government and private customers.

• Sell fertilizer according to the customers needs.
• Support customer to improve quality of fertilizers to suit with their environmental.
• Ensure the fertilizers quality before delivering to customers.

• Presenting and selling life insurance policies and health insurance policies to the customers.
• Studying, learning and improving both attitudes towards customers and oneself in selling insurance.

• Phenol synthesis from lignin degradation.

(Study of phenol formation from lignin degradation by various reactions in a reactor on heavy metal catalyst and study the statistical results using the BOX BEHNKEN DESIGN method to determine the factors affecting phenol formation.)
