This study provides insight into the sustainability performance of bioenergy systems for providing cooking and electricity-enabled energy services in the rural growth centres of Zambia. This is achieved by modeling and optimizing a bioenergy supply chain for the provision of these services, and then comparing its sustainability performance to that of existing energy systems. The findings indicate that using biomass-based gasifier-internal combustion engines instead of diesel generators for the provision of electricity-enabled services could result in greenhouse gas, NOX, and SO2 emission reductions of 36, 8, and 97%, respectively. When pellet-gasifier cookstoves are used instead of firewood/three-stone cookstoves for providing cooking services, greenhouse gas and PM2.5 emissions are reduced by 57 and 94%, respectively. Furthermore, households that use bioenergy systems instead of traditional energy systems to deliver cooking and electricity-enabled services can save approximately 275 and 11 US dollars per year, respectively. In general, bioenergy systems outperform existing systems in providing the two energy services in question from a sustainability standpoint. Hence, policymakers must consider their use as alternative energy systems to the existing ones in order to foster sustainable development in rural areas.

Oil palm plantations have been expanded in all regions of Thailand during the past decade to support the higher consumption of palm oil for food and fuel. It is, however, imperative to expand in those areas that have soil quality suitable for oil palm cultivation. Therefore, this study aimed to assess land suitability for the different regions of Thailand where oil palm is being cultivated. The suitability is justified by two aspects, viz., soil quality and remaining suitable areas. The Land Use Indicator Value Calculation in Life Cycle Assessment (LANCA®) method was used for the assessment. The results demonstrated that the soil quality in the southern region was most suitable for oil palm cultivation. Although this region has a lower availability of plantation areas as compared to the other regions, it is still enough to satisfy the forecasted oil palm expansion areas. Meanwhile, although the northeastern region ranked second in terms of appropriate soil quality, it may not be appropriate for oil palm due to the low groundwater regeneration. Hence, it is also important to look at the individual properties contributing to soil quality rather than deciding only on the basis of one aggregated indicator.

In Thailand, many municipalities lack the information to guide decision-making for improving environmental performance. They need tools to systematize the collection and analysis of data, and then to self-assess environmental performance to increase efficiency in environmental management toward a sustainable city. The aim of this study is to develop a platform for self-assessment of an environmental performance index. Nonthaburi municipality, Hat Yai municipality, and Yasothon municipality were selected to study the work context for six indicators, viz., energy, greenhouse gas, water, air, waste, and green area, which were important environmental problems. The development of an online system called “EcoCitOpia” divides municipality assessment into four parts: data collection, database creation, data analysis, and data display. The municipality can use the system for the assessment of environmental performance and the creation of a separate database based on indicators. The system can analyze the results and display them in the form of radar graphs, line graphs, and tables for use in public communication that will lead to cooperation in solving environmental problems at the policy level for urban development to meet the Sustainable Development Goals.

Increasing population and affluence have had a direct influence on increasing the energy demand of nations across the globe. Energy from non-renewable fossil resources has associated emissions of greenhouse gases contributing to climate change, a major challenge facing us today. The governments of many countries have tried to address the twin issues of limited local availability of fossil resources and greenhouse gas emissions by promoting the use of bioenergy. Bioenergy is not automatically sustainable unlike popular belief. Assessing its sustainability using a life cycle thinking approach reveals many caveats, not only regarding greenhouse gas emissions but also other environmental impacts that are often ignored. The environmental assessment of palm oil-based biodiesel shows the trade-offs when considering all the life cycle stages of the biofuel supply chain and also when multiple impact categories are considered. The so-called carbon neutrality becomes questionable and other impacts from agriculture arising due to the use of land and agrochemicals are also seen to be very significant. Ignoring these in policymaking could result in serious unintended consequences. Thus, the importance of life cycle thinking in sustainability assessment is illustrated. This will be critical in addressing national needs while also moving towards the United Nations’ Sustainable Development Goals.

The public transportation system in Bangkok, Thailand relies on environmentally costly diesel buses that contribute daily to Bangkok's air quality problem. Two potential improvements to this highly polluting public transportation system are the implementation of electric or compressed natural gas buses. This paper analyzes the life-cycle environmental impacts using the ReCiPe life cycle impact assessment method (in Global warming, kg CO2-eq, Stratospheric ozone depletion, kg CFC-11-eq, etc.), technical feasibility of implementation, and financial cost of implementing each bus type in Bangkok by calculating these metrics for a single bus and then scaling them to a fleet of that bus type. The entire life cycle of the buses as well as electric bus charging infrastructure is considered. It was found that shifting from diesel to electric or compressed natural gas buses would present a 54–55% or 37–41% decrease in overall damage to human and ecosystem health, an 88% or 80% decrease in resource depletion, and a 48% or 60% decrease in lifetime costs. If the entire diesel bus fleet in Bangkok of 14,127 buses is converted to electric or compressed natural gas buses, the reduction of fine particle (PM2.5) transportation emissions would be approximately 21% and 18%. Of compressed natural gas and electric buses, compressed natural gas buses are the less expensive alternative, while electric buses cause less damage to the ecosystem, human health, and resource depletion. As the environmental impacts of electric buses depend on the regional electricity grid, electric buses also have the potential to further reduce environmental impacts with cleaner electricity production.

The low adoption rates of modern bioenergy systems in the rural areas of Zambia indicate shortcomings within the existing institutional arrangements for a conducive enabling environment for their deployment. To address them, this study employed the SWOT–AHP (Strengths, Weaknesses, Opportunities, Threats-Analytic Hierarchy Process)-TOWS (Threats, Opportunities, Weaknesses, Strengths) technique to assess the effectiveness of such arrangements by building on the insight of the identified stakeholders. This led to the generation of ideas for further policy development for rural-based bioenergy systems. The SWOT-AHP analysis shows that the negative aspects (weaknesses and threats) associated with the enabling environment for the promotion of rural-based bioenergy systems dominate their positive counterparts (strengths and opportunities). Among others, the following policy considerations are vital to the enhancement of the enabling environment in this context: (1) building relevant policy actors' analytical capacity in biomass supply chains for cooking and heating fuels, (2) seeking developed-country support for the effective transfer of bioelectricity technologies, and (3) developing a framework used in planning for the sustainability of rural-based bioenergy systems. To increase the likelihood of their adoption, these strategies must be aligned with the country's higher-level national development goals.

Climate and land use land cover (LULC) changes play a vital role in the hydrology of any river basin. This study was aimed to investigate the impact of climate and LULC changes on streamflow in the Kunhar river basin, Pakistan. The Soil and Water Assessment Tool (SWAT), calibrated on a monthly basis, was used as a hydrological model to study the impact of climate and LULC changes on the streamflow. The change in average annual runoff due to LULC was increased but not significant; on the other hand, the flow was decreased by 24 m3/s (20%) as compared to the baseline (122 m3/s), due to climate change. On the seasonal and monthly scale, a difference emerged between high and low flows; high flows were increasing and low flows were decreasing in the wet and dry seasons, respectively, due to LULC changes. However, due to climate change, the seasonal and monthly runoffs were decreased significantly. Problems such as depletion in surface water and environmental flow during the dry season were more prominent due to the changes in the streamflow. These problems can be mitigated by afforestation in the bare lands and grasslands and taking structural measures to conserve the water in the high flow season for later use.

Promotion of sustainable maize production in Northern Thailand, the country’s largest maize-producing region, is crucial to securing the supply of the nation’s feed manufacturing, as well as protecting environmental resources, enhancing social welfare, and improving the livelihoods of farmers and communities. This study aimed to investigate the various sustainable practices of the smallholder highland maize farmers and determine their environmental perceptions of sustainable practices. Face-to-face interviews with local maize farmers in two northern villages of Thailand showed that the farmers performed more sustainable cultivation practices i.e., avoiding the use of prohibited chemicals, but less post-management practices, i.e., managing residues and disposing of agrochemical waste. In addition, the Chi-square test was employed to determine the correlation between various socio-demographic factors and the farming practices. The surveyed farmers perceived the positive environmental impacts of organic fertilizer application and alternative management methods of residues to slash-and-burn, but they did not perceive the same positive impacts for proper agrochemical waste management on the environment. The results of the constraints to the environmental practices identified by the farmers suggested that additional tangible support from the government, such as agrochemical waste disposal facilities and engagement of policymakers and development practitioners, would result in more local-specific interventions that would promote a sustainable highland agriculture system.

Thailand has developed a national roadmap on sustainable consumption and production (SCP) and implemented green product procurement (GPP), but the effects of GPP on achieving SCP have not yet been evaluated. The strengths, weaknesses, opportunities, and threats associated with policies and practices of 15 key institutions were analyzed to identify gaps and practical issues. The analysis of external opportunities and threats with the internal strengths and weaknesses was performed with the stakeholder consultation of at least 160 participants from governmental and private sectors. GPP has induced an increased number of ecolabelled products and services from more than 1,200 manufacturers; however, it has mainly been focused on office supplies. To move forward, the fiscal budget for purchasing ecolabelled products/services should be continually increased and more building materials and circular products should be added to the list. Manufacturers should be motivated to produce eco products by tax incentives. GPP should be expanded to local administrative organizations and the private sector. The monitoring system must be improved through a digital platform to facilitate online reporting. Life Cycle Assessment should be used for assessing the impacts of GPP, not limited to greenhouse gas reduction. Communication with consumers should be enhanced to understand the value of using ecolabelled products, leading to more participation.

Addressing the increasing burden on land use requires effective policy for sustainable land use along with economic development. Analysis of local and global indicators based on land use maps could reveal information on the progress of sustainable development. This study proposes a method that reduces the time and cost of creating land use maps applicable for many purposes of environmental protection. Freely accessible existing data, Sentinel-2 satellite images, together with a machine learning algorithm, Random Forest, are integrated to generate an annual map, sufficient to meet the intended needs. The method is illustrated by a case study of Phuket in Thailand. An annual map for Phuket created using the proposed method was compared to the official map released by the Thai government for the year 2018. The two maps did not differ significantly, validating the efficacy of the proposed method. Annual maps were then produced for several years to assess the effect of land use change in the past 19 years on the environmental and sustainable management in Phuket. Although there was evidence of the efforts to develop Phuket island as a sustainable province such as the government policy to conserve green areas, land use change based analytical results indicated Phuket's urban development was not going in an environmentally sustainable direction.

Cement manufacturing is an energy-intensive industry which uses a large amount of resources and contributes environmental impacts at both small and large scales. The growth of key world economies has led to an increase in the use of construction materials and therefore in the demand for cement, particularly in the Asian region. With increasing interest on sustainability issues, environmental concerns posed by the cement industry in Myanmar were investigated in order to explore options to mitigate emissions and subsequent environmental impacts. Comparative life cycle assessments were conducted including a base scenario (existing cement production scheme) and five alternative scenarios developed mostly with a focus on energy efficiency and the use of alternative fuels and materials. A cradle-to-gate system boundary was considered, limiting the scope of the study to raw material extraction, transportation and manufacturing. The impact assessment was performed based on the ReCiPe (2016) method. The results showed that the mitigation options employed in specific scenarios led to a significant reduction in major emissions and consequent environmental impacts in comparison with the base scenario. Above all, the ideal scenario (combination of all possible mitigation options) showed the best results enabling a decrease in emissions of CO2 by 10–50%, NOx by 5–23%, SO2 by 4–20% and PM2.5 by 6–22% compared to a base scenario. This resulted in a reduction of major environmental impacts by 10–50% for climate change, 6–27% for photochemical oxidant formation: ecosystem quality, 7–22% for particulate matter formation, 6–22% for terrestrial acidification and 8–64% for fossil resource scarcity.

The development of new bio-based diesel substitutes can improve their compatibility with diesel engines. Nevertheless, for actual implementation, their environmental and economic performance needs to be studied. This study quantified the eco-efficiency of three bio-based diesels, viz., fatty acid methyl ester (FAME), partially hydrogenated FAME (H-FAME), and bio-hydrogenated diesel (BHD), to address the perspective of producers as well as policymakers for implementing the advanced diesel alternatives. The eco-efficiency was assessed as a ratio of life cycle costing as the economic indicator and three different environmental damages—human health, ecosystem quality, and resource availability. The eco-efficiency of FAME was the most favorable among all the potential substitutes with regard to human health and ecosystem quality, but the least favorable for resource availability impact. Even though BHD was beneficial in terms of life cycle costing, it was the least preferable when considering human health and ecosystem quality, though it performed the best for resource availability. H-FAME was also promising, in line with FAME. It is suggested that the technologies for BHD production should be improved, especially the catalyst used, which contributed greatly to environmental impacts and costs.

Improving access to modern energy in rural areas through the electrification of rural growth centres (RGCs) mainly by grid extension remains a challenge in Zambia. During the last 15 years, electrification rates have marginally increased from 3 to 11% for rural areas. This does not only represent the status quo of access to modern energy in these areas but also shows the unlikelihood of attaining the 2030 rural electrification target of 51%. Biomass-based systems offer viable alternatives/complements of supplying modern energy. Sustainable development of these technologies begins with identifying viable bioenergy systems from a wide range of options. Accordingly, this paper focused on a first-level techno-economic assessment of different bioenergy options that employed lignocellulosic residues as feedstock to provide heating/cooking and electricity-enabled energy services in non-electrified RGCs of Zambia. The results indicate that fuels to provide cooking/heating energy services could be supplied by pellets and briquettes in an economically viable manner. Gasification and combustion technologies were more financially attractive compared to diesel generators for electricity production. Therefore, they are viable alternatives for providing electricity, an important enabler for the much-needed rural development in the country. However, at the moment they cannot provide electricity at costs competitive with grid-electricity, partly due to subsidized electricity tariffs in Zambia. It is recommended that a decision support system framework for biomass exploitation using such technologies should be established. Such a framework should guide policy makers to identify optimal means of using biomass to provide modern energy services in the RGCs of the country.

The performance of floating photovoltaics (FPV) was assessed by this study, a technology with rising popularity in the sustainable energy sector, by comparing its economic and environmental benefits to various types of photovoltaic technologies by utilizing Life Cycle Assessment (LCA) and Cost-Benefit Analysis. The largest impacts were shown from this LCA of a 150 MW FPV plant with a 30-year lifespan, which resulted from the roughly 73 kg of greenhouse gases and 110 m3s of water per MWh generated. Additionally, 21 reservoirs were considered in Thailand to house new FPV plants. Projected power generation scenarios varied between 0.64 GW and 13.28 GW when reservoir coverage percentages ranging from 1% to 20% were used. The Levelized Cost of Energy for several different photovoltaic systems yielded 0.24 USD per kWh for the FPV system, while the ground based polycrystalline and thin film systems were 0.43 USD and 0.54 USD per kWh, respectively. The payback period for FPV was 7.5 years, while for the polycrystalline and thin film it was 7.8 and 16.3 years. This combined with other factors made for a high return on investment for the FPV system. This study recommends a 10% coverage of 21 reservoirs throughout Thailand, allowing for potentially 6.52 GW of installed capacity, which would substantially help the country to reach their 2036 goal of having 30% of the energy mix from renewable sources.

In the millions of years of evolution, nature has developed very efficient systems that move all elements and substances in cycles so that there is no waste. Humans, on the other hand, have recently developed industrial systems in the last few centuries that have a linear flow, extracting resources from nature and discarding them as waste after a brief period of use. Solutions to handle pollution have moved from end-of-pipe treatment to cleaner production and now towards a circular economy. A circular economy tries to move away from this linear model in trying to extend the life of products and services while minimizing burdens to the environment. To ensure that there are actually environmental benefits, a life cycle thinking approach is essential. This philosophy is developed in the chapter and life cycle assessment is introduced as an essential tool for environmental evaluation. Case studies on sugarcane biorefinery and packaging materials are provided to illustrate the utility of life cycle assessment in ensuring environmental benefits when approaching circularity.

Bagasse-based electricity is gaining attention as an affordable, reliable, sustainable, and promising renewable energy source in Pakistan. Therefore, the focus of this analysis was to identify the environmental burdens associated with bagasse-based electricity production via high-pressure cogeneration. The scope of this study was defined as cradle to gate; involving cane production, cane transportation to the mill, the production of bagasse, and then the burning of bagasse in the cogeneration power plant to produce electricity. The overall results revealed that most of the impacts were contributed by the agricultural phase. For some impact categories—such as global warming, fine particulate matter formation, terrestrial acidification, and fossil resource scarcity—the bagasse-based electricity performed better than the grid mix electricity. However, the grid mix electricity performed better than the bagasse-based electricity in terms of eutrophication, land use, and water consumption. When considering the final damage, the bagasse-based electricity proved to be the favorable option in terms of human health and resource availability; however, ecosystem quality was poor in bagasse-based electricity. In terms of environmental prices, the bagasse-based electricity was found to be a promising option compared to the grid mix electricity.

Bioethanol is promoted as a transportation fuel due to its perceived benefits; reducing greenhouse gas (GHG) emissions, substituting fossil fuels, enhancing energy security, and promoting the rural economy. This study aims to evaluate the availability potential, energy performance, and environmental sustainability of bioethanol from sugarcane molasses in Pakistan. It was found that the current potential of molasses-based bioethanol is enough to replace around 7% of total gasoline consumption in the country. The results indicated that the use of E10 (10% blend of bioethanol with gasoline) instead of gasoline would result in the reduction of GHG emissions by 8%, human carcinogenic toxicity by 3%, and fossil resource scarcity impacts by 9%. However, E10 has comparatively higher impacts than gasoline on acidification by 20% and on freshwater eutrophication by 43%. Further benefits of molasses-based bioethanol were evident in terms of high energy gains where each MJ of the total energy input provided about 2 MJ of energy output from bioethanol and each MJ of fossil-based energy input resulted in the production of around 6 MJ of energy output from bioethanol. Furthermore, considerable improvements in performance were indicated by contemplating different existing practices and plant arrangements.

This paper evaluated the carbon footprint of the papaya supply chain to Yasothon Market in Yasothon province, Thailand. There is high consumption of papaya in Yasothon municipality but a lack of papaya plantations in the area lead to a vast amount import of papaya. The study developed a green supply chain and logistics model, using network analysis. The best route for each significant case was the shortest route of the total distance from each registered stop. The results of the analysis revealed that papaya distributed from Ubon Ratchathani and Sisaket Farms should use the route generated by driving and distance impedance with the lowest greenhouse gas emissions at 898.42 kg CO2 eq./FU. Meanwhile, the distribution from Nakorn Ratchasima should use the driving distance impedance to generate the route with the lowest greenhouse gas emissions at 987.37 k kg CO2 eq./FU. While the papaya supply chain from Kamphaeng Phet, Kanchanaburi, Lopburi, and Ratchaburi to Khon Kaen Market with driving distance impedance is the best solution among all the alternative routes as it generates the lowest greenhouse gas emissions at 6620.23 kg CO2 eq./FU. The results suggest that the distribution center can help reducing the distance, resulting in reducing greenhouse gas emissions. The results of the study can suggest the sustainable index of the papaya supply chain by comparing the conventional and improved environmental impact of the papaya supply chain from the green logistics model. The alternatives will be the suggestion of pathways towards improvements in green supply chain and logistics of papaya, which can also be considered for implementation in other agricultural products.

Thailand has been implementing its Alternative Energy Development Plan aiming to replace 20–25% of fossil fuels with locally produced biofuels by 2036. The partial substitution of fossil diesel with fatty acid methyl ester (FAME) derived from palm oil is one of the major options but blending beyond 20% of FAME is a concern for use in conventional diesel engines. This problem has led to the consideration of other bio-based diesels also derived from palm oil; namely, partially hydrogenated fatty acid methyl ester (H-FAME) and bio-hydrogenated diesel (BHD). This study performed a comparative life cycle assessment of various bio-based diesels using the ReCiPe life cycle impact assessment method. The results showed that in comparison to fossil diesel, bio-based diesels have superior performance for global warming and fossil resource scarcity, but an inferior performance for eutrophication, terrestrial acidification, human toxicity, and land use. Considering the collective environmental damages, BHD performed the worst for human health, and all the bio-based diesels showed poor performance for ecosystem quality, while diesel showed poor performance for resource availability. Among the bio-based diesel products, BHD has higher environmental burdens than FAME and H-FAME. Improvements have been suggested to enhance the environmental performance of the bio-based diesels.

The current model of a linear economy with end-of-pipe waste treatment is not sustainable. Cleaner production helps reduce resource use and emissions, but is still not an optimal solution without considering a life cycle perspective. Life cycle-based tools such as life cycle assessment and life cycle costing are useful for identifying optimal environmental and economic options for product systems. SDG 12 dealing with responsible consumption and production is key for sustainability. Developing of a circular economy requires life cycle thinking and life cycle-based tools for assessment. All these issues are discussed along with illustrative examples.
