Smart homes leverage advanced technologies to optimize energy consumption and enhance sustainability through interconnected devices and sophisticated...
Hard-to-abate industries such as cement, steel, and chemical production are major contributors to carbon dioxide (CO2) emissions due to its energy intensive and hard-to-abate nature. The high-temperature process during the conversion of limestone into clinker in cement production results in significant process emissions. To achieve net-zero emission target, the industries are...
Composting has become a widely adopted alternative to landfilling for food waste management, offering significant environmental benefits by reducing waste and mitigating climate change. This study focuses on enhancing the efficiency of food waste composting by applying mathematical modelling to better understand the underlying biological and physiochemical mechanisms. First-order...
This paper presents a methodology for integrating a polygeneration network with an integrated renewable energy supply chain network and an interplant heat and mass exchange network using a centralized hub layout approach. The method involves developing a three-layered superstructure. The first layer consists of bio-based renewable energy sources connected to the second layer...
Given the urgency to transition to low carbon future, oil refineries need to identify feasible strategies for decarbonisation. One way to address this is by integrating renewable energy systems. However, the high initial costs and intermittency appeared to be the key barriers for the adoption of renewable energy technologies. Hence, a multi-period optimisation model is developed...
Energy is typically generated from fossil fuels, leading to significant greenhouse gas (GHG) emissions. Therefore, cleaner energy needs to be used to reduce GHG emissions in the energy sector. Hydrogen (H2) is identified as a potential resource suitable for replacing fossil fuels as H2 burns with oxygen to produce water (H2O) and generates no emissions as a result of this...
A peer-to-peer energy sharing system, aiming to achieve emissions reduction by generating and sharing renewable energy among participants, has emerged as an appealing solution for addressing carbon emissions attributed to energy consumption. However, the resiliency of the peer-to-peer energy sharing system, particularly in addressing the risks of disruptions, has yet to be...
Circular economy (CE) appears to be a plausible strategy to reduce emissions and enhance sustainability for the heavy-emitting sector including the oil and gas sector. This works explores the feasibility of waste oil (WO) re-refinery pathways. Given that the moisture content of the WO plays an important role in the production cost and product quality, the impact of the moisture...
Photovoltaic (PV) installations have traditionally relied on a conventional south-facing orientation, which maximizes energy production at noon but has lower energy generation in the morning and afternoon. Vertical photovoltaic (VPV) systems have emerged as promising alternatives to address this inconsistency. Vertical photovoltaic systems can enhance energy generation by facing...
To ensure the optimum performance of downstream processes in a petrochemical refinery, the operation of a vacuum distillation unit (VDU) is critical. It needs to satisfy the yield and quality requirements of the downstream process. Otherwise, it will result in a loss of profitability in the refinery. Hence, it is important to optimise the operation of the VDU to ensure optimum...
The tremendous production of fish has resulted in an increased fish waste generation, which ultimately led to the current triple planetary crises on climate, biodiversity, and pollution. In this study, a Fish Waste-based Eco-Industrial Park (FWEIP) model is developed in an attempt to convert the linear economy in existing fish waste management into a circular economy model...
This paper presents a study on the synthesis and optimisation of a renewable energy and resource supply chain network (SCN) to satisfy agricultural greenhouse resource and energy demands. This is motivated by the high costs and emissions to run greenhouses due to the resources and energy required for optimal growth conditions. The investigation aims to contribute to the growing...
Agriculture is an essential economic sector as it plays an important role in providing growing populations with sufficient food. Thus, it is imperative for policymakers to plan sufficient food stockpiles based on consumption requirements while ensuring lands are used in an efficient manner for producing a range of crops. Land is a limited resource and should be utilised...
Heat transfer enhancement has been used to achieve lower heat transfer area and reduced utility requirements in heat exchanger network synthesis problems involving retrofit. This paper presents a technique for implementing heat transfer enhancements in both grassroot and retrofit heat exchanger network synthesis problems involving multiperiod operations. For the grassroot...
The coordinated integration of agricultural and industrial processes in plant-derived production can offer a solution toward sustainability. However, it is hard for general practitioners to realize the coordinated integration of these processes just based on the precedent fact. A special form clarifying the functions of the required activities should be shared among the...
Selecting the suppliers in a green supply chain (GSC) improves supply chain capabilities by considering environmental policies. On the other hand, considering the development of technology and intelligence of the Internet of Things (IoT) and their help to meet goals better, it is essential to study them in this area. So, it is crucial to identify the influential factors of the...
Over 13% of the global population (most of which are rural communities) still lack access to electricity. A typical resolution to this would be to generate more electricity from existing power generation infrastructure. However, the urgency to meet net-zero global greenhouse gas emissions means that this resolution may not be the way forward. Instead, policymakers must consider...
Agricultural biomass is one of the major wastes in the world. Most of these wastes end up in landfills and incineration, causing significant environmental problems that are detrimental to human health and other species on the Earth. Thermochemical conversion can solve this issue by utilizing the energy embedded inside the biomass, mainly organic matter, into high-grade fuels and...
In the midst of a climate crisis, alternative and low-carbon energy resources must be put to scale in order to achieve carbon emission reductions in the coming decades. In this respect, hydrogen has gained attention as an alternative energy carrier. Hydrogen can be produced from methods that are commonly classified by a range of colours. However, each hydrogen source has its own...
While the uncertainty brought about by a varying feed mineralogy was taken into consideration, the paper investigated the modeling and prediction of the leaching behavior of complex copper-cobalt bearing ores, using an artificial neural network (ANN) with a backforward algorithm. The process optimization is further conducted using the response surface methodology (RSM) employing...
