This study explored the relationship between the motivational potential characteristics of a job (measured by motivating potential scores or MPS) and job satisfaction and the moderation effect of personality traits. The results showed that the agreeableness personality trait could not significantly predict job satisfaction. However, the higher the MPS and the higher the agreeableness among the employees, the higher the job satisfaction tendency. Conscientiousness and job satisfaction had a significantly positive correlation. The interaction between MPS and conscientiousness also had a significantly positive impact on job satisfaction. The results showed that job satisfaction tended to decline under the interaction of MPS and extraversion. In addition, the interaction of MPS with neuroticism also had a significant effect on job satisfaction. The interaction between MPS and openness to experience had no significant effect on job satisfaction. However, the higher the MPS and the higher the openness of experience of the worker, the higher the job satisfaction.

A new sludge processing method was developed by the Beta Company, a paper manufacturing company. The new method will shorten the time for transforming sludge into organic fertilizers, which will improve the process of handling the waste generated by a paper manufacturing company. The paper industry is facing the most rigorous regulations for processing wastewater and sludge to date in the history of many industrialized and developing countries. The Beta Company attempted to improve the conventional method implemented in-company for handling sludge generated during the paper manufacturing process, instead of shipping sludge out-of- company for processing by a third party. The current experimental results show positive improvement, indicating the Beta Company is moving one step closer toward environmental sustainability commitments.
