Solid Waste management & Recycling technologies in Kitakyushu
Historically, waste management systems focused on collection and disposal waste to protect
the health of city inhabitants and to improve the aesthetic appearance of territories. 19th century,
as cities grew and industrialized, more waste was produced and its composition changed dramatically.
Environmental protection and conservation started to receive increasing attention, and by the 20th
century waste was increasingly viewed also as a resource to recover materials and energy.
In the more economically developed countries, waste management gradually evolved from a focus
on disposal to a focus on prevention, recycling, and recovery.
Now, Japan is a global leader in the development and application of environmental policy in the
waste sector and Kitakyushu-city is the advanced city of solid waste management in Japan.
