The main barrier to increased mercury substituti<strong>on</strong> is <strong>the</strong> cost of substitutes. Given that <strong>the</strong> costs<br />

of mercury <strong>da</strong>mage for society are not calculated, <strong>the</strong> alternative products and soluti<strong>on</strong>s that are less<br />

c<strong>on</strong>taminating are regarded as too expensive. Some countries of <strong>the</strong> regi<strong>on</strong> have implemented projects for<br />

eliminating mercury use in hospital products. Argentina is c<strong>on</strong>ducting a global pilot project for <strong>the</strong><br />

dem<strong>on</strong>strati<strong>on</strong> and promoti<strong>on</strong> of best practices, which includes <strong>the</strong> eliminati<strong>on</strong> of dioxins (Government of<br />

<strong>the</strong> Republic of Argentina, <str<strong>on</strong>g>20</str<strong>on</strong>g>09). Costa Rica and H<strong>on</strong>duras have also implemented an initiative for<br />

reducing mercury use in hospitals (regarding Costa Rica, see MINAET, <str<strong>on</strong>g>20</str<strong>on</strong>g>09). In order to substitute<br />

mercury with safe inputs in such items as light fittings for liquid crystal displays (LCDs), dental amalgam<br />

and compact fluorescent lamps, or in industrial processes such as chlor-alkali plants, definiti<strong>on</strong>s regarding<br />

waste storage are required as well as corresp<strong>on</strong>ding resources (UNEP, <str<strong>on</strong>g>20</str<strong>on</strong>g>08b). This issue is also relevant<br />

to <strong>the</strong> regi<strong>on</strong>’s ec<strong>on</strong>omy, which presents major opportunities and where progress has been made,<br />

including technology developed by Brazil for deactivating mercury cells in <strong>the</strong> chlor-alkali industry.<br />

Negotiati<strong>on</strong>s for a global c<strong>on</strong>venti<strong>on</strong> <strong>on</strong> mercury will be crucial to <strong>the</strong> future management of<br />

<strong>the</strong> issue.<br />

10. Solid waste management<br />

Solid waste management remains <strong>on</strong>e of <strong>the</strong> critical issues for human safety, especially in urban areas.<br />

The worst problems are poor management of ec<strong>on</strong>omic incentives, low collecti<strong>on</strong> coverage, shortage of<br />

suitable sites for final disposal and use of inappropriate technologies. However, <strong>the</strong>re has been excellent<br />

progress with public policies for solid-waste disposal and management, even though <strong>the</strong> situati<strong>on</strong> is far<br />

<strong>from</strong> optimal. Table II.7 summarizes <strong>the</strong> situati<strong>on</strong> in Latin America and <strong>the</strong> Caribbean.<br />
