by with No Comment News

Maire Tecnimont S.p.A. announces that its subsidiary MyRechemical, NextChem’s subsidiary dedicated to Waste-to-Chemicals technologies, has been awarded by Alia Servizi Ambientali S.p.A. a basic engineering contract for a waste to methanol and hydrogen plant to be located in Empoli (Tuscany), Italy.

The scope of work includes basic engineering design of the plant and the provision of necessary documentation to start the plant’s public authorization process with the Tuscany region. The basic engineering phase is expected to be completed by the end of 2022. 

Once authorized and completed, the plant will process 256,000 tons/yr. of non-recyclable waste and will produce 125,000 tons/yr. of methanol and 1,400 tons/yr. of hydrogen. The plant will benefit from MyRechemical’s chemical conversion technology which allows the recovery of waste that cannot be mechanically recycled, or other types of unsortable dry waste (i.e. Refuse Derived Fuel – RDF). The carbon and hydrogen contained in the waste are converted through a gasification process into a synthesis gas, which is used to produce low-carbon methanol and hydrogen. This process avoids the emission of pollutants in the atmosphere. Methanol is used as an alternative fuel for sustainable mobility or as a secondary raw material in the chemicals and manufacturing industries. Hydrogen can be used in low-carbon industrial processes to decarbonize hard-to-abate and energy intensive industries.

Alessandro Bernini, Chief Executive Officer of Maire Tecnimont Group and NextChem, commented: “This is one of the more interesting waste-to-chemicals initiatives that Maire Tecnimont is developing in Italy. This is the first application worldwide of an integrated technological scheme that allows to produce methanol from waste for sustainable mobility and hydrogen that will substitute methane in glass production processes, enabling both recycling and industrial symbiosis. It responds to the core need of circular economy and creates the bases of a new era of waste as a resource”.

“It will be possible to push the limits forward in recovering material from waste only by using more technology and innovation. We have signed a strategic partnership with Maire Tecnimont, leader in the Italian chemistry tradition”, commented Alberto Irace, Chief Executive Officer of Alia, “This represents a model of strategic alliance for circularity where Maire Tecnimont, Zignago, Suez and Alia, all leading companies in technology and industry, are joining their forces to design and realize a sustainable future”.

Keppel-led consortium secures S$1.5 billion EPC contract to develop Singapore’s Tuas Nexus IWMF

by with No Comment News

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.

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.
