SPIE Netherlands, in partnership with C-Green, has embarked on an extraordinary endeavor to develop the first modular plant in the Netherlands dedicated to converting sewage sludge into biofuel. This groundbreaking system, masterfully crafted by C-Green, employs an energy-efficient process to transform wet biomass, specifically sludge, into a dry substance known as hydrochar.
Throughout the production process, each five kilograms of sludge undergoes a remarkable metamorphosis, culminating in the creation of one kilogram of hydrochar. This organic and ecologically sound end product serves as an exceptional biofuel and soil conditioner, offering a sustainable solution to environmental challenges.
During the Maintenance NEXT event, SPIE and C-Green forged a collaborative agreement to construct this innovative plant. Leveraging SPIE's engineering expertise, the system is being meticulously erected in the Netherlands under the guidance of C-Green.
Ordinarily, the decomposition process of sludge by-products generates methane gas, a greenhouse gas that possesses a staggering climate impact up to 40 times greater than carbon dioxide. Furthermore, the collection and transportation of wet sludge incur significant costs. The modular plant represents a promising resolution to these pressing concerns. By converting sludge into a dry substance, methane gas emissions are entirely mitigated, while simultaneously reducing volume, optimizing transport efficiency, and yielding cost savings.
This compact and adaptable plant, comprised of readily deployable modules, can be conveniently situated at wastewater treatment plants or pulp mills, affording the capability to process an impressive 25,000 tonnes of sludge annually. The final product can be stored on-site, enabling seamless integration within existing infrastructures while streamlining waste management operations.
In the forthcoming months, REYM Rotterdam, a prominent waste management company in the Netherlands, will initiate pilot testing of the installation. The collaboration between REYM, C-Green, SPIE, and InnoEnergy (an esteemed investor and shareholder of C-Green) was facilitated by iTanks, a renowned knowledge and innovation platform in the port-related industry.
