Este estudio tiene como objetivo resaltar la importancia del impuesto ecológico en la reducción de la contaminación del aire causada por la industria cementera. El enfoque está en limitar las emisiones resultantes del polvo de cemento y los gases contaminantes que rodean la planta de cemento Lafarge Holcim y sus áreas vecinas. El estudio explora las leyes y decretos argelinos que regulan el impuesto ecológico sobre la contaminación del aire industrial, específicamente los límites de emisión de polvo y gases establecidos por el Decreto Ejecutivo N.º 138/06, que regula la emisión de polvo, partículas sólidas y líquidas, y gases a la atmósfera.Entre los principales hallazgos, se evidenció la efectividad del impuesto ecológico en la reducción de lasemisiones de gases y polvo de cemento en el aire circundante a la fábrica. Esto incluye gases como los óxidos de azufre (SOX), monóxido de carbono (CO) y óxidos de nitrógeno (NOX). Como resultado, la empresa adoptó una política ambientalmente sostenible, invirtiendo en tecnologías de producción más limpias destinadas a reducir las emisiones de gases de efecto invernadero y polvo de cemento. Este enfoque está en línea con el impuesto ecológico sobre la contaminación del aire industrial y demuestra el compromiso de Lafarge Holcim con la sostenibilidad AmbientalPalabras clave: impuesto ecológico sobre la contaminación industrial del aire, tecnologías de producción más limpia, empresa cementera Lafarge Holcim, Argelia.1 INTRODUCTIONIn recent decades, Algeria has experienced a growing industrial revolution, which has led to a decline in air quality and the spread of various diseases that were previously uncommon. This deterioration is primarily due to industrial emissions resulting from the byproducts of production activities, leading to the release of numerous solid pollutants into the air. This pollution has contributed to environmental degradation, negatively impacting biodiversity, ecosystem sustainability, and triggering climate change effects in the region. One notable consequence of this is the rise of the global warming phenomenon.Cement production is one of the most significant sources of air pollution, primarily due to the emission of cement dust and toxic gases, especially sulfur oxides. These gases are produced in high

This study attempts to highlight the role of direct foreign investment on the Algerian economy by highlighting its impact on the growth rates of gross domestic product, in the period between(2000-2021). Therefore, we tried to shed light on the importance of direct foreign investment in the Algerian economy,and algeria is making considerable efforts to benefit of the advantages of direct foreign investment, by following appropriate economic policies . However, the results indicate that Algeria has not reached the required level in order to achieve the goal of increasing in significant economic growth rates. This is due to the weak inflows of direct foreign investment to Algeria

This study attempts to highlight the role of direct foreign investment on the
Algerian economy by highlighting its impact on the growth rates of gross
domestic product, in the period between(2000-2021).
Therefore, we tried to shed light on the importance of direct foreign
investment in the Algerian economy,and algeria is making considerable efforts
to benefit of the advantages of direct foreign investment, by following
appropriate economic policies . However, the results indicate that Algeria has
not reached the required level in order to achieve the goal of increasing in
significant economic growth rates. This is due to the weak inflows of direct
foreign investment to Algeria.

The aim of this study is to emphasize the important role of the reliability and tangibility
dimension, which are considered to be one of the most important dimensions of the quality of the
banking service in terms of impact and increase of competitiveness in Algerian commercial banks,
by caring for the customer who is the most important and dynamic element in commercial banks,
We tested reliability and tangibility by doing two hypothesis tests based on a questionnaire that was
answered by 128 customers in several banks located in Algeria. Finally, we found that reliability,
tangibility has a positive impact on the competitiveness of Algerian commercial banks.
