From waste to resource: Interreg 2 Seas Horti-BlueC is organising 4 webinars on the valorisation of 5 local byproducts into building blocks for more sustainable growing media in horticulture.

How feasible are those valorisation chains, both technically, economically and logistically? Which processing or treatment is necessary to convert the waste streams into valuable resources for replacing peat, coir and mineral wool? Do these building blocks truly contribute to effective new growing media blends for strawberry and tomato plants, with reduced fertilizer and chemical crop protection product use?

These questions will be addressed in the four webinars. The first three will take place this Spring and the fourth webinar is planned for Fall 2021. Check the calendar for the announcement and registration link of the other Horti-BlueC webinars.

Horti-BlueC webinar 2: May 20th 14:00-15:30 CEST (13:00-14:30 BST)

In this second webinar, the conversion of shellfish waste into chitin will be discussed. Chitin can be used as a renewable N fertilizer and microbial stimulant when applied in growing media for soilless cultivation. For more information, watch this short video.
