Dear all. I got a problem with a new bio-resin. During the degassing, if I fill the the calibrated mixing cup (2440ml) up to 700ml, bubbling is quite large and I got a huge loss of resing, I am attaching a picture to show what is happening. Do you have any advice to avoid the loss of resin? 

How this operation is usually done industrially? Do they use vacuum mixing or something like this?

Thank you in advance for your help.

You need a bigger cup.   Some resins and especially silicones can froth up to several times their original volume, so you need a bigger cup to ensure it does not overflow. 

In some resin casting applications there are vacuum casting machines for pouring under vacuum but that is not applicable to laminating resins.
