Good question. I have seen some people constantly waste productive time by waiting for the script to finish for 30-50 minutes while going for a coffee, playing a computer game, or watching a video. At the same time, some other scientists constantly waste very little time if any. At least it appears so.
I waste more time some days than on the others. The difference is in motivation and how much energy and focus I have each day. Somehow when I am feeling not good, there are problems in life or I slept very little, it is very hard to change focus and switch task from making a script to reading or writing a paper and back to the scripting in 30 minutes. Some days are harder and I have to patiently watch the script run many jobs for 30-50 minutes and look at the output because I know that if I try to switch to something else it is going to be very hard to do anything meaningful and return to the first task is going to be very long and painful. On such days I try to go for a coffee, change my music to more energetic one and if there is any way to move work to another day for extra hours I ask to leave early.
Very big destruction is meetings. I see myself disorganized right before, during and after the meeting especially if it has very little relation to my work. Some meeting we just have to attend. Those are usually for a bunch of people and these are regular. I use four ways to fight unproductive meetings:
avoid organizing new meetings
avoid going to regular meetings by asking directly when you know there is no need for you for sure
when on the meeting sit far behind, use your laptop if possible or at least use Terminus App on your smartphone to continue working
say little on the meetings, preferably only most important things (do not waste the time of others)
Just recently I found that biostars.com is very interesting place to be while waiting for a task to finish. Thank you BioStars!
I am reasonably certain variations on this have been asked before on Biostars.

Thanks. I've seen this before but I felt like some of them are actual work and some of them are migrating from work. It seems we should break the void context built in our brain for one project to use the time periods like this and built it again when the results are generated. The mentioned example is quite manageable but sometimes it is hard (or more time consuming) when the complex stats are involved.
Taking appropriate breaks (to prevent carpel tunnel syndrome type issues) is important and should fit in that time.
Some have other (managerial/administrative) responsibilities that take up these time slots.
Some even have Fantastic lab work :-(
