Root-Zone Water Retention for Drought and High-Temperature Stress Countermeasures | On-Site Demonstration Solutions for Biodegradable Superabsorbent Polymers (EF Polymer)

For regions where seedlings must be raised with limited irrigation, such as during prolonged dry seasons or in sandy soils, we propose a combination of the biodegradable superabsorbent polymer “EF Polymer” and a root-zone water retention process based on local verification. Starting with demonstrations in Nigeria, we are driving global expansion into the agriculture, afforestation, and greening sectors.

The Water Shortage Challenge of “Prolonged Dry Seasons × Sandy Soil” Occurring in Nigeria

As dry seasons lengthen and rainfall becomes unpredictable, limited irrigation is absorbed by sandy soil before reaching the root zone, making survival rates and growth unstable. Securing and efficiently utilizing agricultural water has become urgent. Even if the irrigation volume is increased, water escapes in sandy soil, leading only to soaring costs.
● Scenarios where this becomes apparent: Overseas farmland and afforestation sites. Backed by the prolongation of dry seasons due to climate change.
● Main impacts: Decrease in seedling survival rates, uneven growth, and deterioration of crop yields and afforestation success rates.

Why Increasing Irrigation Does Not Solve the Problem: Dual Factors of Natural Elements and Soil Physical Properties

In addition to natural factors (prolonged dry seasons and unpredictable rainfall), the water retention capability of sandy soil is low, making it impossible to retain water in the root zone.
● Grounds for identification: Observations at local fields and control test data.

Countermeasures Attempted So Far and Their Limits

Increasing irrigation volume (limited by water costs and labor) and water-retaining mulch materials (washed away by wind and rain).
Based on these limitations, we adopted the following approach as a more fundamental solution.

Solution Approach: EF Polymer × Local Control Tests × Packaging of the Application Process

Proposing a new material (biodegradable superabsorbent polymer) combined with collaboration between overseas bases and partner trading companies, and designing a root-zone water retention process based on local verification (control tests).

Thermal Barrier Paint Solution to Reduce Factory Electricity Bills in Thailand | Arranging Local Application Partners | Collaboration Across 3 Bases: China, Thailand, and Vietnam

In the Thai manufacturing industry, continuous increases in electricity rates and prolonged dry seasons have caused factory electricity bills—primarily for air conditioning—to squeeze profits. Focusing on the application of thermal barrier paint to roofs, we provide one-stop support ranging from electricity bill reduction simulations to the arrangement of local application partners and localized currency quoting. As a realistic solution to lower running costs with low investment and short construction periods, this has already been adopted by multiple Japanese factories. Soaring Electricity Bills in Thailand: What Was Happening Inside the Factories? Electricity rates in Thailand have undergone repeated increases due to fuel cost adjustments, making the pressure on production costs a chronic issue. Especially in factories with large roof areas, coupled with the prolonged high temperatures of the dry season, air conditioning systems run at full capacity constantly, inflating annual electricity bills to a level that demands executive-level management decisions. On the other hand, upgrading power reception and transformation equipment or installing solar power presents high hurdles regarding initial investment, construction periods, and the shutdown of existing facilities, leaving many facilities unable to take action."We want to lower our electricity bills. We also want to deliver results in the context of SDGs and CO2 reduction. However, we cannot commit to capital expenditure on equipment."——We hear these exact concerns from numerous Japanese factories operating local subsidiaries. Why Aren't Electricity Bills Dropping? Radiant Heat from the Roof Keeps Air Conditioning Running Constantly The root cause revealed through on-site inspections and roof surface temperature measurements is a structural issue: the roof and exterior walls lack heat-insulating performance, allowing radiant heat to flow directly into the interior. In some cases, the roof surface temperature exceeds 70°C during the day, and this heat warms up the ceiling space and indoor air, meaning the air conditioning cannot keep up no matter how much it cools.Furthermore, factory buildings in Southeast Asia often have outdated insulation specifications, so upgrading air conditioning units alone rarely provides a fundamental solution—this is the main reason why many hesitate when considering upgrading existing facilities.The basis for identifying this cause comes from cross-referencing the following two points:・Reviewing current electricity bill data provided by the customer・Measuring roof surface temperatures and checking roofing materials during on-site inspectionsBy matching these two datasets, we can conclude with near certainty that "heat inflow from the roof is the dominant factor." Countermeasures Attempted Thus Far and Their Limitations Countermeasures already attempted by many factories share the following common limitations:・ Adjusting HVAC operating hours: The effect is limited, and the system still faces high loads during production hours.・ Considering heat-insulating film application on the roof: Frequently abandoned due to hurdles in cost and construction periods.・ Considering retrofitting insulation materials to existing equipment: Requires halting existing equipment during construction, resulting in too great an impact on production.Given these limitations, thermal barrier paint emerges as the realistic solution—a move that "reduces heat inflow from the roof without stopping existing operations." Solution Approach: Thermal Barrier Paint × Electricity Bill Simulation × Local Application Partners By focusing on top-coating existing roofs with thermal barrier paint and providing the following three components as a complete package, we lower the hurdle for customers to make the decision to "give it a try." STEP. 01 Sourcing Alternative Materials and Replacements We perform a matrix comparison of both Japanese and local manufacturer products based on required performance, roof material compatibility, and cost to select the optimal thermal barrier paint grade. Focusing primarily on products with a proven track record in Thailand, we also obtain evaluation data from cooperating manufacturers as needed. STEP. 02 Presentation of Electricity Bill Reduction Simulations Based on current electricity bill data, HVAC operating hours, roof area, and insulation specifications, we will estimate the post-application electricity bill reduction effects and the payback period. Visualizing the "numbers" necessary for management decisions significantly accelerates the internal approval speed. STEP. 03 Selection of Local Construction Partners and Quotations in Local Currency Leveraging our Thai base as a starting point, we select reliable local application partners and optimize pricing and lead times via local currency quoting. We also propose process designs that minimize the impact on your production, including night/weekend application and split-phase application block by block. FUJICHEMI TRADING's Support Framework: A Powerful Triad of Japan HQ, Thai Base, and Cooperating Manufacturers This solution is realized through a clear division of roles among three parties: Japan HQ (Sales/Technical), our Thai base, and cooperating manufacturers.・ HQ (Sales/Technical): Selects coatings / Prepares electricity bill reduction simulations / Supports decision-making for adopting companies・ Thai Base (Local Subsidiary): Conducts on-site inspections, selects application partners, and provides local currency quoting/contracting / Manages application and construction / Provides after-sales support・ Cooperating Manufacturers: Supplies thermal barrier paint / Assists in grade selection / Provides evaluation data● Supply Framework: Local inventory support and small-lot application are available. This enables a small-start introduction where you can first test the effects on a single building before rolling it out across subsequent buildings. Results of Adoption: Simultaneously Achieving Running Cost Reductions and Workplace Environment Improvements We have received the following qualitative and quantitative result reports from adopting companies:・ Reduction in factory running costs (electricity bills): Achieved a reduction (▲) in electricity bills based on actual customer data.・ Lower indoor and roof surface temperatures: Stabilized summer production efficiency due to improvements in perceived temperature.・ Visualization of the payback period: Increased the precision of management decisions, accelerating subsequent rollout evaluations.・ Rollout track record: Cases exist where introduction to a single building led to expansion across additional buildings and sister factories.● Introduction Lead Time: Rapid turnaround is possible from the initial consultation through estimation to test painting. Anticipated Ripple Effects and Rollouts: 3 Returns Beyond Just Electricity Bill Reductions The effects of adopting thermal barrier paint extend far beyond electricity bill reductions. Please utilize these cascading ripple effects triggered by "heat mitigation" as supporting material for your internal proposals.1. Workplace Environment Improvement → Lower Turnover Rates and Higher ProductivityBy mitigating the extreme heat directly beneath the roof, the workload on workers during hot seasons is reduced. As securing and retaining operators is a pressing management issue in Thai manufacturing sites, improving the workplace environment directly links to lower turnover rates and enhanced productivity.2. Contribution to SDGs and CO2 Reduction ReportsElectricity bill reductions can be directly quantified as carbon emission reductions, leading to immediate score improvements in CSR and supplier evaluations. In an era where global headquarters' procurement standards closely scrutinize "suppliers' CO2 reduction track records," leaving behind quantitative data holds great value.3. Extending the Service Life of Rooftop EquipmentLowering the roof surface temperature reduces thermal stress on outdoor HVAC units and solar panel peripheral equipment, which can be expected to extend equipment life. This creates a double benefit: electricity bill savings combined with delaying future equipment replacement costs.Furthermore, for customers who establish a proven track record of introduction in Thailand, we can also support the horizontal rollout of identical proposals to your factory bases in Vietnam and China. Differences from Competitors: Why Choose FUJICHEMI TRADING? Compared to competitors that only sell coating products (paint manufacturers' direct sales and local chemical trading companies), our unique strength lies in our ability to provide a seamless, end-to-end service encompassing "electricity bill simulations + local application partner arrangements + local currency settlement." Our network, which bridges Japanese-level quality and localized cost structures, is the reason we continue to be chosen.・Difference from Manufacturers' Direct SalesThey do not provide simulations or arrange application partners, requiring customers to handle these arrangements individually.・Difference from Local Paint DistributorsWe offer selection based on Japanese quality standards, along with technical support in Japanese and proposal materials tailored for executive-level management.

Reducing Factory Electricity Costs & Heat Countermeasures | Developing Custom-Processed Heat-Insulating & UV-Cut Sheets (Japan-ASEAN Collaboration)

In response to the triple demands of soaring electricity costs, SDGs compliance, and working environment improvement, our company has designed an original processed sheet with heat-insulating and UV-cutting functions. By coating non-woven fabrics or films with specialized paint and providing them in a format that lowers installation barriers, we have expanded our target audience to include customers with rental properties and those looking to protect existing facilities. Triple Demands: Soaring Factory Electricity Costs, SDGs Requirements, and Working Environment Improvement There is a strong desire to simultaneously reduce factory electricity costs and implement heat countermeasures. Many customers requested a sheet format that is easy to install, rather than just the paint itself.A format was needed that could be implemented even by customers for whom applying paint is difficult (rental properties, protection of existing facilities).● Scenarios of Emergence: The triple demands of rising electricity costs, SDGs compliance, and working environment improvement are becoming prominent.● Main Impacts: Deterioration of factory running costs, decline in winter/summer working efficiency, and unfulfilled CSR requirements. Why Existing Solutions Fall Short: Paint Application Barriers and the Limits of Conventional Insulation Materials Conventional heat-insulating countermeasures were based on the premise of paint application, creating a high barrier for installation work.● Specific Basis: Sample evaluations and on-site interviews. Solutions Tried So Far and Their Limitations Installing conventional insulation materials (unfeasible due to weight and poor workability), updating air conditioning units only (requires large investment).Based on these limitations, we adopted the following approach as a more fundamental solution. Solution Approach: Optimizing the Combination of Paint, Film, and Non-Woven Fabric × Developing Custom-Processed Products We developed our own custom-processed product by coating non-woven fabrics and films with specialized paint, lowering implementation barriers through sample provision and small-lot sales. STEP. 01 Material Combination Optimization Reviewing the configuration of paint × film × non-woven fabric STEP. 02 Custom-Processed Product Development Transforming into an easy-to-install format through coating and slitting processes STEP. 03 Utilization of Overseas Bases Utilization and cross-regional expansion of products supplied overseas (sharing evaluation data) STEP. 04 Cost Simulation Visualizing cost structures to support informed implementation decisions Fuji Chemi Trading's Service Network: Head Office (Sales & Technology) × ASEAN Bases This solution is achieved through a clear division of roles across multiple bases.・Head Office / Domestic Sales: Customer window and cost simulation・Technology & Development: Coating recipe development for paints, and preparation of evaluation data・Thailand and Vietnam Bases: Sharing evaluation track records at ASEAN factories● Supply System: Sample provision, small-lot sales, and in-house custom processing support. Results of Implementation Achieved a reduction in factory running costs (electricity bills). Successfully developed into a cross-regional proprietary product that is also effective for acquiring new customers.● KPI Candidates: Electricity cost reduction (on an estimated basis) / Room temperature drop in implemented factories / Record of cross-regional expansion to additional buildings and group factories.● Implementation Lead Time: Fast-track response from sample evaluation to small-lot supply. Anticipated Ripple Effects and Cross-Regional Expansion The implementation effects of this solution go beyond solving the primary challenge. Please also utilize it as compelling material for internal and management-level proposals.・Continuous tailwinds from soaring electricity costs and environmental regulations will drive mid-to-long-term growth in lead generation.・Expansion to applications beyond roofs and outer walls (such as windows, skylights, and partitions).・Proposals addressing the same theme for ASEAN factories can be rolled out, driven from Japan-based sites.・Utilized internally by customers as evidence for SDGs/CO2 reduction reports, creating an internal word-of-mouth diffusion effect.
