Development of an innovative, compact system that combines biological treatment technologies for the sustainable and environmental management of organic waste streams that are produced from different types of food processing industries

Project-Objectives

The main objective of the 'FOODINBIO' project is to develop an innovative system which will combine different biological treatment technologies for the co-treatment of organic waste generated by various food and beverages industries. The aim of the development and the demonstrative operation of this system is to present the viability of an alternative treatment technology for the effective and efficient management of organic waste generated from the food processing 'raw materials' to produce food and drinks. It is in the scope of the present project to propose a sustainable and environmentally sound solution for the management of organic waste produced from different types of food and other industries as well as to investigate in depth the possibility of utilizing the produced quantities to produce end products with high added value.

At the moment organic waste management from food and drink processing industries is very limited. Specifically, the amount of organic waste generated from food industries, are managed under conventional disposal (primarily landfill) in the majority of similar cases. The use of alternative treatment technologies is mostly limited to wastewater treatment (biological treatment with extended aeration) while for solid waste composting has been applied in little cases. In this context, the combination of biological treatment technologies for organic waste management is a new and innovative approach both European and Greek level.

 

 

 

The research objectives and expected results of the 'FOODINBIO' project are focused on the system development, and on the study of qualitative and quantitative characteristics of the final products. In particular, regarding the application of membrane bioreactors for the management of the liquid fraction of organic waste, the impact of operational parameters to the qualitative and quantitative characteristics of the produced water, as well as physical, chemical and biological properties of sludge (byproduct of the biological treatment) will be investigated. Thereafter, during the application of anaerobic digestion the production of biogas related to different operational conditions and different type of organic waste will be explored. The main focus will be the optimization of the parameters in order to maximize biogas generation. Moreover, the possibility of covering inductive energy self-consumption of the food industry from the produced biogas will be studied. The physical, chemical and biological characteristics of the liquid and solid fraction of the residue, as a byproduct of the anaerobic digestion unit will be closely monitored. Finally, through the application of the aerobic bioreactor the qualitative and quantitative characteristics of compost produced in conjunction with operating control parameters of aerobic degradation processes will take place.

 

 

The social benefits arising from the development of the system are closely related to the to achievement of environmentally sound and sustainable waste, removing the drawbacks of workload management through conventional disposal (and ground pollution groundwater through landfill, etc.).

The economic benefits are directly related to the food industries and include both financial savings related to waste disposal fees, as well as, profits from the finished products with high added value (water, electricity, and fertilizer) with potential for use in a wide range of applications.

 

 

 

Regarding the research objectives and results of the proposed 'FOODINBIO', so they focus on system development, and the study of qualitative and quantitative parameters of final products. In particular, regarding the application of membrane bioreactors for the management of the liquid fraction of organic waste, will explore the functional parameters of combined qualitative and quantitative characteristics of the produced water, as well as physical, chemical and biological properties of sludge (byproduct biological treatment). Specifically, as to the quantities of treated water produced will investigate the induction affordability of water requirements during the production process of a food industry. Thereafter, the application of anaerobic digestion unit, it will explore the potential biogas in different conditions and type of organic waste, while optimizing the parameters to maximize this potential. Moreover, in the use of biogas to produce electricity and thermal energy, will explore the possibility of covering inductive energy self-consumption of the food industry from the produced biogas. Then, we will examine the physical, chemical and biological characteristics of the liquid and solid fraction of the residue, as a byproduct of the anaerobic digestion unit. Finally, the application of the aerobic bioreactor will study the qualitative and quantitative characteristics of compost produced in conjunction with operating control parameters of aerobic degradation processes.
