Iraq: Germany’s Eggersmann Group has sold a drying system for municipal solid waste (MSW) to Faruk Group for use in a mechanical-biological waste treatment plant (MBT) being built at Suleymaniyah. 1040t/day of refuse-derived fuel (RDF) will be produced at the plant from MSW and commercial waste. Faruk Group intends to use the RDF at its cement plant.
The MBT plant includes 22 drying lanes with aeration and membrane cover. It is being built on a 40,000m2 plot of land. Each lane has a capacity of 2600m3 MSW and will be fitted with aeration and process control. The project also includes a sanitary landfill with leachate collection for the processing residues.
Faruk Group assigned Eggersmann Group with the planning, supply and commissioning of the biological drying process phase. Eggersmann will use its Backhus Con system using a combination of the membrane-covered Convaero process and the self-propelled Backhus turner.
Eggersmann says that the Backhus Con 100 is the world's largest turner with an effective operation width of 10m and a total width of 14.5m. 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 wind and unwind membrane covers during turning. Since the system is effectively closed during turning, this method is 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 will allow 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 site’s daily throughput.
The plant is designed for a throughput capacity of 380,000tyr. 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 being built and installation of aeration system for the drying lanes is scheduled to begin in May 2019. The delivery of the other components and machines is planned to start in June 2019 and the warm commissioning is expected to start at the end of 2019.
Bulgaria: Holcim Bulgaria’s Bell Ivor cement plant will increase its co-processing rate of municipal solid waste to 100,000t/yr in 2018. The plant has purchased new equipment to increase its waste processing capacity and enable it to co-process bigger municipal solid waste volumes. Geocycle Bulgaria, a waste management subsidiary of LafargeHolcim, and the cement plant source waste from a mechanical biological treatment (MBT) plant near Sofia.
