Empty RecycleBin in SharePoint 2010

There are total 2 Recycle bins in every site collection in SharePoint. First Recycle Bin can be called as end user recycle bin which is available in every site & sub-site of a particular site collection. This Recycle Bin is accessible through Site Actions-> View All Site Content. Whenever the user deletes the document, it is stored in this Recycle Bin.

Now, when the document from first Recycle Bin is deleted it gets stored in the Second Recycle Bin which can also be called as Admin Recycle Bin. This is available only at site collection level. This Recycle Bin is accessible through Site Actions-> Site Settings-> Site Collection Administration.

$WebApp=get-spwebapplication "http://sharepoint-site-name"

    foreach ($SPSite in $webApp.Sites)

    {

         #get the collection of webs

      foreach($SPWeb in $SPSite.AllWebs)

         {

             #Empty the 1st Stage Recycle bin items PERMENANTLY which is available in All Site Content

             #$SPWeb.RecycleBin.DeleteAll();

             

             #Send the 1st Stage Recycle bin items to 2nd Stage

             $SPWeb.RecycleBin.MoveAllToSecondStage();

              write-host "End-User Recycle Bin Items Deleted for:"

              write-host $SPWeb.title ":" $SPWeb.URL "`n"
