The concept of unit operations over time and subsequent concepts in chemical technology has evolved into a unified field of separation processes and sustainability in this field (and its significance for the chemical and process industry) is of particular interest, not only scientifically, as, for example, the need for fresh sources of drinking water is becoming urgent worldwide. We certainly need the traditional raw materials in many everyday products, and for our computers, among other uses. Generally, the idea in the present issue – also according to the green chemistry principles – is to design processes to maximize the amount of raw materials in products, while being environmentally safe and energy efficient, and avoiding waste production. It should be noted that two contrasting perspectives have been adopted in the area: one states that continued extraction of non-renewable resources is a necessary part of sustainable development, whilst the other states that extraction of these resources must be greatly reduced or even eliminated. Green technologies are environmentally friendly operations that limit the negative impacts of traditional industrial activities and can contribute to addressing the challenge of sustainable management.
There has been much talk, from various perspectives (including even political), about going green. The explosion in the number of recent relevant publications may be explained by this heightened interest. For instance: ionic liquids were used in the extraction of phenolic compounds from bio-oils. Ionic liquids, also termed “green” and “designer” solvents, were proposed as promising solvents for diverse applications, including metal extraction. The economic aspect of the recovery of useful valuable minerals or metals, contributing to recycling meanwhile with environmental technology constitutes the focus of various applications. Microfluidics offered a continuous nanoparticle separation approach. Green thin-film nanocomposite membranes showed enhanced separation properties, thanks to the additional pores or channels offered by these nanomaterials for water purification. An ultrasound-assisted catalytic transesterification process was developed for biodiesel (which is greener compared to petroleum diesel and renewable) production. A number of technologies for the conversion of lignocelluloses into gas, liquid, and solid fuels, as well as platform chemicals, are being researched (i.e., for the production of green diesel and gasoline).
Green environmentally friendly adsorbents from agro-food wastes were also synthesized and tested – i.e., for the treatment of pharmaceutical effluents. Green synthesis of amino-functionalized carbon nanotube-graphene hybrid aerogels was prepared for high-performance heavy metal ion removal. Membranes based on functionalized ionic liquids also attracted attention for CO2 (which mainly comes from flue gas, natural gas, and syngas) separation. Various guidance tools and practices have been proposed to improve the sustainability of mining activity, while maintaining the economic viability. Tightening environmental regulations and increasing awareness for the need to protect ecosystems have effectively resulted in an increased interest in the alternative use of biosurfactants. There has been phenomenal progress in flotation chemistry and chemicals – both in design and manufacture; there are also many new concepts and tools that can be capitalized. The above brief introduction justifies the importance of this Special Issue.
