Zenco Group produces renewable energy, biochemicals, and synthetic fuels from seaweed cultivated in polluted ocean waters. The company harvests seaweed that absorbs agricultural run-off and wastewater nutrients, pelletises it into stable feedstock, and processes it through anaerobic digestion to create Zenethane biomethane, Zemicals biochemicals, and Zenthynol synthetic fuel.

Problem
Agricultural run-off and wastewater dumping flood oceans with excess nutrients, creating over 500 recorded dead zones worldwide where marine life cannot survive. These polluted waters degrade ecosystems and represent a wasted opportunity to recover nutrients as valuable resources.
Solution
Zenco Group cultivates seaweed at scale in damaged ocean waters, where it naturally absorbs excess nitrogen, phosphorus, and heavy metals as it grows. The harvested seaweed is dried, blended with complementary inputs, and compressed into standardised pellets that serve as stable, shippable feedstock for anaerobic digestion. At their bioenergy hubs, these pellets are processed through anaerobic digestion to produce three products: Zenethane (biomethane for renewable energy), Zemicals (biochemicals), and Zenthynol (synthetic fuel via Fischer-Tropsch synthesis). This circular process brings ocean waste back to land as products that replace fossil-based alternatives, simultaneously cleaning marine environments.
Target Audience
Primary customers are bioenergy producers, fuel distributors, chemical manufacturers, and industrial energy consumers seeking renewable drop-in fuels and biochemicals with verified environmental remediation benefits.
