Converting Waste Plastics into Fuel: Advancements in Technology

Efforts are underway to convert waste plastics into fuel through liquefaction. This technology can handle difficult-to-process plastics like PVC and ABS resin. It is expected to improve energy efficiency and reduce costs. A demonstration plant will be operated in Niigata City, with the goal of practical application by 1997. The project includes cooperation with local governments to conduct trial operations using household waste.

Progress Towards Practical Application of Biodegradable Plastics

The market for biodegradable plastics is expected to expand. Companies like Showa High Polymer and Japan Synthetic Chemical Industry are advancing composting demonstration projects using this material, aiming to protect landscapes and reduce environmental impact. In Kochi Prefecture, plans are underway to use biodegradable plastic pots for seedlings in roadside greening projects.

Efforts to Improve Water Quality Through Charcoal Utilization

In Togura Town, Nagano Prefecture, charcoal is being used to purify agricultural water contaminated with household wastewater. The charcoal is processed through simple purification devices, and is also used to clean agricultural water channels, leading to improved water quality and the return of Genji fireflies that had disappeared. Used charcoal is repurposed as a soil conditioner.

Development and Market Expansion of Biodegradable Plastics

The Economic Planning Agency's "2010 Technology Forecast" highlights biodegradable plastics as a promising new technology. Domestic demand is expected to reach 3 million tons annually, with commercialization efforts also progressing in Europe and the United States. The "Biodegradable Plastics Practical Application Study Committee," established under the leadership of the Ministry of International Trade and Industry, is accelerating research to bring this material to practical use.
