Low-Carbon Cement with Waste Oil-Cracking Catalyst Incorporation

The present paper shows preliminary results of an ongoing project which one of the goals is to investigate the viability of using waste FCC catalyst (wFCC), originated from Portuguese oil refinery, to produce low carbon blended cements. For this purpose, four blended cements were produced by substituting cement CEM I 42.5R up to 20% (w/w) by waste FCC catalyst. Initial and final setting times, consistency of standard paste, soundness and compressive strengths after 2, 7 and 28 days were measured. It was observed that the wFCC blended cements developed similar strength, at 28 days, compared to the reference cement, CEM I 42.5R. Moreover, cements with waste FCC catalyst incorporation up to 15% w/w meet European Standard EN 197-1 specifications for CEM II/A type cement, in the 42.5R strength class.

A problemática da dicotomia contabilística ao nível dos subsídios ao investimento

A globalização dos mercados, articulada com a abertura das fronteiras dentro da União Europeia, e com a diversidade de sistemas contabilísticos, acentuou a necessidade de criar um único sistema contabilístico que fosse aceite internacionalmente e, ao mesmo tempo, que facilitasse o acesso aos mercados de capitais internacionais. O novo Sistema de Normalização Contabilística (SNC) adotado em Portugal é baseado essencialmente em princípios, conduzindo à existência de novos conceitos e à necessidade de incorporar novas formas de entender a contabilidade. Constata-se que os procedimentos contabilísticos impostos pelo SNC, no caso particular da Norma de Contabilidade e Relato Financeiro (NCRF) 22 - Contabilização dos Subsídios do Governo e Divulgação de Apoios do Governo, são mais exigentes e pormenorizados do que os previstos no anterior sistema normativo nacional, em vigor até 31/12/2009. Verifica-se ainda que esta norma, no que diz respeito ao tratamento contabilístico dos subsídios relacionados com ativos, não segue o preconizado na atual International Accounting Standard (IAS), ou Norma Internacional de Contabilidade (NIC) 20 - Contabilização dos Subsídios do Governo e Divulgação de Apoios do Governo. Pretende-se assim analisar as referidas normas, enumerando as suas principais diferenças, e constatar como os outros países da União Europeia contabilizam estes subsídios. The globalization of markets, combined with the opening of borders within the European Union, and the diversity of accounting systems, emphasized the need to create a single accounting system that is internationally accepted and at the same time, improving access to markets international capital. New Accounting Standards System adopted in Portugal is essentially based on principles leading to the existence of new concepts and the need to incorporate new ways of understanding accounting. It appears that the accounting procedures required by the SNC, particularly in the case of NCRF 22 - Accounting for Government Grants and Disclosure of Government Assistance, are more stringent and detailed than those of the preceding national regulatory system in force until 31/12/2009. It also appears that this standard with regard to the accounting treatment of grants related to assets, does not follow the recommendations in the current IAS 20 - Accounting for Government Grants and Disclosure of Government Assistance. The aim is to analyze the standards, enumerating the main differences, and see how the other UE countries account for these allowances.
