Lovely, this works.
I do want to add that not every folium object is pickable, I found Map raises an error:
_pickle.PicklingError: Can't pickle <function root at 0x000002C2924F8310>: attribute lookup root on __main__ failed
But that won't stop this PR, since this is branca-specific. Would be nice though to get it to work for any branca/folium class.

Make
Elementclass (branca.element.Element) pickleable by stripping its ._env attribute when pickling and re-adding it when unpickling. This should address two related issues infolium: python-visualization/folium#878 and python-visualization/folium#796 and has the added implication of being able to create elements concurrently, e.g. usingmultiprocessing.Pool.
