Introduction
In recent years, as environmental problems and resource depletion have become more serious, there is a growing need to rethink the very systems that support our daily lives. Concepts such as the “circular economy” and “sustainable supply chains” have been attracting attention, and each of us has the potential to contribute to the future of our planet. This article describes specific recycling, supply chain, and environmental protection initiatives and considers how we can get involved.
What is the Circular Economy?
The Circular Economy refers to an economic model in which resources are used repeatedly, shifting away from the traditional linear “make, use, throw away” economic model. This system provides significant environmental and economic benefits through the reduction of waste and the efficient use of resources.
Specific Examples and Benefits of Circular Economy
For example, there is an initiative to recycle plastic bottles to produce new plastic bottles and clothes. This reduces waste disposal costs and at the same time reduces the mining of new resources, thereby reducing environmental impact. It also provides an opportunity for companies to create new business opportunities by expanding the market for recycled products.
Initiatives around the world
In the EU, schemes such as the “Battery Passport” and the “Digital Product Passport” have been introduced, which aim to make the entire process transparent, from product manufacture to recycling. For example, the traceability of recyclable battery materials has been improved, making it easier for both consumers and companies to make environmentally conscious choices [1][2].
Current Status and Challenges of Recycling
Recycling is an important means of environmental protection, but it also poses various challenges.
How to Increase Resource Reuse Rates
In Japan, the recycling rate for PET bottles is high at about 85%, while in the U.S. the rate is only about 30%. Another issue in Japan is the lack of uniform sorting methods and collection systems in each region. Introducing a unified nationwide recycling method and ensuring that consumers sort their waste accurately will lead to further efficiency gains [3].
Issues in the Supply Chain
Many of the materials for lithium-ion batteries are dependent on certain countries. Therefore, it is important to enhance recycling technologies and expand the supply of raw materials through recycling. In particular, as demand for critical resources such as lithium and cobalt increases with the spread of electric vehicles, international cooperation is required to ensure supply chain stability [1] [2].
Building a Sustainable Supply Chain
A supply chain refers to the series of steps involved from raw materials being processed into products to their final delivery to consumers. The goal of a “sustainable supply chain” is to build this in an environmentally friendly manner.
Elements of a sustainable supply chain
Risk Management: Plan for risks such as disasters and supply disruptions.
Data transparency: Visualize the manufacturing process and recyclability of products.
Stakeholder Collaboration: Bringing companies, consumers, and governments together.
Specific examples
In parts of Europe, frameworks have been introduced to assess environmental impacts throughout the supply chain. For example, major companies are working to require their suppliers to use renewable energy and increase recycling rates [4].
The Role of Technology and Policy
The use of technology and the development of policies are essential to achieving a sustainable society.
Use of Digital Technology
In Sweden, recyclable materials are shared among companies through a waste management platform to achieve efficient resource use. In addition, some local governments in Japan are using AI to automate waste sorting and improve recycling rates. Such technological innovations contribute to both reducing environmental impact and costs [2] [4].
Policy Promotion
In Japan, the “Act on Promotion of Recycling of Plastic Resources” has been enforced, and a system has been established to facilitate participation in recycling by both companies and consumers. Meanwhile, in the EU, the “EU Battery Regulation” mandates battery recycling rates and the use of recycled materials, promoting the efficient use of resources [1][2].
What Consumers Can Do
Each of us can take a step toward a sustainable future by changing our awareness in our daily lives.
A list of actions that can be easily started
・Ensure garbage separation and correct collection of recyclable resources.
・Choose recycled and environmentally friendly products.
・Avoid disposable products and use reusable items.
・Participate in local environmental events and workshops to spread knowledge.
・Reduce overall energy consumption by reducing wasteful use of electricity and water.
Conclusion
Initiatives such as recycling, the circular economy, and sustainable supply chains are key to protecting our future global environment. Success in these efforts depends not only on the actions of governments and corporations, but also on our individual actions. Small actions add up to a better society. Let us work together to achieve a sustainable future.
