“…An exception is bread separation in some schools; this probably happened, as mentioned before, due to religious/cultural reasons in Jordanian culture. The results also show that glass and plastic form the highest constituent of the SW generated in all schools [Berber et al, 2017;Hamoda and Abu Qudais, 1998].…”

This study evaluated the process of in-site sorting of the generated solid waste (SW) in some educational institutions in Ma'an city, Jordan. The study included eight schools and one University. The students and employees of seven schools, as well as the students and employees of the University, had received the awareness campaigns concerning the importance and benefits of in-site sorting of SW. As a control, one school student and employee who had not received awareness campaigns were involved. The institutions were provided with four bins at each collection site (glass and plastic, paper and cardboard, metals, and bread). The content of bins in each institution was collected and sorted manually to evaluate the efficiency of the conducted awareness campaigns on onsite sorting behavior. The mass ratios of many SW components in their designated bins in the reference school (control) were higher than the average ratios in the assigned bins for the same component in all schools. As for the University, the results of the manual sorting showed that all bins included a mix of SW in different ratios; moreover, the proportions of glass and plastic, and metals were lower than the proportions of other components. On the basis of the above mentioned results, it can be concluded that the awareness campaigns did not achieve the stated goals; subsequently, the in-site sorting failed in the schools and the University. Thus, different awareness campaigns should be assessed to identify the best approach positively affect the SW sorting and disposal habits of people.

“…Indonesia with its WtE scenario of 1000 tons of waste/day, tipping fee of IDR 600,000/tons, or an electricity price of IDR 1,750, generates a Net Present Value (NPV) of IDR 209.7 billion or 133,500 EUR [21]. Another feasibility study shows that if WtE in Estonia applies carbon mineralization with a waste-to-product (construction materials) or waste-to-safe-landfill approach, the resulting NPV is 9,209,662 EUR or 387,931 EUR, respectively [22]. This additional profit could be an opportunity in overcoming the financial problems of WtE in Indonesia if integrated with CCUS -carbon mineralization technology.…”

Several issues such as environment, finance, and policies in the development of Waste to Energy (WtE) in Indonesia require strategic and appropriate handling. This study offers a promising solution by integrating WtE incineration process with carbon mineralization as one of Carbon Capture, Utilization, and Storage (CCUS): adding CO2 capture technology to the existing system and CO2 will be reacted with fly ash residue producing insoluble carbonates to stabilize the heavy metals contained. Moreover, with a combustion capacity of 1000 tons of waste/day scenario, it is equivalent to a reduction of carbon emissions of up to 25 tCO2 per day. A feasibility study in Estonia revealed that if WtE is integrated with carbon mineralization, the resulting Net Present Value (NPV) is up to 9,209,662 EUR. This can be an opportunity for Indonesia to solve the financial issues as the existing WtE only generates 133,500 EUR of NPV. Additionally, the existing policy states that the construction of a WtE plant must be accompanied by a residue treatment plant facility. So that in addition to increasing profits and environmental benefits, this integration also can help simplify the complexity of WtE development requirements because residue treatment becomes easier.

Feasibility and Barriers for Anaerobic Digestion in Mexico City

Due to the high organic fraction in municipal solid waste (MSW) composition in Mexico City, anaerobic digestion (AD) is considered as a viable treatment method for organics in this study. The most feasible way refers to the waste from the wholesale market Central de Abasto, which is predominantly organics. This work aims to perform a business plan and discuss the barriers for AD technology in Mexico. In this case study, the cost-benefit analysis (CBA) approach is applied to estimate the profitability of the project. The net present value of this project is positive, and the model resulted in a payback period of 7 years. Identified barriers to feasibility of energy generation through biogas of MSW in Mexico include the need for large investment, low profitability through sales of electricity, and no use for generated heat. An attractive panorama for clean energy in Mexico was not evidenced, even though the Energy Reform took place in 2013. However, the environmental analysis also demonstrates a positive environmental impact of 730 kg CO 2 per 1 Mg of MSW. Therefore, support incentives are needed to promote the use of other by-products of the AD process, such as heat and digestate.
