The recent life - cycle analysis of single serve and traditionaldrip brewing of coffee points out that ground coffee can go stale if it's not used promptly.
A 2015 lifecycle analysis of single serve coffee done by Quantis International identified a series of energy use issues that make single serve often a better choice than traditionaldrip brewed coffee.
