Technology offer : Horticultural pot made from seaweed

Technology's description

Bio-sourced materials represents an important opportunity for the horticultural sector and more spécifically for fertilization purpose.

This innovation is about new biodegradable materials made from seaweed, able to deal with plastic issues and fertilization intakes. The technology patented by the Rennes university and CEVA (Center for study and promotion of algae) provides more inputs than tradtional horticultural pots thanks to its components (végetal fiber and algae).

This material provides more nutrients (Potassium, nitrogen, phosphorous, sulphur) and a better inputs' absorption.

The vegetal fiber and algae conception, with seaweed pot allow strong roots that can spread through the pot and the nitrogen charge is also better compared to other fertilizers.
