A week-long testing and commissioning period for Phase III of the Bao'An Waste-to-Energy (WTE) facility in Shenzhen, China, was just successfully concluded.

Over the week, it diverted 35,000 tonnes of waste from the landfill and provided more than 20 GWh of electricity to Shenzhen city. The electricity generated in a week was enough to power 4,000 Singaporean HDB 4-room flats for a whole year.

This additional phase has added five incineration lines to the facility, each exceeds operational guarantees by treating over 1,000 tonnes of waste per day, bringing the facility's capacity to nearly 9,000 tonnes per day.

The heavyweight facility is now the largest operational WTE facility in the world - a testament to Keppel Seghers' capabilities in the field of large WTE capacities, - and will divert 3 million tonnes of waste from landfills, thus hugely reducing carbon emissions. The facility will provide electricity for more than 1 million citizens in Shenzhen continuously.

Steinmüller Babcock Environment GmbH based in Gummersbach has been awarded the contract for the modernisation of the Joint Venture Waste to Energy plant Ludwigshafen. The scope of supply and services includes planning and construction of the boiler system including grate and ancillary equipment for two lines. The client is the municipal operator GML - Gemeinschafts-Müllheizkraftwerk Ludwigshafen GmbH. Commissioning of the second line is planned for summer 2024.

With the project IGNIS (Latin: fire), the GML in Ludwigshafen is planning a comprehensive revamping of the Waste to Energy plant in order to ensure the waste disposal of the region for the next 25 years. In the plant, municipal and commercial waste from around 1,000,000 people from the region are thermally recycled. The Joint Venture Waste to Energy plant Ludwigshafen was built over 50 years ago, the two oldest of the three boilers are now 30 and 23 years old. A full revamping of the three lines would not be economically viable, and so GML consequently decided to invest in two new Waste to Energy lines replacing two of the existing lines which will be dismantled. Thus, the two new lines can be set into operation without restricting the operation of the existing three lines too much. On average, 90% of capacity will be maintained over the five years of reconstruction.

Depending on the operation status of the boilers the two new lines will contribute 90,000 – 100,000 t/a per year each to the overall plant treatment capacity of 235.000 t/a, with a thermal boiler performance of 30 MW each. The boilers generate high-pressure steam, which is converted into district heating and electricity in the neighbouring district heating plant of the regional supplier TWL AG. Steinmüller Babcock convinced in the tender with a technical concept combining a tailor-made solution with an overall attractive economic offer.

Four energy-from-waste plants are to be constructed in Moscow Region. A consortium consisting of the Swiss clean-tech firm Hitachi Zosen Inova and the Russian technology company ZiO-Podolsk was awarded the contract by the client, the Russian operating company Alternative Generating Company. The plants will make a substantial contribution toward reducing the number of landfill sites by treating the residual waste of around 5 million inhabitants, while at the same time delivering electricity for around 1.5 million people.

On 11 July 2019, the Russian power plant operator Alternative Generating Company-1 (AGC-1), an SPC and part of the RT-Invest Group and a consortium of the Swiss-Japanese cleantech firm Hitachi Zosen Inova (HZI) and the Russian technology company ZiO-Podolsk (a subsidiary of Atomenergomash (AEM), signed the contract to be the technology provider to build four energy-from-waste (EfW) plants in Moscow Region. HZI and AEM will deliver all of the process technology, including HZI’s first-class combustion technology and state-of-the-art flue gas treatment. In addition, the consortium will be responsible for a range of overarching services and monitoring processes. This is HZI’s first project in Russia.

Moscow’s War on Landfill
The idea of EfW is relatively new to Moscow Region and Russia in general. A total of four EfW plants (Moscow 1-4) are to be constructed on the city’s land over the next years. Construction of the first plant has already begun around 80 km southeast of the city center. The new plants form part of the Green Tariff, a programme to promote renewable energy launched in 2017. In addition to subsidies, the new facility will be funded by waste disposal fees and the sale of electricity and bottom ash.

The EfW plants will help the city to optimise its waste management by closing and steadily reducing its many landfill sites. Each plant will process some 700,000 tonnes, this is a total 2.8 million tonnes, of residual waste per year, the waste volume from more than 5 million people, generating 75 MW of electricity per plant. Part of the electricity will be used to run the plants, and part will be fed into the grid supplying power to around 1.5 million people in Moscow. Andrey Shipelov, CEO of RT-Invest, comments: “The integration of EfW technology is an important milestone in the introduction of a progressive and sustainable waste management economy in Russia. As a company, we are pleased to be playing a key role in the construction and operation of Moscow Region’s plants.” Bruno-Frédéric Baudouin, CEO at HZI adds: “We are proud to deliver our proprietary, proven technology, and to be part of this important project in Russia.”

Proven Technology Adapted to Meet Local Needs
The four plants will feature a similar design and state-of-the-art HZI technology that is already in use at several hundred sites around the world. This includes combustion with the HZI Grate, the water-steam cycle, and a multi-stage HZI flue gas treatment system that meets all European emissions standards and even falls well below the current limits.

Geographical factors pose additional challenges in terms of construction and installation. “The weather and climate here are different to Central Europe, for instance, and we have had to take account of this in the structural design,” explains Urs Altenburger, the Sales Manager responsible at HZI. Some technical systems that are normally placed outdoors have been moved indoors in order to protect them from the extreme cold in winter.

Promoting Local Businesses
The construction of the four EfW plants will not only bring benefits for Moscow Region in terms of waste management. The local economy will also profit, since much of the equipment and materials used will be Russian. A large number of jobs will also be created. Around 130 people will be needed to operate each completed plant, and up to 800 will be working on each site at any given time during construction.

Rookery South Limited have awarded the contract to construct England’s latest EfW plant to the Swiss company Hitachi Zosen Inova, building on successful collaboration forged in earlier projects. In the future, the Rookery South plant will process 545,000 metric tons of solid municipal and commercial waste a year to generate more than 60 MW of electricity for the national grid.

The signing of the contract on 21 March 2019 signals the next step in the construction of a new Energy from Waste (EfW) plant in Bedfordshire around 100 kilometers north of London. The Rookery South Limited operating company, jointly owned by Covanta, Green Investment Group and Veolia, has granted the contract to Swiss cleantech company Hitachi Zosen Inova (HZI), building on a partnership going back to earlier joint projects. HZI and Veolia can look back on the successful delivery of the Newhaven project in 2011, while HZI built the Poolbeg plant in Dublin, which went into operation in 2017, on behalf of Covanta.

“We are pleased to continue our partnership with Hitachi Zosen Inova for the construction of the Rookery South Energy Recovery Facility,” said Covanta Senior Vice President of Engineering and Projects Anne Michelini. “Following our recent success in Dublin, Ireland where we partnered to build a world-class Energy from Waste facility, I’m confident of our ability to achieve similar results with the Rookery project.”

Important Contribution to UK’s Waste Management Efforts
Rookery South is already the Swiss company’s eleventh project in the UK. With an overall waste throughput of up to over 3.9 million metric tons a year in the future, HZI’s EfW installations are already crucial to the UK’s sustainable waste management efforts. “Over more than a decade, the UK has become a particularly important market for HZI with an awarded waste capacity of almost the total capacity of smaller European countries such as Switzerland”, says Andres Kronenberg, Chief Business Development Officer at HZI.

With three combustion lines processing around 545,000 metric tons (585,000 t max.) of mixed municipal and commercial waste annually, the Rookery plant will play an active part in the UK’s endeavors to reduce or eliminate the need for landfill and exports of refuse and, will therefore play a role in reducing of the UK’s greenhouse gas emissions. During the process the installation will also generate more than 60 MW of electricity energy, which will be fed into the national grid to increase the benefits to society even further.

“The Rookery project adds major value for all concerned. It’s a boon not only for the UK’s waste management and energy, but also for us as a general contractor, as it underlines the trust, our clients and partners have in HZI”, says Andres Kronenberg, emphasising the relevance of this latest project.

Work Already in Full Swing
The scope of supply for the turnkey plant also covers the entire building construction. The first engineering tasks, and initial work on the site, are already in full swing. For example, preliminary work such as the construction of a pond to prevent flooding was initiated several months ago. Access roads are already open, and additional planning work to ensure safety and efficiency has been done to enable construction to begin as soon as the contract is signed.

The local economy will also benefit: over the next 39 months several hundred people will be working on the plant simultaneously at peak periods. Efforts to hire local people for various phases of the construction are also at an advanced stage. When the plant will go into operation in 2022 another ca. 60 long-term jobs are planned to operate and maintain the installation.

MARTIN's licensee in China, Sanfeng Covanta Environmental Industry Co., Ltd, has been awarded 12 new projects with MARTIN reverse-acting grate SITY2000 technology. 11 in China, 1 in Thailand. The total 18 combustion lines have a capacity of 10,750 ton per day.

Babcock & Wilcox Enterprises, Inc. announced that its Denmark-based subsidiary, Babcock & Wilcox Vølund, and its project partner, Interserve, have successfully turned over a renewable energy plant project near Dunbar, East Lothain, Scotland, to the customer, Viridor.

The Dunbar Energy Recovery Facility, a municipal waste-to-energy plant, will provide green power for 39,000 homes while providing more than 50 permanent, full-time jobs for the community. B&W Vølund’s advanced waste combustion technology also will help the community dramatically reduce its reliance on landfilling by processing 320,000 tonnes of municipal and construction waste annually that would otherwise end up in a landfill.

This project is one of four European renewable energy projects B&W previously announced it expects to turn over to customers in the first and second quarters of 2019. The Dunbar project was referred to as the “sixth project” in B&W’s previous public disclosures about its European Renewable projects.

“B&W’s Vølund’s advanced technology is proven and reliable for waste-to-energy customers worldwide and we’re proud to have executed this important project for Viridor,” said B&W Chief Executive Officer Kenneth Young. “The Dunbar facility, which features B&W Vølund’s state-of-the-art DynaGrate® fuel combustion system, will be able to process up to 38 tons of municipal waste per hour, deliver power to thousands of local homes and businesses, and help the Scottish government meet its target of landfilling zero biodegradable municipal waste by 2021.”

“Successful turnover of this project was an important step forward for B&W and reflects the hard work and strong dedication of our project team and highly skilled employees,” Young said. “We remain focused on completing our remaining European projects while we streamline overall operations, reducing overhead costs and enhancing the strength of our core technologies and services that establish B&W and its brands as a true global leader.”

The plant features two B&W Vølund boilers and the advanced DynaGrate dynamic fuel combustion system, steam turbine and B&W emissions control equipment. B&W Vølund’s DynaGrate is one of the most-reliable combustion grates on the market and is tailored to the waste-to-energy and biomass energy industries. It provides excellent performance with low maintenance costs due to a design technology that reduces wear and tear on components.

Compared to other grate technologies, the DynaGrate combustion technology also produces significantly less fly ash, reducing the generation of secondary waste to landfill while allowing for recovery and recycling of all ferrous metals from the bottom ash.

Over the past 80 years, B&W Vølund has supplied more than 500 combustion grates worldwide.
