Japan urged to shift packaging policy focus from disposal to circular design

JAPAN – Japan must strengthen its packaging circularity policies by moving beyond disposal-focused waste management and placing greater emphasis on waste prevention, product longevity, and design for reuse and recycling, according to Shunichi Honda, programme officer at the UN Environment Programme’s International Environmental Technology Centre (IETC).

Honda said that while Japan is widely regarded as having one of the world’s most technically advanced waste management systems, its policy framework remains heavily weighted toward end-of-pipe solutions rather than upstream interventions that reduce waste generation in the first place.

“In my view, advancing circular economy practices in Japan requires moving beyond a focus on end-of-pipe solutions and strengthening incentives across the entire value chain,” Honda said.

He argued that packaging circularity must be addressed at the design stage, with policies that encourage reuse-ready formats, recyclable materials, and longer product lifespans.

At the event, Honda highlighted the growing role of artificial intelligence in optimizing waste collection, sorting, and monitoring systems.

He noted that AI-driven technologies, combined with stronger ESG-aligned investment frameworks, could help scale safer and more efficient national recycling systems.

However, he stressed that technology alone will not solve waste pollution without supportive legislation and coherent policy reforms.

Japan has invested heavily in intermediate waste treatment infrastructure, particularly thermal treatment with energy recovery, which plays a significant role in handling packaging waste.

According to Honda, this approach has successfully reduced landfill dependency and supported stable waste processing.

“Japan’s waste management system is often seen as technically advanced and operationally reliable,” he said, pointing to high collection coverage, low levels of illegal dumping, and strong household-level waste separation practices.

Despite these strengths, Honda identified persistent structural challenges. Material circulation rates remain modest relative to national and international policy ambitions, and incineration continues to dominate over upstream waste prevention and material reuse.

Demographic pressures, including an ageing population and a shrinking workforce, are also placing increasing strain on municipal waste services.

In addition, recent global disruptions have exposed vulnerabilities in recycling markets, underlining the need for more resilient and adaptable systems.

Honda emphasized that circular economy practices will only scale if they make economic sense for both businesses and local governments.

Key enablers, he said, include clearer market incentives for secondary materials, stronger alignment between environmental and industrial policy, and targeted support for small and medium-sized enterprises, which often drive practical innovation but face higher financial and operational risks.

Governance and coordination are equally critical. Honda noted that effective circular transitions depend on collaboration across ministries, municipalities, industry, and consumers, supported by transparent data, shared responsibility, and long-term policy consistency.

“Ultimately, the circular economy is not just a technical agenda but a societal choice,” Honda concluded.

“Policies work best when they reinforce a shared understanding that resource circulation is essential to long-term economic resilience and competitiveness.”
