is the method which uses the least energy

• It is the method that uses maximum resources

• There are consequences for adding the material to landfill

• The materials need sorting before they are able to be rescycled.

Even if a material costs more to recycle than to extract it why might recycling still be the best option?

• Resources are finite

• Resources are deep underground

• Resources need to be processed before they can be recycled

• Resources can not be agregated

PET bottles can be reused as well as recycled. Which of these is a good reason to reuse PET bottles for water?

• PET is a plastic

• Microplastics are now found in the oceans
