Influence of the impact assessment method on the conclusions of a LCA study. Ap...

Recent legislation has stressed the need to decide the best end-of-life (EoL) option for post-consumer products considering their full life-cycle and the corresponding overall environmental impacts. The life cycle assessment (LCA) technique has become a common tool to evaluate those impacts. The present study aimed to contribute to the better understanding of the application of this technique, by evaluating the...

Laboratory study on the leaching potential of spent alkaline batteries

Four different leaching tests were carried out with spent alkaline batteries as an attempt to quantify the environmental potential burdens associated with landfilling. The tests were performed in columns filled up with batteries either entire or cross-cut, using either deionized water or nitric acid solution as leachant. In a first set of tests, the NEN 7343 standard procedure was followed, with leachant circul...

Laboratory study on the behaviour of spent AA household alkaline batteries in i...

The quantitative evaluation of emissions from incineration is essential when Life Cycle Assessment (LCA) studies consider this process as an end-of-life solution for some wastes. Thus, the objective of this work is to quantify the main gaseous emissions produced when spent AA alkaline batteries are incinerated. With this aim, batteries were kept for 1 h at 1273 K in a refractory steel tube hold in a horizontal ...

A incineração de resíduos em Portugal

Esta comunicação tem como objectivo apresentar a situação da incineração de resíduos em Portugal. Serão abordados os diferentes tipos de resíduos que, em Portugal, são sujeitos a este processo de tratamento - urbanos, industriais, hospitalares e florestais e, para cada tipologia, é inicialmente apresentada a situação em termos de produção e destino final e de seguida a identificação das unidades de incineração ...
