Circular economic engineering through technologization

Abstract

The technologization of circular economy engineering faces barriers in
adoption and training, generating social inequalities. The aim of the study
was to describe circular economic engineering from its technologization.
A comprehensive review of the scientific literature was conducted to
identify and evaluate the relevance of key indicators, which were: I)
technological innovation and sustainability, II) circular economy, III)
socio-economic and environmental indicators, IV) technological model
of circular economy, V) challenges in developing countries, VI) role of
engineering in circular economy, and VII) social implications of circular
economy. The results highlight the assessment of technological innovation
for sustainability; transition towards a circular economic model; positive
socio-economic and environmental impacts; cost reduction and economic
opportunities; technological barriers in developing countries; crucial
role of engineering in circular systems; social implications such as job
creation and social inclusion. It is concluded that circular economy, driven
by technological innovation, promotes process optimization, resource
efficiency, and sustainable solutions; however, barriers in technological
adoption and training persist, indicating the need to adapt technological
models and develop social competencies for an effective transition towards
sustainability.
