There is no upper limit to the number of unique ideas or plans a contestant may submit. For example, one contestant may submit an idea for a new paper pulping process to the Advanced Manufacturing category and an idea for new paper-making software to the Information Technology category.
A submission can only be entered under one of the four themes, and 3 categories within that single theme.
The same contestant may have more than one idea advance through the competition in one or more categories. Be careful: Multiple entries also means divided time.
However, each submitter can only receive one award for each round. Duplicate awards are not permitted.
