Sorting technology

SPEKTRUM BW sorting technology is ideal for use wherever light/ dark or dark/light materials need to be separated, such as when separating the dark rubber seals from the lighter PVC of window frames during recycling. A detector identifies material that is too dark or too light, its position is identified and precise ejection nozzles activate to blow out the contaminant. Throughputs of up to three tonnes per hour are possible, and units can be upgraded to full colour sorting capability.

Photoionization detector for volatile organic compounds

The MiniRAE Lite is the third in a series of third-generation photoionization detector (PID)-based instruments. The MiniRAE Lite is a non-intrinsically safe instrument that uses standard alkaline AA batteries or optional rechargeable batteries. This instrument is intended for outdoor and construction sites, or in composting and recycling facility environments where hydrocarbon-based volatile organic compounds (VOCs) and chemicals can pose a toxic threat. “The MiniRAE Lite joins the MiniRAE 3000 and ppbRAE 3000 in providing real results in real time with a measurement response time of under three seconds and is waterproof for easy decontamination and suitable for use in humid conditions.” explains Lisa Mork, director of marketing for RAE Systems. “The MiniRAE Lite has humidity compensation which makes it ideal for monitoring in rapidly changing environments, and as with all RAE Systems instruments, the MiniRAE Lite has a three-button interface designed to be easily used with up to three layers of gloves.”These units have a measurement range of 0 to 5,000 parts per million (ppm), and feature a large back-lit graphical display for easy viewing in any light conditions. It also features a built-in flashlight for operation in extremely dim environments. No tools are required to field-service the PID lamp or sensor or to replace batteries. The instrument includes a user interface that is configura-ble in 12 languages.

Optical sorter for glass and plastics recycling

Spektrum is a high-resolution optical colour sorter engineered to separate up to 90 percent of glass from ceramic, stone and porcelain waste. Units will also separate more than 98 percent off-colour contaminants from plastic streams such as coloured PET, contamination from recycled PVC and all types of granular or shredded plastics with a grain size down to below five mm.

X-ray technology used to sort glass

Varicon-X machinery uses X-ray technology to sort glass reclaimed from cathode ray tubes (CRTs), such as those used in televisions and computer monitors. Varicon-X technology has never before been used to separate CRT funnel glass, containing lead, from screen glass with a fluo-rescent coating, according to this manufacturer. These machines are able to process CRT glass at more than 30,000 tonnes per year, using normal shift patterns.
