The next generation of maritime dehydration technology
Handles 50 – 1,000 kg of wet waste daily
Stays ahead of evolving regulations
Reduces wet waste volume by 80%
Decreases emissions by 85% vs landfilling
Maritime regulations are rapidly evolving
The maritime industry is riding a wave of stricter regulations, fundamentally reshaping how we protect our ecosystems. Clearly, a zero-discharge future isn’t on the horizon – it’s here. Yet, for vessels with fewer people on board, traditional waste management solutions often miss the mark.
MARPOL IV
Vessels must install approved STPs and/or maintain sewage tanks. Otherwise, untreated sludge must be offloaded at port.
MARPOL V
Garbage discharge, including food waste, is restricted beyond 12 NM. In Special Areas, all waste must be offloaded at port.
IMO
The IMO has adopted a comprehensive strategy. Specifically, it aims for zero plastic waste discharges from ships by 2025.
EU
Vessels calling at EU ports must deliver all waste to port or store it, effectively prohibiting waste discharge, even beyond 12 NM.

Empowering onboard waste treatment in smaller vessels
Existing onboard waste systems require high volumes to be cost-effective. As a result, smaller vessels are left reliant on land-based offloading or direct discharge. However, Evac Dehydro changes that. Now, vessels generating 50–1,000 kg of wet waste daily – including yachts, river cruisers, RoPax, merchant, and offshore vessels – can adopt circular onboard waste management. Consequently, it empowers vessel owners of all sizes to adapt as the maritime industry moves toward a zero-discharge future.

Evac Dehydro FAQ
What makes Evac Dehydro different from traditional onboard waste treatment systems?
Evac Dehydro introduces an entirely new approach to onboard waste management by using advanced dehydration technology to remove moisture from organic waste, reducing its volume by up to 80%.
Unlike traditional waste storage methods or biodigesters, Dehydro transforms waste into a sterile, dry powder that is easy to handle and store. Consequently, it eliminates the need for further treatment and significantly simplifies offloading.
In addition, it minimizes storage requirements, reduces odors, and lowers operational costs—ultimately making it a smarter and more sustainable alternative for smaller vessels.
How does Evac Dehydro help vessels reduce waste volume and offloading costs?
By dehydrating wet waste and converting it into a dry, lightweight material, Evac Dehydro significantly reduces the amount of waste that must be stored and offloaded.
Consequently, vessels face fewer onboard storage demands, which in turn frees up valuable space for other operational needs. Moreover, offloading becomes less frequent, resulting in notable savings on port service fees.
Additionally, lighter and drier waste simplifies handling and reduces transportation-related expenses. Ultimately, fewer waste-related emissions from offloading and transport contribute to a lower overall carbon footprint.
What types of vessels benefit most from Evac Dehydro’s technology?
Evac Dehydro is optimized for vessels that generate 50–1,000 kg of wet waste per day, making it an ideal solution for:
• Ideal for superyachts & megayachts – space-efficient waste management for luxury vessels.
• A smart fit for river cruises & RoPax ferries – reducing waste handling for high-passenger traffic vessels.
• Designed to serve naval ships & offshore support vessels – improving waste efficiency in restricted spaces.
• Suitable for small merchant vessels & cargo ships – a practical, low-maintenance solution for long voyages.
How does Evac Dehydro support compliance with MARPOL and IMO waste regulations?
Evac Dehydro is designed to help vessels meet MARPOL Annex V and IMO environmental standards through a number of key features.
First, it eliminates the need for untreated waste discharge, enabling vessels to comply with global no-discharge regulations. Additionally, it produces a sterilized, dry byproduct that makes onboard waste handling and disposal more efficient. By reducing the overall volume of stored waste, Evac Dehydro also helps vessels meet port reception facility requirements with greater ease.
Finally, it plays an active role in minimizing carbon emissions, directly contributing to the IMO’s decarbonization goals for the maritime sector.
What are the key differences between Evac Dehydro and HydroTreat, and how do they complement each other?
While both Evac Dehydro and HydroTreat provide sustainable onboard waste management, they are designed for different vessel needs:
Firstly, Evac Dehydro is tailored for smaller vessels producing moderate waste volumes. Consequently, organic waste is dehydrated into a sterile, dry powder, significantly reducing storage needs and offloading frequency.
Meanwhile, Evac HydroTreat is ideal for larger vessels with higher waste loads. As a result, it offers a complete organic waste treatment process without harmful emissions.
Together, Dehydro and HydroTreat create a comprehensive waste management solution that covers a wide range of vessel sizes and waste-processing requirements. This ensures vessels remain operationally efficient and fully compliant with environmental regulations.
