Yes, drinking pre workout is eco-friendly. Most athletes or bodybuilders prefer powdered pre workouts since they can simply mix it with water and consume it. This means there's no packaging waste and it's more efficient since you're not having to take multiple pills. Additionally, you can control how much you're taking and it's easy to transport. However, those that are in pill form are just as eco-friendly since they can be stored in a glass jar and reused.
