By simply storing vegetables, fish, and meat in a bag, you can slow down food oxidation and maintain freshness! After disposal, it naturally returns to the soil with biodegradable features.

"MARCHE" is a storage bag that can keep the deliciousness of items like bread and rice simply by placing them in the packaging. Vegetables sold at room temperature can be stored for a long time at room temperature. Fruits can also be stored for a long time at room temperature, not only delaying deterioration but also promoting ripening. Even perishable foods like sashimi, cut vegetables, and ground meat can maintain their freshness for a longer time when stored in this product. 【Points】 ■ Reusable: Economical and can be used repeatedly. ■ Care: If it gets dirty, wipe it clean as much as possible. (Washing with water may reduce its effectiveness due to chlorine.) ■ Replacement sign: When the bag loses its transparency or becomes sticky, it's time for a replacement. It cannot be used in the freezer. ■ Expiration date: Approximately 12 months after purchase. (Due to its biodegradable function, the bag will gradually deteriorate.) *For more details, please download the PDF or feel free to contact us.

Excellent moisturizing and excellent stretch! It decomposes into carbon dioxide and water through a two-step process.

"Gakubuchi-kun" is a product that uses a revolutionary additive that leads difficult-to-decompose plastics, which are considered hard to biodegrade, to microbial decomposition. The name comes from the fact that mulch film has both covered and exposed parts; the exposed parts are promoted to biodegrade by sunlight, oxygen, and heat, while the parts covered by soil remain like a "gakubuchi," hence the name. Exposure to direct sunlight accelerates the decomposition rate. The stretching period is approximately 5 to 6 months. 【Features】 ■ Uses a revolutionary additive that leads difficult-to-decompose plastics to microbial decomposition ■ Extremely excellent moisture retention, allowing for stretching similar to regular mulch ■ Decomposes into carbon dioxide and water through a two-step process ■ Exposure to direct sunlight accelerates the decomposition rate *For more details, please refer to the PDF materials or feel free to contact us.

[Speaker] Naoki Toda, Chief Economist, Management Strategy Research Office, Tokyo Electric Power Company Holdings, Inc. [Key Lecture Content] Since the 1990s, the global advancement of power system reforms has aimed for efficiency and optimization in both the operation and investment of facilities through active market competition. However, with the progress of DX/GX, the anticipated scenarios for electricity demand have led to the emergence of underinvestment issues worldwide. The IEA's report "Electricity Market Design," published last year, provides a comprehensive review of the reform situations in various countries and indicates that the underinvestment problem is a common issue across the globe. In this lecture, I will explain the current state of the underinvestment issue and potential responses from a business system perspective, referencing the IEA report and others. [Lecture Items] 1. Background of power system reforms and the underinvestment issue 2. About IEA "Electricity Market Design" 3. Reflecting on the thoughts of Akihiro Sawa on the 10th anniversary of his passing 4. Possible solutions to the Tenor Gap issue 5. Outlook for Japan's power system 6. Q&A / Business card exchange

[Instructor] Shinichiro Takiguchi, Senior Specialist, Innovation Strategy Center, Japan Research Institute, Inc. [Key Lecture Content] With the increase in renewable energy, the introduction of energy storage systems has progressed in two forms: renewable energy co-located systems to adjust power generation fluctuations, and demand co-located systems to secure electricity during grid outages. However, the landscape is changing significantly. The "Supply and Demand Adjustment Market" has been established by OCTTO (Organization for Cross-regional Coordination of Transmission Operators), and particularly due to the continued high pricing agreements in the short-term response market (primary adjustment power responding within 10 seconds), there have been numerous cases where battery storage profits are secured through market transactions. In the grid energy storage business, two capabilities are required: "trading power" and "financial power." This lecture will explain the business structure and key points of profitability. Additionally, based on this business structure, we will classify the companies entering the grid energy storage business and organize the market structure of this sector. As this business is influenced by regulatory trends, we will also discuss regulatory outlooks. Finally, we will talk about future prospects.

[Lecturer] Professor Yoshiharu Nishimura, Senior Researcher, Kansai Electric Power Co., Inc. Graduate School of Engineering, Osaka University, Business Engineering Program [Key Lecture Content] The examination of the next-generation power infrastructure conducted in 2025 has entered the implementation phase, including amendments to the Electricity Business Act, towards a new power policy standard (a sustainable framework by responsible players) in 2026. This lecture will outline the content and related policy adjustments for businesses involving renewable energy and storage batteries, and consider the correct business concepts, necessary timelines, and how to create business models moving forward. [Lecture Items] 1. What is the 2026 Next-Generation Power Infrastructure Reconstruction? 2. Renewable Energy and Decarbonization Policies and Issues with Chinese Products 3. The Latest Status of Storage Batteries and the Timeline and Vision for DER Business 4. Q&A / Business Card Exchange
