Securing raw materials for green urban development
Volcanic raw materials have played an important role in the production of roof, tree and lawn substrates for 30 years
for high-quality substrates.
Without the use of these raw materials, it is difficult to comply with the legal rules for the production of vegetation products.
The deposits in Germany / Eifel cannot possibly cover the increasing demand for high-quality lava in Europe.
The constant dry periods in summer mean that transport on the rivers (Rhine) is no longer possible all year round.
In order to counteract future shortages, CALAVA SL on Gran Canaria has developed high-quality raw materials for the production of substrates.
In ship sizes between 4,000 tons - 7,000 tons we deliver to the
Channel coast and various North Sea ports.
Another advantage of CALAVA is the high quality and
the availability.
