Sustainability

Our solutions support customers to develop their business in a sustainable way, as all our products and processes are designed to contribute to a better environment and cleaner seas.

At Evac, sustainability is the cornerstone of our operations. We develop technologies that address the increasing need for innovative cleantech solutions, driven by the megatrends of climate change, the need for energy efficiency, and increasingly scarce fresh water resources.

As a preferred partner our vision is to build a cleaner world for everyone by helping our customers meet their waste and water management related environmental performance targets wherever they operate.

We contribute to a better environment and cleaner seas by helping our customers:

  • Reduce water consumption
  • Treat and recycle waste
  • Manage food waste responsibly
  • Purify wastewater
  • Generate fresh water from sea water.

Reducing water consumption with vacuum collection systems

Our energy-efficient vacuum collection systems play an important role in conserving the world’s scarce water resources. They ensure that our customers can treat wastewater responsibly to the highest quality and according to all relevant regulations.

Evac vacuum toilets significantly reduce water consumption. Compared to traditional gravity toilets, which consume between four and nine liters (1 – 2.4 gallons) of water per flush, our vacuum toilets consume just 1.2 liters (0.4 gallons) per flush. On a cruise vessel with 3,300 passengers each flushing a toilet 10 times a day, this adds up to a minimum daily saving of 92,400 liters (24,410 gallons) of water.

Purifying wastewater with wastewater treatment systems

Evac wastewater treatment systems allow our customers to collect and treat wastewater, as well as generate fresh water, with a remarkably low impact on the environment. Our systems can purify wastewater to 99% clean effluent, which can be safely discharged or reused, and 1% sludge, which can be safely burned in our incinerators.

In 2017, Evac membrane bioreactors (sold since 2010 alone) have purified 11,757 m3 of water per day. On average, a person generates 150 liters of wastewater per day on a land side. Based on this, in a year our systems purify a volume of wastewater equivalent to that generated by a town with 80,000 inhabitants.

Daily waste amount

The volume of treated and non-treated recyclable and non-recyclable waste created per day on board a cruise vessel with 3,300 passengers. On average, waste compaction using Evac systems reduces the volume of waste that needs to be taken ashore for treatment in ratio 1:10.

Treating and recycling waste with dry and wet waste treatment systems

Our systems support customers in achieving their environmental goals by ensuring that they can treat mixed or recyclable waste in a safe, environmentally friendly, and energy efficient way. They also reduce waste volumes by sorting, compaction, shredding, and burning.

The illustration on the right shows the volume of recyclable and non-recyclable waste created per day on board a cruise vessel with 3,300 passengers and the volume of waste remaining after burning or compacting using our systems. On average, waste compaction using Evac systems reduces the volume of waste that needs to be taken ashore for treatment in ratio 1:10.

Responsible management of food waste

Proper treatment and recycling of food waste is essential in order to comply with environmental regulations, particularly in the marine sector. In order to protect the marine environment, vessels and offshore installations must be able to responsibly manage the food-based waste generated on board. Evac macerating units and vacuum collection units can be used to reduce food waste volumes and store waste onboard ready for proper recycling or disposal on shore.

Conserving scarce water resources with freshwater generation systems

In the marine sector, our customers can generate fresh water from seawater with our desalination units using reverse osmosis (RO) technology. This contributes to a significant reduction in fresh water consumption by vessels and offshore installations. By enabling seawater to be turned into process, service, and drinking water, reverse osmosis technology plays an important role in conserving the world’s scarce water resources. It is also more economical and energy efficient than distillation-based systems.

Since 2000, our reverse osmosis desalination plants have generated 8,000,000 m3 of fresh water from seawater*. This amount of water would fill 229,000 standard tanker trucks.

Our systems supporting sustainability aboard Tallink’s Megastar ferry

Evac Complete Cleantech Solution including vacuum collection, waste water treatment, dry and wet waste treatment, fresh water generation and automation systems can be found aboard Megastar, the new generation LNG shuttle ferry of AS Tallink Grupp.

Green values have been very carefully taken into account in the design of the ferry. The ship complies with the new and stricter emission regulations for the ECA areas including the Baltic Sea.
