SYNTHESIS OF SUSTAINABLE BIOPROCESSES USING COMPUTER-AIDED PROCESS ENGINEERINGLidija Čuček
, 2013, doktorska disertacija
Opis: This doctoral dissertation, which consists of four substantive wholes, presents several syntheses of sustainable bioprocesses using computer-aided process engineering. In the first part the synthesis of different integrated processes of ethanol production from the entire corn plant is presented. The synthesis of different processes is in the second part further extended to the simplified and more comprehensive synthesis of bioproducts in the whole production supply chain network. Synthesis is based on the generic optimisation model of biomass production and supply chain networks.
In the third part three methods for sustainable development assessment, suitable for multi-criteria optimisation, are presented: method of sustainability indexes, footprints and combined criteria, such as eco- and total profit. Methods are further upgraded with indirect effects in order to measure the unburdening the environment, associated with the use and replacement of environmentally-harmful products. Methods include the direct, indirect and total impacts on the environment.
In the last part the methodology for reducing a large number of criteria within multi-objective optimisation to a small number of representative criteria is presented. This method is presented on the case of environmental footprints.

Green Business - A Business of SustainabilityŽan Kokalj
, 2016, diplomsko delo/naloga
Opis: Sustainability practices and sustainable development have been in close relation with human beings for a long time. This thesis aims to present historical aspects of sustainable development throughout the time, along with numerous green business ideas and green organizations presentations. From hunter-gatherers to ancient civilizations to fossil fuel era, historical review consists of connections between people from different times and places. Whilst moving from history to the present, the thesis offers insight in terms of green and sustainability-related definitions that help in understanding the idea behind terms such as green businesses, sustainable development, eco-innovations, green products, green consumer, green marketing, greenwashing, green certification, and carbon offsets and carbon credits. For better understanding of the related theoretical approaches, the thesis also offers a wide range of green business ideas such as green building and urban planning, sustainable agriculture, renewable energy sourcing, sustainable forestry, green transportation, green hair salon, green gym, green wedding planning, green cleaning services, recycling and waste management, and sustainable brewing. The benefits, issues and risks that green businesses are dealing with are also described. Green practices nowadays are represented by many individuals and organizations, of which some are also included in the research part of this thesis. 32 organizations have been interviewed and provided valuable data that was used in creating a brand new sustainability model, called ‘Path to sustainability’, which aims to connect vital sustainability fragments together in a wholesome system, along with connections between related fragments. Besides the model, the thesis also provides an overview of issues and restrictions that oppose sustainable development.

Opis: Authorities in Slovenia and other EU member states are confronted with problems of city transportation. Fossil-fuel-based transport poses two chief problems—local and global pollution, and dwindling supplies and ever-increasing costs. An elegant solution is to gradually replace the present automobile fleet with electric vehicles (EVs). This article explores the economics and practical viability of the provision of solar electricity for the charging of EVs by installation of economical available Photovoltaic modules. A steep decline in the module, inverter and installation costs is reported herein. Present estimates indicate that for the prevailing solar climate of Celje—a medium-sized Slovenian town—the cost would be only 2 euros and 11 cents per kWh of generated solar electricity.
