Environmental award for wastewater project

DONG Energy's gas treatment plant in Nybro has received the Danish voluntary-based environmental network GREENET's environmental award 2013 in recognition of their work on reducing wastewater discharge.

Facts

The wastewater project at Nybro gas treatment plant has resulted in large energy savings for the Nybro and Varde purification plants.

Nybro pump concumption: 3000KWh

Varde purification plant: 9600KWh*
*(2010 figures, on average 1,28KWh/processed m3)

GREENET is a Danish voluntary-based environmental network for business, authorities and the municipalities of Billund, Esbjerg, Fanø, Varde and Vejen as well as other potential shareholders. DONG Energy has been a member since 2005.

Each autumn, GREENET elects a winner of the environmental award among the companies of the network which has distinguished itself in the environmental field.

80% of the 'wastewater' (surface water) lead from Nybro to Varde's purification plant was clean water. Therefore, until now the purification plant has been unnecessarily strained and too much energy has been used on 'cleaning clean water'. In future, this will change thanks to new thinking and an innovative cost savings project.
 
Today, the wastewater discharge to the purification plant has been reduced by 89%. This reduction results in major financial operational advantages and significant energy savings for the purification plant. The positive results have been achieved in connection with a wastewater project which was initiated by the employees at the Nybro gas treatment plant in 2011. The annual energy savings correspond to an emission of seven tonnes CO2 or the annual electricity consumption of 2.5 households (4 persons).
 
"The project has more than fulfilled our expectations, and we hope that this model will be used by other companies to help avoid unnecessary adverse impact on the environment," said Henrik Bay, Manager at Nybro gas treatment plant. 
 
The surface water was previously defined as 'wastewater', but through dialogue with the authorities and the introduction of new procedures for water management, it is now possible to lead the water directly to the recipient* instead of to the purification plant.
 
In connection with the presentation of the environmental award, GREENET emphasised that Nybro gas treatment plant is:
  • at the forefront of the development in the environmental field
  • an active player and committed to the environmental work in the region
  • continuously working on preventing pollution and reducing resource consumption. 
*in wastewater terminology, recipient means sea, streams, percolation, etc.
