Integrating environmental and economic life cycle analysis in product developme...

Simões, Carla L.; Pinto, Ligia M. Costa; Simoes, Ricardo; Bernardo, C.A.

Purpose Achieving sustainability by rethinking products, services and strategies is an enormous challenge currently laid upon the economic sector, in which materials selection plays a critical role. In this context, the present work describes an environmental and economic life cycle analysis of a structural product, comparing two possible material alternatives. The product chosen is a storage tank, presently ma...

The quest for a sustainable product: An environmental study of tyre recyclates

Simões, Carla L.; Simoes, Ricardo; Carvalho, José; Pontes, António J.; Bernardo, C.A.

The main objective of the present study is to assess the environmental advantages of substituting aluminium for a polymer composite in the manufacture of a structural product (a frame to be used as a support for solar panels). The composite was made of polypropylene and a recycled tyres’ rubber granulate. Analysis of different composite formulations was performed, to assess the variation of the environmental im...

Energy recovery and impact on land use of Maltese municipal solid waste inciner...

Pirotta, F. J. C.; Ferreira, E. C.; Bernardo, C. A.

An investigation of the potential of Maltese Municipal Solid Waste (MSW) for energy recovery is carried in this work together with a preliminary assessment of the corresponding economic and land use impacts. MSW composition data was collected to evaluate the waste combustion enthalpy. Data from 1997 to 2010 allowed the conclusion that an incinerator with a capacity of 32,500kg/h can treat all the waste expectab...


Environmental consequences of Maltese MSW incineration

Bernardo, C. A.; Pirotta, F. J. C.; Ferreira, E. C.

The intensity of Municipal Solid Waste (MSW) generation by human and economic activities causes environmental impacts, particularly critical in small insular countries, such as Malta. Thus, an investigation of the potential of Maltese MSW incineration with energy recovery was performed in this work focused on thermodynamic and land use aspects. The electricity potential of an MSW incinerator with associated ele...


Potential for energy recovery from maltese MSW : a thermodynamic analysis

Pirotta, F. J. C.; Bernardo, C. A.; Ferreira, E. C.

An investigation of the Maltese Municipal Solid Waste (MSW) potential for energy recovery is carried in this work. In a first step, MSW composition data was collected to evaluate the waste combustion enthalpy by a weighted average of each fraction, using the corresponding Low Heat Value (LHV). Results indicate that each kilogram of Maltese MSW releases circa 8,726 kJ of energy when combusted. Data from 1997 to ...


Thermoplastic matrix composites from towpregs

Silva, J. F.; Nunes, J. P.; Bernardo, C. A.; Marques, A. T.

In recent years, continuous fibre reinforced thermoplastic matrix composites have been successfully employed in the aircraft, military and aerospace industries due to the excellent properties (Brandt et al. 1993 & Nunes et al 2005a). In these and many other commercial engineering applications, they can replace other materials, such as thermosetting matrix composites. However, the high cost of the impregnation o...


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

Simões, Carla L.; Xará, Susana M.; Bernardo, C. A.

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...



The use of a three-point support flexural test to predict the stiffness of anis...

Nunes, J. P.; Pouzada, A. S.; Bernardo, C. A.

Anisotropic polymeric matrix composite discs supported on three points were subjected to a non-destructive bending test to study their behaviour in complex flexural loading situations. The results show that the flexural behaviour of the composites depends on several factors, such as fibre orientation, laminate stacking, surface waviness and moulding temperature. The experimental data were compared with those ob...
