US: RePower South has starting processing materials at its new 0.2Mt/yr waste processing plant at Moncks Corner in South Carolina. The unit uses equipment supplied by Bulk Handling Systems (BHS) as part of its BHS FIberPure process that utilises screen, air, optical and artificial intelligence (AI)-powered robotic sorters. It also uses seven NRT optical sorters and nine Max-AI Autonomous Quality Controls (AQC). The plant can process up to 50t/hr of mixed waste to produce a fuel feedstock.

The plant also produces ReEngineered Feedstock (REEF) from non-recyclable papers and plastics. This fuel product is sold to industry, cement, and utility customers to replace coal in production processes. The fuel system uses a Loesche Energy Systems RocketMill to dry, purify and size the REEF.

Egypt: Suez Cement’s Kattameya plant has started using a 10% waste-derived alternative fuels substitution rate in its main kiln burner. It brings the plant’s total thermal substitution rate up to 25%, in combination with the 15% rate of alternative fuels it already uses in the calciner. The plant’s volume of waste and biomass will double to 75,000t/yr. The subsidiary of HeidelbergCement’s plans to increase its substitution rate to 30% in the future.

UAE: Cement plants in Ras Al Khaimah are using camel dung as alternative fuel. Saif Al Ghais, director of the Environment Protection and Development Authority in Ras Al Khaimah, said that cement plants in the emirate are co-processing a mixture of camel waste, wood waste and refuse-derived fuel, according to the Khaleej Times newspaper. The emirate is also considering using cooking oil in its cement plants. The initiative is part of the country’s national recycling and sustainability strategy.

Poland: Germany’s Vecoplan has opened an office in Warsaw to support the local market. Vecoplan Polska opened its branch office in November 2018. Ireneusz Suszyna will be the local lead for domestic and commercial waste and refuse-derived fuel (RDF). Machine and service sales will be handled by the new office and technical and project support will be provided from the head office in Bad Marienberg in Germany.

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.

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.

UAE: Pioneer Cement had signed a deal with Emirates RDF to use refuse-derived fuel (RDF) at its plant in Ras Al-Khaimah. The subsidiary of Oman’s Raysut Cement says it will be one of the first cement plants in the region to use waste fuel to meet the government’s sustainability vision, according to the Al Riyadh newspaper.

Emirates RDF operates a plant at Umm Al Quwain. It is a US$40m joint venture developed under a Public Private Partnership (PPP) programme co-financed by the Ministry of Presidential Affairs with the Ministry of Climate Change and Environment signing a concession agreement with its shareholders which include the UAE-based contractor, BESIX, Ajman-based Tech Group and Finland-based Griffin Refineries. Emirates RDF will process household waste from Ajman and Umm Al Quwain in the Northern Emirates. Trial RDF production at Emirates RDF is scheduled to start in the summer of 2019 and full production is planned for early 2020.

India: The Chhattisgarh Environment Conservation Board has granted permission for the Ramki Group to build the first waste processing plant in Raipur. The project will have a budget of US$17m, according to the Times of India newspaper. Refuse-derived fuel (RDF) from the unit will be supplied to local cement companies. The unit will produce fertiliser for farmers as well. Ramki Group also plans to build a waste-to-energy plant at the site and the state government is considering a proposal.

India: The city corporation of Tirupur has signed a letter of intent to supply 30t/day of refuse-derived fuel (RDF) to ACC’s cement plant at Madukarai near Coimbatore in Tamil Nadu. The city authorities are struggling to separate waste streams generated by its residents, according to the Times of India. The authorities are trying to improve local awareness to segregate waste at source to aid reuse, recycling and disposal.
