Brazil: Votorantim Cimentos’ Salto de Pirapora integrated plant in São Paulo has recevied environmental clearance to burn municipal waste. The plant processed 17,900t of waste in 2018 during a testing phase. It has the capacity to process up to 65,000t/yr. From 2016 to 2019 it invested US$12m on upgrading the unit to accept alternative fuels. It now plans to spend US$43.5 over the next four years.

The cement producer is also running trial co-processing projects at its plants at Rio Branco do Sul in Paraná, Cuiabá in Mato Grosso, Sobral in Ceará and Brasíliain in the Distrito Federal. The company had a thermal substitution rate of around 30% in 2018 and it processed 0.85Mt of biomass, tyres and municipal waste.

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.

Russia: LafargeHolcim Russia has won a Change Management Visionary award for its co-processing activities at its Ferzikovo cement plant in Kaluga. The company says it is the only business licensed to co-process waste by the Russian government. The Geocycle operation at the unit processed around 26,000t of solid municipal waste in 2017 sourced from the Kaluga and Moscow regions. The plant processed 1000t/month of plastic packaging waste in 2017 and this is expected to rise to 2000t/month in 2018. The company says that its treatment is aligned with European Union waste treatment principles.

China: Anhui Conch’s Xing'an cement plant in Guangxi region has commissioned a municipal sold waste (MSW) project. The project was started in late 2017 and it has had investment of US$19m. It is intended to process 100,000t/yr of MSW and 49,500t/yr of sewage.

Switzerland: LafargeHolcim’s global waste management business, Geocycle, treated 10Mt of waste in 2017, an increase of 13% year-on-year from 2016. It co-processed all types of waste in cement kilns including solid shredded waste from industrial and municipal origin, spent solvents, used tires, waste oils, contaminated soils, industrial and sewage sludges, as well as demolition waste.

“At LafargeHolcim we offer solutions which facilitate the simultaneous recycling and recovery of waste. We have ambitious plans to continue investing in all parts of the world in order to bring the most advanced technology and solutions to our partners and play a role in solving the global waste problem,” said Jan Jenisch, the chief executive officer of LafargeHolcim.

In Europe and North America, the main growth area for LafargeHolcim’s global waste management business was industrial waste, while in Africa more biomass waste such as rice and coffee husks were treated. The strongest growth rates for municipal solid waste (MSW) were seen in Asia and Latin America, where waste infrastructures are still developing and municipalities continue to seek more sustainable solutions for the growing volume of household waste.

In 2017 LafargeHolcim built three new major waste treatment facilities: Kujawy in Poland, El Sokhna in Egypt and Oum Azza in Morocco. It said that Oum Azza is the first waste pre-processing platform for MSW in the Middle East and Africa.

US: RePower South, a licensee of Accordant Energy, has started building a municipal solid waste (MSW) processing plant at Moncks Corner in South Carolina. The unit will use Accordant's ReEngineered Feedstock technology to process 50t/hr of MSW to make the company’s ReEngineered Feedstock product, a type of refuse-derived fuel (RDF). ReEngineered Feedstock will be marketed to cement plants and other industrial users.

"The RPS team has decades of experience in the recycling, solid waste, energy, finance, and construction industries, having built, owned, and operated multiple recycling and solid waste companies. We are confident this first commercial facility utilising the Accordant technology will improve recycling performance and landfill diversion while providing a renewable solid fuel for cement kilns and utility and industrial boilers," said Paula A Calabrese, Senior Vice-President and Chief Strategy Officer of Accordant.

Accordant says that its ReEngineered Feedstock product can be engineered for a variety of combustion applications and is physically and chemically designed to mimic the properties of coal. The product also holds a non-waste fuel determination from the Environment Protection Agency (EPA) allowing regulatory benefits for its users.

China: FLSmidth, Sino Environment Engineering Development (SEPTEC) and China Resources Cement (CRC) have signed a partnership to provide pyroprocessing co-processing systems to cement plants. FLSmidth will be responsible for the design, engineering and integration of the integrated waste burning solution, with SEPETC acting as a general contractor.

The agreement follows a project at CRC's Hongshuihe cement plant that took municipal and industrial waste from the city of Binyang in Guangxi. FLSmidth installed a Hotdisc system that could process 300t/day of waste to support the cement plant’s cement production capacity of 3200t/day.

"China's energy intensive industries, such as cement production, are coming under pressure from the government that wants to rebalance the economy towards a less energy-hungry mode of growth, curb pollution and reduce carbon emissions. CRC plans to initiate several similar municipal solid waste co-processing projects for other cement producers with FLSmidth and SEPETC as partners," said FLSmidth China Country Manager, Cyril Leung.

In China's latest five-year plan, the government encourages more cement producers to co-process municipal solid waste in the cement industry, with an aim of getting 15 - 20% of the cement kilns in the country to be co-processing waste by 2020. In 2017, China will introduce a national carbon-trading scheme in 2017.

Oman: Al Ramooz National LLC has selected Bulk Handling Systems (BHS) to provide two mixed waste processing facilities in Oman. A 220t/day plant at Ibri and a 150t/day plant at Buraimi will treat municipal solid waste from the governorates of Al Dhahirah and Al Buraimi in northwest Oman. Both systems will be commissioned in 2017.

The new plants will process waste for French company Veolia and Al Ramooz, which were awarded a seven-year waste management contract tendered by Oman Environmental Services Holding Company in 2016. The contract includes the collection, transportation and landfilling for 250,000 residents. To fulfill this contract, Al Ramooz National LLC takes charge of collection, material processing and recovery. To maximise recovery and product quality, Al Ramooz National LLC selected BHS’ patented MSW process, combining screen, air and optical separation technologies to capture recyclable commodities and to produce alternative fuels.

“These two systems are an investment in the long-term sustainability of Oman,” said Al Ramooz Chairman Ali Saleh Al Sahib. “BHS offered the most advanced and complete system to help us reach our goals and we are especially excited to bring such a high level of technology to our process. We were able to collaborate on creative layouts to immediately maximise our recovery and value from the waste stream while simultaneously building in the flexibility to expand our processing capabilities in the future.”

The plants will feature the BHS Metering Bin Liberator Class to open bags and provide the system with a steady flow of material. BHS Tri-Disc screens will extract organics and separate containers from fibres, while Nihot Single Drum Separators will segregate dry recyclables from bulkier items, such as wood and rock. NRT’s In-Flight Sorting optical technology will target PET, HDPE, PP and PVC. Cardboard, mixed paper, ferrous metals and aluminium will also be recovered.

Belarus: The Council of Ministers of Belarus has approved the creation of a plan for the production of alternative fuels from municipal solid waste (MSW) and its use in the country. The aim is to expand the scope of use of municipal solid waste and its conversion into refuse derived fuel (RDF) including usage at cement plants.

The project aims to replace imported coal and natural gas with RDF levels of up to 330,000t for use by cement kilns. This will require around 1.1Mt of MSW or 26% of the country’s supply. In order to do this it has been recommended that new MSW sorting facilities should be set up and the existing ones should be retrofitted to produce raw materials for RDF.

The works will be implemented in two phases. Under the first phase (2016 - 2017), two facilities for the production of RDF will be set up in Krichev to supply Krichevcementnoshifer and Belarusian Cement Plant and one in Krasnoselsk for the Krasnoselskstroymaterialy company. In addition the fuel supply systems will need to be upgraded at the cement plants, production of raw material for RDF will be organised at the existing waste treatment plants in Brest, Mogilev, Gomel, Baranovichi and a waste sorting plant that is under construction in Grodno.

The cost of the first phase is estimated at Euro227m. Under the second phase (2017 - 2020), the output of raw materials for the production of RDF will be increased. In particular, inter-regional sorting plants should be built in Bobruisk, Vawkavysk, Zhlobin, Krichev, Lida, recycling plants should be built in Vitebsk and Orsha, a waste treatment plant should be reconstructed in Gomel. The cost of the second phase totals Euro118m. If this plan is implemented in full, the overall level of waste utilisation will be approximately 27% in 2020.

Mexico: Miguel Angel Mancera, the mayor of Mexico City, has inaugurated the second phase of Iztapalapa II municipal solid waste (MSW) plant. The site will process 400t/day of MSW. Once processed the refuse-derived fuel (RDF) will be used by Cemex for co-processing in its cement plant kilns.
