Level of awareness of stakeholders in the construction industry regarding the green building concept in Indonesia

The concept of green buildings evolved and gained momentum rapidly in all nations. Nearly 40% of total CO2 emissions and more than a third of global energy consumption come from the building and construction sector. The application of Green Building is recognized to reduce CO2 emissions and energy consumption. Awareness of the importance of implementing Green Building is needed to support the successful implementation of the Green Building concept. The purpose of this research is to analyse the level of awareness of stakeholders in construction (how well they understand green building and its regulations, how important they think green building is) and find out in what way they gain an understanding of the green building concept. Questionnaires were distributed to various stakeholders and analyzed with descriptive statistics. The result shows that Indonesian people who work in construction environments already know and are aware of the concept of Green Building. However, they still lack an understanding of regulations and consider government support necessary. Until now, they have gained an understanding of green buildings through lectures and the media.

Genealogy of Green Mining in Europe and Asia

The green mining concept is a consequence of the world’s commitment to realizing sustainable economic development. This aims to maintain the availability of natural resources in the future by minimizing environmental and social damage due to mining. This article aims to explain the genealogy of green mining in Europe and Asia, as well as conditions encourage the formation of green mining regulations. This is important, considering that Indonesia has abundant natural resources and is committed to accelerating green economybased downstream programs. It is hoped that this study can become a preference for natural resource management, especially mining, that prioritizes sustainability. Our research used literature studies starting from searching, collecting, evaluating and analyzing relevant sources according to the research topic. We found that there were differences in the background to the emergence of the concept of green mining in Europe and Asia. Green mining in Europe stems from public awareness of climate change due to environmentally unfriendly mining processes. So, this awareness gives birth to environmentally friendly policies in the mining process. Meanwhile, in Asia, the emergence of green mining is caused by international policies that pressure countries in Asia both politically and economically to implement green mining. This shows that green mining is related to the geopolitical and geoeconomic spectrum.

Hydrophobicity and performance analysis of beverage and agricultural waste torrefaction for high-grade bio-circular solid fuel

Torrefaction is recognized as a high-performance technology for converting raw biomass into high-grade solid biofuel. In this study, hydrophobic and ANOVA analyses were employed to investigate torrefied brewery waste, palm kernel shell, and water hyacinth residue. Herein, the torrefaction experiments were conducted at four temperatures (180, 230, 280, and 330 °C) for a residence time of 30 min. The biomass type and temperature were crucial in determining the optimum conditions for three response parameters: energy yield (EY), specific energy consumption (SEC), and hygroscopic reduction equilibrium (HRE). Hydrophobicity was assessed by measuring the contact angle (CA), and equilibrium moisture content (EMC) to represent hygroscopic behavior. The ANOVA results indicated that temperature had the most significant impact on the response parameters. Optimal torrefaction of brewery waste at 180 °C yielded an EY of 82.05 %, SEC of 81.88 kWh/kg, and HRE of 23.2 %. These findings highlight the advantages of biomass-derived torrefaction products in waste utilization, transport, and storage of biomass-derived torrefaction products. Furthermore, this study demonstrates an efficient method for enhancing the fuel quality of biomass, contributing significantly to the bio-circular green economy concept.

A multi-objective optimization approach for green supply chain network design for the sea cucumber (Apostichopus japonicus) industry

In China, aquatic supply chain network design does not include the green concept or the coordination of environmental and economic performance. Sea cucumber (Apostichopus japonicus) is an aquatic product of high economic value; however, studies on sea cucumber supply chain network optimization are lacking. This study is the first to design the sea cucumber supply chain and construct an optimization model. Considering the characteristics of the sea cucumber industry, LCA for Experts software and the CML-IA-Aug. 2016-world method were used to assess each aquaculture model's global warming potential (GWP), as the environmental performance indicator. In addition, multi-objective genetic algorithm (MOGA) coupled with Modified Technique for Order of Preference by Similarity to Ideal Solution (M-TOPSIS) integrates yield production, economic benefits, and environmental performance. The results demonstrated that cage seed rearing (CSR) combined bottom sowing aquaculture (BSA) represents the best production strategy upstream of the sea cucumber supply chain. In the downstream, the best proportion of sales channels in supermarkets, boutique stores and online shops accounted for 14.79 %, 58.02 % and 27.19 % of the production, respectively. The proposed optimization scenario 4 (S4) can increase product profit by 27.88 % and reduce GWP by 56.89 %. The following improvement measures are proposed: using sea cucumber aquaculture industry standards (cleaner production and green supplier selection) to regulate the behavior of enterprises, adopting an ecological and green production strategy, eliminating high-energy consumption and high emission production practices, and promoting widespread adoption of green consumption concepts. Finally, these measures may improve the sea cucumber supply chain, achieve coordinated environmental and economic performance development in the sea cucumber industry, and provide guidance for green optimization of other aquatic product supply chains in China.

Analysis of Evolving Carbon Stock Trends and Influencing Factors in Chongqing under Future Scenarios

The relationship between land use changes and regional carbon storage is closely linked. Identifying evolving trends concerning and influencing factors on carbon storage under future scenarios is key in order to achieve the “dual carbon” goals. Using Chongqing as a case study, this study integrated the advantages of the PLUS model, InVEST model, and a geographic detector model. It conducted simulations of land use type data under scenarios of natural development (ND) and ecological protection (EP), and identified evolving trends and influencing factors regarding carbon storage. The results were as follows: (1) the PLUS model demonstrated excellent simulation performance, with a Kappa coefficient above 0.85 and an overall accuracy above 0.90. During the study period, significant changes occurred for cultivated land, forested land, water bodies, and construction, which were closely related to carbon storage; (2) carbon storage in Chongqing showed a decreasing trend, with a decrease of 10.07 × 106 t C from 2000 to 2020. Under the ND scenario, carbon storage was projected to decrease by 10.54 × 106 t C in 2030 compared to 2020, and it was expected to stabilize from 2030 to 2050. At the county level, Youyang, Fengjie, and Wuxi had the highest carbon storage, while Nanchuan, Jiangbei, and Dadukou had the lowest; (3) the spatial distribution of carbon storage presented an “eastern hotspot western cold spot aggregation” pattern. The proportions of regions with a decreased, unchanged, and increased aggregation of carbon storage in Chongqing during 2000–2010 and 2010–2020 were 2.99%, 95.95%, 1.06%; and 4.39%, 92.40%, 3.21%, respectively. The trend indicated a decrease in the aggregation of carbon storage, and future carbon storage was expected to stabilize; (4) elevation, terrain fluctuation, NDVI, annual average temperature, annual average precipitation, and nighttime light index had influence values of 0.88, 0.81, 0.61, 0.86, 0.77, and 0.81 on carbon storage, respectively, with different combinations of influencing factors having a greater impact. In the future, ecological priority and green development concepts should be followed, and comprehensive improvement of regional development conditions should be pursued to enhance carbon storage, thereby promoting the achievement of the “dual carbon” goals. This study provided an analytical path and data support for formulating optimized carbon storage policies at the regional level.

Research on environment and sustainable development education under the background of green ecology

Abstract The implementation of environmental and sustainable development goal (SDG) education helps to cultivate people's awareness of environmental protection and the concept of SDG, and is conducive to the protection and management of the environment. However, due to the weak awareness of education and lack of environmental protection knowledge in the environment and SDG education, environmental protection work has been affected. Therefore, this article proposed the implementation strategy of environment and SDG education from the perspective of green ecology. This research utilized datasets agricultural biomass accumulated from five cities of Guandong (i.e., Foshan [F], Heshan [H], Nanxiong [N], and Shantou [S]) province, China. Through experimental research, the utilization rate of agricultural waste and utilization ratio of straw was explored by using data envelopment analysis, and then, the environmental awareness of students and the environmental education level of teachers under the environmental and SDG education strategies of green ecological concept were combined. The results showed that the proportion of straw waste biomass utilization in S city was the highest among the four cities; the implementation strategy of environment and SDG education proposed in this article can enhance students’ awareness of environmental protection by 5.21% and improve environmental education level of teachers by 9.51%.

University Social Responsibilities-Based Green Accounting: Implementation of Green Universities

The research aims to examine the differences in the implementation of green accounting based on University Social Responsibilities (USR) at the Sepuluh Nopember Institute of Technology (ITS) and Brawijaya University (UB). The data analysis method uses a different test approach with a sample size of 150 respondents from the academic community. The data collection method uses a mail survey with Google Forms. The research results prove no difference in implementing environmental awareness, environmental involvement, environmental reporting, environmental audit, and university social responsibility at ITS and UB. UB initiated the green campus concept and ITS with the eco campus concept. However, there are no audit reports related to green accounting at either campus. The contribution of this research will lead to policies for drafting environmental audit report regulations because campuses also produce waste from the impact of their activities. This regulation can strengthen sustainable practices on campus environments in Indonesia and ensure a sustainable environmental legacy for future generations.

A Divestment Model: Migration to Green Energy Investment Portfolio Concept

In a targeted terminal wealth generated by bond and risky assets, where the proportion of a risky asset is gradually being phased down, we propose a divestment model in a risky asset compensated by growth in a bond (insurance). The model includes the phase-down rate of the risky asset, c(t), the variable proportion, π(t), in a risky asset and the interest rate, r, of the bond. To guide the growth of the total wealth in this study, we compared it to the Øksendal and Sulem (Backward Stochastic Differential Equations and Risk Measures (2019)) total wealth for which c(t)=0, and π(t) is a constant. We employed the Fokker–Planck equation to find the variable moment, π(t), and the associated variance. We proved the existence and uniqueness of the first moment by Feller’s criteria. We have found a pair (c*(t),r*) for each π(t), which guarantees a growing total wealth. We have addressed the question whether this pair can reasonably be achieved to ensure an acceptable phase-down rate at a financially achievable interest rate, r*.
