3-Day Study Tour

Biogas Advanced Training and Study Tour on Waste Processing, Pretreatment and Depackaging
South and Southwest Germany

Language: ENGLISH


It’s true!

Biogas plants that are digesting biowaste and food waste all have unique technologies… and there is no one-size-fits-all solution.

That means the equipment needs to be customized to the specific substrates and local conditions for every biogas plant.

Sure, the technology works – but it requires a lot of upfront research and testing BEFORE ordering or settling on a specific plant design.

And: once you settle on a technology and plant design, you’ll still spend multiple months, sometimes up to a year on testing, tweaking, adapting your process…

In short: selecting the best waste treatment technology for a biogas project can be a giant headache.

And we want to help you with that.

So if you’re planning to invest multiple millions  into a new biogas plant that will treat biowaste, restaurant and kitchen waste, or industrial food waste…

Or if you’re currently operating a biogas plant that’s mainly digesting biowaste, food waste, or kitchen waste…

And you keep running into biological or technological issues…

This biogas plant study tour is for you!

Before anything, you need to know that what you’re investing in will actually work.

I’ve seen many giant biogas plants that were built without doing the proper upfront work and these turned out to be giant failures.

If you plan to build an expensive biogas plant that works efficiently, so you can hit the ground running, you need to do the necessary groundwork before.

And that’s exactly why we’ve put together the program for this study tour.

In 3 days, you and a small group of like-minded biogas enthusiasts will visit 6 different biogas plants that are treating biowaste, supermarket waste and food waste in South and West Germany.

You’ll discover all the different technologies that are working RIGHT NOW – and many of them have been optimized for years.

If you’re a project manager looking to invest into a new biogas plant…

Or you want to upgrade an existing biogas plant with the most effective waste treatment technology…

This is the type of guidance that will make it extremely easy for you to understand the technology better and make a very clear decision.

My name is Michael Köttner, and I’m the CEO of IBBK.

I’ve been conducting specialized biogas study tours for more than a decade and I’m a biogas professional for almost 30 years.

Turning organic waste into valuable energy has fascinated me for a long time. And I’d like you to benefit from the experience I’ve collected since the late 1980s.

Showcasing substrates / technology explanation

I have assisted many of the biogas plants that we’ll visit in the construction phase and can give you a lot of context on their development.

In almost 30 years in this industry, I’ve witnessed many, many projects fail miserably AFTER construction due to poor, insufficient planning.

You always need to do the proper research upfront… so you’re prepared, and everything is clear before the first shovel of dirt is moved.

That’s why I’m inviting you to join me on this 3-day biogas study tour through Southern and South-West Germany.

So if you’re looking for raw, real, and honest insights into the “heart and soul” of the most successful biogas plants, this tour is perfect for you.

If you booked us to put together a tour for you, this would cost more than 10,000 € to research, prepare the material and conduct this tour. And multiple organizations have happily invested this amount. They know that for a multi-million euro investment, it’s important to know the right technology and how to use it from the start.

But: don’t worry – this won’t cost you nearly that much.

In fact, the price for this study tour is about a quarter of that.

Participation fee:

Early Bird Rate for registration & payment until June 8th: 2,500 € + VAT

(Regular Rate: 2,900 € + VAT)

Discount for more than two participants from one company or organization available upon request. Please get in touch with us under contact@ibbk-biogas.com

That means if you register until June 8th, you’ll save 400 € as an early bird (registration and payment received).

Your participation fee includes:

  • Transportation
  • 3 nights in a local hotel
  • All meals and beverages during these 3 days

You will visit 6 biogas plants that process and digest biowaste, kitchen and household waste as well as industrial food waste – all with completely different processing technologies.

You’ll get proper hands-on experience and can discover which specific technology makes sense for you, based on your local feedstocks and conditions.

Overnight, you’ll stay in local hotels, together with all other participants and myself. This way, you’ll get full “biogas immersion” with other biogas enthusiasts and professionals.

Also, we’ll include cultural aspects into the program so you get to see more than just the biogas aspect of South and South-West Germany.

This tour will take 3 full days and we recommend you arrive one day before the start so we can leave nice and early to the first plant.

Study Tour Date: July 7th-9th, 2020

Now, we’re aware of global travel restrictions due to the COVID-19 pandemic. And this date, July 7th-9th might fall into a time where the lockdown could still be in full force in some regions of the world.

However, we do NOT expect this. And we’re very confident that we’ll reach a sufficient level of normalcy again by that date to conduct this special, in-depth tour.

So here’s what you’ll experience:

You’ll visit 6 hand-picked biogas plants located in the area around Stuttgart, the greater Munich-area and around Fulda and Frankfurt.

On the first day, we’ll leave early in the morning from Stuttgart Airport to head to the first biogas plant. Meeting time is 8:30 AM at Stuttgart Airport. The nearest international airport for the start of the tour is Stuttgart Airport and there is a good train connection from Frankfurt Airport to Stuttgart Airport.

The tour ends July 9th at around 5 pm at Frankfurt Airport. At Frankfurt Airport, there is a great connection to short and long distance trains as well as international flights.

If you need to get off at a different location, please let us know and we’ll find a solution.

All 3 tour days will be filled with biogas plant visits, traveling, eating, and cultural aspects. To reserve yourself one of the handful of seats for this tour, click the orange button below.

(**Subject to change)

During the visits, you’ll experience dry and wet digestion technologies, different types of digesters, and multiple unique pre-treatment technologies.

You’ll also get a first-hand feeling for the treatment technologies developed by  established companies such as Schraden, Wackerbauer, Finsterwalder, Putzmeister, etc.

Some of the technologies have been assembled and improved by the operators themselves through years of trial and error. Some will be straight out of the catalogue.

But: they all WORK

The only challenge for you is to identify the proper configuration and find out which one optimally processes your substrates according to your needs.

These different biogas plants are diverse – but they all process one of these 3 substrates:

Municipal biowaste

Restaurant and kitchen waste

Packed industrial food waste

The throughput of the biogas plants you will see range from 5,000 t/a to 50,000 t/a. You’ll also experience a biogas plant that upgrades biogas to biomethane to inject it into the natural gas grid.

To make sure there’s always enough time for you to ask your questions and get to see everything (without having to wait for your turn), we’ll keep the group size deliberately small. That means the maximum number of participants is 5.

We’ll also take care of all logistical details during these 3 days. That means you don’t need to bring your own car, worry about finding a hotel or a restaurant.

You only need to register and show up at Stuttgart Airport on July 7th in the morning.

As you will learn during this tour, a biogas plant and its technologies are not a fixed system… but a living, breathing organism that needs constant attention and has to be adapted to every situation.

That means even if you already know which technology you’re planning use in your plant, you still have to dedicate a lot of time and effort to the perfect calibration of your plant. And visiting biogas plants that have already gone through this long and often expensive “trial and error” phase will cut your learning curve.

After each day’s plant visits, we’ll head to a nice hotel where a place to dine and a single room is waiting for you. All restaurants will have a vegetarian or vegan option.
