HP says it has found a way to reduce notebook packaging materials by 97 percent, and cut transportation costs by 31 percent. The computer giant has won Walmart's "green" Home Entertainment Design Challenge, by packaging a Pavillion dv6929 in a messenger bag capable of doubling as a shipping container. As a result, less styrofoam and cardboard are consumed, and a bulk shipment can occupy less space in ships and trucks, in theory resulting in less fuel expenses.

Walmart claims to be pushing towards environmental sustainability, and has called on suppliers to cut back on plastic and cardboard packaging schemes. HP says that while its messenger-bag pilot program will not save money initially because of development costs, benefits could be substantial in widespread use. This will not carry over to shoppers however, who will be expected to pay a "negligible" increased price.

The bag is described as tan and canvas-like, with an "aqua" theme featuring a blue and green design on the front. The case is made from 100 percent recycled material, according to HP.
