Biological cycle at home: 7 main themes
Product differentiation - compost
Development of sustainable potting soil based on green compost and other organic recycled materials
• Need for better valorisation of green compost
• Ecological constraints about use of peat
• Increasing consumer awareness for sustainable garden products
Challenge is to maintain the quality of traditional potting soil
Product differentiation - digestate
• AD: input of low value
• Homogenisation & hygienisation
• Products: Biogas methane
Nutrients fertiliser (P)
