  As the population of the Earth is constantly growing it generates an unmet demand for protein, which is an urgent problem. The protein extraction process is a potential solution, which offers high-quality plant protein suitable for animal and human nutrition at a favorable price. The process used within our project produces green juice from the green alfalfa biomass through pressing. After the coagulation of protein from this green juice, the by-product is called DPJ (Deproteinized Plant Juices) or brown juice. Our preliminary results match the international literature, namely that brown juice take up as much as 50% of the fresh biomass in weight. To utilize this by-product is a crucial part of the process to make it environmental-friendly and financially viable as well. The examined brown juice samples came from a small-scale experiment of alfalfa varieties carried out in the experimental farm at the University of Debrecen. According to our preliminary results, brown juice has high macro- and micronutrient values, furthermore, it has a potentially high amount of antioxidant compounds. The study highlights that brown juice is suitable as an ingredient in microbiological media, in plant nutrition as a supplementary solution, for feedstock and for preparing human food supplements or functional foods. The potential utilization of all biorefinery products makes it a very appropriate technology for today’s challenges.

  The development of the new economy in Hungary involves a complexity of economic and social processes. The sectoral structures and territorial location of the industy and the higher education show significant inequalities. Capital city concentration, low level of research orientation and insufficient linkages with industries are the most important barriers of the development of higher education and reindustrialization. The regional and cohesion policies need strong relations between economic restructuring and higher education development. The paper focuses on demonstrating the regional differences in these fields in southern and eastern Hungarian regions.

  The control of our relationship with our environment is one of the greatest challenges of the 21st century. This has an effect on the economic and social processes and the human activities. All of these are included in a new developmental strategy: the strategy of sustainable development.
  The strategy of sustainable development prevails by the new technologies and it is realized on high-tech level as the fermentation manipulation of organic materials, biogas production and production of “green” electric current. 
  One of Europe’s largest bioreactors has been established in Nyírbátor in Hungary at first (chief executive: Mihály Petis).
