Tiivistelmä
This thesis focuses on the production of biogas obtained from the food industry. The main idea of the work was to present anaerobic digestion process for food industry and having co-operation with the factory of frozen French fries, Farm Frites Poland SA, where the existing Wastewater Treatment Plant was developed by implementation of biogas plant.
Thesis introduces the proper management of food wastes and losses, and their utilization. This installation and technology brings a lot of benefits such as: recovery of electricity and heat by the CHP units, lower operating costs and, of course, reducing greenhouse gases emissions.
In chapter 2 the main concepts of the thesis and their explanation are presented. The next section contains information about biogas; what it is, its potential as well as its advantages and disadvantages. Chapter 4 presents different branches of the food industry where the anaerobic stage may be successfully implemented and their legal framework. In chapter 5 the focus is on the production of biogas during the anaerobic process; its feedstock, process biology and technology and also possibilities of use. The last chapter is a presentation of a real, implemented biogas plant in Farm Frites Poland SA, which has improved the process of wastewater treatment and allowed recovery of electricity and heat for the need of factory. Presented are laboratory analysis and comparison of post-production wastewater with finally purified effluent.
