This book describes the results of the research of the project
entitled Phosphorus Renewable Raw Materials: A Resource Base for
the New Generation of Fertilizers' attributed to the National
Center for Research and Development of Poland. This book is divided
into three chapters that are assigned to different stages of the
project undertaken by different R&D institutions. The concept
and possible options of valorization of waste biomass, such as
bones, fish bones, and ashes originated from the incineration of
sludge from a waste-water treatment plant from the tertiary stage
of biological treatment as resources of phosphorus were described
by the team from Wroclaw University of Science and Technology. As a
method of by-products valorization, the solubilization process was
proposed. Two strategies were proposed: Ex-situ and in-situ. The
in-situ manner resulted with suspension fertilizer with a low
concentration of P2O5 while ex-situ gave the possibility to obtain
two solid formulations with the high content of P2O5. All of them
could be used in agriculture and horticulture as granular
fertilizers or as substrates. The different content of P2O5, as
well as other nutrients in obtained formulations, were described as
an effect of utilization of different raw materials as well as
various additional substances such as binders necessary for the
stability of final formulations. What is more, the efficiency of
obtained formulations was strongly related to the kind of
microorganism used as an 'activator' of unavailable phosphorus,
which was discussed in details. The technology of production for
biofertilizers in pilot-scale was described by the Institute of New
Chemical Synthesis in Pulawy with the following issues underlined:
Design of installation to produce fertilizers based on renewable
raw materials; plant construction and production of the product;
and preliminary economic analysis. The University of Warmia and
Mazury in Olsztyn described the utilitarian properties of new
fertilizer formulations that were evaluated in field tests with
special attention to granular and suspension biofertilizer. In that
chapter, the major results of the agronomic evaluation of new
suspension and granular phosphorus biofertilizers from secondary
raw materials (sewage sludge ash, animal bones, and animal blood)
were presented. Biofertilizers contained Bacillus megaterium or
Acidithiobacillus ferrooxidans bacteria. New bioproducts were
tested in field experiments in reference to traditional commercial
phosphorus fertilizers (superphosphate, phosphorite, etc.). The
research confirmed that phosphorus biofertilizers from renewable
raw materials were similar to commercial fertilizers in terms of
their crop-enhancing efficiency and did not reduce yield quality
and quantity.
