%0 Journal Article %T Extraction Factory for Palm-Tree Fat to Produce Biodiesel [O Crescente uso de Poliuretanas Derivadas do ¨®leo de Mamona no Mercado de Pol¨ªmeros] %A Hugo F. Ramalho %J Revista Virtual de Qu¨ªmica %D 2013 %I Sociedade Brasileira de Qu¨ªmica %X The traditional use of oil-based poliols is being systematically replaced by castor oil for the polyurethane production. This new application appears as an alternative to the failed use in the biodiesel industry, giving a second chance to the castor-bean oil production system. As a consequence, the objective of regional development proposed by the Brazilian government can still work resulting in financial profits since castor-bean oil is being used to make products with higher aggregate values. %U http://www.uff.br/RVQ/index.php/rvq/article/view/361/304
