Congratulations to you and to your partners.The company is producing about 40.000 ton biodiesel per year using inorganic catalysis. Mr. Pettas wants to examine the case of making the absolutely necessary changes in order to alternatively use inorganic or enzyme catalysis for biodiesel production with minor changes in
