What's the best thing?
After studying so much I would of course love to do something to use those things for the best of the world. But it starts to look like the most needed innovations don't come out of bioengineering. I wrote my bachelor thesis about microbial fuel cells, which was the most meaningful bioengineering research topic I could find in my university. Microbial fuel cell can basically make electricity out of anything, e.g. sewage. But putting end to sewage as we know it is what should be done rather than using expensive chemicals and infrastructure to take a little bit energy out of it before landfill.
I heard that a lot of this same discussion happened when putting together Finland's national waste plan until 2016. Burning everything would sound so good because it would solve landfill and energy problems at the same time. But if we want to use resources sustainably, in 2016 there should be no more non-recyclable waste to supply for the power plants so why invest on them? I guess this is best to see in a way that there are just endless possibilities to do something good. Even designing technology to take energy out of waste does something, though it would not be the best thing.
