Vietnam: The government of Quang Ngai has threatened to shut the Dai Viet-Dung Quat cement plant if it does not improve its dust emissions. 107 households living within 50m of the unit have been moved but more than 1600 households remain close to the site, according to the Vietnam News Agency. The 0.5Mt/yr cement plant started operation in 2015.

Ireland: Irish Cement has been fined for dust emissions at its Limerick plant. The subsidiary of CRH was convicted by a local court of breaching its industrial emissions licence in April and May 2017 due to ‘fugitive dust emissions,’ according to the Limerick Leader newspaper. The cement producer pleaded guilty to the charges brought by the Environmental Protection Agency (EPA) and it has been fined Euro1250.

During the court session it was revealed that on one of the days of the dust emissions there were dry conditions with a north-easterly wind that exacerbated the situation. There was also a dust leak as a result of a missing bolt from one of the chutes in a clinker silo as well as a number of infrastructural issues. Irish Cement says it has implemented a number of remedial measures such as replacing the missing bolt and replacing gravel around the site with grass or concrete. It has also conducted a risk-assessment of the whole site. The producer committed a similar offence in 2006.

US: BinMaster has launched its new DD-3000 Dust Alert sensor product. The product is targeted to detect baghouse leaks when installed in stacks, ducts or pipes. The sensor is designed to save time by eliminating the need for manual inspections, reduce maintenance and prevent emissions and downtime.

The product uses inductive electrification technology to detect when particulate emissions exceed a preset level. As particles flow past and over the sensing probe, they induce a charge into the probe that creates small electrical currents. This method minimises the influence of sensor contamination, particulate velocity change or temperature drift.

Sensor models are available with either an alarm relay, generally used to alert to a need for maintenance, or a 4-20mA transmitter output option used for monitoring trends and compliance.

Spain: The Port of Alicante is undergoing a Euro3m upgrade to build a new dock that can support larger vessels. Once completed the upgrade will allow ships with a length of up to 240m to dock, according to the Diario Informacion newspaper. Previously the port could only support ships of up to 165m. The site processes large volumes of cement and clinker and dust mitigation measures are also being installed.

Australia: The New South Wales Environment Protection Authority (EPA) has fined Port Kembla Milling’s cement and slag grinding plant US$23,000 for allegedly storing raw materials in the open, in breach of its licence conditions. Raw materials, including gypsum and limestone, were allegedly stored in the open at the subsidiary of Cement Australia on at least five occasions since January 2016 in breach of the site’s planning approval and licence conditions. Such materials should be stored in an enclosed location to prevent dust emissions.

“The requirement to store materials in an enclosed building is a key way to ensure dust emissions from bulk materials are prevented. A measure that is very important given the residential areas near Port Kembla port,” said EPA Regional Director Metropolitan Giselle Howard.

In addition to the fines, the EPA has also required Port Kembla Milling to complete an independent raw materials handling audit to confirm appropriate storage and management systems are put in place. The company has made some initial steps to respond to this request, and the EPA will continue to work with the licensee to ensure full compliance.

Tanzania: The government has given Tanzania Portland Cement two months to reduce its dust emissions or face closure. Alphaxard Kangi Lugola, the Deputy Minister of State in the Vice President's Office (Union and Environment), said that dust from the plant was causing health issues with local residents, according to the Citizen newspaper. The National Environment Management Council will monitor the plant for compliance. The cement producer said that the plant would work on reducing its emissions.

Poland: BWF Envirotec Group has purchased Orwat Filtertechnik. Based in Mysłowice, Silesia, the company has been producing and distributing filter bags and filter pockets for dedusting and flue gas cleaning technology as well as pockets, cartridges and compact filters for air conditioning and ventilation technology since 1995. The company also has a sales office in Warendorf, North Rhine-Westphalia in Germany giving it a European presence. No value for the acquisition has been disclosed.

"Orwat Filtertechnik, with its technologically outstanding equipment, is an excellent addition to our line-up with a high level of benefit for our customers, particularly for plant builders and operators of flue gas cleaning systems,” said Stefan Offermann and Philipp von Waldenfels, managing partners of BWF Group. They added that the acquisition also strengthens its Offingen-based headquarters.
