Abstract The present work aims to analyse the environmental advantages of a production process that applies circular economy. The study examines a product that is generated through the use of a certain percentage of recovered secondary materials, thus helping to avoid impacts related to the disposal of these materials and preserving the ecosystems from indiscriminate excessive natural resources extraction. The product analysed is an ecological detergent (“Ri-Detersivo” – Re-Detergent), produced by the company Tea Natura, mainly composed of regenerated vegetable oils coming from food industry. The methodology used in this paper is Life Cycle Assessment (LCA). A partial LCA will be carried out here, arriving at the saponification phase, and comparing the environmental impacts deriving from the Re-Detergent production process with those of a traditional soap, comparable to that studied in terms of function. The analysis of the case study found that the use of regenerated vegetable oils for the production of soap allows to significantly reduce the environmental impacts compared to the use of coconut oil imported from third countries.

Resource Needs

Nikolai Asia Pacific in Johor Bahru Malaysia is a leading manufacturer of vegetable oils and fats. The Senior Manager of Human Resource and Organization Development (HROD) had concerns about employees at managerial levels. He felt that they were not playing their role in championing organizational changes being made for improvement in performance. He expected the managers should be able to foresee the struggles the organization will face in the coming years and initiate changes even when everything seemed to be going well. This case presents an opportunity for first-year undergraduate students to understand needs assessment for training and non-training interventions for managers of an organization. The case discusses issues of performance discrepancies among managers despite the various initiatives taken by the HROD department. In order to emulate reality, the event that led the HROD to take action has been recorded in the case study. The identified gaps will prompt learners to identify tools and approaches necessary in such a situation.

Fluid Properties

Various vegetable oils were widely used as a lubricant in machining since 1990‘s. However during machining of various materials, various vegetable oils gave superior performance related to other oils which is due to their individual thermo physical properties. So that the prediction of influencing properties of various vegetable oils novel technique. Therefore in the present work turning of AISI 304 steel with carbide tool is taken as a case study for ascertaining the influence of vegetable oil properties in the machining environment. Among the fluid properties, properties such as viscosity, thermal conductivity, density and specific heat are taken for optimization. For optimization of fluid properties initially DOE Technique has been adopted, using which L16 orthogonal array has been formed for carrying out the simulations. CFD analysis with proper boundary conditions has been adopted for predictions the generated temperature at a constant distance from tool tip. From the obtained results, it is perceived that thermal conductivity is performed a major role to reducing of generated temperature within the tool followed by viscosity and specific heat whereas effect of density on generated temperature is found to be least significant. Therefore the present work highlights the combinations of DOE approach and CFD analysis in predicting the influence of vegetable oil properties and their values in the machining environment
