In answer to your question a), blow molded and injection molded plastics
melt at different temperatures from each other. So even though the resin is
the same, they are incompatible when recycled together, at least for high
quality end uses, 'cause you'll either end up with melted plastic with a lot
of chunks in it, or melted plastic that has burned.
