  <dc:description>&lt;p&gt;&lt;span&gt;Large amounts of limestone fines co-produced during the processing of crushed limestone may be useful in the sequestration of carbon dioxide (CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;). Accelerated weathering of limestone (AWL) is proposed as a low-tech method to capture and sequester CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;from fossil fuel-fired power plants and other point sources such as cement manufacturing. AWL reactants are readily available, inexpensive and environmentally benign. Waste CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;is hydrated with water to produce carbonic acid. This reacts with and is neutralized by limestone fines, thus converting CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;gas to dissolved calcium bicarbonate.&lt;/span&gt;&lt;/p&gt;</dc:description>
