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. 19^th 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 20^th

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.
