Light industry are industries that usually are less capital-intensive than heavy industry and are more consumer-oriented than business-oriented, as they typically produce smaller consumer goods. Most light industry products are produced for end users rather than as intermediates for use by other industries. Light industry facilities typically have less environmental impact than those associated with heavy industry. For that reason zoning laws are more likely to permit light industry near residential areas.
Light industries require fewer raw materials, space and power. While light industry typically causes little pollution, particularly compared to heavy industry, some light industry can cause significant pollution or risk of contamination. For example, electronics manufacturing, itself often a light industry, can create potentially harmful levels of lead or chemical wastes in soil without proper handling of solder and waste products (such as cleaning and degreasing agents used in manufacture).
