As the world marks World Water Day on March 22, Kosmos Innovation Center (KIC) is proud to highlight the remarkable work of Velho Carbons Ltd., a KIC-supported business that is redefining sustainable water purification for agriculture in Ghana. Through KIC’s partnership with the Mastercard Foundation, many young entrepreneurs like Velho Carbon receive training and capacity building in entrepreneurship within the agricultural and agri-adjacent sectors.
Innovative Water Purification for Sustainable Farming
Water quality plays a crucial role in sustainable agriculture, impacting soil health, crop productivity, and overall food security. Many farmers in Ghana face the challenge of accessing clean water for irrigation due to industrial runoff, chemical residues, and microbial contamination.
These pollutants degrade soil fertility, reduce yields, and threaten long-term agricultural sustainability.
Velho Carbons Ltd. is addressing this pressing issue through innovative and eco-friendly filtration solutions. By repurposing organic waste—primarily coconut husks—into high-quality activated carbon, the company provides natural and cost-effective filtration systems that remove impurities, contaminants, and toxins from water sources. This initiative is not only improving irrigation water quality but also promoting healthier crops and sustainable farming practices.
A Circular Economy Approach
Beyond filtration, Velho Carbons Ltd. embraces the principles of the circular economy, ensuring that agricultural waste is transformed into valuable resources. By converting coconut husks into activated carbon, the company is reducing waste while contributing to environmental conservation and climate resilience. Their technology mitigates the impact of waterborne pollutants on ecosystems, reinforcing the urgent need for sustainable water management in agriculture.

Empowering Farmers and Communities
“At Velho Carbons Ltd., the mission is clear: to empower farmers, agribusinesses, and communities with access to clean water for irrigation, ensuring food security and environmental preservation.” Dr. Erastus Mak-Mensah, Co-Founder of Velho Carbons Ltd.
