Decarbonization with Evac’s Total Concept & HydroTreat: Zero direct emissions

Accelerating decarbonization

Decarbonization is not just a compliance requirement; it is an opportunity for the maritime industry to lead in global sustainability efforts. With increasing pressure to reduce GHG emissions, decision-makers within the maritime industry are looking into technologies that not only meet but exceed regulatory standards to future-proof their investments. HydroTreat, with its circular onboard waste treatment technology, provides a pathway to achieve these ambitious goals.

Zero direct emissions and low indirect emissions with HydroTreat

HydroTreat is designed to tackle the pressing issue of emissions head-on. By utilizing the HTC process, HydroTreat ensures that waste is processed in a non-incineration manner, producing no exhaust gas and thus eliminating direct emissions to both the sea and atmosphere. This makes HydroTreat a critical asset for vessels aiming to minimize their environmental footprint. The only byproduct of the system is HTC-biochar, a valuable resource that can be used to improve soil productivity, promoting a circular economy.

Indirect emissions, often stemming from energy consumption, are also addressed by HydroTreat’s energy-efficient design. The system significantly reduces fuel consumption by utilizing advanced heat exchangers to retain heat and lower energy usage compared to alternative methods like thermal dryers and incineration.

HydroTreat’s revolutionary approach to onboard waste treatment and extreme energy efficiency leads to a total reduction of 80% in CO2 emissions, and 60% in fuel consumption compared to alternative systems using thermal dryers and incineration. This not only supports decarbonization efforts but also offers substantial cost savings in fuel expenditures. For a 5,000-person cruise vessel, this translates to a potential annual fuel saving of 250 tons of diesel.

Extending the lifespan of your investments

By substantially lowering the vessel’s environmental footprint, HydroTreat helps vessels comply with the current MARPOL Annex IV and V regulations.

Furthermore, the IMO’s revised GHG reduction strategy, adopted in July 2023, sets ambitious targets to achieve net-zero greenhouse gas (GHG) emissions from international shipping by or around 2050. This strategy includes a commitment to ensuring the uptake of alternative zero and near-zero GHG fuels by 2030 and establishes indicative checkpoints for 2030 and 2040 to achieve significant reductions in emissions. HydroTreat aligns perfectly with these ambitious goals.

By adopting HydroTreat, ship owners can ensure compliance with these rigorous international standards, thereby mitigating risks associated with non-compliance, such as hefty fines and operational delays, and extending the lifespan of their investments.

Saving cost by saving space

HydroTreat’s benefits extend beyond its sustainable characteristics and compliance. By effectively eliminating the need to store contaminated waste onboard the vessel, HydroTreat reduces the volume of wet organic waste by 90%. This also means saving on the costly offloading fees of contaminated waste.

HydroTreat’s waste management efficiency translates to lower lifecycle costs and added spatial advantage, allowing you to focus on and increase your core business activities. This makes HydroTreat not just a sustainable option but also a financially viable one for ship owners and operators.

Upgrade to a circular future with HydroTreat

In the face of stringent regulations and the global push for decarbonization, HydroTreat emerges as a leading solution for the maritime industry. By ensuring zero direct emissions, significantly lowering indirect emissions, eliminating the need to store and offload contaminated waste, and reducing vessel lifecycle costs, it helps ships navigate towards a more sustainable and economically sound future. Furthermore, HydroTreat contributes to the circular economy by transforming waste into HTC-biochar, which can be returned to the soil, improving soil productivity and closing the circularity loop in sustainable waste management.

Partner with Evac HydroTreat to equip your vessels with a circular onboard waste management system and lead the charge in maritime decarbonization.
