Japan: Taiheiyo Cement has installed three BWZ bucket elevators and a Louise TKF drag chain conveyor supplied by the Hong Kong-based subsidiary of Aumund at its new power plant at Ofunato. The cement producer uses both biomass and coal at the plant.

Two elevators and the drag chain conveyor are used to transport palm kernel shells (PKS) and palm empty fruit bunches (EFB), which are used as alternative fuels in the power plant. Each has a capacity of up to 150t/hr. The conveying concept is designed so that the different materials are kept apart and enter the silo buffer tanks separately. The third bucket elevator is used for coal handling. It is a gravity discharge type BWZ-S elevator with a capacity of up to 35t/hr.

US: Italy-based Buzzi-Unicem subsidiary Alamo Cement Company has signed a contract with Italy-based renewable power supply expert Renergetica for the construction of a solar power plant at its 1.1Mt/yr integrated Plant 1604 cement plant in San Antonio, Texas. Renewables Now News has reported that the plant will have a capacity of 10MW.

El Salvador: Switzerland-based LafargeHolcim subsidiary Holcim El Salvador has announced that it substituted 26,000t of refuse-derived fuel at its 1.7Mt/yr integrated El Ronco cement plant in Metapán, Santa Ana department, in 2019, up by 30% year-on-year from 20,000t in 2018.

In 2019 Holcim El Salvador produced 1.2Mt of cement. The company is currently investigating the possibility of installing a US$5m solar power plant at the El Ronco cement plant. It has signalled an intention ‘in the long term’ to resume operations at its 1.6Mt/yr Maya cement plant, mothballed in 2008, at an estimated cost of US$20m.

UK: N+P says that Subcoal production will start at its Teeside plant in July 2019. Following nearly a year of de-commissioning and site preparation works. The project has achieved financial close and construction work has commenced following nearly a year of de-commissioning and site preparation works. The plant will consume 0.25Mt/yr of commercial and industrial waste feedstock and will produce 0.19Mt/yr of N+P’s Subcoal product. The engineering, procurement and construction (EPC) contractor is Fairport Engineering.

The Teeside plant will supply Subcoal pellets to different outlets including Simec Atlantis Energy (SAE) for use in its Uskmouth 220MW coal-fired power station, which is being converted from coal to waste-derived fuel. N+P and SAE have agreed a fuel-supply agreement to supply nearly 1Mt/yr to the power station once it has been converted to using Subcoal in place of coal in 2021. To meet demand for the contract, N+P plans to build a further three Subcoal plants.

UK: The Netherland’s N+P Group has started a joint venture with Simec to sells its refuse-derived fuel (RDF) pellet product Subcoal to power stations. The joint venture, Simec Subcoal Fuels (SSF), has signed a 20-year fuel supply agreement with the Uskmouth power station in South Wales, to supply 900,000t/yr tonnes of Subcoal. N+P and Simec want to build at least four new Subcoal production units in the UK to support the contract at Uskmouth.

“This joint venture with Simec is a very important milestone in our growth strategy for alternative fuels with the Fuel Supply Agreement as an excellent foundation, “ said Stijn Jennissen, commercial director of N+P Group.

Simec Group, based in Hong Kong, is an international energy, infrastructure and natural resources business. Its activities span renewable energy generation, mining, shipping and commodities trading through its key hubs in Europe, the Middle East, Asia and Australia. In 2016, Simec unveiled its plan to turn the existing 395MW Uskmouth Power Station Newport into a centre of excellence for Advanced Conversion Technologies, using biomass, waste and other sustainable energy sources.

Saudi Arabia: Al-Safwa Cement has signed a deal to use carbon ash from SEC as an alternative fuel at its cement plant. The ash will be used as an additional fuel with heavy fuel oil. Oil residues from SEC’s power plants will also be used, according to the Arab News newspaper. The agreement is expected to last seven years.

Sweden/UK: Siwertell, part of Cargotec, has signed a contract with the Spanish-Korean consortium, TR-Samsung, for a Siwertell ship unloader to support a new biomass-fuelled power plant under construction in Teeside, Middlesbrough in the UK.

"We provided extensive references demonstrating our ability to meet the owner's high standards and design criteria," said Peter Goransson, Siwertell Sales Manager & Senior Advisor. "Important factors included compliance with environmental directives, a proven track record of good reliability and safety, high through-vessel discharge rates and the ability to handle sensitive products with minimal cargo degradation or breakages."

Siwertell will deliver a customised rail-mounted ST 790-type D Siwertell unloader, which will be located close to the 299MW plant in Teesport. It will discharge wood pellets and wood chips to a matched Siwertell jetty conveyor with a movable transfer trolley, supplied as part of the contract. Siwertell biomass unloaders are also equipped with a new-generation safety system to mitigate the risks of fire and dust explosion when handling biomass in an enclosed space.

The unloader has a rated average capacity of 1200t/hr and a maximum rate of 1320t/hr, designed to meet the plant's requirements of 16,000t/day. It is equipped with a dual truck loading system for continuous direct truck loading at a rate of 300t/hr. This is a redundancy feature that allows operations to continue if the shore conveying system fails.

The unloader will be built in Europe by Siwertell's production partners and will be delivered fully assembled in 2018.
