The European Union defines waste as any object that is discarded, intended to be discarded, or required to be discarded, even though it might still have potential use. The quantity of waste generated is escalating daily, posing a significant concern globally. There is no single solution to curtail or prevent this escalation; however, sustainable practices such as reusing and recycling offer the most viable approach. Currently, numerous initiatives focus on recycling waste into diverse products, such as bricks. Notably, the chemical waste, known as sludge, from an Oleochemical industry in Malaysia has shown promising potential for recycling into bricks. Thus, this paper aims to simulate brick production based on industry sludge waste for an upscaling strategy utilizing the Discrete Event Simulation technique. The Discrete Event Simulation (DES) technique was selected due to its suitability for modelling business processes. The simulation process starts by modelling the actual process flow of brick production as a DES model using AnyLogic 6.0. Next, various test scenarios have been simulated to identify bottlenecks and constraints in brick production. The result analysis revealed that the daily consumption of sludge per unit of brick production significantly impacts the process. The quantity of sludge utilized per brick produced was relatively minimal compared to the daily sludge output by the industry. This discovery holds importance in preparing the industry for potential upscaling strategies, facilitating the achievement of the zero-waste target by 2030.

摘要

The European Union defines waste as any object that is discarded, intended to be discarded, or required to be discarded, even though it might still have potential use. The quantity of waste generated is escalating daily, posing a significant concern globally. There is no single solution to curtail or prevent this escalation; however, sustainable practices such as reusing and recycling offer the most viable approach. Currently, numerous initiatives focus on recycling waste into diverse products, such as bricks. Notably, the chemical waste, known as sludge, from an Oleochemical industry in Malaysia has shown promising potential for recycling into bricks. Thus, this paper aims to simulate brick production based on industry sludge waste for an upscaling strategy utilizing the Discrete Event Simulation technique. The Discrete Event Simulation (DES) technique was selected due to its suitability for modelling business processes. The simulation process starts by modelling the actual process flow of brick production as a DES model using AnyLogic 6.0. Next, various test scenarios have been simulated to identify bottlenecks and constraints in brick production. The result analysis revealed that the daily consumption of sludge per unit of brick production significantly impacts the process. The quantity of sludge utilized per brick produced was relatively minimal compared to the daily sludge output by the industry. This discovery holds importance in preparing the industry for potential upscaling strategies, facilitating the achievement of the zero-waste target by 2030.
