While the successful reclamation of coal post-mining land sites in Indonesia has been evaluated, no cost-benefit analysis has been carried out on the reclamation of mined land, and the impact of the reclamation work has not been determined. The results of this case study indicate that reclamation work is not an emission-free process, but that the benefits delivered from this work are considerable. It was found that the emissions involved at the coal mined reclamation in Indonesia were 25.4–26.6 t-CO2/ha, with topsoil management and land preparation contributing over 98% of the total emissions (9.5 t-CO2/ha and 16 t-CO2/ha, respectively). The ability of the trees on the reclaimed land to absorb CO2 emissions was calculated to be 26.4 t-CO2/ha, with the amount of oxygen produced calculated to be as much as 143 t-O2/ha of oxygen. The economic value of the ecosystem services delivered by reclamation was over USD 27,750/ha. This is higher than the USD 8642–9417/ha cost of establishing the reclamation work. Improvements to reclamation work could be designed mining and reclamation plans with attention paid to reducing fuel consumption, and therefore, reducing CO2 emissions. Furthermore, law enforcement and transparency, human resource development, and community participation are strongly required.

The importance of recycling end-of-life vehicles (ELVs) has been widely acknowledged as a means of reducing ELV waste to the environment. This reduced environmental waste contributes to achieving a number of UN SDGs, including the creation of sustainable cities. The recovery of secondary resources, such as metals, from the recycling of ELVs also reduces over-dependence on primary resources. This promotes efficient resource utilization and resource conservation. While recycling systems have been established and laws governing ELV recycling have been implemented in some developed countries, there are no such systems in much of the world, and regulations are few if any. To determine the challenges and opportunities for ELV recycling in developing countries, the literature on ELV recycling processes and activities was reviewed, and a SWOT analysis was done based on the data compiled from the literature, to identify the strengths, weaknesses, opportunities, and threats. From the SWOT analysis, the common features identified as opportunities were large market size, low labor cost, and the presence of recyclers of ELV parts. The common strengths were identified to be the vehicle registration system, vehicle manufacturing, ELV legislation, ELV recycling, and the waste management system. In the case of weaknesses, the identified features were the technological capacity, waste regulatory framework, vehicle deregistration, ELV regulatory framework, environmental impact and pollution, and the lack of access to information regarding ELVs, and ELV recycling infrastructure. The common threats were perceived as the little attention given to ELV recycling by the governing authorities, the difficulty of doing business, and political and social instability. The results of the SWOT analysis also showed that the opportunities were considerable and the threats were significant for all of the countries in this study. The weaknesses were significant in Nigeria and the other developing countries, and the strengths of the emerging economies tended to be greater. While weaknesses and threats were clearly identified by the SWOT analysis, the SWOT analysis also revealed the strengths and opportunities for recycling ELVs in developing and emerging countries.
