Mass Balance & Waste generation

chemeguy

Hello everyone!

So I'm working on constructing a simple mass balance for a cake. I didn't have any problems doing that, but I was asked about waste that is generated in the process of making the cake. Is there really a waste generated in this kind of process? I've also been asked to discuss how the amounts of waste generation changes when it is being produced in a factory setting.

Here is the materials that I'm using for the cake:

Flour, eggs, oil, water, baking powder and heat

I was thinking that egg shells will be generated as waste. Thats all I came up with.

Please give me some advice if you have any. Thanks.

Coming from the compounding side there is more waste than you would think.

Any powdered material will be sucked into the dust collection system. Oil/water will get spilled, eggs will be broken etc. I think you can safely say 1-2% is lost as waste.

Water will also be evloved in the baking as water vapor.

And is every cake removed completely from the pan?

Thanks a lot for the help. I have a better understanding of what to do now. Thank you.
