Biogas is produced during the process of anaerobic digestion of organic waste. It is an important element of the purpose to minimize the dependence of natural gas, as well as to contribute to less pollution of the environment. The best way to achieve such goals, is to utilize every organic waste and produce valuable product. Alcoholic industry is a large sector and produces huge amounts of alcoholic beverages. Like any other food industry, there are organic wastes during and after the production process. One such organic waste is the stillage. It is a liquid waste material, produced after distillation. Stillage contains various nutrition elements, which could be used as feeding material for biogas production. As it is a way to utilize organic waste, there is a scientific interest to research the possibility to utilize it in an anaerobic digestion bioreactor to produce biogas. For that purpose, the stillage is mixed with cattle manure. The accumulated biogas could be used for heating, auxiliary electrical power (powering CNG generators) and as an alternative fuel for vehicles.

Humanity enters Industry 4.0. It is characterized by the emergence of numerous innovative technologies that should be produced in “smart” factories. However, this presents the entire Western world with a problem. Talking about the industry for machines, we immediately talk about machine engineers who power this industry. However, in the West, the crisis with this type of personnel is severe because of our previous ideology – “Knowledge Economy” which diverted many of the finest young people towards social science specialties and above all, those related to economics and management. Therefore, the West, is tasked with creating a new quality industry for machines without the engineering personnel to secure this process.This report presents a new approach to bring back the previous and well-deserved prestige of the all-important engineering profession through a fourth and final engineering wave in the development of a holistic business model ontology, a wave that will also generate a new quality of systemic economic engineers – the necessary engineering capital for realizing Industry 4.0.
