Biological resources such as bio waste are considered as a potential source that can provide value to the economy and contributes positively to climate change and protection of resources. This requires the implementation of a separate collection of bio-resources and further treatment with its material and energy recovery paths respectively anaerobic digestion followed by composting the digestate.
This is the concept of a circular economy (CE) which covers source separation, collection and transportation, material recovery, treatment and resource recovery and final disposal.
The HOOU course “Biological Waste Treatment” aims to impart knowledge concerning the realization of circular economy by planning a biological waste treatment facility. All participants with engineering background are able to develop and explain the design and layout of anaerobic and aerobic waste treatment, describe different techniques for the gas and bio-waste treatment.
The main goal of this course is to plan a biological waste treatment facility for the fictitious city “Biocity”. The simulation is carried out within different working groups, which represent a certain consultancy company, different climates and different political and social environments. Overall, each project has to fulfil the following requirements:
- Support a Circular Economy by Zero Waste Strategy
- Provide an innovative concept for biological waste treatment following State of the Art Technology
- Ensure minimum environmental impact by emissions and residues;
- Guarantee a competitive advantage through cost reductions and improved efficiencies.
As a part of the project the online tool “Learn2compost” was developed for education and training of students and public authorities to plan composting facilities. It consists of two parts which allow choosing different substrates from the data base in order to ensure the optimum process conditions, and on the other hand, selecting a suitable type of system.
