Production of Biofertilizer and Composting from Solid Organic Residues of a Restaurant: A Case Study 

2. Academic of Environmental Engineering, Paragominas, Brazil

Abstract: Biofertilizer is the liquid effluent derived from the fermentation of organic matter. It is rich in vitamins, enzymes, soil-nourishing antibiotics and, furthermore, protects and provides resistance to plants from the attacks of external predatory agents. Thus, the objective was to analyze the domestic composting process, through the influence of environmental and chemical parameters (relative humidity, temperature, precipitation and pH) obtained by way of the decomposition of organic, animal and vegetable matter coming from restaurants. The collection of food waste occurred on March 8 and 22, 2019, rainy season, in a restaurant located in the city of Paragominas - PA. The method employed in the research was the inductive with quantitative and qualitative nature, and with experimental procedure. The data obtained were statistically treated with the application of Pearson's Correlation. The analysis of these data indicated that there is production of biofertilizer and organic fertilizer by maturation of organic compounds; the pH was revealed to be from slightly acid to acid (4.0 to 5.0), then, applicable as an irrigating liquid and of good fertility. Therefore, it is of major importance to recycle organic food waste as an alternative solution for its accumulation and incorrect disposal in the environment.
