The Creation of Refuse Derived Fuel (RDF) and Biogas through a Mechanical Biological Treatment Technology
Glen Tobiason, Quality and Environmental Management, Zweckverband Abfallbehandlung Kahlenberg
The challenge of ecological and economical treatment of household waste depends not only on the make-up of the waste but also on many other factors. Local, county, State and Federal regulations, current waste management practices, cost of ownership, reuse, recycling or disposal of outputs, knowledge of “what is available out there?”, “we have garbage as well”, partial, non complete solutions, use of best available technologies are among these. Solutions to such a challenge vary just about as much as the factors of the challenge itself!
One solution is through the implementation of the mechanical-biological treatment (MBT) process to treat household waste. This MBT process has not always been regarded as viable. A MBT process is now available as a tried and proven very adaptable and very flexible solution. MYT® or Maximum Yield Technology is such a complete method and can be designed and built to the needs, waste content and quantity, regulations, output needs etc.
A typical MYT®layout consists of the following five steps:
1. Waste acceptance
2. Mechanical Preparation
3. Biological Conversion
4. Biological Drying
5. Mechanical Material Separation
The following MYT®-design, operational and quality aspects will be presented:
1. Scalability and Flexibility
2. MSW feedstock
4. Market for output / direct thermal conversion
5. Other complementary technologies
6. Cost to Citizens
7. Costs of a MYT®plant
8. Emission matters
9. Regulatory compliance
10. Public acceptance
Glen Tobiason has received his Bachelors degree in Mechanical Engineering from Northeastern University, Boston. Mr. Tobiason has over 11 years experience in all process steps of the Maximum Yield Technology (MYT®) used at the Kahlenberg Mechanical Biological waste treatment facility. Being fluent in both English and German, he has the opportunity to introduce the benefits, flexibility, scalability and sustainability of MYT® to various countries and cultures. Additionally Mr. Tobiason is also responsible for the adherence to the governmental regulations pertaining to the plant, worker safety as well as for the logistics of Inputs (MSW etc.) to the plant and landfill and correct marketing logistics of the outputs (RDF) of the plant.
