Bulk Trash by URL helps editors and SEOs quickly clean up content by trashing items based on a list of URLs. Paste your URLs, let the plugin map each URL to a post ID (handles common variations like trailing slashes and marketing query params), select what you want to remove, and process in efficient batches with progress feedback.
Key features:
<ul>
<li>Paste URLs to find matching posts, pages, and custom post types.</li>
<li>Fast URL-to-post mapping in AJAX batches with progress bar.</li>
<li>Select exactly which items to trash before running.</li>
<li>Batched trashing with live progress, pause/resume controls.</li>
<li>Optional completion summary with counts and lists (trashed, failed, no permission, invalid).</li>
<li>Settings to tune performance and limits:
<ul>
<li>Max Page Size (mapping batch size)</li>
<li>Max URLs per run</li>
<li>Toggle completion summary</li>
<li>Optional mode to set matched items to Private instead of Trash</li>
</ul>
</li>
</ul>
Built for large lists and long-running jobs. Everything goes to the WordPress Trash, so you can restore or permanently delete as you normally would.
Capabilities & security:
<ul>
<li>Restricted to users who can <code>manage_options</code>.</li>
<li>Nonce-protected AJAX endpoints.</li>
<li>Conservative sanitization and server-side validation.</li>
</ul>
Compatibility notes:
<ul>
<li>Works with sites using pretty permalinks. Mapping relies on WordPress <code>url_to_postid()</code> and common URL variants.</li>
<li>Custom post types are supported if they use public, front-end URLs.</li>
</ul>

Mark-k

Once a day wordpress deletes all trashed items which had been in the trash for more then N days, where N stands for the value of EMPTY_TRASH_DAYS constant which may be defined in wp-config.php file.
This plugin presents a different way to control the number of trashed days. Instead of manually editing wp-config.php which is usually not convenient and somewhat dangerous, you can set the number of days in a settings page. 
In addition there is a tool to empty the cache from Items older the a specified number of days.
Usage: 
Get to the settings page via the menu “Options” >> “Empty trash” 
Get to the delete trash tool page via the menu “Tools” >> “Empty trash”
Network considerations: 
The plugin was not tested in a network installation, but it should work gibing the individual site admin a control over his trash which is possibly different then other sites on the network. 
The plugin do not have network wide settings
Important: 
For better or worse the plugin employs exactly the same deleting algorithm used by the wordpress version running the site.
Limitations: 
The plugin will not be able to function well if you have EMPTY_TRASH_DAYS set in your wp-confing.php

Trash emptier

Provides a configurable control over the trash emptying algorithm wordpress uses without changing wp-config.php
