THE EARTH IS NOT A GIFT FROM OUR PARENTS, IT IS A LOAN FROM OUR CHILDREN . JJ. Audubon, ornithologist, naturalist and French painter, 1851.
SELLING RECYCLED AGGREGATESMAC Insular is a company engaged in the treatment of construction and demolition waste whose main aim is the minimal waste, or in other words, waste recovery.
Therefore, the construction and demolition waste received in the plants are subjected to a cleaning, grinding and screening process . The cleaning stages to obtain recycled aggregates consists of the separation of magnetic metals, aspiration of unsuitable items, manual sorting and finally a ballistic separation to completely purge the material.
As a result of the construction and demolition waste treatment, the following sizes of recycled aggregates are obtained:
These recycled aggregates bear theCE Marking according to the following regulations:
