purchased goods in order to reduce the number of disposed paper/plastic bags. Use water sparingly by installing water-efficient shower heads and faucets, and install energy-efficient appliances. Make sure that sinks and hoses are not dripping. Do not excessively water plants. Use transportation efficiently, and utilize mass transportation when possible. Recycling used motor oil is also a way to eliminate the disposal of a hazardous material. Eating locally produced foods reduces the amount of fuel required for the food's transportation. Additional examples of P2 include using energy efficient machinery, developing clean-burning fuel, reducing the amount of chemicals released into water sources, creating a production process that results in a reduced amount of waste, and utilizing water conservation techniques.
