Talk to someone not in the waste industry and you'll find they're stunned that in 2019, we're still burning and burying waste, or even just allowing it to rot on the forest or orchard floor, or on the farmer's field. These methods result in losing the valuable energy found in waste - energy which can both help to relieve the pressure on rapidly diminishing fossil fuels and help reverse the harmful trends of global warming and climate change. Climate change is no longer a problem for the next generation. We simply must do better and do better now.
Eggersmann sells innovative drying system for RDF to Iraq along with the world's largest turner
Backhus turner key to alternative fuel (RDF) system processing 1,040 tonnes per day of MSW and commercial waste
A newly developed system by Eggersmann for drying of Municipal Solid Waste is being put into service for the first time at a Mechanical- Biological Waste Treatment plant (MBT) in Iraq. Contracts were signed with the client, the Faruk Group, in December 2018 at Suleymaniyah, Iraq.
The Faruk Group is currently constructing a mechanical-biological waste treatment plant at Suleymaniyah for the production of alternative fuel (RDF) from 1,040 tonnes per day of MSW and commercial waste. The RDF produced will be used in the group's own cement plant. This large-scale project also includes a sanitary landfill with leachate collection for the processing residues. Faruk assigned the Eggersmann Group with the planning, supply and commissioning of the biological drying process phase. The deciding criteria were mainly the process reliability and the commercial efficiency. The scope of supply also includes a stationary primary shredder.
With this latest development of its proven technologies and components for biological drying and composting, Eggersmann is bringing the treatment of organic waste and MSW to a new level. The innovative BACKHUS CON system is a combination of the membrane-covered CONVAERO process and the self-propelled BACKHUS turner. With moderate invest cost the site operation is cost efficient and low on emissions, according to Eggersmann.
22 drying lanes with aeration and membrane cover are being built on 40,000 m² of land at Suleymaniyah, northern Iraq. Each lane has a capacity of 2,600 m3 MSW and will be fitted with aeration and process control. The BACKHUS CON 100 is the world's largest turner with an effective operation width of 10.0 m and a total width of 14.5 m. It is fitted with tracks to run along the outside of the lane walls, while the waste will be turned within the lanes.
In addition, the BACKHUS CON is equipped with two membrane cover winders to simultaneously winding and unwinding membrane covers during turning. Since the system is effectively closed during turning, this method is particularly suitable for sites where emissions are a critical issue. A further advantage of the system is the short processing time. Even materials with a high moisture level and high density can be efficiently composted or dried.
At the front end of the treatment process at the Suleymaniyah MBT, an Eggersmann single-shaft TEUTON ZS 55 shredder ensures continuous shredding and a uniform discharge of shredded waste to the conveyor systems towards the drying area. One TEUTON ZS 55 in two-shift operation is sufficient to cover the sites' daily throughput.
The plant is designed for an annual throughput capacity of 380,000 tonnes. The plant will be in operation seven days a week with two operation shifts and one cleaning and maintenance shift per day.
The ground works at Suleymaniyah are already well under way, installation of aeration system for the drying lanes is scheduled to begin in May. The delivery of the other components and machines is planned to start in June, the warm commissioning is expected to start at the end of the year.

While most digestate produced by on-farm anaerobic digestion (AD) plants in the United States is separated into liquid and solid fractions, further treatment before application to land or sale for use as a soil conditioner is usually limited to composting the dry fraction. However, in Europe pasteurization is commonly used as part of the AD process to allow digestate produced from foodstuff or animal by-products to be used or sold as a fertilizer and soil improver. Some farm plant owners also pasteurize their feedstock or digestate in order to reduce the risk of plant pathogens and weed seeds carrying through in the digestate.
