Defining the best process for a Mechanical-Biological Treatment Plant

Before outlining a Mechanical-Biological Treatment (MBT) or Mechanical-Biological Pretreatment (MBP) process, we should take a look at 3 points that are essential to the success of a plant project.

- Firstly, we will see why we need to have good knowledge of the composition of the source Household Waste (HW).
- Then, we will mention the new trend of favouring recovery of recyclables.
- Finally, we will show the advantages of sorting prior to pre-fermentation.
After looking at these 3 points, we will see, in simple terms, which objectives are decisive when choosing the treatment method.

Finally, we propose an MBT process enabling you to achieve the set objectives, and the possible adaptations for changing or upgrading it.

1 The essential points
1.1 Composition of the collected refuse
1.2 Favouring recovery of recyclables
1.3 Advantage of sorting prior to pre-fermentation
1.3.1 Limiting the pollution of the source HW
1.3.2 Optimising the size of the plant
2 Objectives of the MBT plant
2.1 Producing compost
2.2 Stabilisation by composting
2.3 Producing energy
2.4 Recovering recyclable materials
3 Standard process proposal
3.1 1st Process: 2 modules
3.2 2nd process: 3 modules
3.3 3rd process: 4 modules

Wertstoffhof 2020 - Neuorientierung von Wertstoffhöfen
© ia GmbH - Wissensmanagement und Ingenieurleistungen (4/2015)
Im Jahr 2014, zwanzig Jahre nach dem durch das Bayerische Staatsministerium für Landesentwicklung und Umweltfragen organisierten Wettbewerb „Der vorbildliche Wertstoffhof“, ist es sicher angebracht, sich dem Thema erneut zuzuwenden. Was ist aus den prämierten Wertstoffhöfen der Preisträger in den jeweiligen Clustern geworden? Wie hat sich das System grundsätzlich entwickelt? Wo geht es hin, wenn man die gesellschaftlichen Anforderungen aus demografischer Entwicklung, Ressourcenschutz und Klimarelevanz betrachtet?

Simulation of biological plants working with municipal solid waste
© Wasteconsult International (6/2009)
To build mechanical biological plants, municipalities and engineer departments need tools to compare different proposals. The methodology to test a plant aims knowing the flow sheet of each stream in the composting or anaerobic digestion plant, quantifying the weight of refuses, gas losses, stabilised waste and compost. With a universal model of matter we can establish the material balance for dry matter, organic matter, and various categories of MSW. With a library of equipment tools and various kinds of waste, many simulations become possible in fictive plants. The validation of the simulation software has been successfully tested after the plant building. The first software was developed under excel but today, it has been improved through a special application of Ecoval, named Compowaste. Keywords: MBT, MSW, Municipal Solid Waste, Simulation, Compost, Composting, Impurities. 1 Introduction 2 Methodology 2.1 Sampling 2.2 The model of matter 2.2.1 Drying 2.2.2 Sieving 2.2.3 Sorting 2.3 Precision 2.4 Material balance 3 Simulation 3.1 The library of tools 3.2 The input 3.3 The graph drawing 3.4 Modifications 3.5 Calculations 4 Uses 4.1 Material balance in composting plants 4.2 The economic point of view 4.3 The waste management 4.4 Users 5 Conclusion

Results of comparative studies of various European parameters for determining degree of biological stabilization
© Wasteconsult International (6/2009)
Base for the comparison of various European parameters for determination of biological stability degree of products of biological treatment of residual waste, were investigations conducted on different plants for biological treatment in Europe. Samples of the input material, of intermediate products and the output material were taken and the following parameters were investigated: BM100, SRI, DR4, ASTM, PDRI. The results of laboratory tests were statistically evaluated to find out correlations between the differentparameters. Keywords: Municipal solid waste, mechanical-biological treatment, MBT, biological stabilisation, SRI 1 Introduction 2 Stability tests 3 Correlation calculations 4 Tested MBT plants and sampling 4.1 Overview of tested MBT plants 4.2 Sampling 5 Results of correlation tests

Recyclable materials recovery after biological treatment of the residual fraction: quality improvement and contribution to landfill diversion targets
© Wasteconsult International (6/2009)
Even in districts where source separated collections are implemented, a Residual Fraction remains. This fraction can be treated in MBT (Mechanical Biological Treatment) Plants that, other than stabilising biologically the waste, can produce a fuel and other recyclable fractions. Further materials recovery for recycling purpose is possible: the critical point is the quality of the materials that should be recycled. Results of experimental and industrial experiences of simple materials recovery techniques applied to residual waste in different plants where the residual fraction has been submitted to aerobic biodrying process are presented. Keywords: MBT, Biodrying, recycling, residual fraction 1 Introduction 2 Trials and Data Collection 3 Discussion 4 Conclusion

THERMISCHE VERWERTUNG VON ERSATZBRENNSTOFFEN IN DER ZIRKULIERENDEN WIRBELSCHICHT
© Saxonia Standortentwicklungs- und -verwaltungsgesellschaft mbH Freiberg (9/2005)
In vielen europäischen Staaten sind bzw. werden bald neue Deponiebestimmungen wirksam, nach denen zu deponierende Materialien verschärfte Kriterien erfüllen müssen, etwa hinsichtlich eines maximalen Heizwerts bzw. eines maximalen Restkohlenstoffgehalts.
