(A product a day! Food for thought on: 1. The raw materials - Where can I find this raw material? Locally or imported? Cost? 2. The process - What kind of process? Chemical, physical, biological? Cost and safety considerations? If there are a number of alternative processes, which is the most energy efficient, most cost effective, and safest? 3. The product - What will the product be used for? Where will it be marketed? Locally or exported? How much profit will I make?)
