Abstract
Dans un contexte de pression environnementale croissante, la gestion des déchets ménagers solides représente un défi majeur pour les collectivités et les industries.
Cette étude propose une alternative innovante : la valorisation de ces déchets dans la fabrication de bétons écologique, À travers une approche expérimentale simulée, différents types de déchets (plastiques, verre) ont été intégrés dans des formulations de béton afin d’en évaluer les performances mécaniques, physiques et environnementales.
Les résultats montrent que certaines substitutions partielles permettent d’obtenir des bétons adaptés à des usages non structurels, tout en réduisant la consommation de matières premières vierges et les émissions de CO₂.
L’étude souligne également les limites techniques et sociales actuelles, et propose des recommandations concrètes pour une mise en œuvre à plus grande échelle.
Ce travail s’inscrit ainsi dans une dynamique de développement durable et d’économie circulaire dans le secteur du bâtiment.
Amid growing environmental pressures, the management of household solid waste presents a major challenge for municipalities and industries. This study explores an innovative alternative: valorizing these wastes through their integration into eco-friendly concrete production. Using a simulated experimental approach, different types of waste (plastics, glass) were incorporated into concrete formulations to assess their mechanical, physical, and environmental performance. The results demonstrate that certain partial substitutions allow the production of concrete suitable for non-structural applications, while reducing the consumption of raw materials and CO₂ emissions. The study also highlights current technical and social limitations and provides practical recommendations for broader implementation. It contributes to the promotion of sustainable development and circular economy practices in the construction sector.

في ظل التحديات البيئية المتزايدة، تُعدّ إدارة النفايات المنزلية الصلبة من أبرز الإشكاليات التي تواجهها الجماعات المحلية والقطاعات الصناعية. تقترح هذه الدراسة بديلًا مبتكرًا يتمثل في تثمين هذه النفايات عبر دمجها في تصنيع خرسانة صديقة للبيئة. من خلال مقاربة تجريبية محاكاة، تم إدماج أنواع مختلفة من النفايات (البلاستيك، الزجاج) في تركيبات خرسانية لاختبار أدائها الميكانيكي والفيزيائي والبيئي. وقد بينت النتائج أن بعض نسب الاستبدال الجزئي يمكن أن تنتج خرسانة مناسبة للاستعمالات غير الإنشائية، مع تقليل استهلاك الموارد الطبيعية وانبعاثات ثاني أكسيد الكربون. كما تطرقت الدراسة إلى التحديات التقنية والاجتماعية الحالية، واقترحت توصيات عملية لتوسيع نطاق التطبيق. وبذلك، تندرج هذه الدراسة ضمن توجه مستدام قائم على الاقتصاد الدائري في قطاع البناء.
