Marubeni Corporation has announced an investment in AquaGreen Holding ApS, a Danish company specializing in technology that processes wet biomassBiomass is a complex biological organic or non-organic solid product derived from living or recently living organism and available naturally. Various types of wastes such as animal manure, waste paper, sludge and many industrial wastes are also treated as biomass because like natural biomass these More like sewage sludge into biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More through drying and pyrolysisPyrolysis is a thermochemical process that converts waste biomass into bio-char, bio-oil, and pyro-gas. It offers significant advantages in waste valorization, turning low-value materials into economically valuable resources. Its versatility allows for tailored products based on operational conditions, presenting itself as a cost-effective and efficient More. This method not only reduces greenhouse gas emissions but also removes harmful substances such as PFAS, microplastics, and heavy metals.

Traditionally, sewage sludge has been disposed of via composting or landfilling, but these methods are increasingly costly and environmentally problematic. Concerns over health impacts from PFAS and the need to cut greenhouse gas emissions are prompting a reassessment of sludge treatment methods worldwide. Japan, for example, aims to significantly cut emissions from sewage sludge by 2030.

AquaGreen’s innovation stands out because it can dry and pyrolyze sewage sludge using its own caloric content, without needing auxiliary fuel. This approach slashes greenhouse gas emissions by approximately 80% and lowers operational costs compared to traditional methods. AquaGreen’s technology is already in use in Northern Europe, demonstrating its commercial viability and environmental benefits.

Marubeni, with extensive experience in water and wastewater management across the globe, plans to promote AquaGreen’s technologies in Japan, Asia, and Oceania. This collaboration aims to broaden Marubeni’s water service offerings and support environmental sustainability and decarbonization efforts.

Marubeni’s involvement with AquaGreen represents a strategic expansion into the sewage sludge treatment sector, aligning with global efforts to address environmental challenges and improve public health through innovative, sustainable solutions.
