It would be difficult estimating the solid waste produced. For one, the nutrients would be suspended in the medium, so it would be akin to figuring out how much solid sugar is in your can of coke without looking at the label. And two, it would depend on how much nutrients Bolt threads is adding. They probably have figured out the optimum amount of sugar needed for their process. They've chosen to use corn for their sugar source, which they would likely need to use an enzyme to break it down to usable sugar to feed the yeast. Their founder says they buy corn in truck loads. Which I feel would be fine if they weren't using it to make a product with such low yields. That corn, or water used to grow the corn could be going to other uses, like feeding people or animals.

The issue about their waste also gets more complicated when you consider what they need to do to dispose of it. They can't just pour it down the drain like they would in their labs. That many nutrients can cause downstream eutrophication which can be deadly to complex marine organisms. Their waste would likely need to be treated. Another expense that arises during scale-up for their process.

I'm not sure if this was helpful to your original question
