for cruise ships. The company’s solutions are designed
to reduce pollution, enhance circular resource use,
and support compliance with increasingly stringent
international and national environmental regulations.
Vow’s waste and wastewater treatment systems are
designed and certified in accordance with IMO MARPOL
pollution regulations and the EU Marine Equipment
Directive (MED). The systems are built to meet the most
stringent discharge requirements, including enhanced
nutrient removal in designated Special Areas, and are
aligned with IMO MEPC 269(68) and EU Regulation
1257/2013, which restrict the use of hazardous materials
and promote safe and environmentally sound ship
recycling.
The Advanced Wastewater Purification (AWP) system
treats all wastewater generated onboard passenger
vessels through multi-stage biological treatment and
UV disinfection, significantly reducing the risk of marine
pollution by removing organic matter, nutrients, and
bacteria. As cruise activity expands and environmental
regulations become more stringent, demand for high-
performance wastewater treatment solutions remains
strong.
Traditional onboard waste incineration contribute to
air emissions and permanent loss of natural resources.
Vow’s Electrically Assisted Pyrolysis (EAP) technology
offers an alternative by converting dry waste, food waste,
sewage sludge, and other residual streams into energy
and biochar. The resulting pyrolysis gas can be used for
onboard energy generation, reducing reliance on fossil-
based fuels, while biochar enables material recovery and
supports circular value chains. In this way, the solutions
contribute to reducing air emissions and enabling more
sustainable and circular waste management at sea.

Industrial Solutions
Within Industrial Solutions, encompassing both Circular
Solutions, Heat Treatment Technology and Food Safety,
Vow enables industries to reduce emissions, recover
energy, and improve resource efficiency as part of the
transition to a low-carbon and circular economy.
Pyrolysis is a thermochemical process in which organic
materials are heated in the absence of oxygen. Instead
of being combusted, the material undergoes controlled
thermal decomposition and is converted into three main
outputs: biochar, pyrolysis gas, and pyrolysis oil.
In line with Vow’s strategy of capital discipline and asset-
light growth, Industrial Solutions prioritizes applications
with demonstrated commercial viability. The current
commercial focus is on biomass-to-biocarbon and end-of-
life tires to recover carbon black and tire pyrolysis oil (TPO),
alongside continued growth in heat treatment services.
Through pyrolysis, biomass can be converted into
stable biochar, enabling long-term carbon storage or
substitution of fossil-based carbon such as coal and
coke in energy-intensive industries, including the
metallurgical industry. When applied to end-of-life tires
(ELT), the feedstock is converted into recovered carbon
black, tire pyrolysis oil, and energy-rich gas, enabling
material recovery, reducing landfill dependency, and
supplying lower-carbon inputs to industrial value chains.
Across feedstocks, pyrolysis gas and oil can be reused
for heat, power generation, and industrial applications,
supporting reduced reliance on fossil fuels and improved
energy efficiency and energy security.
Heat treatment processes are energy-intensive and
typically rely on electricity and natural gas for high-
temperature operations. As climate regulations become
more stringent and energy costs and security concerns
increase, demand for energy-efficient furnace systems,
electrification, and retrofit solutions is growing. This creates
opportunities to improve performance, reduce emissions,
and extend the lifetime of existing industrial assets.
Food Safety bases the sterilization of food products
using electrical energy, combined with steam. This
process does not use chemicals to treat food products
and secure a sterilization process that avoids impacting
the food product's texture, taste, and color.
Aftersales
Aftersales is Vow’s segment dedicated to service,
providing lifecycle support primarily for installed
maritime systems. Through the supply of spare parts,
technical services, chemicals, and operational expertise,
Aftersales helps ensure reliable operation, maximum
uptime, and long-term system performance.
Throughout the lifetime of installed systems, Vow
provides tailored service and maintenance to support
efficient operation and regulatory compliance. Spare
parts and chemicals are supplied to both new and
existing installations, helping to maintain stable process
performance while optimizing resource use. Preventive
maintenance programs and global technical service
activities, including inspections, onboard service
visits, troubleshooting, and system tuning, help reduce
downtime and maintain efficient system operation.
Mid-life upgrades and refurbishment of components
such as automation systems, pumps, and dosing
equipment enable customers to modernize existing
installations rather than replace them. By extending
system lifetime and maintaining efficient operation,
Aftersales supports circular economy principles
through lifecycle-based services and long-term system
performance.
