In the early 1970s, as a result of the rise in cumulative environmental issues, many local recycling programs were launched as a way to save natural resources. These efforts focused on post-consumer materials.
What explains this growth? A heightened political focus on energy issues then led to additional recycling efforts, given the substantial energy savings from recycling. However, cheap landfill costs meant that recycling’s growth was limited. But the greatest surge in governmental actions to expand recycling occurred in the late 1980s and early 1990s as a result of the perception of declining landfill space. Landfill siting battles helped spur added attention to recycling as a waste reduction method.irst, an increase in investment, especially in the 1990s, led to numerous world-class recycling mills being built. New deinked paper mills, all-recycled steel plants and new plastics recycling facilities were opened. Second, this investment was accompanied by the development of new recycling technologies, such as: –food-contact plastics reclamation –recycled sheet-steel production –improved paper deinking methods
