I am student at the University of Michigan and I am trying to set up a device that I could use for vermacomposting during winter here(It is really cold, it can get as low as -20 degrees Celcius). The setup will sit outside in the cold, so I may need artificial heating.

Why set it outside ? Because I am trying to create a chain wherby the waste from the Dorms will be brought in trucks and dumped into the Vermacomposting unit.

If anyone has any ideas of a good design that I can implement, please let me know.

Thanks
