Main reasons for energetic use of biomass (PROS)
1. Environmental 2. Economic and policy reasons
Carbon neutral Replacement of oil
Renewable Reduction of the energy dependence of the region
Helps to save the rural landscape and regional features
Increase regional employment in rural areas

Eco-holistic evaluation is a new idea which combines traditional holism with an eco-centric view.
We invite you to evaluate the biofuel production in a eco-holistic
way

Is production of bio-fuels really environmentally sound?
(&CONS) In the short run only intensive
(industrial) systems are economically feasible (only big farms getting subsidies 500-5000 hectares )
Production with high industrial input, small positive energy balance, a lot of chemicals used
Mainly monocultures, reduced agro-biodiversity
GMO use is stimulated

The environment sustainability depends on the production features.

Is it possible to create and actually operate a sustainable social-economical-ecological systems or not?
Ecoflex model
With the help of the okoflex model we try to frame the rape oil manufacture of Szedres into the triad of economy, society and environment.
Ecoflex is a type of eco-agricultural model. The model’s originality is that it integrates the rape oil pressing
manufacture into the ambient agricultural structure.The stock can be produced in a 50-60km zone. (Minimizing transport distances, reduces environmental charges and
also reduces transport costs.)
