As Africa’s innovation ecosystem gathers momentum, the AfricArena Nairobi Summit (September 9-10, 2025) emerges as a critical platform for forging transformative partnerships. Among the standout participants are four Korean ClimateTech startups - GreenerLab, IOMTEK, tAB, and BrownSkin - each bringing field-tested solutions to address Africa’s most urgent challenges: ecosystem degradation, food insecurity, water contamination, and agricultural waste. Presented at recent Korea-Africa forums, their technologies promise to create jobs, reduce environmental impact, and build resilient local economies, particularly in Kenya. Here’s a deep dive into their innovations and how they’re poised to collaborate at AfricArena.

GreenerLab: Digitizing Ecosystem Stewardship with AI

Revolutionizing Tree Care

GreenerLab, a Seoul-based software innovator, is redefining environmental management with its 3A (Tree A) Platform, dubbed an “Electronic Medical Record (EMR) for Trees.” This AI-driven system empowers communities, governments, and NGOs to monitor and maintain forests with precision, tackling deforestation and boosting carbon sequestration.

How It Works

• Smart Diagnosis: Users - whether Kenyan county officials or rural foresters - select a tree species (e.g., African blackwood), input data like soil pH, moisture, drainage, and light conditions, and upload photos capturing up to 80 angles of branches, roots, and trunks.

• AI Analysis: Embedded AI cross-references inputs with global agricultural databases, diagnosing issues like nutrient deficiencies or pest damage. It generates prescriptive actions, detailed reports, and “medical certificates” compliant with standards from the Korean Ministry of Forest and the International Society of Agriculture.

• Offline Accessibility: Designed for remote African regions, the platform works on smartphones or tablets with minimal internet, integrating with maps for “Digital Tree” projects that display tree details (scientific names, ages, care histories).

• Data Tracking: Monitors forest health metrics (pH, moisture, temperature) and trends (growth, carbon sequestration), enabling month-over-month reporting.

Impact Highlights

• Cost Efficiency: Reduces tree care costs by up to 60%, addressing expenses from pruning, watering, and monitoring.

• Ecosystem Resilience: Supports Kenya’s goal of planting 15 billion trees by 2032 with higher survival rates through targeted interventions.

• Job Creation: Trains a workforce of “tree doctors,” fostering employment in rural and urban areas.

• Global Reach: Deployed in Korea, Japan, the EU, and a Kenyan decarbonization project, enhancing urban green spaces and combating desertification.

AfricArena Opportunity

GreenerLab seeks partnerships with African governments, municipalities, and NGOs to deploy pilots in Kenya. At AfricArena, they could train communities, track carbon credits, and scale reforestation, aligning with Kenya’s environmental priorities.

IOMTEK: Transforming Agriculture with Climate-Smart Greenhouses

Farming Without Limits

IOMTEK, a Korean materials science leader, is tackling food insecurity in hot climates with a revolutionary greenhouse coating that eliminates energy-intensive cooling and chemical pesticides, ensuring abundant harvests.

How It Works

• UV Management: The film blocks ultraviolet light to disorient pests, creating a natural barrier that eliminates pesticide use while keeping farmers safe.

• Heat Regulation: Releases excess heat externally, maintaining cooler greenhouse interiors than competitors, as verified by third-party testing.

• Photosynthesis Boost: Filters light to optimize photosynthesis, resulting in healthier, more robust crops.

• Sustainable Design: Requires no electricity, water, or chemicals, making it cost-effective and eco-friendly.

Impact Highlights

• Exceptional Yields: Trials in Korea (4 years), Malaysia, and Vietnam show a 700% increase in crop yields, with larger, healthier tomatoes, grapes, and cabbage.

• Pest-Free Farming: Achieves 0% pest damage without pesticides, reducing health risks and costs.

• Climate Resilience: Extends productive hours in Kenyan greenhouses, where heat limits work to early mornings.

• Scalable Pilots: Trials planned for Kenya and South Africa, with full readiness by December 2025.

AfricArena Opportunity

IOMTEK seeks Kenyan manufacturers, distributors, and pilot farms to localize production. AfricArena’s agrotech investors could establish regional hubs, enhancing food security for smallholder farmers.

tAB: Ensuring Clean Water for Vulnerable Communities

Water Safety for All

tAB, a Korean water technology pioneer, addresses global water contamination with two solutions: a UV-based sterilization system and a gravity-powered SK Type filter, designed for immunocompromised groups and low-income communities.

How It Works

• UV Sterilization System: Uses UV light to eliminate bacteria from surfaces, food, soil, and water. Certified by USDA and European standards, it serves immunocompromised patients (e.g., leukemia, chemotherapy), baby product manufacturers, military applications (e.g., vehicle cleaning), and drinking water treatment.

• SK Type Filter: An electricity-free filter attaches to taps or jerrycans, producing 1-2 liters of clean water per hour. Made from locally sourced materials (metal, specialized paper), it removes contaminants like E. coli and supports community production.

• Sustainable Model: The filter’s simplicity reduces reliance on imports or boiling, making it ideal for developing regions.

Impact Highlights

• Health Transformation: In a pilot, the filter reduced childhood diarrheal cases by 94% within one month, addressing waterborne diseases.

• Scalable Production: Produced 2,500 units last year; distributed 100 units free in February 2025.

• Global Reach: The sterilization system is used in the US and Europe, while the filter targets Africa’s water crisis, particularly in Kenya.

AfricArena Opportunity

tAB seeks CSR programs, UN agencies, and local distributors for free deployments in Kenya. AfricArena’s NGO network could advance SDG 6 (Clean Water and Sanitation) through community partnerships.

BrownSkin: Upcycling Waste into Sustainable Fashion

From Waste to Wardrobe

BrownSkin, a Korean advanced materials company, transforms Kenya’s 5.2 million tons of annual agricultural waste (valued at ~72 billion KSh) into eco-friendly leather, creating a circular economy in fashion and agriculture.

How It Works

• Three-Stage Process:

  1. Collection and Testing: Agricultural byproducts (e.g., fruit skins, coffee husks, cow shells) are gathered and analyzed.

  2. Drying and Thermal Processing: Materials are dried and processed for durability.

  3. Freeze-Drying and Binding: A natural binder (e.g., apple fiber) creates continuous leather rolls, 20% stronger than traditional leather.

• Key Features: Naturally antimicrobial and deodorizing (Swiss/Korean certified), produced in wide, long rolls unlike size-limited animal leather.

Impact Highlights

• Waste Reduction: Diverts significant portions of the 40% global agricultural biomass waste, reducing landfill reliance and eliminating 250 toxic chemicals used in tanning.

• Versatile Applications: Supplies leather rolls, offers OEM/ODM services for goods like bags (30 years of design expertise), and develops cosmetics from waste.

• Global Partnerships: Collaborates with European fashion brands, Asian food and beverage companies (e.g., converting cow shells), and major retailers.
