multi products productions from malaysian oil palm empty fruit bunch efb analyzing economic potentials from the optimal Biomass Supply Chain
Journal of Cleaner Production, 2017Co-Authors: Abdulhalim Abdulrazik, Mohamed Elsholkami, Ali Elkamel, Leonardo SimonAbstract:The economic potentials of Malaysian oil palm empty fruit bunch are realized by several motivating factors such as abundance, cheapness and are generally feasible to produce multi-products that range from energy, chemicals and materials. Amid continuing supports from the government in terms of policies, strategies and funding, manufacturing planning and decision to utilize this Biomass resource requires a decision-support tool. In this regard, Biomass Supply Chain modeling serves as the supportive tool and can provide economic indications for guided future investments. Sequential steps in modeling and optimization of the Supply Chain that utilized empty fruit bunch were shown. In a form of superstructure, the Supply Chain consisted processing stages for converting the Biomass into intermediates and products, transportation networks that used truck, train or pipeline, and the options for product's direct sales or for further refinements. The developed optimization model has considered Biomass cost, production costs, transportation costs, and emission treatment costs from transportation and production activities in order to determine the annual profit. By taking a case study of Peninsula Malaysia, optimal value showed a profit of $ 713,642,269/y could be achieved which has assumed a single ownership for all of the facilities in the Supply Chain. Besides, the tabulated values of yields and emission levels could provide comparative analysis between the processing routes. Sensitivity analysis was then performed to perturb the approximated parameters or data that have been used in this study.

water energy nexus and greenhouse gas sulfur oxides embodied emissions of Biomass Supply and production system a large scale analysis using combined life cycle and dynamic simulation approach
Energy Conversion and Management, 2020Co-Authors: Seyed Mojib Zahraee, Saeed Rahimpour Golroudbary, Nirajan Shiwakoti, Peter Stasinopoulos, Andrzej KraslawskiAbstract:Abstract The achievement of low or zero greenhouse gas and particulate matter emissions such as sulfur oxides, optimized water-energy nexus, and a well-protected environment are challenges that have become increasingly significant for the Biomass industry. There is a need to conduct evaluation and analyses of the greenhouse gas and particulate emissions, water use and energy consumption of Biomass process and delivery, from “cradle to gate”. Therefore, to fill this noted gap in the literature, this study aims to develop a combined life cycle and dynamic simulation model to examine water-energy nexus in the Biomass industry, particularly under uncertainties, as well as estimation of greenhouse gas and particulate matter emissions of the Biomass Supply Chain by 2050. The dynamic modelling of material, energy, and water flows was used to perform those tasks. An in-depth analysis of environmental issues during the production, processing, conversion and delivery of empty fruit bunches Biomass Supply and production system is conducted. The model was tested and implemented through a case study of three main Biomass suppliers in Malaysia. Comparison of environmental performance of the production stages of 31 products through pre-processed, intermediate, and final productions in the Biomass Supply Chain shows that bio-compost, activated-carbon, and cellulose are the highest water users and energy consumers as well as the highest emitters of greenhouse gas and sulfur oxides for all the three suppliers. Sensitivity analysis was also conducted for these critical products based on recent governmental land and demand policies. The main finding of this paper indicates a need for a well-planned management of water-energy nexus in pre-processed production compared to intermediate and final production of Biomass Supply Chain. This finding provides valuable insights to the government agencies and stakeholders to pursue sustainable bioenergy development strategies.

transportation system analysis of empty fruit bunches Biomass Supply Chain based on delivery cost and greenhouse gas emissions
Procedia Manufacturing, 2020Co-Authors: Seyed Mojib Zahraee, Saeed Rahimpour Golroudbary, Nirajan Shiwakoti, Peter Stasinopoulos, Andrzej KraslawskiAbstract:Abstract The future of sustainable energy Supply and production is moving toward the use of renewable sources like Biomass. It is important to develop sustainable Biomass Supply Chain (BSC) by enhancing energy security, decreasing air pollution, and reduction of total cost. The main barriers in the sustainable development of BSC are transportation cost and greenhouse gas (GHG) emissions that represent substantial proportion of the total cost of the BSC. This paper aims to examine the delivery cost and GHG emissions of different transportation modes (train and truck) of oil palm empty fruit bunches (EFB) Biomass Supply Chain. To achieve this goal, we used the data of three EFB suppliers in Malaysia as a case study. We then developed a dynamic simulation model using AnyLogic software to predict the delivery cost and greenhouse gas emissions. Results showed that the highest GHG emissions were associated with train transportation mode while it was lowest with truck. Cost analysis showed that highest cumulative transportation cost is associated with truck while train has the lowest cumulative transportation costs. These results highlight the opportunity for decision makers to minimize the delivery cost and GHG emissions by optimizing the transportation systems for BSC.

Biomass Supply Chain environmental and socio economic analysis 40 years comprehensive review of methods decision issues sustainability challenges and the way forward
Biomass & Bioenergy, 2020Co-Authors: Seyed Mojib Zahraee, Nirajan Shiwakoti, Peter StasinopoulosAbstract:Abstract Biomass is a valuable renewable source of energy as an alternative to fossil fuels. The main barriers in Biomass and biofuel development are feedstock high cost, lack of reliable Supply, and uncertainties. A systematic review of comprehensive solution tools to overcome the Biomass Supply Chain (BSC) planning challenges is critical for both academic research and industry. Therefore, the aim of this study is to conduct a systematic review of BSC modeling and optimization and identify future research directions. We reviewed 300 papers that have been published in the past 40 years on this topic to assess the various models of BSCs, their objective functions, solution approaches, and decision levels employed. Results show that researchers are motivated to use mixed integer programming models for BSC problems because of the complexities of nonlinear models, as well as the simplicity of the linear approaches. There is a lack of multi-objective optimization approaches to address the economic, social, and environmental issues simultaneously in BSC. Although factors such as the political regulation, governmental subsidy, impact of Biomass and oil price and cost of raw material are uncertain, most studies formally treat only the Supply and demand of Biomass as uncertain parameters. It is highly recommended that an integrated and holistic model that consider all facilities in the whole BSC be developed and tested with real data. In addition, incorporating strategic, tactical, and operational decision levels in the model is suggested to address the challenges of incorporating day-to-day inventory control and fleet management issues.

Performance Evaluation of EFB Biomass Supply Chain for Electricity Power Generation Based on Computer Simulation: Malaysia Case Study
Advances in Material Sciences and Engineering, 2020Co-Authors: Seyed Mojib Zahraee, Ali Tolooie, Ainul Akmar Mokhtar, Nurul Afiqah Mohd AsriAbstract:Malaysia is one of the largest countries that has the largest palm oil plantation size in the world. Despite the enormous amount of palm Biomass in the state, the use of Biomass as fuel for power generation remains low. One of the most significant crises in energy Supply from the Biomass is to utilize it efficiently and effectively by considering lower cost of the Supply Chain and the process to change the Biomass into useful energy source. In this paper, computer simulation is used to develop a model form current situation of empty fruit bunches (EFB) Biomass Supply Chain in Perak sate of Malaysia based on Arena software. The results found that, there are sixteen potential palm oil sites that had been analysed and met all the criteria of the case study according to their existing palm oil capacity, distance to the nearest power plant and minimum palm oil produced. The model had also been run with two different scenarios by decreasing the number of labour and increasing the number of trucks. First scenario showed that by decreasing the labors, output is decreased from 4.59 to 4.336 ton/ha. In contrast, cycle time, value added (VA) time and other time are increased near 15, 25 and 15% respectively. Additionally, the final results based on the second scenario claimed that by assigning two truck, the output of the process is increased 23% (from 4.59 to 6.02 ton/ha) compared to current situation as well as the time cycle of the whole process is increased from 7.2 to 8.95 h because of an increase in VA and Other time (34 and 23%).
