Wealth from Waste: A Review of Garbage Enzyme

2021

Water Pollution has become a major problem with increasing urbanisation and rapid industrialisation. Despite the abundance of water, pollution causes the water to be less useful and more harmful to health, environment, and life on our planet. In past few years, many researchers have focussed on use of biological & physical treatment methods that are cost-effective and cause no harm to the environment instead of chemical methods. The aim of the present work is to study the effect of organic solid wastes in the form of orange peels, marigold flowers, and neem leaves on domestic wastewater treatment. Eco-enzyme solutions were prepared using Dr. Rosukon’s method from the wastes mentioned which involves mixing jaggery along with the wastes and water in the ratio of 1:3:10. The eco-enzyme solution was then allowed to be prepared through 90 days of fermentation process. The three eco-enzyme solutions – after 10 days of filtration – were then mixed with domestic wastewater samples individua...

Garbage enzyme is a fermentation product. It is prepared from organic waste, water and brown sugar. It is prepared by fermentation of jaggery, organic waste and water mixture with the ratio of 1:3:10. It takes a period of three months. Bio catalytic activity of enzyme shows that it contains protease, amylase and lipase activities. Enzyme is capable of degrading protein, starch and lipids present in wastewater. This study assesses the effectiveness of different types of garbage enzymes prepared with different raw materials such as fruit waste, eicchornia and bagasse. Garbage enzyme solution is added directly in wastewater with different proportions in order to treat it. However it is observed that, there is no reduction in the Chemical Oxygen Demand (COD) of the wastewater. Hence another method is used which is termed as enzyme immobilization method. This method is applied to treat synthetic wastewater prepared in the laboratory. Sodium alginate beads are used for enzyme immobilisation. The immobilised enzymes are used and tested for treatment of synthetic wastewater. Study revealed that, the enzymes prepared using fruit waste found to be most effective for reducing COD up to 80%. Enzyme prepared using eicchornia found to be most effective for reducing Biochemical Oxygen Demand (BOD) up to 48% and Ammonia Nitrogen reduction is up to 77%. Enzyme prepared using bagasse found to be most effective for reducing phosphate up to 82%.

Garbage enzyme is obtained by fermenting fruit and vegetable wastes. This alternative method of biological recovery of organic waste may provide a solution to waste minimization and reduction since a large proportion of municipal solid waste consists of food waste. A study was conducted to assess the implementation of garbage enzyme making and usage as an initiative to reduce the amount of municipal solid waste generated by a hawker community. It was found that practical values, communal spirit and awareness of environmental consequences were among the factors that encourage the practice of garbage enzyme making, while ignorance, time and convenience factors hinder garbage enzyme making and usage. Taking these factors into consideration, municipalities could promote garbage enzyme as a viable method in reducing the amount of MSW generated.

ROLE OF ENZYMES IN WASTE MANAGEMENT, 2020

Nowadays environmental pollution (including water, air, and soil compartments) has reached elevated levels to be of great concern for humans and other living organisms. Therefore several research efforts have been dedicated to find effective, eco-friendly, and possibly low-cost tools to mitigate the pollution and to clean up and restore polluted environments. In this context, enzymes play a vital role and are potent and specialized catalysts able to transform a variety of compounds including environmental pollutants. Moreover, their catalytic capability is so high that also recalcitrant (ie, less or not transformable, at all) compounds can be converted to safer or innocuous final products. Due to their peculiar properties, enzymes have been considered a good alternative to traditional, non-biological cleanup methodologies. Several examples are available in literature on the use of enzymes for the transformation of single or complex mixtures of pollutants. Attempts at their direct utilization for the recovery of polluted bodies were also addressed as well.

One of the organic waste processing technologies is Eco Enzyme. Eco enzyme is a complex solution of light to dark brown color, which has a fresh sour aroma. Organic waste, in the form of fruit peels, unused fruit flesh, and vegetable pieces, is collected in containers/barrels and then mixed with molasses/brown sugar and water with a certain dose. The recommended dose for the ratio of molasses: organic waste: water is 1:3:10. The fermentation results produce environmentally friendly enzymes and other beneficial elements for agriculture. This study aims to determine the nutrient content of P2O5, K2O, and the C/N ratio of eco enzymes derived from various organic materials. This study used a non-factorial, completely randomized design (CRD). This study used 6 treatment combinations consisting of: P1 = Musa paradisiaca L Boobs (1.5 kg) + Tithonia diversifolia Leaves (1.5 kg); P2 = Musa paradisiaca L weevil (1.5 kg) + Terminalia catappa leaves (1.5 kg); P3= Musa paradisiaca L Weevil (1.5 ...

A multipurpose solution for domestic and agricultural uses has been identified as "garbage enzyme solution". It is a fermentation product of jaggery, kitchen trash, and water in a proportion of 1:3:10. The effects of dilutions (5 percent to 75 percent) of waste enzyme, which can be employed for a variety of purposes, are investigated in this study. The pH of the garbage enzyme solution (GES) was discovered to be between 4.5 and 6.5.It is a multi-component preparation that has been described as multipurpose solution. Garbage enzymes have been used as a cleanser, deodorizer, insect repellent, soil conditioner, insecticide, and fertiliser as per the study.. The main findings showed that GE was acidic in nature, with citric acid being a significant component. Citric acid, sugars, proteins, alcohol, and enzyme activity such as protease, amylase, lipase, and papain were found in biochemical analyses of GES preparations. As a result, this investigative support the use of GES as a multipurpose liquid. Garbage enzyme is an environmentally beneficial alternative to commercial cleaning products that pollute water and harm the environment.

Waste and Biomass Valorization, 2014

ABSTRACT According to Food and Agricultural Organization (FAO), one-third of food produced globally for human consumption (nearly 1.3 billion tonnes) is lost along the food supply chain. In many countries food waste is currently landfilled or incinerated together with other combustible municipal wastes for possible recovery of energy. However, these two options are facing more and more economic and environmental stresses. Due to its organic- and nutrient-rich nature, theoretically food waste can be converted to valuable products (e.g. bio-products such as methane, hydrogen, ethanol, enzymes, organic acids, chemicals and fuels) through various fermentation processes. Such conversion of food waste is potentially more profitable than its conversion to animal feed or transportation fuel. Food waste valorisation has therefore gained interest, with value added bio-products such as methane, hydrogen, ethanol, enzymes, organic acids, chemicals, and fuels. Therefore, the aim of this review is to provide information on the food waste situation with emphasis on Asia–Pacific countries and the state of the art food waste processing technologies to produce enzymes.
