**1. Introduction**

Numerous pathways and narratives have been developed to shed light on how society could transform its production systems in line with the aspirational targets of the Paris Agreement and Sustainable Development Goals. Green technologies, as an emerging technical innovation, are necessary for driving the production system transformation that is called for global sustainability. Key potential benefits of green technology are that they might substantially reduce the cost of mitigating CO2 emissions and improve the environment performance with the development of more affordable, better-performing technologies.

The scope of the *Processes* journal covers research in chemistry, biology, materials, and allied engineering fields. Thus, in this Special Issue, we invite articles focused on research regarding the chemistry, biology, materials, and allied engineering firms (manufacturing processes, iron and steel production processes, mining processes, power generation processes, and so on).

This Special Issue on "Green Technologies for Production Processes" will focus on publishing original research works about Green Technologies for Production Processes, including discrete production processes and process production processes, from various aspects that tackle product, process, and system issues in production. The aim is to report the state-of-the-art on relevant research topics and highlight the barriers, challenges, and opportunities we are facing. It also welcomes studies that stimulate research discussion of moving towards production in a particular industrial sector. Topics of interest for this Special Issue include but are not limited to:
