I found this phrasing confusing. From the article you linked,

>> Aluminum can be recycled using less than 5 percent of the energy used to make the original product. (EPA)

I would say that's more efficient by 95%. (Thank you for providing the link!)

Well, if you're using less than 5% of energy, that means with the same amount of energy you can make 20x. So I'd say it's actually 1900% more efficient.

Yes, you are right! Each bullet point on their site tried to word it slightly differently so it was a little confusing. I messed up translating the aluminum one clearly. Thanks for pointing it out!
