Strategic report
Controlling our dust emissions
Dust emanates across the entire production value chain - raw
material handling, limestone crushing, kiln processing, clinker
production and storage, finished cement grinding and power
utilities, cement bagging, and so on. We strive to minimise
the release of dust emissions into the atmosphere and ensure
compliance with both legal requirements and international
standards. Dangote Cement kilns have been provided with
state-of-the-art dust abatement equipment, including bag house
filters and electrostatic precipitators. The state-of-the-art design
combined with routine control and preventive maintenance
allows us to effectively control our dust emissions and maintain
the average dust emissions at the stacks in a range well below
the typical regulatory threshold limits of the countries where
we operate.
Compared to 2020, the dust emission in 2021 from some of our
plants reduced as a result of improved routine maintenance and
installation of a new dust abatement system. The dust emissions
from our Ibese, Ethiopia, Senegal and Tanzania plants reduced
year on year while other locations emitted more specks of dust
in 2021 compared to 2020 owing to faulty bag house and filters
issues which are now being addressed.

Implementing efficient water
management system
Water is fundamentally a local resource and its sustainable
management requires an understanding of the specific context
and drivers in each location. We know that just 2.5% of the earth's
water is freshwater and that a significant rise in water demand also
accompanies Africa's fast-growing population and urbanisation.
Water is gradually running out in several regions around the world
due to the scourge of climate change leading to dry up in some
regions, rain pattern and frequency distortion, and insufficient
rainfall that has resulted in severe water scarcity with heightening
socio-economic crisis.
Although our operations do not require large quantities of water
in comparison with other sectors, we are committed to reducing
the amount of freshwater utilised in our business activities.
On an operational basis, our efficient water management
system involves periodically measuring our operational water
footprint and making effort at reducing freshwater withdrawal
and consumption through water recycling and storm water
management. We understand that our responsible use of water
will ensure more availability for the local communities, especially
in those regions that are characterised by endemic water scarcity.
Rehabilitation of quarries and biodiversity
The first step in cement production, the extraction of raw
materials from the earth's crust - inevitably has an impact on
the surrounding natural and social environment. However, these
impacts can be successfully mitigated through the development
and implementation of a quarry rehabilitation plan which can
contribute to bringing significant environmental and social
benefits to the environment around operations. At Dangote
Cement, we understand that companies that minimise ecological
footprint and ensure the preservation of the natural capital as well
as the welfare of host communities are more sustainable and give
a competitive advantage.
To minimise impacts of quarry activities in 2021, Dangote
developed a quarry rehabilitation plan that would address
stakeholder expectations and be aligned with, or leverage from,
the stakeholder view, experience, culture and customs. Through
the partnerships, resourcing and engagement of stakeholders,
a monitoring plan is developed ensuring the documentation
and measurement of progress and performance against
the objectives.
In 2021, we increased the numbers of trees planted across
our operations to reduce our carbon footprints and negative
environmental impacts in host communities. Over 510,636 trees
were planted across 9 countries of operation, including Nigeria
(Gboko, Ibese), Congo, Ethiopia, Ghana, Senegal, South Africa,
Tanzania, and Zambia, accounting for an increase of over 41,000
trees from the previous year. The tree planting campaigns are part
of our biodiversity restoration and measures towards combatting
Climate Change and global warming, leveraging the carbon sink
potentials of trees.
