Recycling

Materials analysis utilising radiation detection and measurement technologies is an integral component of numerous industrial processes. Southern Innovation’s SITORO® digital pulse processing technology improves detection speed and accuracy in materials analysis which, in many applications, is a time critical element of the industrial process. 

Southern Innovation’s SITORO digital processing technology enables world leading performance (speed and accuracy) for radiation-based sensing applications that resolve the saturation and pulse pile up  limitations which restrict conventional approaches.  Coupled with full spectrum X-ray transmission  scanning, this key enabling technology facilitates bulk sorting where other particle-by-particle techniques have been too slow.

The SITORO approach has fundamental advantages over other scanning technologies, including analysis time (results in milliseconds), superior throughput and freedom from any permanent radiation sources.

Glass Cullet Recycling & Contamination Removal

“Glass is 100% recyclable,” says Robert Weisenburger Lipetz, executive director of the Glass Manufacturing Industry Council (GMIC), a non-profit trade association. “It has an unlimited life and can be melted and recycled endlessly to make new glass products with no loss in quality”.

Cullet, the term given to crushed recyclable glass in its many varied forms, can be reintroduced into the glass manufacturing process to reduce the requirement for raw materials.   Manufacturing glass from recycled cullet requires up to 75% less energy than using virgin material, due to the lower production temperature required.

However, many waste stream sources of recyclable glass are comingled with other materials, including steel, aluminium and ceramics.  Even small quantities of contaminant can create significant defects in flat glass products, which to date has limited the potential for higher recycled glass content.

Southern Innovation’s GlassScan equipment can significantly increase the proportion of cullet that can be confidently recycled, enabling significant energy intensity and emissions reductions opportunities for float glass manufacturers globally.  GlassScan detects contaminants to a much finer resolution than any other bulk sensing technology, and diverts this waste, leaving a stream of clean, high quality cullet, free from contamination and ready to feed into the glass manufacturing process.  Configurations between 10 and 100 tonnes per hour are available, customised to the specific client requirements.

Battery Sorting & Recycling

X-ray fluorescence (XRF) techniques involve irradiating a sample with X-rays and observing the resulting X-ray fluorescence emitted by the sample.

Originally used to analyse geological samples, XRF has now developed an extraordinarily broad array of applications in fields including defence and security, environmental rehabilitation, food chemistry, agriculture, metallurgy, geology and waste monitoring. XRF spectroscopy is widely used to measure the elemental composition of materials. It provides a very accurate method to measure the composition of materials and is used in the quality control of many industrial processes.

As with XRD, this method is fast and non-destructive to the sample. XRF is a cost-effective method to quickly assess samples, both qualitatively and quantitatively, for contaminants (such as heavy metals and other substances in paint, food, fuel, soils and water).

Researchers at the Australian Synchrotron led by Dr Martin de Jonge used X-ray fluorescence microprobe results, which relied on SITORO® Accelerated Analysis, to create a 3D reconstruction of the distribution of trace elements in an ant mandible. Ants are significant agents of ecosystem processes, and understanding their role in accumulation and movement of elemental metal can aid in development of innovative mineral prospecting methods.
