Bob Kaster was an engineering whiz as a youngster and started a computer building business while in college. He later found his passion working with an environmental company in Phoenix. His work consisted of recycling old technology products and ways to help reduce waste in disposal sites across the United States. On his spare time he enjoyed photography and produced Maps of the World for educational purposes. His footprint remains as a passionate person who cared for the environment both as a waste management representative and as a builder of World Maps for education.
