Ahead of Our Time:

The Jumbo Group smart dry GmbH

Manufactured in Buttenweisen, Germany.
The highest quality and most efficient sludge drying and pelletizing systems on the planet. With the experience of hundreds of installations in Europe, it’s now “OUR TIME” in North America.

We are in the midst of ever increasing pressure to expand the treatment of sewerage sludge and Biomass Sludge. The European community is 6-10 years ahead of us in dealing with these exact pressures.

The game changer is the ability to transform sewerage sludge and biomass disposal problems into a Product!

It is not rocket science. Just physics, the right technology, and a bit of common sense!

We will eventually follow the exact same path as the Europeans:

  • No more wet sludge to be spread on fields due to eventual “run-offs” into our lakes and streams.
  • 90% Dry Pellets are Produced
  • No Dust Emissions
  • No Storage Issues
  • No Wasted Resources
  • Recover the Nutrients: phosphorous, nitrogen, potassium, and sulfur.
  • Low Energy Consumption.

Our STR exhaust gas dryer for sewage sludge and biomass not only fulfils all the demands of the regulations, it also goes far beyond. Due to the special geometry, drying occurs with a level of efficiency not yet achieved on the market.

The dryer uses the pure exhaust gas flow of a CHP and therefore a source of energy, which is otherwise emitted unused into the atmosphere. 50% of the thermal energy of a CHP can be found in the pure exhaust gas flow. With the 550 degrees Celcius (1022 degrees Fahrenheit ) hot exhaust gases, the dryer acheives and evaporation of 600W per liter of water, which is an unparalleled efficiency. Due to the hot air effect, complete sanitization of the dried sludge occurs in the same way as the water, which evaporates. Sludge can also be treated and dried emission free using pure exhaust gas. From a tonne of contaminated sewage sludge, the exhaust gas dryer created 250kg (550lbs) of sanitized biomass, from which the nutrients can be reclaimed and fed back into a circular economy.

Using the gear pelletizer, which was especially developed for our process, the treatment of dried sludge is dust free and emission free, forming the ideal basis for any subsequent recycling. In most cases the pellets pass Class A criteria.
