Abstract(s)
No presente trabalho, efetuou-se a avaliação de ciclo de vida de produção
de 1 tonelada de agregado artificial de escória, resultante da valorização,
como material de construção, da fração residual do processo de
valorização energética de resíduos urbanos na LIPOR II, e comparou-se
com a produção de agregado britado de origem natural. Com este estudo,
pretendeu-se reforçar a validação com marcação CE do agregado
artificial de escória que está em desenvolvimento.
O estudo tem em conta que a utilização será regional, tendencialmente
nos municípios associados da LIPOR, sendo a avaliação de ciclo de vida
aplicada na obtenção de matérias-primas, nos resíduos urbanos, e a
entrega em obras nos locais estimados na área geográfica indicada. Este
estudo foi feito, observando a normalização aplicável, nomeadamente as
normas da série ISO 14040, e com ferramenta de cálculo OPENLCA,
usando a informação disponibilizada pela LIPOR II relativa à operação e
dados secundários provenientes de bases de dados como a
ECOINVENT.
As categorias de impacto consideradas foram os presentes nos modelos
CML IA, IMPACT 2002+ e EN 15804.
In this work, has been developed a life cycle assessment of the production of 1 ton of artificial aggregate, resulting from the recovery, as a building material, of the residual fraction of the waste to energy process at LIPOR II, and compared with the production of crushed aggregate of natural origin. With this study, it is intended to reinforce the validation with CE marking of the artificial slag aggregate that is under development. The study focuses on regional use, tending to be in the associated municipalities of LIPOR, with the life cycle assessment oriented between the obtaining of urban waste, as raw material, and delivery in siteworks in the estimated locations in the indicated geographical area. The study was conducted in accordance with applicable standardization, including ISO 14040 series, and with the use of the OPENLCA calculation tool, using information provided by LIPOR II related to operations and secondary data from databases such as ECOINVENT. The impact categories considered were those present in the CML IA, IMPACT 2002+, and EN 15804 standard.
