Hungary - Central Transdanubia

There are wide range of typical food processing residues from different types of food processing industries that are interesting be upcycled in order to obtain soil improver and meet the Fertilizing Products Regulation. The Hungarian Living Lab will focus on selected food processing residues studying combinations between 1) cereal processing residuals, 2) meat industrial origin rendered animal by-product (especially unexploited biomass animal bone meals from ruminant), 3) industrial fruit processing residues, 4) dairy processing waste (acidic whey), and 5) corn processing waste (corn steep liquor). These are agri/food industrial by-products from which valuable compound biofertilizers can be upcycled, most importantly phosphorus, furthermore replace the chemosynthetic mineral fertilzers with as low as 17% phosphorus use efficiency and restore soil natural balance incl. reparation of the significant phosphorus deficit in soils. In this upcycling context high added value transformation of unexploited biomass converted into new biofertilizer products, perceived to be of greater quality and environmental/climate value with second life and new function that finished product becomes more practical and valuable than what it previously was. In addition, Central European and many other European lands are also significantly climate impacted, especially by drought episodes. To face such issues, novel methods, technologies and market competitive bioproducts needed to increase soil health and productivity, which requires new knowledge and solution generation. Important and objective driven element in this innovation process to create financial and non-financial values, and market competitive benefits for the Users of the new generation innovative bio-fertilizers, which will be investigated in the Hungarian Living Lab as well.The Living Lab operations will have real life technical, legal, economic and environmental aspects in controlled environment while taking into account the current legislation on animal by-products and fertilizers to be in compliance with EU regulatory requirements.

Food processing residues:

meat industrial origin rendered animal by-product (especially unexploited biomass of food grade animal bone meals from ruminant)

cereal processing residuals

dairy processing waste (acidic whey)

corn processing waste (corn steep liquor)

Processes:

4.1.3. The biochar route: optimisation of dry pyrolysis and COMPO-CHAR method

4.1.4. Development and optimization of protein hydrolysates

Key Exploitable Results (KER):

KER4: 3R BioPhosphate fungus biotech processing, agri-biotech processing

Partners:

2 Waste4Soil partners are directly involved in the Hungarian Living-Lab: 3R and BZN. Biochar fungus development and formulation will be done by 3R at the Biofarm Upcycling Centre NUTS 3 HU211 Central Transdanubia region together with farmers to co-create market viable prime results.

On the other hand, BZN will participate in the development of soil improver with biostimulant effect (e.g. phosphate mobilising bacterial strains) by parallel validation work at its own test area in NUTS 3 HU333 Southern Great Plain region, taking care of laboratory and field testing of SI produced, including the monitoring of their effects, and investigating the utilisation of different food processing residues as growing media for large-scale bacteria fermentation.
