This study assessed the environmental performance and energy efficiency of electricity generation from rice straw using a combined gasification and internal combustion engine (G/ICE). A life cycle assessment (LCA) was performed to consider the conversion to electricity of rice straw, the production of which was based on the Philippine farming practice. Rice straw is treated as a milled rice coproduct and assumes an environmental burden which is allocated by mass. The results of an impact assessment for climate change was used directly in a system dynamic model to plot the accumulated greenhouse gas emissions from the system and compare with various cases in order to perform sensitivity analyses. At a productivity of 334 kWh/t, the global warming potential (GWP) of the system is equal to 0.642 kg CO2-eq/MJ, which is 27% lower than the GWP of rice straw on-site burning. Mitigating biogenic methane emissions from flooded rice fields could reduce the GWP of the system by 34%, while zero net carbon emissions can be achieved at 2.78 kg CO2/kg of milled rice carbon sequestration. Other sources of greenhouse gas (GHG) emissions are the use of fossil fuels and production of chemicals for agricultural use. The use of agricultural machinery and transport lorries has the highest impact on eutrophication potential and human toxicity, while the application of pesticides and fertilizers has the highest impact on ecotoxicity. The biomass energy ratio (BER) and net energy ratio (NER) of the system is 0.065 and 1.64, respectively. The BER and NER can be improved at a higher engine efficiency from 22% to 50%. The use of electricity produced by the G/ICE system to supply farm and plant operations could reduce the environmental impact and efficiency of the process.

Sustainability in the fashion industry is a contemporary megatrend that needs new studies addressing the myriad of possibilities that exist to reduce environmental impacts. Nonetheless, it is essential to take into account the opinions/wishes of the segments targeted by the business, a practice that has been neglected by textile and fashion companies. Value offers with greater circularity in textile and fashion businesses have suffered from a lack of consideration of the consumer’s perspective in their value propositions. Therefore, the objective of this research is to suggest circular strategies for the incorporation of the consumer’s perspective into value creation in the fashion industry. The methods used in this chapter encompass four steps: (i) building a theoretical background related to sustainable and circular fashion, and circular business models linked to the textile and fashion industry, which aided; (ii) building a survey to investigate issues on product design, value creation, and consumer participation in fashion companies in Brazil; (iii) identifying the main deficiencies on product design, value creation, and consumer participation in fashion businesses in Brazil; and (iv) proposing circular strategies to seek overcome the deficiencies identified. Twenty companies from three states in Brazil were surveyed. The results of the survey allowed identifying gaps in the knowledge of fashion companies in relation to consumers and also with regard to issues that involve the product’s life cycle from the conception, use, and disposal of post-use products by the consumer. Recommendations were proposed to incorporate the consumer’s perspective into creating value in the fashion industry, seeking to pave the way to more circularity-oriented business models in the textile/fashion industry.

This systematic review examines the importance of a systems/holistic approach in analyzing and addressing the footprints/impacts of business-as-usual activities regarding the development of a circular economy (CE). Recent works on why current CE approaches have to be examined in terms of reductionist vs. systems perspectives are reviewed to tackle questions pertaining to the right or the wrong way of CE implementation. ‘Doing the right thing right’ is essential for sustainability—the ultimate goal of a CE, which must be viewed as a system to begin with. The limited reductionist approach overlooks and thus cannot prognosticate on the formidable unintended consequences that emerge from ‘doing the right things wrong’, consequences that become too costly to undo. The systems approach, being holistic, is complicated and difficult to pursue but open to exciting opportunities to integrate innovations in CE analysis and implementation. Complexity is an inherent downside of the systems approach. However, both approaches are complementary, as reductionist models can be combined to create a system of comprehensive analysis to correct the approach towards implementation of current CE initiatives. This review reports that advancements in systems analytical frameworks and tools are highly important for creating general guidelines on CE analysis and implementation.

The aim of this article is to identify both the circular economy strategies with the most influence for managing each business model building block in circular businesses; and the business model building blocks that are most affected by circular economy strategies. A systematic literature review was conducted to identify potential circular economy strategies, resulting in sixteen such strategies. Thereafter, a survey was conducted with experts to indicate how important the strategies were for managing each building block (business model Canvas) using a Fuzzy Logic approach. The survey, using fuzzy linguistic variables, was sent to specialists in circular business models worldwide. The circular economy strategies that influence business modelling to a greater extent are developing strategic partnerships for circularity and engaging stakeholders along the value chain, and digital technologies (e.g. Industry 4.0) to enable circularity. The building blocks most influenced by circular economy strategies are customer segments, customer relationships, and key partnerships. The analysis made in this research indicates where companies should focus their efforts towards managing their businesses when implementing/managing different CE strategies.

Australia has intensified its circular economy (CE) efforts that demonstrate designing out waste while creating wealth. It has developed eco-industrial parks in metallurgy/metal industries, eco-cities and small-scale waste-to-wealth creation strategies. Mining has taken the lead in CE development with the eco-industrial areas at Kwinana, Western Australia, and Gladstone, Queensland. Easing up the waste burden, eco-efficiency and value addition are the direct benefits of circularizing the economy. Shortsightedness in looking up for opportunities across the supply chain, technological constraints, lack of policy coordination for business innovation, economic recession induced by the COVID-19 pandemic and lack of incentives to change behavior from linear to circular economy are among the barriers pointed out. A systematic review of published literature in Australian context was conducted to assess the state-of-the art circular economy development. We have found that Australia has to look into overcoming the barriers by putting in place policies and guidelines to nurture the current synergies, business relationships and trust among the firms in partnership, and more R & D to meet the demand for complementing technologies and to have cohesion over the current CE strategies, among others.

Global industrialization has accounted for large amounts of generated waste, which have accumulated over the years. To guarantee that the future generations will have sufficient resources like food, water and prosperity, it is therefore necessary to transition from a linear economy to a circular economy. Circular economy is one concept, which has continued to gain traction over the years as an effective approach to achieve global, national and local sustainability. A systematic review was employed in this research project with the purpose of identifying how the practical contributions of circular economy have been pursued actively in Australia and other developed countries by reviewing existing and relevant published studies on circular economy in these countries. The result produced a total of 70 final articles, which were collected and analysed for the study considering mainly the year of publication, research methodology, geographical context and industrial applications. Furthermore, the study highlighted very little attention is given to circular economy in many low-income and medium-income countries, and thus, this study explored how this transformative notion can be adopted in developing countries with the participation of key stakeholders to solve waste mismanagement problems.

Current global pressures on natural resources requires incorporating the environment into national planning and budgeting processes if sustainable development is to be realized. Thus, the role of National development planning in setting up objectives for all levels of government, directing national budgetary processes and managing support from external sources makes it an important driver in any country's environmental management system. Agenda 23 of the United Nations general assembly tasked each country with developing responses that would meet the overall implementation of the agenda, by building on existing appropriate planning instruments with the aim of supporting a transition to the Sustainable Development Goals. Zambia's current Seventh National Development Plan makes mention of the country's potential to productively harness its renewable and natural resources, and lists examples of what can be done. However, it does not explain how this will be done and what measures will be taken to achieve these sustainable goals. The aim of this paper was to review and evaluate gaps in how environmental management policies are incorporated into national development plans and, based on the findings, revise national policies in the goal of achieving sustainable development. A systematic quantitative literature review was carried out, and 19 pieces of literature met the criteria for evaluation. The findings revealed that incorporating environmental management policies into national development planning processes is multi-faceted and should be treated as long term programme. It also showed that keeping the focus on specific issues, places and people makes a stronger case for mainstreaming. They also showed that concentrating on key mainstream institutions and processes is more productive when considering policy processes. The findings though did not indicate whether facilitating projects at local government levels makes mainstreaming programmes more successful. It also did not indicate whether data acquired through monitoring can help determine if a national plan is more effective than a local level or micro-project plan when carrying out environmental mainstreaming. These are options for further research.

Agricultural crop residues are available in abundance in Asian countries such as the Philippines. These residues have high potential as feedstock to produce clean and high-value energy products, to mitigate global warming and reduce dependence on fossil fuels. This study investigated the carbon footprint and energy performance of biohydrogen production system through gasification of different waste agricultural biomass. The proposed system includes biomass transport and pre-processing, gasification process, and biohydrogen enrichment and purification technologies. Calculation of the syngas composition was performed using a stoichiometric-thermodynamic equilibrium model using python script. Generation of energy from fossil fuel to support the system operations produced the highest greenhouse gas emission. The production system using sugarcane leaves as feedstocks exhibited the lowest carbon footprint, highest gasification efficiency, and best energy performance based on the computed energy ratio. Biophysical allocation was used to determine the burden associated with the biomass during its growth phase. Incorporation of the carbon uptake during biomass growth phase reduced the carbon footprint of the system. Sensitivity analysis showed that increasing C/O and H/O ratio improves the quality of the syngas produced, while increasing C/H ratio results to lower biohydrogen yield. In selection of feedstock mix, it is preferred to maximize C/O and H/O ratio while reducing C/H ratio of the feedstock composition.

The circular bioeconomy represents an opportunity of nearly USD $8 trillion until 2030. However, innovative business models are needed for a circular bioeconomy to succeed. What mostly lacks in the body of research on business models for the circular bioeconomy, and what marks the originality of the present article, is summarizing the key aspects that need to be considered when designing, implementing and managing businesses in a circular bioeconomy. Therefore, this study’s aim is twofold (i) to reveal key aspects for implementing and managing business models for a circular bioeconomy; and (ii) to point out the issues that lack further research on the theme, based on the existing literature. A systematic literature review was conducted on the Science Direct, Scopus and Web of Science databases. Key aspects for implementing and managing business models were identified according to the business model Canvas framework. Key aspects are related to the role of innovation and new markets, taking the customer perspective into account in the value creation process and being close to customers, adequate management of logistics and feedstock collection systems, being aware of different routes for valuing biomass, seeking technological development, building resilient value chains, and focusing on value creation to cover costs. Issues that need addressing in the existing literature include product-service-systems, take back-systems, seasonal availability of resources, social impacts, rebound effects, and aquatic activities.

Renewable energy has been prioritised in decarbonising Indonesia’s electricity system. Indonesia aims to attain an efficient energy system by applying renewable energy tariffs that are lower than the cost of fossil fuel-generated electricity. However, the effectiveness of this policy is questionable, as renewable energy investments under previous premium feed-in tariffs did not meet expectations. This study aims to estimate generation costs from renewable energy expansions under three scenarios, namely existing power plant planning, and 11% and 14% emission reductions in Indonesia’s electricity sector. We develop an agent-based model (ABM) tool called PowerGen-ABM that employs multi-approaches: linear programming and input-output analysis. The optimisation result shows that the emission reduction targets would increase the average electricity generation costs in 2028 from 65.3 USD/ MWh in the existing plan of power plant expansions to 68.3 USD/ MWh. The increased costs are caused by insufficient dispatchable renewables in several regions such as North Maluku. Renewable energy production share in total electricity production and emission reduction achievement of the existing plan in 2025 will be 22.8% and 6.5% below the targets of 23% and 11%, respectively. In contrast, the emission reduction scenarios could achieve those targets due to higher renewables productions, especially with wind energy from 5,268 GWh in the existing plan into anywhere between 64,472 to 75,085 GWh. Several policy implications are discussed based on these findings.

Solutions that effectively promote sustainable development in urban environments require an understanding of the complexity of human-environment interactions. This paper adopted a systems-based framework to understanding how social, organisational, and environmental factors interact within an urban system in China. Drawing upon a case study from the industrial city of Jinchang, it applied a qualitative bottom-up approach to understand these key factors operating from three perspectives: the commitment of stakeholders, institutional development and personal development of social systems. It revealed that decision-making mechanisms play a key role in improving the sustainability of governance, and that public-private cooperation and public participation are critical for innovative knowledge-based strategies. The key for improving institutional development is to reform the evaluation system of governance thus enhancing the capacities of decision and policy makers, and consequently improve the process of decision-making. Cultural and personal development are important soft power components that influence individual pro-environmental behaviour and performance toward sustainability. The results demonstrated how, in a Chinese context, the urban social system can be understood and urban sustainability can be promoted through environmental adaptation supported by joint efforts from governments, businesses, society and individuals. In this, China does not differ from other nations in spite of significant differences in cultural and political systems. This study contributed to a better understanding of complex urban systems, providing a bottom-up approach and knowledge for enhancing the adaptive capacity toward urban sustainability.

Failures of countries to set and achieve renewable energy targets are prevalent, producing uncertainty as to the possibility of renewable energy contributing to a reduction in global emissions. Lack of policy and incorrect modelling analyses are among the sources of these failures and understanding these two sources is crucial for improving confidence in renewables. We assess errors in projections pertaining to the capacity and production of renewable energy in the United States and those countries of the European Union that have strong commitments to green energy supply. Our results show that solar energy has the lowest level of uncertainty as it has the most achievable capacity projections. However, other renewables entail more attractive policies and further research is needed for the advancement of reliable technology and accurate weather predictions. Our findings also provide ranges for the projection uncertainties for six renewable energy technologies, drawing attentions to ways that the dominant errors in these renewable energy projections may be rectified.

This study develops a hybrid energy agent-based model that integrates the input–output analysis, environmental factors and socioeconomic characteristics of rural and urban households in Indonesia. We use the model to estimate the effects of four solar energy policy interventions on photovoltaic (PV) investments, government expenditure, economic outputs, CO2e emissions and the uses of steel, aluminium, concrete and energy. The results of our analysis call for the abolition of the PV donor gift policy, the improvement of production efficiency in the PV industry and the establishment of after-sales services and rural financing institutions. A 100 W peak (Wp) PV under this recommendation would be affordable for 80.6% of rural households that are projected to be without access to electricity in 2029. Net metering is the most effective policy for encouraging urban people to invest in PV in a situation where fossil energy prices are increasing and PV prices are declining. A donor gift policy may induce USD 51.9 new economic outputs for every Wp of PV operating to capacity in 2029, but would require a subsidy of USD 18.6/Wp. The recommended policies do not require subsidies and reduce CO2eq emissions and the consumption of aluminium, energy, steel and concrete by between 83.1% and 89.7% more than the existing policy. Several policy implications are discussed in response to these findings. As a contribution to energy modelling literature, the model can be used for other developing countries by merely changing its data.

This study estimates the influence of income, electricity price, oil price, urbanization, and Asian economic crisis to electricity demands in residential, industrial, and commercial sectors of Indonesia using autoregressive distributed lag (ARDL) method. Our estimations reveal that electricity demands in all sectors during the period of 1969–2015 are significantly affected by income and urbanization in which the demands in all sectors are elastic to urbanization but inelastic to income. On the other hand, electricity price only significantly affects residential electricity demand while oil price does not have significant influence on electricity demands in all sectors. The electricity demands in residential and commercial sectors are also significantly inelastic to the number of electricity customers while Asian economic crisis in 1998 only affects industrial electricity demand. These findings are like most previous studies for other country cases but not to previous Indonesian studies that had suffered from the cointegration issues.

Renewable energy (RE) and energy efficiency (EE) are globally promoted as measures to reduce greenhouse gas (GHG) emission and response to climate change. Under the context of budgetary constraint, especially in a developing country like Vietnam, different energy-related solutions should be weighted to obtain the appropriate solutions at a reasonable cost. In this paper, which is a case study in five Mekong provinces, the marginal abatement cost curve has been utilized to analyze the contribution of RE and EE solutions to GHG emission as well as their abatement costs, by 2020. The results indicate that all RE and EE solutions bring a total emission reduction benefit of 11.47 million tCO2e by 2020, being equivalent to 26.5% of the total emission of the five provinces. The abatement costs ranged from −US$59.71 to +US$318.53 /tCO2e.

Renewable energy planners in developing countries should be cautious in using analytical tools formulated in developed countries. Traditional energy consumption, economic and demography transitions, high-income inequality, and informal economy are some characteristics of developing countries that may contradict the assumptions of mainstream, widely used analytical tools. In this study, we synthesize the debate in previous review studies on energy models for developing countries and then extend the scope of the previous studies by highlighting emerging methods of system thinking, life cycle thinking, and decision support analysis. We then discuss how these tools have been used for renewable energy analysis in developing countries and found out that not all studies are aware of the emerging critical issues in developing countries. We offer here a guidance to select the most appropriate analytical tool, mainly when dealing with energy modeling and analysis for developing countries. We also suggest potential future improvements to the analytical tool for renewable energy modeling and analysis in the developing countries.

Purpose The intervention of many different organizations during the post-disaster housing reconstructions could also influence the sustainability of the overall socio-ecology of the affected areas. Different approaches in design, selection of building materials and construction technologies deployed in pursuit of disaster resiliency may cause undesirable adverse circumstances to the surroundings, which escalate its susceptibility to future calamities. Therefore, this paper aims to identify relevant key indicators which interpret construction sustainability in a post-disaster housing reconstruction context, and to further investigate the dynamic interactions of these indicators on the socio-ecological system to achieve holistic sustainable post-disaster housing reconstructions. Design/methodology/approach Methodology was divided into three main stages. The first stage involved content analysis of related research materials, whereas the second stage was allocated for empirical data collection from case study and interview sessions. Data obtained from the first and second stage were then used to develop a causal loop diagram in the third stage to identify dynamic interrelationships between the indicators and the variables within a post-disaster reconstruction system. Findings From our results, the nexus of sustainability and disaster resilience is apparent and it is imperative to comprehend their dynamic interactions. The impacts of post-disaster reconstructions on the socio-ecological system are significant. Therefore, the adaptation of integrated sustainable construction approach in the housing reconstruction practice through system thinking will foster a holistic approach in the decision-making process and could reduce environmental damage. This also strengthens the interrelated socio-ecological systems, thus reinforcing disaster resilience in the built environment. Originality/value This research looks into the adaptation of integrated sustainable construction approach in the housing reconstruction practice through systems thinking approach. This will foster a holistic approach in the decision-making process and could reduce environmental damage. This also strengthens the interrelated socio-ecological systems, thus reinforcing disaster resilience in the built environment. This paper also looks into identifying relevant key indicators that interpret construction sustainability, which incorporate environmental, social and economic factors pertaining to the context of post-disaster housing reconstruction in Kuala Krai, Kelantan. The dynamic interrelationships and causal impacts between the indicators with other variables within the system were also established.

Wastes are defined as those materials, substances, objects and products that are no longer of use to the consumer in terms of its original purpose, and are then disposed to the environment, usually as prescribed by the law. Based on a study in 2012, global municipal solid wastes (MSW) are expected to increase to approximately 2.2 billion tonnes per year in 2025 (Hoornweg and Bhada-Tata 2012). Wastewater, on the other hand, is also considered a global problem with many regions experiencing different issues: from water disease-related deaths in Africa and Asia to eutrophication in China and Europe (GEO5 2012). Another waste, for example, emissions of carbon dioxide (CO2) from anthropogenic sources, is reported to be one of the major causes of increase in the global mean temperature. These temperatures are expected to increase by 1.8–4.0 °C between 1980 and 2100 (IPCC 2007). Aside from being considered as consumers of environmental resources, mankind is also considered as producers or generators of wastes which has put a strain on the environment. When the environment is affected, this poses a question to the finiteness of our resources. This chapter focuses on solid wastes, waste management, and the significance of a Circular Economy (CE) to solid waste management.

In 2012, a total of 13.1 million tonnes of carbon dioxide were emitted by 14 airlines while transporting 72 per cent of international passengers into and out of Australia in 2012. With passenger and cargo traffic growing at between five to six per cent annually from 2013 to 2033, acquiring more fuel efficient aircraft to both renew the existing fleet and to service growth has the greatest potential in reducing emissions over the next 20 years. Our analysis shows that implementing carbon dioxide emissions abatement options such as installing light weight seats, iPad electronic flight bags, winglets, washing aircraft engines and reducing the number of engines used during taxiing, all offer net financial savings when considered over 20 years. Acquiring new fuel efficient aircraft has the biggest impact on emissions reduction. Low interest loans and longer loan repayment periods may incentivise airlines to acquire more fuel efficient aircraft to service traffic growth but other complimentary incentives and penalties are required to influence airlines to replace their current fleet with more fuel efficient aircraft.

Increasing environmental awareness has contributed to the shift of mindset among the Malaysian construction industry stakeholders. The Malaysian government has put an effort to prioritize the importance of managing construction and demolition (C&D) wastes to mitigate environmental impacts, but the recycling rate is still as low as 15%. This study was conducted to identify key principles and strategies in developing an integrated management of C&D waste via survey questionnaire sent to government agencies, developers, consultants and contractors. The final version of the survey involved 52 questions and it was sent to 480 construction actors. The results reveal that it is crucial that the process of managing the generation of C&D waste starts at the planning and designing stage so that the volume of generated waste could be decreased during the construction cycle. Suitable strategies for each stage of the construction cycle have been identified: among others, waste management plan and construction methods in the planning and designing stage; awareness and awards and regulations enhancement during procurement phase; and effective management during the stages of construction and demolition. A causal-loop diagram (CLD) for managing C&D waste was developed according to the findings
