Mibau Stema Group

Sustainability is more than a buzzword for us

We supply a comprehensive range of aggregate products and solutions, meeting the needs of the construction, asphalt, and concrete industries globally.

Our commitment to reducing our carbon footprint covers all operational levels.

We focus on responsible water with rainwater collection, enhanced waste management and of course the use of renewable energy

We have an extensive ecological restoration plan that creates extended habitats for native flora and fauna while even exceeding national guidelines. 

To reduce quarry noise and quarry dust, we work with all local and governmental agencies and have taken several concrete steps to lessen the impact of the noise emission that controlled ordinances can cause.

Transporting stone, aggregates, and gravel is energy-intensive and requires sufficient space for high-volume loads. For these reasons, shipping has been the go-to solution for years.

Sustainable aggregate production requires constant supervision and monitoring. We adhere to various standards and norms to help foster more climate- and environmental protection. 


We have a special bond with all the land we manage and a solid commitment to its healthy and sustainable future
