Ireland: Irish Cement has been granted planning permission by An Bord Pleanala for its plans to burn tyres and tyres and solid recovered waste at its Limerick plant. Local councils originally approved the project in 2017 but this was appealed to the national An Bord Pleanala following local protests. Environmental groups say they will continue to fight the plan.

UK: Saxlund Group will present a number of case studies covering its experiences supplying alternative fuels and bulk handling systems for cement plants in Europe at the upcoming Global CemFuels Conference taking place in Berlin. Its references include a complete end-to-end solution for one of the UK’s largest cement kilns, incorporating the reception, storage, transportation, screening, weighing and pneumatic injection of solid recovered fuel (SRF). Other project experience includes secondary fuel-handling solutions for CBR Cement in Belgium, plus a refuse-derived fuel (RDF) facility for LafargeHolcim at the company’s plant in Höver, Germany. The company will also be explaining some of the issues encountered when handling modern alternative fuels and how to ensure full plant availability with minimal downtime.

The company will also be explaining its design approach for minimising storage and transfer issues for what can be sticky and challenging materials, including SRF, RDF and other biomass fuels. A key focus will be on activated silo discharge solutions and conveying equipment with an emphasis on ‘First in, first out’ design principles to minimise compaction and material conglomeration. Key technologies covered will include the company’s leading Push Floor and Sliding Frame solutions, bucket elevators and enclosed chain conveyors, plus integrated screening, weighing and dosing solutions.

US: RePower South (RPS) has started building the Berkeley County Recycling and Recovery Facility, a mixed waste processing plant. The turnkey recovery system will be provided by Bulk Handling Systems (BHS) under an engineering procurement and construction (EPC) agreement with Barnhill Contracting Company. When production begins in early 2019, the Moncks Corner, South Carolina plant will process 50t/hr of mixed waste sourced from Berkeley County to recover recycled commodities and a fuel feedstock.

The plant will use a BHS FiberPure system, consisting of BHS screens, NRT optical sorters and Max-AI autonomous quality control units to remove unwanted fractions to produce an end product with minimal manual sorting. Non-recyclable fibres and plastics destined for fuel will undergo further filtering by NRT SpydIR optical sorters equipped with MetalDirector options to remove unwanted contaminants. Max-AI AQCs are also utilised in each sorting position on the container line. In total, the system will use seven NRT optical sorters and nine Max-AI AQCs. In addition, Loesche Energy Systems will provide a Loesche RocketMill for size reduction. The system will also features two Kadant PAAL balers.

Japan: Austria’s Untha has agreed a new distribution partnership with Yokohama-based engineering firm Sun Earth. The deal will see Untha’s manufactured shredding technology supplied to a number of waste and alternative fuel production facilities throughout Japan. The agreement was arranged to help Sun Earth cope with demand for a shredding system that can tackle complex production waste, including single-step solid recovered fuel (SRF) manufacturing. Talks between the companies started in mid-2017.

Sun Earth has already placed an order for an Untha XR3000C shredder scheduled for shipment in early 2018.

India: The city corporation of Thiruvananthapuram in Kerala has finalised its proposal to supply solid recovered fuel (SRF) to the local cement industry. Two companies in Tamil Nadu have expressed interest in the project, according to the Times of India.

UK: Andusia Recovered Fuels says it is moving into the solid recovered fuel (SRF) market following its experience of the refuse derived fuel (RDF) business over the last five years. In this time the waste management company has exported over 0.9Mt of RDF.

“Despite recent claims that the RDF market is beginning to plateau, here at Andusia we are yet to notice that,” said General Manager, Mark Terrell. “The RDF export market will always be a key area for us, however we are now turning our attentions to not only the emerging UK Energy from Waste market but also to SRF exports across Europe.”

Cyprus: N+P International has extended its solid recovered fuel (SRF) supply agreement with Vassiliko Cement to the end of 2020. The deal also includes an option to further extend the agreement to the end of 2022. N+P has been supplying Vassiliko Cement with SRF from the UK and Italy by sea since 2015.

“This contract is the foundation of a long-term cooperation between Vassiliko Cement, Enerco Energy Recovery and N+P. The parties intend to maximise alternative fuel consumption in the Vassiliko Cement plant, to do so parties recently carried out a trial to co-grind N+P’s Subcoal pellets in the plants coal mills. The first results of this trial are looking very promising and further trials will be done the near future. We agreed not to disclose precise contract volumes, but at present >2500t/week of SRF is shipped into Vassiliko Cement,” said a representative of N+P.

Vassiliko Cement plans to reach a 55% substitution rate of alternative fuels by 2020.

Nigeria: Lafarge Africa has raised its capacity to use alternative fuels at its Ewekoro 1 cement plant to a substitution rate of 50%. Its Sagamu plant has the capacity to operate a substitution rate of up to 25%. Its alternative fuels sources include locally sourced palm kernel shells, woodchips, tyres and refuse. It is unclear whether or not the plants will be able to make use of this capacity in the near term.

“Our energy optimisation plan has proved successful with increased use of alternative fuel to offset gas shortages. Ewekoro 1 plant migrated from 100% reliance on gas and low pour fuel oil (LPFO) to about 40% use of alternative fuels at the plant,” said Michel Puchercos, the chief executive officer of Lafarge Africa in the group’s results for the fourth quarter of 2016.

The subsidiary of LafargeHolcim plans to use alternative fuels at all of its Nigerian cement plants by 2018. Ewekoro 2 will be utilising alternative fuels, Ashaka will be using alternative fuels and coal and Mfamosing is expected to be using petcoke and alternative fuels.

Namibia: Environment minister Pohamba Shifeta has inaugurated Namibia’s first solid recovered waste plant in Windhoek. The US$15.7m unit is a joint-venture between local company Rent-A-Drum and Ohorongo Cement, a subsidiary of Germany’s Schwenk Zement, according to the Xinhua News Agency. Rent-A-Drum will collect more than 12,000t of non-recyclable waste material that will be converted into alternative fuel for use by Ohorongo Cement. The waste plant has created 60 jobs.

Ireland: Limerick City and County Council has given permission for Irish Cement to co-process alternative fuels at its local cement plant. Permission has been granted subject to 16 conditions, according to the Limerick Leader newspaper. The cement producer has been seeking a licence to use solid recovered waste and tyres at its plant but it has faced local opposition.
