I. INTRODUCTION The most important renewable resources are polysaccharides, sugars, and oils and fats. They are attractive alternatives to mineral oils as feedstocks for chemicals and could make a contribution to

Utilization of agricultural surpluses in some countries Broadening of the raw material basis for industrial purposes Development of new products Improvement of the world around us

One of their advantages is that they are renewable by agricultural methods within a short time.
