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.

Abstract The increasing number of people in Indonesia, one of which is the city of Semarang, has led to increased community activities. Increased community activities will affect the increase in the amount of waste production. It will also impact the service life of the landfill, so efforts need to be made to extend the service life of the landfill. Efforts can be made to reduce the amount of waste that goes to the landfill, usually by sorting organic and inorganic waste. Reducing the amount of waste can also be done by utilizing waste that has been buried in the landfill (TPA), then processed into alternative fuels or RDF (Refused Derived Fuel). Waste reduction by sorting organic and inorganic waste has been carried out in several places, namely Putri Cempo TPA, Milangsari, and Sukoharjo, with percentage reductions of 79.6%, 35%, and 58%. Meanwhile, the use of waste into fuel or RDF (Refuse Derived Fuel) can also be used as an effort to extend the service life of the landfill because waste that has been buried for a long time has a high calorific value so that it meets the requirements as fuel for the pyrolysis process.

Capacities of Cipayung landfill (final processing) has exceeded capacity. The composition of organic waste is the most dominant waste composition. This study aims to assess the critical flow of municipal solid waste management system in the Cipayung landfill thus be predicted or estimated improvement of waste management system in the landfill Cipayung. The research method using MFA STAN software for a period of one year beginning in 2017 until 2018. The results of this study are critical flow of waste management systems are in the process of sorting and empowerment are still done manually, so the impact on increasing the amount of garbage residue will be dumped in Cipayung landfill. Waste composition which includes the critical flow is organic waste, plastic, paper, glass and aluminum. All materials that are at a critical flow still can be empowered using mechanical sorting machines garbage. Management recommendation is to apply the technology of recycling, composting and RDF feedstock. The government should establish cooperation with the private sector to process waste into resources that extend the life of landfill serviceability. Through optimization scenario 1, the critical flow of waste management systems can be improved with a reduction of more than 50% of the waste to be dumped into landfill Cipayung.

The mining industry plays a significant role in economic growth and development. Coal is a viable renewable energy source with 185.175 billion deposits in Thar, which has not been deeply explored. Although coal is an energy source and contributes to economic development, it puts pressure on environmental sustainability. The current study investigates Sindh Engro coal mining’s impact on environmental sustainability and human needs and interest. The Folchi and Phillips Environmental Sustainability Mathematics models are employed to measure environmental sustainability. The research findings demonstrated that Sindh Engro coal mining is potentially unsustainable for the environment. The toxic gases (methane, carbon dioxide, sulfur, etc.) are released during operational activities. The four significant environment spheres (atmosphere, hydrosphere, biosphere, and lithosphere) are negatively influenced by Thar coal mining. The second part of the analysis results shows that human needs and interests have a positive and significant relationship except for human health and safety with Sindh Engro coal mining. Environmental pollution can be controlled by utilizing environmentally friendly coal mining operations and technologies. Plantation and ecological normalization can protect the species, flora, and fauna of the Thar Desert. The government of Pakistan and the provincial government of Sind should strictly check the adaptation of environmental standards. Furthermore, the researchers should explore the environmental issues and solutions so that coal mining becomes a cost-efficient and environmental-friendly energy source in Pakistan.

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.

The larvae of the black soldier fly (BSF), Hermetia illucens L., are commonly associated with decaying organic wastes. Over the past 15 years, investigators in China have conducted extensive research exploring the use of BSF larvae to recycle organic materials as a means to protect the environment, while producing products of value, such as protein and bioenergy. Initial efforts were based on a BSF strain from the USA. However, since then, H. illucens strains from specimens collected in Hubei and Guangdong Provinces have been established and used as models to explore the use of this species in sustainable agriculture. China has played an instrumental role in developing an in-door breeding method using a quartz-iodine lamp rather than depend on natural sunlight. This discovery has allowed the establishment of in-door BSF colonies in regions throughout the world where abiotic conditions (i.e. cold temperatures) are preventative. Researchers in China paved the way for using microbes as a means to enhance BSF production including, enhancing BSF egg-laying as well as waste reduction. Furthermore, bacteria from BSF gut or waste can be cultured and used to promote BSF growth, shorten conversion time, and enhanced conversion efficacy. Recent efforts have demonstrated BSF larvae can degrade antibiotics as well as suppress noxious odours in livestock manure. Due to the efforts of research on BSF in China, numerous companies that recycle organic waste at a large scale (>20 tonnes waste digested/day), have been established. Resulting products include insect powder, and live BSFL that can be used as animal feed ingredients for livestock (e.g. eels and frogs), while protecting the environment. Future work will decipher the mechanisms regulating BSF larval conversion of organic waste so that the system can be optimised. However, efforts are still needed at the government level to establish quality assurance standards if this process is truly to become established as an industry in China.

Tires provide a resource of significant interest to many utilities. Tires—and tire-derived fuel (TDF)—have a high calorific value along with other favorable fuel characteristics. At the same time they present material preparation and handling issues for fuel users. For environmental reasons, they are more difficult and costly to dispose of in landfills. In 1990, only 25 million tires or 11% of the annually generated scrap tires in the U.S. were utilized (recycled, retreaded, and burned for energy). In 1994, this number increased to 138 million tires or 55% of the annually generated scrap tires with the largest increase due to tires used for energy (101 million tires). With an estimated number between 1–3 billion tires in stockpiles throughout the United States, this potential energy source is enormous. This paper will review several commercial demonstrations of tire-derived fuel cofired with coal in industrial and utility furnaces. Included will be discussions on fuel characteristics, preparation and handling of the tire-derived fuel, methods of utilization of the cofired fuel including appropriate combustion systems (e.g., cyclone boilers, stokers, fluidized bed boilers) and environmental results of the cofiring demonstrations.
