Home composting question: high quantities of egg shells per week (beehaw.org)

We have a household of two and I just started a 43 gallon capacity rotating composting bin. Our weekly egg consumption is high and there's an additional load of volunteering (baking) where I have to dispose of 2-3 dozen egg shells at a time.

What's the maximum number of shells I can expect to toss in the compost each week? Any ideas on how to dispose of the rest without going right to the trash? We only have recycling and yard debris pickup, no city compost options. Thanks in advance!

Almost nothing in your household consumes as much energy as an oven. Ovens consume from around 1000 (when already heated up) to 5000 Watts leading to ginormous amounts of carbon emissions on your average electricity mix. From an environmental perspective it's completely crazy to bake your trash for 30 to 40 minutes (it's like running your electric kettle at full power for 30 minutes straight). I'd rather not compost eggshells at all rather than baking them.

I have my oven on at least a few times a week to bake, often every day. And much of the year, it simply means my furnace will run less. OP is baking semi-commercially, they'll have plenty of preheating time to borrow.
