performance evaluation of masonry grout containing high volume of palm Oil Industry by products
Journal of Cleaner Production, 2019Co-Authors: Ramappa Ramesh Nayaka, Mohd Zamin Jumaat, Johnson U Alengaram, Sumiani Yusoff, Reventheran GanasanAbstract:Abstract The rapid depletion of natural resources has led to the need to develop sustainable practices and material in various applications. One such sustainable practice is to divert the waste generated in the palm Oil Industry into production of building materials. In this study, palm Oil clinker (POC) is used to replace cement and coarse aggregate. The POC chunks are crushed to be used as coarse aggregate and further ground to produce POC powder (POCP) to be used as a binder. The physical properties, chemical composition and scanning electronic microscopic studies were conducted to check the feasibility of substitution of up to 50% POCP as binder and up to 100% POC as coarse aggregate. Density, ultrsonic pulse velocity(UPV), compressive strength for air & water curing, flexural, tensile strength, modulus of elasticity in water cured regimes and structural efficiency were evaluated for the samples. Carbon footprint, cost effieciency and energy savings were also evaluated to understand the contribution of POC to sustainability. The results revealed that the ideal mixture of GPP (30% POCP & 50% POC) masonry grout achieved 79% of compressive strength, a 83% of flexural strength, 85% of tensile strength and about 85.5% of modulus elasticity, as compared to control masonry grout. Carbon emissions of GPP was reduced by 21% and 14.60% cost reduction was established, in addition, appreciable energy savings was notified. The study showed that that utilisation of POC as eco-friendly material in masonry grout is highly recommended based on performance and can provide a route to sustanable practices in the building Industry.

high strength lightweight aggregate concrete using blended coarse lightweight aggregate origin from palm Oil Industry
Sains Malaysia, 2017Co-Authors: Muhammad Aslam, Payam Shafigh, Mohd Zamin JumaatAbstract:The benefits of using structural lightweight concrete in construction Industry, particularly in high rise buildings, over normal weight concrete are numerous. The main method of producing structural lightweight concrete is the use of lightweight aggregates instead of ordinary aggregates in concrete. Due to the limited resources for natural and artificial lightweight aggregates, the alternative sources for lightweight aggregates should be discovered from industrial wastes. Oil palm shell (OPS) and Oil-palm-bOiler clinker (OPBC) are two solid wastes from palm Oil Industry and are available in abundance in tropical regimes. The use of just OPS as coarse lightweight aggregate in concrete mixture has some drawbacks for concrete. The aim of this study was to investigate engineering properties of a lightweight concrete containing both of these aggregates. For this purpose, in this study, 50% (by volume) of OPS was replaced with OPBC in an OPS lightweight concrete. The test results showed that when OPS was substituted with OPBC, significant improvement was observed in the compressive, splitting tensile and flexural strengths. In addition, initial and final water absorption as well as drying shrinkage strain of blended coarse lightweight aggregate concrete were significantly less than OPS concrete.

structural lightweight aggregate concrete using two types of waste from the palm Oil Industry as aggregate
Journal of Cleaner Production, 2014Co-Authors: Payam Shafigh, Mohd Zamin Jumaat, Hilmi Bin Mahmud, Rasel Ahmmad, Syamsul BahriAbstract:Abstract Huge quantities of raw materials are used in making concrete. Due to the limitations of natural materials the use of waste and by-product materials in concrete can eliminate the negative impact of concrete on the environment. To produce a cleaner and greener concrete two waste materials from the palm Oil Industry were used as coarse and fine aggregates. For this purpose normal sand was replaced with Oil-palm-bOiler clinker (OPBC) sand from 0 to 50% in Oil palm shell (OPS) lightweight aggregate concrete. Properties, including workability, different types of density, compressive strength in different curing regimes, splitting tensile and flexural strengths, stress–strain curve, modulus of elasticity, water absorption and drying shrinkage strain of green lightweight concretes, were measured and discussed. The results showed that it is possible to produce environmentally-friendly structural lightweight concrete by incorporating high volume waste lightweight aggregates from the palm Oil Industry.

e supply chain management value concept for the palm Oil Industry
Journal of Information Systems, 2019Co-Authors: Muhamad Akbar, Antoni DariusAbstract:The harmony of information technology (IT) and business is an asset and the foundation of the organizations to improve and build business competitive strategies. There is a need to integrate and coordinate all business partners of the organization, particularly those associated with information technology and suppliers, raw materials or resources needed in the supply chain management. The effectiveness of an electronic supply chain management (E-SCM) in the palm Oil Industry will be the crucial factor to provide the organization with business opportunities and improve competitive position in the marketplace. This study aims to investigate critical factors E -Supply Chain Management in Oil palm Industry through Theory Resource-Based View (RBV). With RBV theory, this study develops a concept that can be utilized for identifying the criticalsuccess factors of E-SCM value in palm Oil Industry. The quantitative research method is used for collecting data in four Palm Oil organizations in South Sumatera. This research reveals that IT human resources and IT infrastructure are the critical factors and capability to operate E-SCM effectively and efficiently

exploring the potential of carbon capture and storage enhanced Oil recovery as a mitigation strategy in the colombian Oil Industry
International Journal of Greenhouse Gas Control, 2020Co-Authors: Edgar Yanez, Andrea Ramirez, Vanessa Nunezlopez, Edgar Castillo, Andre FaaijAbstract:Abstract The use of CO2 for enhanced Oil recovery (CO2-EOR) is a promising alternative for reducing the cost of carbon capture and storage (CCS). In this study the techno-economic potential of integrated CCS-EOR projects for reducing greenhouse gas (GHG) emissions in the Colombian Oil Industry is estimated. For this purpose, a source-sink matching process is carried out, including CO2 capture potentials in sources from the petroleum, cement, power generation, and bioethanol industries, as well as from the CO2 storage in suitable Oil fields for EOR. The results indicate that a total of 142 million tons of carbon dioxide (MtCO2) could be stored, while delivering 465 MMbbl through five CCS-EOR projects in four clusters identified around the country. The levelised cost for capture ranged between 12–209 €/tCO2, followed by the cost of CO2 during EOR operations with a variation of 24–59 €/tCO2, and finally the CO2 transport, from 1 €/tCO2 to 23 €/tCO2. The CO2 mitigation potential of CCS-EOR represents 25 % of the forecasted Oil Industry emissions in Colombia for the period of 2025–2040. As compared to the intended nationally determined contribution (INDC) target set by the Colombian government, CCS-EOR projects could contribute 7 % of the total accumulated emissions reductions by 2040.
