Waste Reuse in a food establishment for the production of organic fertilizer in Manaus - Amazonas

Abstract

Organic waste has been a threat to society and the environment, both by the amount generated and the inadequate treatment. Seeking solutions to these wastes, composting becomes an efficient process through accelerated biodegradation. The present study aimed to analyze the reuse of organic waste generated in a food establishment in Manaus-AM. The quantitative methodology presented two steps, weighing for three (3) weeks daily, (i) the waste generated in the kitchen and (ii) discarded by consumers, in addition to the total compost generated by the compost, as a basis for treatment of this material, as way of minimizing the amount of these wastes, analyzing the productive activities of this establishment. Given the results obtained it was observed a disposal of almost 30 kg / week, which if estimated, can reach a value of 0.5 tons / year, for each type of disposal evaluated, totaling a value that can reach 1 ton of organic waste disposed of by this small food establishment. Analyzing the composting process, the data show that there is a reduction in the amount of materials generated, due to their transformation into organic fertilizer, obtaining 50% of the total value produced from the waste, thus indicating a solution to the problems arising from the incorrect disposal of waste. organic matter, which is close to 54% of this waste generated in Brazil. In addition, currently about 1.3 billion tons of food is wasted and there are on average about 815 million hungry people in the world, proving to be an alternative of economic, social and ecological viability.
