PYRAGRAF

Optimising agricultural and forest residues and waste management to increase renewable energy incorporation and reduce the carbon footprint of agricultural and forestry systems is currently essential and goes hand in hand with improving the resilience and sustainability of remote regions. The PYRAGRAF project will develop a mobile and integrated unit to demonstrate the pyrolytic conversion of forestry and agriculture crops residues and wastes into added-value products. The concept for this mobile demonstration system at TRL 7 is composed of 3 main modules: 1) a solar-assisted gasifier burner, 2) a biomass dryer, and 3) an integrated pyrolysis reactor thus producing sustainable products using renewable sources (solar energy and biomass). 

This multi-product approach includes two main product categories - biochar and wood vinegar ecosystems services; and energy applications of upgraded pyrogas and bio-oil – that can be integrated with different agriculture applications, thus enabling to reduce GHG emissions and the use of fossil resources and in agricultural practices; improve the development of rural areas, among other benefits. Field demonstrations with the involvement of local stakeholders inside and outside of the project will be conducted in 3 countries (PT, DE and TR) to demonstrate the operation of the mobile pyrolysis unit and evaluate the fertilisation and biopesticide potential of biochars and wood vinegar in different soils/crops and climate conditions. The pyrogas and bio-oil will also be evaluated as energy carriers for dual-fuel engine sand fuel cells as biofuel to be used in local agriculture or forestry practices.
