In 2020, the project began testing a new block prototype that uses eggshell waste, sand, pebbles, and cement, stabilized with iron rebar.<sup id="cite_ref-Pondicherry_163-0" class="reference"><a href="#cite_note-Pondicherry-163"><span class="cite-bracket">&#91;</span>163<span class="cite-bracket">&#93;</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="Dubai">Dubai</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Artificial_reef&amp;action=edit&amp;section=40" title="Edit section: Dubai"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Pearl of Dubai is an art-inspired Lost City off the coast of <a href="/wiki/Dubai" title="Dubai">Dubai</a>.
