2. THE SUSTAINABLE GLOBAL
GOALS
In 2015, world leaders agreed to 17 goals for a
better world by 2030. These goals have the power
to end poverty, fight inequality and address the
urgency of climate change. Guided by the goals, it
is now up to all of us, governments, businesses, civil
society and the general public to work together to
build a better future for everyone.
“The SDGs are a more radical agenda than
most business leaders yet realized. They
require a shift
from incremental to exponential mindsets and
ambitions; They require to move from our
current focus on the negative impacts of
economic activity to the deliberate generation
of positive impacts.” – Carlo Cella – QualiCal
CEO

3. BETTER LIME, BETTER
BUSINESS, BETTER WORLD
QualiCal vision offers a positive outlook setting
business strategy and transforming LIME
MARKET in line with the United Nation
Sustainable Development Goals (SDGs).
International awareness about climate change is
ever rising. The European Union plans to
drastically reduce CO2 emissions before 2050.
Increasingly stringent regulations appear.
QualiCal wants to play its part in finding
practical solutions.
CO2 emissions are chemically unavoidable in
our industry: around 70% of the total CO2
emissions are so-called process emissions,
originating from the decarbonisation of the
limestone when it is transformed into lime. We
have to take our responsibilities and find
answers to prepare the future, in order to
protect the environment and stay competitive.

4. SUSTAINABILITY PROGRAMM
Sustainable development and responsible business practices are some of the core values that guide
QualiCal.
We recognize that today’s decisions can have long-term consequences, and we need to proactively
manage our operations and resources to ensure a beneficial and sustainable future for our employees,
customers, community members and stakeholders.
QualiCal is managed with a long-term perspective. We invest for the future, with an emphasis on
attracting and retaining the best people, value-creation and sustainable development. Our sustainability
programs facilitate the balanced pursuit of economic performance, environmental stewardship and
social responsibility.

9. 9 INDUSTRY, INNOVATION AND INFRASTRUCTURE
 Build resilient infrastructure,
promote inclusive and
sustainable industrialization
and foster innovation.
 A functioning and
resilient infrastructure is
the foundation of every
successful community.
To meet future challenges,
our industries and
infrastructure must be
upgraded. For this, we
need to promote
innovative sustainable
technologies and ensure
equal and universal access
to information and
financial markets. This will
bring prosperity, create
jobs and make sure that we
build stable and
prosperous societies across
the globe.

10. 12 RESPONSIBLE CONSUMPTION AND
PRODUCTION
 Ensure sustainable
consumption and
production patterns.
 Our planet has provided
us with an abundance of
natural resources.
But we have not utilized
them responsibly and
currently consume far
beyond what our planet
can provide. We must learn
how to use and produce in
sustainable ways that will
reverse the harm that we
have inflicted on the
planet.

32. #ACTION NOW
SUSTAINAIBILITY IN
ACTION

33.  Sustainable Resource Management
QualiCal is committed to the efficient use of the natural resources that we are privileged to use. Consistent with our Operational Excellence and sustainable business model, our
plants operate to optimise our operational performance with a minimal operational footprint.
We work closely with local authorities to meet their environmental regulations and to ensure there is as little disruption as possible. This enables us to fit into local environments and
communities quickly and easily.
Just as important to us is how land is used after our operations have stopped. We undertake studies and conduct careful planning to ensure land is reusable and productive for the
local communities
 WATER
Water is an essential component of our mining and mineral processing. We understand the finite quality of this vital resource and work diligently to ensure that water is managed in a
way that is cost effective for the business as well as sustainable for the community and environment.
QualiCal strives to optimize our water balance by conserving and recycling our process waters in closed loop systems. In arid regions, storm water management represents an
opportunity to put natural precipitation to productive use. Many QualiCal locations operate rainwater collection systems to supplement recycling efforts, with an objective to minimize
volumes drawn from the local aquifer. We are equally committed to control effluent water quality and diligently monitor and manage permitted discharge to meet local regulations.
 Energy Consumption
Our objective to improve our energy efficiency is consistent with our culture of continuous improvement and Operational Excellence. QualiCal plants operate to minimize energy
consumption, including renewable energy sources such as hydropower and bio-gas to help preserve finite hydrocarbon resources. Several plants utilize exhaust gases to pre-heat
dryer circuits for additional energy efficiency.
 Land
Our objective is to balance economic objectives with environmental conservancy, in a manner that ultimately returns mined land to an ecologically appropriate landscape. We employ
three-dimensional mine modeling to plot unique geologic features in a way that maximizes the land’s productive potential while minimizing waste. Data from the modeling process is
compiled in a mine plan that provides technical guidance for the safe and efficient extraction of the raw ore.
Each deposit plan is continuously reviewed and adjusted to ensure the extraction and beneficiation processes are aligned with customer requirements. The mine plan provides quality
assurance information to our customers and validates our performance as a sustainable supplier.
 ENDURING LOCAL PARTNERSHIP
QualiCal strives to be the ‘neighbor of choice’ for local communities. Locally formulated community action plans are one way to be a respected and contributing member of the
community. Action plans can be as diverse as our organization; ranging from financial support for heritage projects, to construction of a regional school, to providing safe drinking
water for drought-stricken communities.
We also recognize that the economic and social viability of our communities is an important part of our sustainable performance, and regard local spending to source goods and
services as an investment in our future. We’re proud to play a role in the local economy by being a sustainable source of employment, cash flow and revenue for the benefit of our
communities and the surrounding regions.
 GOOD NEIGHBOR POLICY
QualiCal sustainability programs include metrics and resources to minimize the potential impacts of our operations on surrounding communities. Each QualiCal plant undergoes a
comprehensive environmental audit and comparative impact study to identify potential sources for concern and proactively take corrective or mitigating action.
We accomplish this by using cleaner alternate energy sources and installing control devices that reduce emissions. We also monitor our operations to minimise noise, vibration and
visual impacts upon our immediate neighbors and surrounding communities.

initiatives and is achieved through programs that promote and reinforce best
practices for our employees, contractors and visitors. We encourage best
practices and celebrate the achievements of our team in delivering on this core
company value.
 “Going for Zero” is QualiCal’s worldwide safety improvement program with the
objective to eliminate all injuries from our business. Going for Zero takes a
comprehensive approach to safety that combines global safety standards and
behavioral training with peer practice to make every employee a safety leader.
The goal is to increase awareness of potential risks in a work environment
where each employee feels responsibility for the safety of their colleagues. As
safety is QualiCal’s number one priority, every QualiCal employee will undergo
Going for Zero training
