Abstract
Investigations on the application of Life Cycle Assessment (LCA) to the construction sector have shown that the environmental impact of construction products can be significantly reduced. To achieve this, the use of best available techniques and eco-innovation in production plants must be promoted. In this way, the use of finite natural resources can be replaced by waste generated in other production processes, preferably available locally, stimulating the creation of more sustainable products. Conducting a comparative LCA study between the traditional ceramic brick manufacturing process and the ceramic brick manufacturing process incorporating ‘alperujo’ (waste generated in the virgin oil extraction process), is an inevitable step to achieve the integration of circularity and eco-innovation in the production system of traditional ceramic materials, through the CML(Centrum voor Milieukunde Leiden) and IPCC(The Intergovernmental Panel on Climate Change) methodology. The obtained results suggest that the environmental benefits in this practice are very limited, even taking into account the contribution of different amounts of this waste to the production of bricks.

The main objective of the present work is to carry out a comparative study of the Life Cycle Assessment (LCA) of traditional ceramic materials with respect to sustainable ceramic materials manufactured with olive pomace, waste generated in the virgin oil extraction process, which allows us to determine the global impact of the life cycle of the different products evaluated
Summary
Human influence on atmospheric quality has been increasing in recent years. If left unchecked, through the use of rigorous mitigation activities, climate change will increase the likelihood of severe, widespread, and irreversible impacts on people and ecosystems [1]. The need to transform the construction sector involves reducing emissions of polluting gases through the use of new materials with a low or zero carbon footprint and, in addition, promoting the progress of the circular economy by reusing and incorporating materials from waste. It is more than evident the necessary transition from the current linear production system to a production system based on a circular economy that allows the search for new alternatives with the main objective of curbing the consumption of natural reserves and the increase of CO2 emissions, as well as moving towards greater sustainability [3,4]
