The environmental impact of waste glass WG is one of the major challenges crippling sustainable waste management and mitigation Reclamation of recycled materials from waste glass remains a tedious task amidst complex technological approaches The challenge as seen in the global containment measures increase the proportion of waste glass and minimize
Definition of C&DW C&DW term is defined as the solid waste generated from CRD works such as land excavation or foundation civil and building construction site cleaning demolition events roadwork and building renovation which are the main causes of C&DW generation [35 36 37 38 39] Tchobanoglous et al [] stated that demolition wastes are yielded
The Charging Scheme The legislation for the Construction Waste Disposal Charging Scheme Charging Scheme was enacted in January 2005 Construction waste means any substance matter or thing that is generated from construction work and abandoned whether or not it has been processed or stockpiled before being abandoned but does not include any
Firstly LCA allows for a thorough evaluation of the environmental impacts associated with construction materials By considering the entire life cycle of these materials from extraction to disposal LCA provides a comprehensive understanding of their environmental footprint [107] [109] [185] This insight enables decision makers to identify the most significant
Microplastics can be divided into primary and secondary groups Primary microplastics are the particle waste products generated throughout the production process Carpenter et al 1972 Secondary microplastics are the small debris generated from the degradation of larger plastic materials as a result of mechanical strain hydrolysis oxidation
