Development of Anaerobic Biodigesters for the Treatment of Municipal Organic Waste and Biogas Generation for Use as Energy Source

AbstractTo tap the organic waste generated onboard cruise ships is a very promising approach to reduce their adverse impact on the maritime environment. Biogas produced by means of onboard anaerobic digestion offers a complementary energy source for ships’ operation. This report comprises a detailed presentation of the results gained from comprehensive investigations on the gas yield from onboard substrates such as food waste, sewage sludge and screening solids. Each person onboard generates a total average of about 9 kg of organic waste per day. The performed analyses of substrates and anaerobic digestion tests revealed an accumulated methane yield of around 159 L per person per day. The anaerobic co-digestion of sewage sludge and food waste (50:50 VS) emerged as particularly effective and led to an increased biogas yield by 24%, compared to the mono-fermentation. In the best case, onboard biogas production can provide an energetic output of 82 W/P, on average covering 3.3 to 4.1% of the total energy demand of a cruise ship.

Waste Gasification

One of the abundant energy source in Indonesia is organic waste in the form of leafs and branches which is widely avalilable in homeyard. It can be utilized as alternative energy source by gasification process. The objective of the study was to know the influence of raw material and AFR to the characteristic of organic waste gasification process. The raw material used were leafs and branches of melinjo (gnetum gnemon) which obtained from homeyard of inhabitant in Sidomoyo village, Godean sub-district, Sleman Regency, Indonesia. Before being gasified, it was prepared for proximate analysis in laboratorium. The gasification begins by feeding the raw material to the reactor with variation of 100% leaf, 100% branch, and 50%-50% leaf and branch. The gasification process was occured in reactor for one hour, and syn gas which produced has been analized to know the composition of it. Result shows that raw material have influenced the characteristic of gasification process. The highest heating rate was occured for gasification process of 100% leaf and AFR 0.5, which it gas has burned after 25 minuted process in oxidation temperature of 650 0C, reduction temperature of 350 0C, and pyrolysis temperature of 240 0C.

Detailed Explanation

This paper summarised different methods used for the electrical power generation using microorganisms in MFC. In the past decade, Microbial Fuel Cells (MFC) attracted many researchers due to their ability to convert organic waste into electric currents by the usage of microorganisms. It has been developing as a great source of renewable energy. This device makes use of simple cathode and anode compartments and a separating membrane. This can be efficiently used for power generations and wastewater treatments. Microbial electrolysis cell (MEC), a type of MFC is also used in generating Hydrogen energy from various biological matters. The performance of MFC totally depends upon the nature of microorganisms, electrodes selected, and the separating membarane used. MFCs serve as a sustainable and alternate energy source to reduce the pollution caused by industrialization. In this review, a detailed explanation about MFC and different ways of generating bioelectricity and hydrogen from wastewater treatment are explained.

The Government

Abstract The government focuses on converting garbage into energy, such as in Cilacap, that waste is processed into Refuse Derived Fuel (RDF). Compared to organic waste, a material with high calorific value fractions such as plastic is a potential energy source. Of contrast, organic waste dominates the waste composition in Indonesia. This study aimed to look into the waste composition in Cilacap as a resource of RDF. This is descriptive research that uses quantitative approaches. Organic waste dominated composition by 53,14%, according to a survey of 100 respondents. The percentages of plastic waste, paper, textile, and rubber/leather are 28,46%; 16,09%; 0,8%; and 0,42%; respectively. People who generate more organic waste are more likely to engage in social activities, have no yards and have no livestock. Furthermore, buying too much food and regularly leaving meals on the table may increase organic waste production. The calorific value obtained from the data is 3.735 kcal/kg. Knowing the theoretical calorific value of waste composition in Regency gives an overview of economic potential and research into appropriate policy recommendations for the government.

Batch Digester

Abstract Cow manure, chicken manure, and organic waste are solid wastes that can be used as an energy source through a biogas digester. This study aims to determine the production of biogas from waste in a batch digester system. This research uses a digester in the form of a plastic drum with a capacity of 220 liters. 3 treatments were consisting of digester 1 containing cow manure and water (50:50), digester 2 in the form of a mixture of cow manure, chicken manure, and water (30:20:50), digester 3 containing cow manure, organic waste, and water (30:20:50). The digester is then closed tightly for 130 days. The results showed that the daily temperature ranged between 26°−31°C and the acidity (pH) 7-7.62. The biogas production of each digester was then carried out a flame test with a biogas stove. The results of the gas stove flame test show that digester 2 has a longer total flame period of 4302 seconds, then digester 1 has a total flame period of 4034 seconds and lastly, digester 3 has a total flame period of 2370 seconds.
