Bangladesh: The Bangladesh Cement Manufacturers Association (BCMA) has asked for import tariffs on clinker to be reduced. In a letter to the National Board of Revenue (NBR) it requested that the duty be cut to either US$2.40/t or a fixed rate of 5%, according to the Dhaka Tribune newspaper. Importers pay around US$6.00/t at present. The BCMA argues that the cement industry is paying more than other industries for its imports.

The association has also called for value added tax (VAT) on raw materials to be cut to 5% from 15%, reducing advance income tax to 2.5% from 5% and exempting regulatory duties for fly ash and import duties for cement bulk carriers.

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.

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.
