My processor factory output is full and factories have nowhere to ship freight. How do I fix that?

I have 1 small trade depot which has 1 coal storage lot, 1 ore storage lot and 1 freight storage lot. I cannot add any more storage lots to my trade depot.

I have 1 big trade pot which only has 1 freight storage lot, and I cannot add more storage because it says "NOT APPROVED".

Also, my whole city has High TECH level, university running at full and 1 Electronics HQ, which earlier used to say NEED ALLOY Import from global, but somehow I fixed it with Recycling center.

Electronics HQ now has produced too much and its OUTPUT STORAGE is full. Same problem now arising to my factories "Closing because of no places to ship freight."

How can I fix my FREIGHT SHIPPING problem? I have no place for Municipal airport. How do I allow my factories to ship freight and my processor factory to sell processors?

I have 10,000,000$+ money and Income is 13500$ per/hr. Population is 100,000.
