Figure 1
The flowchart presents three stages labeled “Identification”, “Screening and Inclusion”, and “Data Extraction and Reporting”, followed by a sequence of steps connected by arrows. The “Identification” stage includes boxes labeled “Research Objectives Formulation”, “Document Search”, and “Platform Search”, along with the text “Search engine: Google Scholar” and “Database: Scopus (n equals 331)”connected by rightward arrows. An arrow from “Platform Search” leads to the “Screening and Inclusion” stage, to a box labeled “Initial Title and Abstract Screening (n equals 110)”. To its left is the text “Exclusion criteria: Non-English, not building waste, non-peer-reviewed”. A rightward arrow from “Initial Title and Abstract Screening (n equals 110)”, labeled “Google Scholar (n equals 82), Scopus (n equals 28)”, leads to another box labeled “Full-text Paper Screening; Papers Included (n equals 43)”. An arrow then leads to the “Data Extraction and Reporting” stage, to a box labeled “Themes Formulation”. A rightward arrow from “Themes Formulation” leads to another box labeled “Results and Discussion”.SLR methodology process. Source: Authors' own work
