Review of sustainability terms and their definitions
Peter Glavič, Rebeka Kovačič Lukman, 2007, izvirni znanstveni članek

Opis: Terminology in the field of sustainable development is becoming increasingly important because the number of terms continues to increase along with the rapid increase in awareness of the importance of sustainability. Various definitions of terms are used by different authors and organizations, for example, green chemistry, cleaner production, pollution prevention, etc. The importance of this topic has stimulated research into the problems of clarifying ambiguity and classifying terms used in the sustainability field. This paper provides results of the literature survey and summarizes the definitions of the terms, focusing on the environmental engineering field. In some cases, it proposes an improved definition. A hierarchical classification of the terms and their relationships has been based on a layer format that is presented graphically.

Water minimization in process industries: case study in beet sugar plant
Lea Žbontar Zver, Peter Glavič, 2005, izvirni znanstveni članek

Opis: In this article, an extended and combined systematic approach for water minimization in process industries is presented. Environmental, organizational and economic aspects of water minimization were taken into consideration. Systematic approach was developed and tested with the water minimization project in a sugar plant. A detailed survey of water and wastewater streams was carried out and several options for water minimization were proposed using the heuristic approach and considering the selection criteria like costs, technical ability, reliability, complexity, impact on process/product quality, secondary waste generation etc. The implementation of water minimization options could lower the fresh water consumption by 54.23 m3/h, reducing the total volume of water used by 69 % with the payback period of 5 days. At the end, some general directions and suggestions for water minimization in process industries are introduced.
