１. What is recycling business?

Recycling business＝Wastemanagement(public sector)

Fuels production
business＋(private sector)

Recycling business is a compound industry of Waste management andFuels production business . Waste management is a kind of public
service of sanitization, fuels production is a private business to returnthe recycled resources to arterial industry. In Japan, with the more than
20 years system development and socioeconomic evolution, currently
the proportion of private business becomes the majority rather thanpublic service, that generally it could be said the private sector has
become the leading role.

32. Requisite for the business as a social infrastructure○In the field of recycling business,
only having the patents required
technology cannot gain the market.
○With the market changes (e.g. ＰＥＴ
bottle popularization), the needs oftechniques will appear where social
system and policies are adjustable.
○In the market, recycling businesswould not be sustainable if it only
stands on the subsidies.
○Oppositely, the business will not
function without economically feasible
technical support, even though thepolicy system is developed.
⇒Recycling business can function as asocial infrastructure throughpackaging the technologies andsocial system.

MOU of promoting a low carbon hydrogen city between Kawasaki
city government and Showa Denko
On 28th July in 2015, MOU were concluded.
Kawasaki city government and Showa Denko aims to developing a low carbon hydrogensociety with low environmental burden by utilizing hydrogen production system from wasteplastics.

Win-win relationship＜Objectives＞
1)Utilization of existed infrastructure,knowledge and experience2) Substantiates experiment and trial tocommercialization of low carbonhydrogen from waste plastic, resulting incontributing to establishment of a lowcarbon society

Collaboration＜Objectives＞
Based on “Kawasaki Hydrogen
Project”, Kawasaki city
government has promoted“future eco city development”
