Hoping to uncover the nation's next crop of promising entrepreneurs, Fortune Magazine held their fifth annual business plan competition. The winners were announced in the November issue of the magazine.

Entrants were judged on the strength and viability of their business plan through three rounds of competition. The top spots of this year's contest were all environmentally themed products.

This year's top prize went to Mullis Enterprises for their pet-safe pesticide "Green Dragon Roach Kill."

Jay Mullis started Green Dragon with $63,000 he made from previous business plan competitions. Mullis said he got the recipe from his grandfather who was a successful pest-control business owner in Georgia.

When placed in cabinets and behind appliances, Green Dragon dehydrates and kills household insects via its primary agent, boric acid. It contains all the sweet and sour flavors cockroaches thrive on but yields the same toxicity as table salt.

Mullis currently has orders from pest-control firms totaling $200,000.

"Customers are asking for a green solution," he said, "and I've got it."

Second place went Dhyaneshwar and Ajay Chawan, the father-son team behind Saatwic Foods. The Chawan's business plan revolved around their method of Carbostar, which is essentially a refined-- but not modified-- starch cell that can be utilized in any processed food. It acts to prevent rapid digestion of carbohydrates and is scientifically proven to reduce the calories from carbohydrates by 50 percent; that's all the food and half the calories. It also acts to reduce the glycemic impact by 35 percent, making foods that were formerly inaccessible to people diagnosed with diabetes (potato chips, pizza crusts, etc.) edible. On top of that, it more than doubles a food's fiber.

Carbostar's ingredients are USDA approved for organic foods and have no known side effects. While much of the $600,000 Ajay received from an angel investor has gone directly to research, and Carbostar foods has yet to reach grocery store shelves, Saatwic Foods have made deals with General Foods, Heinz, and Kellogg's. Projected sales for 2008 total $896,000.

All participants in Fortune's Business Plan contest have to be American citizens and at least 18 years old.
