Production and Characterization of Eco Enzyme Produced from Fruit and Vegetable Wastes and its Influence on the Aquaculture Sludge

Abstract

The high composition of food waste in municipal solid waste production is one of the most critical environmental issues since the decomposition process produces and releases carbon dioxide and methane into the atmosphere and causes a greenhouse effect. Therefore, to minimize the composition of organic wastes in the landfill, this study was conducted to characterize the eco enzyme produced from the fermentation of fruit waste. Then, the treatment of aquaculture sludge will also be determined to examine its applicability. The effectiveness of the eco enzyme on sludge treatment was experimented based on the different dilution factors of the eco enzyme (5 %, 10 %, 15 %) for 10 days (Batch process). The results showed that the eco enzyme possesses Protease, Amylase, and Lipase. Meanwhile, the results of the treatment process showed the enzyme solution (10 %) was found more potent and economical in treating aquaculture sludge in which resulted in a reduction of 89 % of Total Suspended Solid, 78 % of Volatile Suspended Solid, 88 % of Chemical Oxygen Demand, 94 % of Total Ammonia Nitrogen and 97 % of Total Phosphorus. Eco enzyme produced from the study has effectively acted as an environmentally friendly solution to reduce the composition of food waste in solid waste generation and has the potential to be applied in the wastewater industry.
