This means that more of the raw material gets packed, less goes back to melting and the pack-to-melt ratio is thus higher. This in turn means less energy input and less CO2 emissions per glass container and at the same time a higher output for the manufacturer. Thanks to Bucher Emhart Glass technology.
With sensors and closed loop products, defects are detected and identified, and processes are adjusted automatically along the production line to avoid such defects, thereby increasing the pack-to-melt ratio.
Video: "GobRadar" is a camera-based gob observation and measurement system (sensor) providing a number of measurements for each and every single gob, such as weight, length and shape, enabling closed loops like closed-loop weight control.
Applying general assumptions and estimating an increase of the pack-to-melt ratio of 3%, CO2 emissions would be reduced by around 1’000 tonnes per year – because less raw material has to be melted to achieve the same result.
