The ecological plant substrate ROTOPOR®

Natural solutions for horticulture and landscaping

Future viability and sustainability

due to its outstanding energy balance

Energy balance refers generally to the sum of the energy consumed in the production and processing of a product.

Simple mining and very low transportation costs deliver the Natural expanded silicate on energy efficient way to the refinement process. This in turn requires less energy because what would have been an energy intensive operation, the "expansion" was already done by nature thousands of years ago. Therefore, cleaning, drying and sieving are sufficient to produce valuable lightweight aggregates from Natural expanded silicate. The largely packing free delivery in silo trucks or big bags completes the excellent energy balance of ROTEC®-lightweight aggregates perfectly.
