Toward Circular Creative Society
driven by mutual respects

Starting from Kamakura City and Keio University

City of Kamakura, one of Japan's SDGs Future Cities, has been striving to realize Zero Waste Kamakura vision through waste reduction and recycling. This project brings about local consumption of local plastic waste by employing Keio University's technological expertise on digital platforms, IoT and 3D printing. It also engages in co-creation of fulfillment and happiness by supporing civic participation into each aspect of material ciculation. Collection activities, information on material, design ideas and other data will be accumulated and organic ties among them facilitated by digital platform will leads the process of not only material circulation but also development of new businesses. This package of technologies and social system "Kamakura-Keio Model of local consumption of local plastic waste" will be deployed widely in Japan and beyond.

Social Context

1

Resource depletion

According to population growth, it is said that most of resources on the earth would be use up until 2050.

2

Aging and retirement of incineration facilities

Thermal recycling (an energy recovery) has been recognized as effective in Japan, but aging incineration facilities are now close to their life limits.

3

Amendment to the Basel Convention

Import and export of plastic waste not suited for recycling is now regulated, and domestic processing became necessary.

Our Vision

Creation of creative circular economy
through realization of cities
with local consumption of local plastic waste

Creation of creative circular economy
through realization of cities
with local consumption of local plastic waste

We will produce what a city needs in the future by converting what has been considered a trash in the past into a resource and generating value with reprocessing.

Our view on "values"

Conventional Zero Waste

City of Kamakura, one of Japan's SDGs Future Cities, has been involving her citizens, industries, and municipal government to realize "Zero Waste at Kamakura" vision through a wide variety of activities

Updated Zero Waste

We strive to reduce the amount of incinerated trash while pursuing the "local consumption of local waste," generating values from recycled materials and creating new products and services. We thus create a Creative Circular Economy and make it a vibrant economy.

Our Targets

1

Smart monitoring of the local plastic circulation in a city and development of the digital twin

2

Cirular infrastructure based on recycled materials and realization of a walkable city

3

Market development for products with environemental friendliness certifications

Packaging and deployment

Target to be reached circa 2030

The three-in-one "Kamakura-Keio Model" package of a digital platform, municipal policies, and business models will be developed and deployed for wider adaption.
