“…Table 2 summarizes CO 2 reduction, leachate avoidance, and landfilling area minimization. The factor X C (taken as 694.0 kg CO 2 per MWh) is used as the base for CO 2 emissions when generating 1 MWh of energy in the form of electricity [38]. It represents the total greenhouse gas released into the atmosphere by fossil fuel-based power plants, which can be offset by generating electricity and distributing it via sustainable energy sources such as solar, biomass, and biogas.…”

Estimation of Sustainable Bioenergy Production from Olive Mill Solid Waste

The disposal of olive wastes and their wastewater is a major problem worldwide. An important recycling chain can be formed through biogas production and energy conversion from olive waste. This study developed an efficient and effective sustainable model for biogas production using anaerobic digestion conditions with the co-digestion of pretreated olive waste. The sample used was hard olive pomace, which was dried in an oven before being crushed to fine particles with a mortar and pestle. The sample was analyzed by a CE-440 Elemental Analyzer, and Fourier Transform Infrared Spectrophotometer (FTIR) analysis was performed using Shimadzu IRTracer-100. Through the analysis, a substantial amount of electrical energy of 769 kWh/t was found to be generated per ton of olive pomace due to the high volatile solid (VS) percentage of organic waste material incorporated during the calculation. Reduced land area for landfilling olive waste was calculated to be 108 m2 per year, whereas the potential to reduce landfill leachate production was evaluated to be 0.32 m3 per year.

“…However, this resource is yet to be used, and the reasons beyond this phenomenon are different and could be summarized as follows: first, lower awareness of these resources; second, as the biomass comes from an unclean material, people are hesitant to use it even though it could be used by small farms and could reduce fuel and electricity used. Bioenergy could reduce the dependency on the conventional energy imported and fuel prices, especially for the rural area, create new jobs, and boost the concept of green energy security 58,59 …”

Palestine has considerable potential for bioenergy production, which can contribute to the independence of the nation's energy sector. However, few projects have been implemented for the production and utilization of bioenergy. In this study, the potential effects of using bioenergy from various sources, such as municipal solid waste, wastewater treatment plants, and animal farms are studied. Certain studies and successful projects in Palestine are evaluated. Different technologies that could be used effectively are introduced. The challenges facing the adoption of bioenergy are discussed. The effect of energy generation is studied, and an economic analysis is performed. Results show that if bioenergy is adopted in the cities of Palestine, then approximately 19% of the total energy demand can be covered. Based on successful, established projects, Palestine has promising potential to generate low‐cost energy from bioresources. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd

“…Malaysia is a developing country that experiences rapid urbanization and population growth. Consequently, the generation of municipal solid waste (MSW) is increasing as it has a proportional relationship with the population growth rate, and it is predicted to reach 49670 tons per day by 2030 [1]. MSW encompasses the waste produced from residential, commercial, institutions and parks [2].…”

“…Malaysian government has also decided to adopt these sustainable promising solutions and discard the previous practice which used mostly unsanitary landfill and open dumpsite that result in severe environmental issue. WtE technologies implemented in Malaysia at present is landfilling with gas recovery and incineration [1]. The objective of this paper was to discuss the application of energy recovery from municipal solid waste in Malaysia.…”

The elevation of waste generation subsequent to population growth has become a severe environmental topic in Malaysia. Since most of the waste is being dumped into a landfill, the open dumpsite, or unsanitary landfills which are not constructed with proper engineering plan, severe impacts on the environment result. The energy demand in Malaysia increased with the growing population, but reliance on fossil fuels to generate electricity has created another greenhouse gas contributor. Alternatively, waste-to-energy technology solves the problem of increasing waste by converting the waste to a renewable energy source. Malaysia has moved towards landfill gas recovery system and incineration for waste energy recovery. The recovery system and refuse-derived fuel plant achieved expectation; however, the incineration plants have failed due to the opposition of the public, lack of funding and technician expertise, and other technical issues. The solid waste management practices lacking separation and recycling sources, become an obstacle for development. The government puts effort into solving the current issue by promoting recycling in the public, enforcing the legislation, and approaching new technologies for better solid waste management practice in the future. This paper aims to discuss the application of energy recovery from municipal solid waste in Malaysia.
