A VEHICLE MOUNTED BAIT DISPENSER

A 3-inch-diameter plastic tube mounted on a truck was designed for distributing bait (cut carrots or grain) for mammal control. Baits are fed into the tube by an operator standing in the truck bed. The device is light-weight and detachable and permits rapid, accurate placement of bait along a line on the ground or in a plowed furrow.

Comparison of the Fuel Needed to Transport Plastic Recyclables Verses Aluminum Recyclables from Yellowstone National Park

Research has provided no definitive answers on whether PET plastic bottles or aluminum cans are a more environmentally sustainable choice as soda containers. This paper researches the fuel used in recycling each of these materials from Yellowstone National Park to processing locations. The data is used to determine which of these alternatives use less fuel in this process. It was found that plastics use more fuel when transported from Yellowstone National Park to the processing center. Aluminum uses less fuel per ton to transport from Yellowstone to the processing center. The conclusions from this research may have implications on which material would be advised to use in selling soda in Yellowstone National Park.
