Mixed Municipal Solid Waste Sorting
Municipal solid waste (MSW) contains recyclable fractions, such as plastics, mixed paper, cardboard, and metals. The demand for these materials is rising, compared with that for primary resources.
Traditional (manual) or semi-automated techniques, however, are only able to recover low levels of separate materials from mixed municipal waste streams and mean considerable content going to landfill.
In contrast, TITECH’s fully automated, state-of-the-art, sensor-based municipal sorting systems convert complex and varied - even dirty - municipal solid waste streams into high quality, separated, marketable output. The systems also make manual sorting unnecessary, thus reducing labor costs and material loss, while increasing efficiency.
Operationally, through using detection techniques such as near infrared (NIR), x-ray transmission (XRT), color line cameras and metal sensors in combination, TITECH municipal sorting systems offer:
- High recovery ratesHigh throughputs
- High purity levels – up to 98%Speedy return on investment
- Attractive running expenses, even in low-cost countries
- Advanced recognition capabilities (material, color, atomic density etc)
TITECH sorting systems identify and sort grain sizes from 10 to 500mm, separated according to preferred size ranges. They also provide complete future flexibility, through the ability to react quickly and cost-effectively to changes, such as new regulation and alterations in material input streams.
TITECH’s waste sorting technology provides inert material elimination of up to 95% in municipal waste, producing material suitable for biomethanisation. Inert material, such as glass and stones, can cause significant problems during the treatment process and therefore has to be reduced to a minimum, while as little organic content as possible is removed.
The sensor-based systems deliver this benefit by initially removing metals and plastics, through the TITECH municipal solid waste autosort detecting and sorting out different polymer types, for example, and the TITECH x-tract then identifying and separating glass and stones, based on atomic density measurement.
