A combined tool for environmental scientists and decision makers: ternary diagrams and emergy accounting

Is the hydrogen production from biomass technology really sustainable? Answer by life cycle emergy analysis

“…When ESI < 1, the corresponding product or process is not sustainable in the long term, when 1 < ESI < 5, the corresponding product or process has a sustainable contribution to the economy for medium periods and the product or process with ESI > 5 can be recognized as sustainable in the long term [6].…”

Multicriteria cost–benefit assessment of tannery production: The need for breakthrough process alternatives beyond conventional technology optimization

“…Finally, these flows are combined for the calculation of total emergy "U" and emergy indices (Fig. 3), which help to draw conclusions about system's performance -at this point, the ternary diagram as proposed by Giannetti et al (2006) and later described in detail by Almeida et al (2007) could be helpful for a graphical interpretation of the assessed systems.…”

Emergy Synthesis and Regional Sustainability Assessment: Case Study of Pan-Pearl River Delta in China

“…The concept of ternary diagrams was proposed by Gibbs and Roozeboom for the analysis of mixed components and introduced into emergy synthesis by Giannetti et al [13]. The representation of emergy values on the ternary diagram allows prompt visualization of the results and facilitates comparison among provinces in PPRD.…”
