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.

New Zealand: Fletcher Building has ordered a Hotdisk Combustion device from Denmark’s FLSmidth for installation at its Golden Bay Cement plant in Portland. Once the Hotdisk is operational the plant’s kiln will consume up to 3.1 million shredded tyres per year. Carsten Damslund Jensen, Global Product Line Manager at FLSmidth, said that the company is forecasting the sale of 10 Hotdisk units in 2019. Demand around the world, and especially in China, is driving the growth.

Spain: Geocycle Spain’s Albox plant’s production of alternative fuels rose by 20% year-on-year to 53,000t of in 2018 from 49,000t in 2017. The company said it had invested Euro0.86m towards innovation in the business in 2018, including a new waste treatment line, according to the Ideal newspaper.

China: Jidong Cement Fengxiang plant in Tianjiazhuang district in Shaanxi is holding a public consultation before it disposes of 0.1Mt of hazardous waste. The cement company plans to process the waste in its 4500t/day kiln. It says that it can meet environmental regulations during the operation

India: Local government bodies in Chennai in Tamil Nadu have complained of the cost of sending plastics waste to cement plants. Five municipalities are spending of US$40,000/month on transport costs, according to the New Indian Express. Since 2017, 54 local government bodies have sent waste to cement plants for co-processing. Of these, 49 local bodies send it to UltraTech Cement’s plant at Ariyalur. However, the plant only pays transport costs for the waste sourced within a 100km radius. The state is looking into supplying plastics waste to nearer buyers.

Spain: Cemex has signed a Euro117m deal with the local government to convert the land used by the Gádor cement plant in Almeria for use by new projects. These will include projects in solar and wind power generation, waste fuel production from plastics and biomass and a new concrete batching plant, according to Teleprensa. The initiative is intended to create around 400 jobs.

The cement producer has also signed a similar agreement for its Lloseta in Baleares. The company announced in mid-October 2018 that it was planning to close the two plants due to reduced demand for cement and mounting European CO₂ emissions regulations.

US: LafargeHolcim’s Ravena cement plant in New York is considering burning tyres as an alternative fuel. Environmental Director Kevin G Bretz told Coeymans town officials that the cement producer has ‘developed relationships’ and held ‘preliminary discussions’ with potential tyre suppliers, according to the Times Union newspaper. The cement producer was hoping to use an approval by the state Department of Environmental Conservation granted in 2006 that gave permission for it to burn up to 4.8 million tyres annually at the plant. However, this Beneficial Use Determination (BUD) expired in mid-2018.

Brazil: Votorantim Cimentos has won an award for its açaí stone co-processing project at its Primavera plant in Pará state. It won the atmosphere emissions category at the 14th Brazilian Environmental Awards organised by the American Chamber of Commerce for Brazil. The plant processes 6500t/month of açaí berry stones and it plans to target 10,000t/month. The state of Pará produces around 0.5Mt/yr of açaí stone.

Namibia: Ohorongo Cement’s plant at Walvis Bay has had an alternative fuels substitution rate of 40% for the last six months of 2018. Local recycling company Rent-A-Drum said that it has been supplying waste fuels to the plant, according to the Namibia Economist newspaper. As well as fuels from domestic waste the plant is using wood chips and charcoal dust in its kiln.

China: Guangzhou Zhujiang Cement has completed a dry sludge co-processing project at its plant in Shenxian, Baiyun in Guangdong. The plant can process 300t/day of the dry sludge. CNBM Sinoma’s subsidiary Tianjin Cement Industry Design & Research Institute (TCDRI) was the main contractor on the initiative. The project was agreed in early 2016, built in 2017 and then tested from late 2017.
