DISAB prevents dust build-ups from happening
by cleaning and removing dirt, dust and
spillages using vacuum based technology with
a powerful suction ability. Our mobile, semi-
mobile, and stationary machines and system
solutions help facilitate good housekeeping to
increase the safety of your workers.

linked to a certain type of technology or product. Thus,
a proper technical assessment is fundamental, otherwise
benchmarking runs the risk of becoming a purely statistical
exercise, of which the added value for energy efficiency
optimisation purposes might be questionable.
Conclusion
By increasing the use of AFs and improving energy
efficiency, the cement industry has proven in the past
decades that sustainability and the simultaneous reduction
of operational costs can go hand in hand. Energy reviews
are one of the most time- and cost-effective ways to
uncover potential energy savings in cement plants and
thus reduce CO2 emissions even further. Potential energy
savings are plant specific and some trade-offs must
be negotiated. Therefore, recommendations must be
technically supported and customer oriented. Numerous
energy reviews have shown that practically all plants
reviewed showed potentials for improvement with regard
to energy demand and, consequently, reducing energy
costs. In order to reach the highest technical level, the
correct operation and maintenance of state-of-the-art
equipment, tight control of the whole process, and careful
selection of fuels and raw materials is fundamental. A
detailed review can always help to uncover improvement
potentials, which was also the case in plants that were
well-operated and maintained, and where major energy
efficiency measures had already been identified and
implemented.
