Calcareous stone of sedimentary origin is an abundant natural resource in our country, a local material, existing in almost all our regions. With a responsible extraction and restoration system, it requires little energy to be put into its architecture. It is a naturally consolidated material subjected exclusively to cutting processes.

 

‘Immersed in a process of continuous improvement, our extractive and processing activity has been certified in ISO 14001 since 2005. In 2019 we gained recognition from the ministry for reducing our emissions’

 

Extractive System

In our Albamiel calcarenite stone quarry, the blocks are cut dry, avoiding water consumption, through the Horizontal Extraction system that minimizes risks and maximizes the utilization of the resources.

This extraction system has been part of the know-how of our team for more than 30 years and can be applied in any authorized extraction area, to avoid transport costs and emissions. If you are interested in implementing a sustainable extraction system you can arrange this service with us here.

Responsible Use of Natural Resources

For other primary and secondary cuts made with water, it is part of a closed circuit in which it is filtered and decanted and reused, not leading to any discharge to the public channel.

The electrical energy used for production processes is exclusively green, obtained from inexhaustiblenatural sources, with 20% internal production.

Restoration and Offsetting

Our environmental awareness has led us to include the restoration of the quarry as another stage in the extraction process, both being carried out simultaneously.

The aim is to facilitate the regeneration of the soil and the regeneration of the landscape, since by not generating soil pollution with our extractive system, it is easier to return it to its original state. We add organic matter, seeds and native plants, to any stone remnants that, in addition, will generate carbon sinks to offset our already low current emissions.

Measurement and Reduction of CO2 Emissions

Following the measures put in place to reduce our CO2 emissions, (measurements and reductions certified by the Ministry for the Ecological Transition) in 2019, we achieved 70% less GHG emissions than the same amount of silica sand (Ecoinvent 2018 data), in pursuit of, in our case, an end product directly on-site.

Industrialized Construction

The on-site installation, following the ad hoc production for each project generates no on-site waste, being carried out dry, with no need for large contributions of water as with concrete or subsequent finishes.
