Keppel-led consortium secures S$1.5 billion contract to develop Singapore’s Tuas Nexus Integrated Waste Management Facility (IWMF)

A Keppel-led consortium has received the Letter of Acceptance from the National Environment Agency (NEA) for an Engineering, Procurement and Construction (EPC) contract worth approximately S$1.5 billion, for the development of a Waste-To-Energy (WTE) facility and a Materials Recovery Facility (MRF) for Singapore’s new Tuas Nexus IWMF.1

The consortium comprising Keppel Seghers Engineering Singapore Pte Ltd (Keppel Seghers), the environmental engineering arm of Keppel Infrastructure, China Harbour (Singapore) Engineering Company Pte Ltd (China Harbour) and ST Engineering Marine Ltd, the Marine arm of Singapore Technologies Engineering Ltd (ST Engineering), will design and build a 2,900 tonnes per day (tpd) WTE facility and a 250 tpd MRF as part of the IWMF Phase 1 development. To be co-located with PUB’s Tuas Water Reclamation Plant (Tuas WRP) at the Tuas View Basin site, the IWMF WTE facility and the MRF will be amongst the largest of such facilities in Singapore when they are completed in 2024.

Keppel Seghers, China Harbour and ST Engineering’s Marine arm’s share of the works under the EPC contract will be approximately 48%, 31%, 21% respectively.

Based on Keppel Seghers’ proven and proprietary WTE technology, the WTE facility will generate sufficient electricity to sustain the operations of Tuas Nexus IWMF Phase 1 and the initial phase of Tuas WRP, with excess electricity for export to the grid.

The state-of-the-art WTE facility will feature Keppel Seghers’ air-cooled grate, boiler design, and advanced combustion system. In addition, the facility’s wet flue gas cleaning system will ensure the facility’s emissions comply with Singapore’s regulatory requirements as well as standards. As the consortium lead, Keppel Seghers will also be responsible for the overall project management.

China Harbour will undertake the civil, structural and landscaping scope of the project, while ST Engineering’s Marine arm will be responsible for the construction of the MRF, power-island and the balance of plant.

With advanced technologies to sort metals, paper, cardboard and plastics automatically, the MRF will improve sorting efficiency, contributing towards the overall recycling rate in Singapore.

The consortium will work closely with NEA, as well as their consultants - a multi-disciplinary consultancy team led by Black & Veatch and AECOM, in association with Ramboll, for the design, construction and commissioning of this flagship project.

Dr Ong Tiong Guan, CEO of Keppel Infrastructure, said, “As a developer and operator of two of Singapore’s current four WTE plants, Keppel, together with its partners, is honoured to contribute further to Singapore’s sustainable urbanisation through this flagship project. This project, which will contribute significantly towards Singapore’s long-term waste management plans, is a testament to Keppel’s leadership in world class WTE technology and will reinforce our position globally as a competitive and reliable waste management solution provider.”

Singapore’s IWMF will mark the third integrated waste management project that Keppel Seghers has undertaken. Keppel Seghers has designed, built and is currently operating Qatar's Domestic Solid Waste Management Centre, an integrated waste management facility that is treating waste for the whole country. In addition, Keppel Seghers Hong Kong Limited is also currently building Hong Kong’s (HK) first Integrated Waste Management Facility off the coast of Shek Kwu Chau, with Zhen Hua Engineering Co. Ltd., which is also a company under the China Harbour Engineering Company in Beijing. HK’s IWMF is its first integrated waste management facility for municipal solid waste and is contracted to treat 3,000 tpd of mixed municipal waste.

Mr Tang Qiaoliang, President of China Harbour Engineering Company Ltd. (CHEC), said, “CHEC is honoured to participate, with its partners, Keppel Seghers and ST Engineering, in such a flagship environmental sustainability project and will fully utilise its expertise and strengths in the design and construction of civil, structural and landscaping, to complement its partners to deliver a world-class waste management solution.

“With the construction of HK’s IWMF, which is currently the first and largest WTE project in HK, progressing well, Singapore’s IWMF will be the second waste management facility to be built by Keppel Seghers and CHEC worldwide. In addition, CHEC also undertook construction of the Tuas Sewage Treatment Plant in Singapore in 2019. The strategic fit for Keppel Seghers and CHEC will create more opportunities for cooperation in the future.”

Mr Ng Sing Chan, President, Marine of ST Engineering said, “ST Engineering values industry collaboration, especially one such as this that helps facilitate Singapore’s drive towards environmental sustainability. We look forward to fulfilling our part in this consortium with our deep domain expertise in environmental engineering, and core competencies in managing large-scale engineering and critical infrastructure projects.”

The abovementioned development is not expected to have a material impact on the respective net tangible assets or earnings per share of Keppel Corporation Limited and ST Engineering for the current financial year.

1 The IWMF is a state-of-the-art flagship facility developed to help Singapore achieve greater environmental sustainability. Besides the WTE and MRF, the IWMF will also comprise a food waste treatment and sludge incineration facility.

SSE Thermal and CIP Commission Hitachi Zosen Inova to Construct New Energy from Waste Plant in England

Hitachi Zosen Inova (HZI) has won a contract to construct a new Energy from Waste plant on the Slough Trading Estate near London, England. The project has been developed by a Joint Venture consisting of energy group SSE Thermal and Copenhagen Infrastructure III K/S, a fund managed by Copenhagen Infrastructure Partners (CIP). The plant will use processed waste to generate around 46 MW of electricity per year. It will be the third project that the SSE Thermal and HZI have worked on together.

A Joint Venture consisting of UK energy group SSE Thermal and Copenhagen Infrastructure III K/S, a fund managed by Copenhagen Infrastructure Partners (CIP), has awarded Swiss cleantech company Hitachi Zosen Inova (HZI) the contract to build the new Energy from Waste (EfW) plant in Slough, to the west of London’s Heathrow Airport. Following the Ferrybridge Multifuel 1 and 2 plants in West Yorkshire, the Slough installation is already the third plant built by HZI in conjunction with SSE Thermal, and HZI’s thirteenth project in the UK.

Stephen Wheeler, Managing Director of SSE Thermal, said: “We are delighted to once be again working with HZI as we look to deliver another industry-leading Energy from Waste project. When completed, Slough Multifuel will play a key role in the UK’s sustainable waste management, diverting thousands of tonnes of waste away from landfill, and instead converting it into a valuable source of energy.”

Furtherly he emphasised the importance of the renewed cooperation: “During the construction of both the Ferrybridge Multifuel 1 and 2 projects in West Yorkshire, HZI and SSE were able to work together to deliver the plants safely and reliably. We are delighted to be able to work with HZI again to construct another Energy from Waste plant in the UK.”

Carefully Thought-Out Installation

The future plant will process around 440,000 tonnes per year of mainly commercial waste from the Greater London Area. The process will generate around 46 MW of electricity that will be fed into the national grid. Additionally, the plant will export up to 23 tonnes of processed steam per hour to a nearby food factory.

The new EfW installation will be constructed on SSE’s site on the Slough Trading Estate, where parts of a former plant have been decommissioned and demolished over the last year. One remaining feature of the former plant is the cooling tower which will also be integrated in the new facility.

Enabling works at the site is ongoing and to be completed by the end of 2020, with the first construction work on the site scheduled for 2021. The plant is expected to go into full operation in 2024.

Ragn-Sells and Hitachi Zosen Inova Build Facility for Processing Flue Gas Treatment Residues in Sweden

Swedish recycling company Ragn-Sells and Swiss cleantech company Hitachi Zosen Inova are to build a facility for processing flue gas treatment residues at Högbytorp, Sweden. The process enables salts to be extracted from the waste product which can then be reused in industrial and chemical processes.

The flue gas treatment residue processing facility being built at the Högbytorp site of the Swedish recycling company Ragn-Sells will collect and wash residues from industrial processes, enabling the recovery of various commercial salts. Following a joint project development phase, the client, Ragn-Sells Treatment & Detox AB, has commissioned the Swiss cleantech company Hitachi Zosen Inova (HZI) to supply and integrate the entire process technology.

“HZI is a well-known name in plant construction and has many years of process technology experience. These were crucial factors in our choice of partner for this project,” says Ragn-Sells project head Ulrik Améen.

Making a Sustainable Circular Economy Reality

With the objective of creating a sustainable circular solution, once commissioned the installation will extract useful materials such as various salts such as potassium chloride, sodium chloride and calcium chloride as well as ammonium sulphate from the residue. These materials can then be reused for industrial or chemical purposes.

For HZI this project marks a return to familiar territory: in the past the company has successfully developed and installed diverse fly ash washing systems at thermal waste treatment plants. “Given the various interpretations of the European legislation on treatment and landfilling fly ash and residues in different countries, the Ragn-Sells facility marks the way forward,” says Ruedi Frey, Senior Engineer at HZI. “We’re proud to be able to contribute our know-how and experience to this prestigious project.”

The responsible Service Manager at HZI, Stefan Forsberg, adds: “What makes this project special, is that we combine the proven ash leaching technology with brine cleaning and salt recovery for the first time.”

The solution produced by the washing process will then be vaporised in a distillation process, with the crystallised salts separated out. After that the cleaned residue will be dewatered and used as feedstock for new production processes.

Work to build the relevant section of the building will begin in autumn 2020, and assembly of the process technology will follow in January 2021.

Hitachi Zosen Inova to Build New Energy from Waste Plant for Covanta, Biffa and the Green Investment Group

To deliver the Newhurst project, its twelfth overall in the UK, Hitachi Zosen Inova will be acting on behalf of a consortium of developers comprising Covanta, Biffa and the Green Investment Group. Strategically located just off the M1 motorway in the East Midlands, the Newhurst EfW facility will treat up to 350,000 tonnes of non-recyclable municipal solid waste each year. Additionally, the modern installation will have one of the highest efficiency rates in the world.

Swiss cleantech company Hitachi Zosen Inova (HZI) won the public tender to build the new facility in Shepshed, Leicestershire (England). The clients are a consortium consisting of waste management companies Covanta and Biffa, together with the Green Investment Group. The project is HZI’s twelfth in the UK and, following Dublin (Ireland) and Rookery South (England), its third in collaboration with Covanta. “HZI is a proven provider in delivering world-class energy from waste facilities, and we’re delighted to be working with them again on this important project. Collaborating on the basis of trust is a key factor in the successful delivery of a major project of this type,” said Tom Koltis, Covanta’s Executive Director of European Development. HZI will serve as overall turnkey contractor, delivering the entire building construction, the procurement function and the technology for the Newhurst project.

Tailormade Design for Highest Energy Efficiency

The state-of-the-art plant will feature the continuously developed model of HZI’s air-cooled reciprocating grate and Hitachi Zosen Inova’s XeroSorp® dry flue gas treatment system. “The plant is equipped with a highly efficient flue gas treatment system that fully complies with the most stringent emission limits, and often does noticeably better,” explains Ingo Eifert, Project Director at HZI, who is responsible for the Newhurst project. He says that by installing XeroSorp® the plant operator will benefit on more than one level: “The size and design of the flue gas treatment system are geared to enhancing energy efficiency and also deliver a positive impact on water use.”

The Newhurst EfW facility is a significant addition to the UK’s waste management infrastructure. It supports both the government’s drive to reduce reliance on landfill and the UK’s ability to sustainably treat more non-recyclable waste without relying on export to European facilities.

The plant will provide 350,000 tonnes of annual treatment capacity for non-recyclable waste and will also generate up to 42 MW of low-carbon electricity, enough to power around 80,000 homes. With electrical net efficiency of 31.3%, the installation will also be one of the most energy-efficient in the world.

The facility will enter its operational phase in 2023.

Hitachi Zosen Inova - Swiss Technology for Swiss Waste Treatment Plant – A Decades-Long Collaboration Is to Continue

Hitachi Zosen Inova is to supply the combustion technology and boiler for an Energy from Waste project in Zuchwil, Canton Solothurn.

Since 1976 Hitachi Zosen Inova has been involved in building and overhauling the existing Energy from Waste plant (EfW) in Zuchwil. Now the Swiss company will supply its combustion technology and the boiler for the new KEBAG Enova Emmenspitz EfW plant, replacing the existing one. This is a major domestic order that consolidates the technology company’s position in its home market.

Swiss cleantech company Hitachi Zosen Inova (HZI), based in Zurich, has been awarded the contract to supply the combustion and boiler system for the new KEBAG Enova Emmenspitz Energy from Waste (EfW) plant being built by KEBAG AG in Zuchwil, Canton Solothurn. “We were immediately impressed by HZI’s technology. Its specifications precisely meet our needs and requirements for the new equipment,” explains KEBAG AG director Markus Juchli.

Proven Combustion Technology Optimised
Besides the feed hopper, boiler, dry bottom ash extractor and electrostatic precipitator, the scope of supply also includes HZI’s proprietary combustion technology. Part of this is a further iteration of the HZI grate, which combines the benefits of previous models to help increase overall plant efficiency by boosting operation and reducing maintenance.

Construction is scheduled to start in early Summer 2020. The existing plant will be dismantled once the new installation goes into operation. The two newly constructed combustion lines will be used to process 221,000 metric tons of source-separated municipal and commercial waste a year to generate up to 53.7 MW of thermal energy that will be fed into the respective grid as electricity or district heat.

Important Partner in Local Markets
Following the successful realisation of international large-scale EfW turnkey projects in recent years, HZI has also completed numerous small and medium-sized retrofit and refurbishment projects at existing plants in Europe (recently in Norway, Finland and Germany) and lot projects for new plants. The contract to supply the combustion system of the new plant marks an important continuation of a decades-long collaboration between HZI and the client, which started in 1976 with the installation of the first plant in Zuchwil, which was replaced and extended with HZI technology in the 1990-ies. Over the years, HZI has also been continuously involved in building and overhauling all four existing lines. With the delivery of the two new lines, this project marks the next generation. Markus Juchli also underscores HZI’s constant contribution: “Given that Hitachi Zosen Inova was involved in the construction of the existing plant and subsequent maintenance on a regular basis, we know that they have the experience and commitment to quality and reliability that we expect in a partner.”

In the next few months, HZI can also look forward to additional retrofit, renovation and service projects in parts of Switzerland as well as central and northern Europe – all of which will enable the Zurich-based technology supplier to capitalise on its many years of experience and specialist know-how.

HZI itself sees great potential in Switzerland in the medium and long term: In Europe and in other parts of the World such as Japan, EfW plants have been part of a long tradition of sustainable waste management. “Some of the older installations in this country are reaching the phase where refurbishment and modernisation could help substantially extend their service life while improving energy efficiency,” explains Sandro Malzach, Vice President Systems & Service at HZI. He continues with a look into the future: “HZI is ready for this and has the technology and know-how to provide plant operators with expert support.”

Keppel to supply technology solutions for waste-to-energy plants in India

Keppel Seghers Belgium N.V. (Keppel Seghers), a wholly-owned subsidiary of Keppel Infrastructure Holdings Pte Ltd (Keppel Infrastructure), has secured contracts to supply waste-to-energy (WTE) technology and services worth over EUR 12 million (approximately SGD 18 million) from Abellon Clean Energy Limited based out of Gujarat in India. These WTE projects would be first-of-its-kind in Gujarat.

Keppel Seghers will provide the core equipment, design, and technical services for the plant’s air-cooled grate and vertical boiler, which are designed to achieve efficient energy recovery and operational reliability. When completed, the facility can effectively reduce the volume of waste that goes to landfills by over 90%.

Dr Ong Tiong Guan, CEO of Keppel Infrastructure, said, “The amount of waste being generated by communities worldwide has been rising in tandem with rapid urbanisation and this is a challenge that has to be tackled responsibly. Modern waste-to-energy plants have proven to be an effective strategy to reduce the amount of waste going to landfills. Having successfully implemented over 100 WTE projects around the world, we look forward to delivering Keppel Seghers’ proven WTE technology that will contribute to the State of Gujarat achieving its waste management goals.”

As one of the most populous nations in the world, India produces one of the highest amounts of municipal solid waste, with only a fraction of it being treated. The majority of the waste is either landfilled or disposed in open areas. Therefore, waste-to-energy is garnering increasing attention as a viable waste treatment option for many states of India.

The above transactions will not have any material impact on the earnings per share and net tangible asset per share of Keppel Corporation for the financial year ending 31 December 2020.

Milestone order for Magaldi. The Ecobelt® WA technology seduces the Land of the Rising Sun.

On August 2019, Magaldi Group and KHI signed a contract with the Kyoto City management to equip the urban Waste-to-Energy plant with the Ecobelt® WA technology.

After the successful projects carried out in Europe, Magaldi was requested to bring its extensive know-how in dry bottom ash handling to retrofit the wet system in the Japanese WtE plant.

The Kyoto City Northeast Clean Center is equipped with two grate firing boilers (7.5 MWe each) burning 233,000 tonnes per year of municipal solid waste and producing a bottom ash rate ranging from 1.5 up to 7 t/h.

Currently the boilers are fitted with a wet system provided with several conveyors up to the final discharge point. The configuration designed by Magaldi is definitely simpler and consists of one conveyor for unit# 1 and two conveyors – one after the other – for unit #2.

The crucial factors that tripped the balance in favour of awarding the retrofit project to Magaldi were the drastic reduction in water consumption, the increased availability of the bottom ash handling system and a more effective metal separation ensured by the Ecobelt® WA technology. 

The latter allows the dry removal of hot bottom ash from grate boilers. By replacing the use of water with air as primary cooling medium, the result is an effective environmental risk mitigation and lower O&M costs because there is no need to dispose of or treat water.

Entirely enclosed in a dust-proof steel casing to prevent any spillage of material into the environment, the Ecobelt® WA promotes an intimate contact between air and ash particles, that maximizes the cooling process and the unburnt carbon conversion.

Ambient air used for ash cooling can be injected into the combustion chamber so that the relevant amount of energy, mainly in the form of ash sensible heat, can be recovered to increase the boiler efficiency.

Furthermore, the Ecobelt® WA system increases the yields of the downstream metals recovery process. As slag is discharged without the use of water, metals are neither quenched nor introduced to an alkaline environment, thus providing high-quality raw materials. In addition, the mineral fraction of bottom ash is not lumped together, making later separation of metals and mineral fraction easier and more effective.

Right Around the World: Hitachi Zosen Inova Supplies Technology for Energy from Waste Plant in Australia

Hitachi Zosen Inova is delivering its first energy-from-waste plant in Australia in East Rockingham near Perth. In addition to developing and constructing the state-of-the-art facility, the company will also part-own and cooperate it.

By the end of 2022 a new Energy from Waste (EfW) plant is to be built around 40 kilometres south of Perth in the state of Western Australia. The East Rockingham Resource Recovery Facility (RRF) project was developed by a consortium consisting of Swiss cleantech company Hitachi Zosen Inova (HZI) plus Australian project developer New Energy Corporation and Abu Dhabi developer Tribe Infrastructure. The contract to design, build and commission the plant was awarded by the project shareholders to an EPC consortium formed by Acciona Industrial and HZI.

HZI will be delivering everything from the waste crane to the stack in the form of its proprietary combustion technology, including the reciprocating grate and a highly efficient multistage flue gas treatment. Consortium partner Acciona will be in charge of civil construction, the water & steam cycle plant, the installation and erection of HZI’s equipment and the balance of the plant.

The EfW plant will process 300,000 tonnes of municipal and industrial waste a year from the domestic and industrial zones in the surrounding area under the jurisdiction of East Mindarie Regional Council (EMRC) and Cockburn Council. This will be used to generate 28.9 MWe of energy which will be fed into the grid, contributing directly to the supply of energy to the agglomeration around Perth.

Sustainable Waste Management for Australia

Even though there is no official ban on landfill in Australia, for some time people have been rethinking sustainability and efficient waste management. As one of the first of its kind in the country, Rockingham RRF will play a pioneering role and point the way forward for future EfW installations in Oceania. Marc Stammbach, Managing Director of HZI Australia, emphasises the relevance of the project for all concerned: “For HZI this project marks our entry into the Australian market and introduces our world renowned and leading technology to Australia – something we’ve been working on for a long time. For the Perth area this project marks a major step towards sustainability and renewable energy from waste.”

Supporting the Local Economy

Besides its contribution to environmental awareness, the project is also highly significant for the local economy. Alongside technical know-how from Switzerland, a large part of the material, equipment and productive capacity will be provided by regional and national companies. In addition to this, around 300 people will be employed temporarily on the site during the construction phase. After this the plant will be operated for at least 20 years by a joint venture between SUEZ and HZI, providing permanent operation and maintenance jobs for a further 40 people. HZI is also committing to this project long-term as a project shareholder.

Construction is scheduled to begin at the beginning of January 2020, so that the plant can go into full operation by the end of 2022.
