As the automotive industry shifts from internal combustion engine (ICE) vehicles to electric vehicles (EVs), many countries are setting new strategies in their transportation sector. The Li-ion battery is currently the most common battery used in EVs due to its high energy density, durability, safety, and cost competitiveness. Nickel is predicted to be an essential component for the lithium nickel cobalt manganese oxide (NMC) as a cathode material of choice for EV applications. Indonesia, one of
As a net oil importer since 2004, Indonesia’s success in developing fuel economy and infrastructure for electric vehicles would be vital to ensuring energy security and decarbonization from the transport sector. Following the Presidential Regulation on the Acceleration Program for battery-based EV for Road Transportation in 2019, the Indonesian government provides incentives for the domestic production of EVs. However, as EV technology is relatively new for the domestic automotive industry in In
There is a widespread interest in converting organic waste into compost fertilizer to extend the life of landfills, create economic and environmental benefits, and ultimately reduce the pressure on local governments in managing the ever-increasing complexity of municipal solid waste. However, composting is still seldom considered as a strategic element. There is also very little evidence available of its economic feasibility. This study, therefore, aims to analyze key factors that influence the
Due to its ability to recover both material and energy from organic waste, biogas technology is considered one of the best technology for treating organic waste. While in many emerging Asian countries more than 50% of municipal waste is organic waste, the amount of organic waste treated with biogas technology remains very limited. This study identified key challenges faced by practitioners in sustaining biogas plants from literature and interviewed a number of sustainably operating biogas plant
Access to clean energy for communities living in remote areas where grid extension is considered unfeasible can be provided by off-grid electrification systems using renewable energy (RE). Especially in developing countries, ensuring the appropriateness of such systems is crucial because it will determine the system's sustainability despite its limited resources. This study demonstrates the design process of an appropriate system by assessing the potential of three RE sources: solar, wind, and b
In Japan, mechanical plastic recycling has been widely practiced. In recent years, the chemical recycling method has been gaining interest, especially due to its high-quality products similar to virgin materials. Understanding the environmental impact of both methods from the energy consumption standpoint is crucial so that attempts to preserve plastic resources can be based in the most energy-sustainable way. This research aims to determine the environmental impact of mechanical recycling and t
Under the Sustainable Development Goals (SDGs), the world has pledged to “leaving no one behind”. Responding to goal No. 7 on the agenda, efforts to provide modern energy to all the world population must be pushed forward. This is important because electrification in the rural area can indirectly support opportunities for social and economic development resulting in an acceleration of the eradication of poverty. The research goal of this study is to contribute insights about the scale of energy
With Japan facing workforce shortages and the need for enhanced recycling systems due to an aging population and increasing environmental challenges, automation in recycling facilities has become a key component for advancing sustainability goals. This study presents the development of an automated sorting robot to replace manual processes in beverage container recycling, aiming to address environmental, social, and economic sustainability by optimizing resource efficiency and reducing labor dem
Abstract The COVID‐19 pandemic has increased the need for social distancing and improved sanitation to prevent the spread of infectious diseases. In the waste management sector, protecting the safety and health of waste collection labourer has become a priority. In Japan, the labour shortage problem and ageing demography have intensified the need for contactless waste collection technology. This study responds to this need by reviewing the global practice of smart waste collection technologies a
Mobility is essential for maintaining human well-being, as it aids in accessing basic needs and engaging in social activities. For older adults who drive, driving provides a sense of independence and convenience, allowing them to go wherever and whenever necessary. However, the declining physical condition and cognitive functions of older adults may eventually hinder their ability to drive safely. In Japan, many older drivers prefer to continue driving unless they are officially deemed unfit, re
The mobility sector is experiencing a global transition towards cleaner and more sustainable technologies. Many mobility projects are developing artificial intelligence (AI) technologies to improve the operational efficiency of mobility, such as charging system optimization for electric vehicles (EVs), autonomous driving, and traffic controls. This study presents such projects’ global distribution by showing a geographic information system (GIS)-generated map and analyzes the readiness level of
Smart bins can increase transparency and accuracy in monitoring waste characteristics such as weight, volume, and disposal times. This information can aid in enforcing waste reduction policies, including the pay-as-you-throw (PAYT) system. However, the public's response to this technology remains uncertain. Despite Japan's reputation for high waste separation compliance and collection rates, it has one of the world's highest per capita rates of plastic and packaging waste generation. This study
Biomass is a promising energy resource for the Southeast Asian countries. There are currently many biomass related technology development projects taking place in the emerging countries of the region (Thailand, Indonesia, Viet Nam, Myanmar, Philippines, Malaysia, Cambodia, Laos). In this paper, we investigate the critical characteristics of Japan-supported biomass energy technology development projects in those countries, specifically on; technology type, biomass feedstock type, the technology's
Pursuing Sustainable Development Goal (SDG) number 7, to “Ensure access to affordable, reliable, sustainable and modern energy for all,” many off-grid villages received solar panels from external supports. However, these communities rarely have the capacity for reinvestment when the battery deteriorates. This study proposes reusing the abandoned solar panels as a power supply for cellphone charging stations and signal boosters. Taking an off-grid agricultural village in Indonesia as a case study
