my %Env = ('PPA_CURRENT_PROJECT' => 'D:\Projects\CurrentProject' => 'Directory', ...

Hashes store and are initialized from key-value pairs, not triples.  I.e., you probably rather want a data structure like this:

my %Env = ('PPA_CURRENT_PROJECT' => [ 'D:\Projects\CurrentProject' => 
+'Directory' ], 
           ...

or

my %Env = ('PPA_CURRENT_PROJECT' => { 
                   value => 'D:\Projects\CurrentProject',
                   type  => 'Directory' 
               }, 
           ...

With the latter, you could, for example, access the type using

  $Env{PPA_CURRENT_PROJECT}{type}
