The winner of Entrepreneur's College Entrepreneur of 2012 is Bryan Silverman, a Duke University student and co-founder Star Toilet Paper. With just $1,000 in startup funds, Silverman and his brother launched the Durham, N.C. and Ann Arbor, Mich.-based, company, which sells advertisements on toilet paper. Star buys recycled toilet tissue rolls in bulk wholesale and has a printer -- using vegetable oil-based ink -- place coupons on the top ply. So far, more than 65 companies have taken the plunge and marketed their services through the toilet-paper advertiser.
