Abstract:
Lubricant composition formulations comprising at least one biodegradable plastic, such as polyhydroxyalkanoate and/or polybutylene succinate, and at least one lubricant, such as a vegetable oil.

Claim (Index 1):
A method of reducing wheel and rail contact friction for railroads by controlled dosing of lubricant onto a wheel flange of a rail vehicle on a track, said method comprising:\n providing a biodegradable dosing composition comprising a biodegradable plastic component, a solid lubricant component, and a biodegradable lubricating oil component, wherein said biodegradable plastic component comprises a mixture of polyhydroxyalkanoate and polybutylene succinate, wherein the solid lubricant component comprises at least one of graphite, molybdenum disulfide, and a mixture of graphite and molybdenum disulfide, wherein said biodegradable plastic component comprises from about 30% to about 90% by weight of said biodegradable dosing composition, wherein said biodegradable lubricating oil component comprises from about 5% to about 50% by weight of said biodegradable dosing composition, and wherein said solid lubricant component comprises from about 5% to about 75% by weight said biodegradable dosing composition; forming said biodegradable dosing composition into a consumable dosing stick having a first end; utilizing an applicator to press the first end of the consumable dosing stick against the wheel flange of the rail vehicle; and abrading the consumable dosing stick against the wheel flange, wherein solid lubricant component and biodegradable lubricating oil abraded from the consumable dosing stick is applied to the wheel flange of the rail vehicle, and wherein the biodegradable plastic component abraded from the consumable dosing stick is dispersed along said track.
