Sustainability
OUR JOURNEY
Lime is a versatile mineral that has played an integral part of everyday life for centuries. For over 100 years, MLC has been producing products from one of the richest limestone reserves in the world. Protecting this natural resource will ensure that we can support the evolving needs of society for many more years to come. That is one reason why MLC is committed to conducting business in an environmentally, socially, and ethically responsible manner.
Developing a pathway to a more sustainable future will require setting bold ambitions.
Reliable Quality, Responsibly
The objectives for sustainability at MLC are driven by priorities in three areas: Environmental, Social, and Governance. By promoting stewardship, ethical management, and responsibility in these areas, we can create positive impacts for both people and planet.
