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.

UK: International recycling and waste management company Suez opened a new solid recovered fuels (SRF) plant in Rugby, UK on 18 September 2015. It will supply the Cemex Rugby cement plant with SRF for the next 25 years.

Suez's SRF plant will convert waste from across Warwickshire, Northamptonshire and the wider Midlands area into Climafuel®. Suez will supply Cemex with 240,000t/yr of Climafuel; 200,000t/yr from its SRF plant in Rugby and 40,000t/yr from its SRF plant in Birmingham.

The Rugby SRF plant was built as part of a 25-year deal between Suez and Cemex that was signed in 2012. Suez leased land opposite Cemex Rugby from Cemex in 2013 and construction of the Euro25m SRF facility began in 2014. The commissioning of the equipment took place earlier in 2015.

The SRF facility can process up to 300,000t/yr of waste. Around 70% of the input material comes from businesses in the region, while the remaining 30% is household waste, much of it originating from Northamptonshire County Council. The majority of the waste would otherwise be destined for landfill, but the SRF process enables Suez to extract recyclable materials, which, processed any other way, would be too contaminated to viably recycle.

"We are very pleased to officially open the Rugby SRF facility and formally mark the start of this long-term partnership between Suez and Cemex," said Jean-Marc Boursier, senior executive vice president of Suez in charge of the recycling and waste recovery division for Europe. "Suez is investing considerably in infrastructure to produce sustainable industrial fuels in the UK. The group now supplies 1.1Mt/yr of SRF worldwide. This solution gives us the ability to extract recyclable materials that would otherwise have been lost. It provides Cemex with a sustainable, long-term alternative to fossil fuels. This inauguration is a symbol of our commitment to the production of renewable energy fuels. Energy derived from SRF offers numerous advantages, because it is renewable, transportable, abundant and economically attractive."

Vietnam: Holcim is using shoes as an alternative fuel in Vientam thanks to its new solid recovered fuel (SRF) plant from shredding specialist Untha, according to Equipment World.

The new SRF plant will use waste from Vietnam's largest shoe factory once it has been delivered. It was pre-assembled and tested in Austria and is currently being shipped by sea to Holcim in Vietnam. Delivery is expected in September 2015. The SRF plant will convert the waste by using an anti-explosive Atex-specification XR3000 Cutter waste shredder with two 113kW motors, conveyor, over-band magnet, control room and water-powered fire suppression technology. The plant can process 10t of material into the 8mm, high calorific value fuel.

UK: Axion Polymers has invested significantly in new laboratory and testing facilities to ensure consistent quality of its solid recovered fuel (SRF) products and to satisfy the stringent standards of its technical end markets.

It has installed a laboratory-scale furnace at its large-scale processing facility, Shredder Waste Advanced Processing Plant (SWAPP), in Trafford Park, Manchester to enhance accurate measurement and testing of the physical and thermal properties of its Axfuel® SRF 30, an alternative fuel used by the cement industry, among others.

Axion has also recruited a quality control team working within ISO 9001 operating procedures to conduct in-house product testing, including analysis on critical aspects such as SRF calorific value and chemical composition. Samples are sent on a weekly basis to external laboratories for further testing and verification.

Derived from automotive shredder residue, Axfuel SRF 30 is a sub 30mm-sized mixture of textiles, fibre-fluff, plastic, foam and rubber, with a gross calorific value of 18 - 22MJ/Kg and available in large tonnages.

"We have made this important investment because alternative fuels from waste need to be treated as a product, not as a waste. If SRF is to deliver the fuel benefit and meet the technically-demanding specifications of our end markets, it has to be of consistently high quality so customers can buy with confidence," said Axion director Roger Morton. "By operating within strict quality controls, we can ensure our reliable supply of SRF is produced to exceptionally high standards. As this fuel is sourced from end-of-life vehicles, giving it a second life as an alternative high-energy feed is going to be an attractive option for companies who want to demonstrate their environmental credentials."

Vietnam: Deputy prime minister Hoang Trung Hai has directed the implementation of solutions to treat waste at thermal power plants for energy conservation and environmental protection.

Trung Hai urged the concerned parties to more effectively implement Government Decision 1696/QD-TTg on measures to treat gypsum, ash and cinder from thermal power, chemical or fertiliser plants for the production of building materials. Special focus should be paid to the Vinh Tan in Binh Thuan, An Khanh in Thai Nguyen, Song Hau in Mekong Delta Hau Giang and Vung Ang in Ha Tinh thermal power plants, where waste treatment is a pressing issue.

He asked the Ministry of Industry and Trade and the Ministry of Construction to coordinate with localities to disseminate effective waste treatment models while supplementing and completing criteria on the quality of ash and cinder for recycling in cement and construction material production.

Vietnam is home to 19 operating thermal power plants with a total capacity of 14,480MW, which discharge about 15Mt/yr of ash and cinder. After 2020, the country is expected to have 43 thermal power plants with a combined capacity of 39,020MW, discharging over 30Mt/yr of ash and cinder.
