Ireland: Irish Cement will burn used tyres in a bid to cut costs and secure jobs at its Limerick plant. The company plans to switch to dry waste material such as rubber from used tyres and plastic to heat the kiln at the plant. The switch will cut costs, make the plant cleaner and more competitive, according to the company.

A spokesman for Irish Cement said that the company would shortly be lodging a planning application with Limerick City and County Council for the replacement of fossil fuels with alternative fuels and raw materials to improve the sustainability of their operations. The company will also be seeking a revision of its licence from the Environmental Protection Agency.

"Limerick is Ireland's oldest cement plant, having commenced operations 77 years ago. Its continuous operation has been sustained by continuous investment in new technologies and processes. After the recent period of reduced demand, production is once again on the increase at home and abroad for cement. This fuel replacement programme will be key to sustaining this growth," said Plant Manager Pat Robinson. "Based on experience in other cement plants in Ireland and throughout Europe, the opportunity to reduce our dependence on imported fossil fuels will prove critical to our ability to operate competitively and sustain jobs at Irish Cement Limerick into the future."

Tanzania: Dangote Cement has signed two agreements that will enable its US$600m cement plant in Tanzania to generate 150MW from coal.

One agreement is with Tancoal. Dangote Cement has also signed a coal prospecting licence for a site in Mbinga. However, the plant will first run on diesel until it is able to generate its own electricity from coal.

The deals ends a year-long dispute between the government and the cement plant after Tanesco failed to provide electricity. The plant was considering importing coal from South Africa, which was a cheaper option than buying it from the area.

The cement plant is expected to reduce cement prices by 50% once production commences in early 2016. It will take advantage of the growing construction industry, which contributes 12.5% to the country's GDP. It will offer more than 1500 direct jobs and 9000 indirectly.

China: Eleven people have been detained in Yangchun, south China's Guangdong Province, after demonstrations against a project to build a waste incinerator adjacent to a cement plant turned violent.

Protesters said the demonstrations drew hundreds of people agitated over the risk of pollution from the project."How will we survive breathing in noxious smoke?" said one of the protestors.

Tension persisted for two days, with protesters saying that hundreds of people had been gathering near the gates of the cement plant.

Germany: SPECTRO Analytical Instruments has launched a new application brief detailing the advantages of using energy dispersive X-ray fluorescence (ED-XRF) spectrometers to perform elemental analysis in the field on soil and sewage sludge samples.

Determining the best course of action when addressing a contaminated environmental site requires precise identification of the contaminating elements and a determination of the amounts present. Traditionally, this elemental analysis has been done in laboratories using inductively coupled plasma-optical emission spectrometry (ICP-OES), however, transporting soil and sewage sludge samples back and forth from the field to a laboratory adds considerable time and cost to the remediation process.

The new brief, 'Analysis of Soil and Sewage Sludge in the Field with a Portable ED-XRF Spectrometer,' describes new improvements in portable ED-XRF spectrometers that enable environmental professionals to rapidly characterise samples in remote areas with minimal preparation and with very high accuracy of analysis in environmental monitoring, geochemical prospecting and mining applications. The benefits versus laboratory-based elemental analysis include speed, precision, accuracy and cost-effectiveness.

The brief also outlines key factors to consider when comparing various portable ED-XRF spectrometers and their variations in performance, ease of use and suitability for the field analysis of soil and sewage sludge samples.
