This study examines who are the social actors in coordinating the environmental hot spots along the process of desalination. The integrated model design of life cycle modeling and Social Network Analysis is evaluated holistically by the inventory of life cycle and actor engagement ratings. Instances of the first small-scale reverse osmosis desalination plant project in Kelantan, Malaysia were used to meet the demands of this study. Environmental performance is measured through the Eco-Indicator 99 method in the Life Cycle Assessment Principles. Meanwhile, the network analysis of the actors’ networks involves stakeholders visualized through the UCINET software. The results show three hotspot points of membrane and brine disposal, the use of electrical energy, and the use of chemicals. The results acknowledged that 87 percent of the actors’ involvement from the dominant stakeholder group has been in control of the management and of the aforementioned hotspot. Undoubtedly, the results of this study can provide a better understanding of the potential market of actors to work with a more accurate and polycentric information flow for the development of more established desalination systems. This intriguing research will require further exploration in future studies.
Phosphorus (P) in the waste at Terengganu can be identified by the heterogeneity of waste sources present at the waste disposal collected, the technology used, location of disposal and the management depends on microbial waste decomposition operations. The diversion of phosphorus out of the waste disposal sites is associated with the presence of low phosphorus inflows due to reduction, recycling and waste recovery activities outside of the landfill system. This finding motivates the socioeconomic characterization of the actors (players) and the identification of management strategies developed by the stakeholders. Thus, the purpose of this study was to identify the nutrient element of phosphorus in the waste disposal site and investigate whether stakeholders were aware of phosphorus and phosphorus credit related to local economic circulars and to examine possible ways of managing phosphorus in the waste source by small waste players in Terengganu. The design of this study was qualitative, involving face-to-face interviews with the stakeholders and a corresponding analysis of their responses. The findings revealed lack of knowledge and awareness by actors regarding the element phosphorus, the causes and sources of phosphorus generation as well as the effects of phosphorus on environmental sustainability. This study highlights useful factors to guide future management decisions and educational programs as well as further research, to disseminate information concerning phosphorus recovery among actors involved in waste management at Terengganu.
Energy in maize productivity is an important parameter that is often used as a stabilization indicator in sustainable agricultural management. The production of maize contributed 25 percent of the total crop production in Terengganu, Malaysia. The purpose of this study is to examine the extent of the effectiveness of the Giddens Structural Theory-based Material Flow Analysis approach in creating an eco-friendly, sustainable and green economy through energy flow for maize production management. A total of 10 farms exceeding 50 hectares of land were involved as study samples, and the biomass energy from maize production waste was selected as a parameter of the study. The data was analyzed using the SubTANce Analysis (STAN) 2.5, ArcGIS and Microsoft Excel software packages. The results of the study show a continuous and significant relationship in the acquisition of biomass energy flow data in the proposed integrated framework model. These results support the fact that in the maize waste production the biomass energy balance data can be evaluated through a computational and correlative calculation method. The conclusion of this study also identified the change agents involved concretely in developing a more efficient and effective governance system for the management of maize productivity and its residual waste.
Environmental pollution in the pottery industry is a severe problem, particularly dust and smoke pollution from the building-pottery industry. The main objectives of this study are to quantify the carbon emissions and solid-waste generation from the life cycle of pottery production in Yunnan. This study was carried out between November 2020 and May 2021. LCA was used, and 1 kg of pottery was used as the functional unit. There is a lot of literature to obtain data on the carbon emissions and solid waste generated in the process of pottery production for reference and calculation. This study forces the extraction of raw materials to the processing point, the device boundary of the pottery-production process. Carbon emissions in the pottery-production process account for about 80% of the whole pottery life cycle. Moreover, a large amount of solid waste is mainly produced as a result of the waste and production process. It is recommended that the serious pollution-causing combustion system should be reformed. The enterprise’s waste can be recycled. Most of the waste products can only be used as construction filling, and a small amount of the waste products can be used as hard materials in proportion after crushing.
