US: Charah Solutions has installed its MP618 thermal beneficiation technology at its terminal in Sulphur, Louisiana. The upgrade is intended to improve the quality of fly ash and to increase its supply of marketable fly ash to concrete producers. The proprietary process reduces loss on ignition, ammonia, activated carbon and moisture in fly ash.

The company hopes to provides concrete product producers and builders with a source of Class F fly ash to support a growing number of construction projects in the greater Lake Charles and Sulphur region. The Sulphur terminal is Charah Solutions’ second barge-supplied location in southern Louisiana. Its LaPlace, Louisiana terminal currently serves customers in Louisiana, Mississippi and Alabama.

India: Power stations owned by the Government of Madhya Pradesh are struggling to dispose of fly ash. The power companies were required to dispose of all fly ash in applications such as cement production or construction projects by the end of 2017, according to the Times of India newspaper. However, less than 20% of fly ash has been disposed of from the Shri Singaji Thermal Power Station (SSTPS) and only 20% fly ash has been disposed of at the Satpura Thermal Power Station (STPS).

An employee of a power plant quoted by the newspaper said that the power companies were able to dispose of fly ash where cement plants were nearby but that they found it a ‘great struggle’ elsewhere. A K Nanda, the managing director of the Madhya Pradesh Power Generation Company, said that the STPS had received no interest for an expression of interest since mid-2018. He added that the company was also approaching cement-based industries through social-media channels.

An estimated 0.22Mt/yr of fly ash will be sold from the Boundary Dam and Shand Power stations.

US: Charah Solutions has launched a proprietary fly ash thermal beneficiation technology that improves the quality of fly ash. It says that its new MP618Multi-Process technology reduces loss on ignition (LOI), ammonia, activated carbon and moisture in fly ash.

The technology allows for the beneficiation of both wet and dry fly ash. It advantages include lower costs, self-contained environmental controls that can be deployed in weeks, as opposed to years and a modular design that can be scaled up or down to increase production based on market demand.

MP618 can process both wet and dry fly ash. It can be installed at both operating and non-operating power plants, regardless of whether the fly ash is current production or legacy ash stored in ponds or landfills. The technology also allows for the processing of kiln dust to remove mercury for emissions regulations compliance. With the introduction of MP618, Charah Solutions expects to increase its supply of marketable fly ash to concrete producers and add greater value to its utility customers.

“MP618 will expand our MultiSource materials network, a unique distribution system of more than 30 nationwide sourcing locations, and improve our ability to provide a continuous and reliable supply of supplementary cementitious materials, including quality fly ash and slag cement, for ready mix concrete producers and other customers throughout the US,” said Scott Ziegler, Vice President of Byproduct Sales at Charah Solutions.

India: A joint-venture project involving the Steel Authority of India (SAIL) to build a new cement plant at Sundargarh in Odisha has stalled. Following support by local politicians for the plans in February 2017 no further action has been taken, according to the New Indian Express newspaper. SAIL originally made plans in 2006 to use blast furnace slag from the Rourkela Steel Plant and fly ash of NTPC-SAIL Power Company for the unit.

India: The Singareni Thermal Power Plant based in Pegadapalli in Telangana is supplying around 4000t/day of fly ash to local cement producers including Orient Cement, Kesoram Cement and others companies. The 1200MW coal power is part of the Singareni Collieries Company, according to the Hindu newspaper. The management of the plant believes that they achieved a record in 2017 – 18 by utilising over 91% of the fly and bottom ash generated by the power plant.

Vietnam: The environment ministry has approved fly ash from the Formosa steel company for use in cement production. Sông Gianh Cement in Quảng Bình Province has been cleared for its use provided the materials meet current technical specifications and that the company has the responsibility to monitor the transport of ash, according to the Viet Nam News newspaper.

Sông Gianh Cement initially denied receiving fly ash from Formosa. However, the transport company carrying the by-product from Hà Tĩnh to Quảng Bình admitted to local media that it had been hired for the job. The Quảng Bình environment department then revealed that Sông Gianh had asked the government if it could buy fly ash from Formosa but that it had been denied due to poor public opinion regarding the steel producer.

Formosa received widespread public criticism when it was blamed for a chemical spill into the sea in 2016 that caused mass deaths of marine life and public outcry.
