Technologies for the production of biofertilizers : trends and opportunities

Abstract

Japan, Europe, the USA, Korea, India and Brazil are among the most prominent countries in the field of patent publications for waste management for the production of biofertilizers. This assertion is ratified by a total of 1,952 patent publications (100%) associated with the classification of basic chemical products, fertilizers and nitrogen compounds, plastics and synthetic rubber in primary forms, followed by classifications associated with the manufacture of machines. It is worth noting that in addition to the strong presence of the fertilizer segment, there is a presence of classifications associated with the medical and dental, pharmaceutical, food, oil, transport, construction, cosmetics and beverages sectors. A more detailed analysis of the patents thus verified will make it possible to identify relevant technologies, incremental innovations, market niches for performance and technological maturity level, especially when compared to the number of articles published per country.
