    Artificial intelligence assists in sustainability goals up to safety

    The use of Artificial Intelligence has already brought significant gains for Vale in several sectors of the company and has the prospect of advancing even further. Only when talking about sustainability, with the project that reduces the fuel consumption of off-road trucks at the company's units, a reduction of more than 74 thousand tons of CO2 per year is expected. The initiative contributes to Vale's goal of reducing direct and indirect emissions by 33% by 2030.

    Security, another key factor for the company, has also been contemplated with an artificial intelligence project. One of the project lines is the prediction of equipment failures, which increases employee safety and business productivity. The system works by capturing data from sensors installed in the equipment and other operation variables. After analyzing this information, with the support of mathematical models, insights are generated that help to predict when equipment may fail. In this way, it is possible to avoid the breakage of equipment, which can cause losses to the business, but mainly damages to employees of the operation.

    In the face of so many gains, Vale launched its first Artificial Intelligence Center (AI Center), in Vitória, Espírito Santo. The space is used to develop and monitor the initiatives of this science both in the company's units in Brazil and in other countries. The benefits are obtained by optimizing asset maintenance, improving the management of ore beneficiation and pelletizing plant processes; and improving environmental, health and safety and corporate integrity controls.

    An error occurred while processing the template. 
    The following has evaluated to null or missing:
==> restClient.get("/headless-admin-taxonomy/v1.0/sites/" + groupId + "/taxonomy-vocabularies?filter=name eq 'News topics' or name eq 'Temas de notícias'&fields=id&restricFields=actions,availableLanguages&page=1&pageSize=1").items  [in template "44549#44620#460359" at line 4, column 29]

----
Tip: It's the step after the last dot that caused this error, not those before it.
----
Tip: If the failing expression is known to legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing</#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??
