Abstract
Abstract
In recent years, issues related to the impact of human activity on the natural environment have become pressing, and the challenge of global warming necessitates immediate action. To support environmental protection efforts, it has become imperative to adopt a broader perspective when evaluating various products and systems. A valuable tool for such assessments is a life cycle assessment (LCA), which enables a comprehensive analysis of the entire life cycle of a product.
This paper presents a comparative analysis of the hull of a fast patrol craft, fabricated using three different materials: steel, aluminium, and composite materials. The LCA covers every stage from material production, through the construction and use of the hull, to its eventual disposal. A specific criterion was established to evaluate the impact of the hull on the environment, with clearly defined system boundaries.
In the final section, we draw some conclusions that underscore the importance of reusing construction materials. By emphasising this approach, ecological footprints can be minimised and a sustainable future can be created.
