Figure 6
Two network graphs illustrate the interrelationships of keywords refuse-derived fuel (RDF) and solid recovered fuel (SRF) with other clusters. Panel A on the left shows the connections of RDF with various other keywords and clusters. The central node labeled RDF is connected to multiple surrounding nodes representing different keywords such as waste, energy, incineration, and municipal solid waste. The connections are color-coded, with different colors indicating different types of relationships or strengths of connections. Panel B on the right depicts the connections of SRF with other keywords and clusters. Similar to Panel A, the central node labeled SRF is connected to various surrounding nodes representing keywords like waste, energy, incineration, and municipal solid waste. The connections are also color-coded, indicating different types of relationships or strengths of connections.Illustration of interrelationships of (a) RDF, (b) SRF. Source: Authors' own work
