Multi-purpose crops and creativecombinations of valorisation

Why multi-purpose crops?

Multi-purpose crop: Multi-product crops

Multiple land-use Combination of VTs1, different approach to

bio-energy and bio-based products( unidirectional)

Implementation on-farm

1VT = valorisation trajectory

3/19

How can a farmer in Flanders use his/her

crops for multiple purposes, by combiningdifferent valorisation trajectories amongstwhich bio-energy and bio-based products?

Research question

Integrating Food Feed - Fuel Fibre functionsHow can typical crops contribute to the diversification of

agricultural activities?

6/19

First step in research:

line up different VT of crops in Flanders in a

comprehensive way

look for similarities between different crops

Create a Generick scheme Innovative use of existing crops

Assess the potential use of new (newly introduced) crops

In general: logistics, cultivation techniquerelated, ecological

Specific: co-fermentation, combustion,feed

11/19

1. Variable production stochasticity,

2. Uncertain parameters assumptions

3. Production theoretical optimisation1 without opportunitycosts

4. With opportunity costs : linear programming with datafrom representative farms+ uncertainties via sensitivityanalyses

5. Identification of CFS by. sensitivity analyses

1cultivation costs versus return on farm. The loss of benefits due to thereplacement of other crops by Misc. is not taken into account.
