GPS is a very environmentally friendly company. It recycles 100% of offal to pet food and animal food. Chemical pre-filtration and biological post-filtration ensure 99% purified waste water.
Research by TNO from 1997 (INO-MEP-R 97/089) has shown that GPS is among the most energy-effective companies in the Netherlands and possibly even in Europe (energy costs € 0.008/kg live weight). In 2011 energy costs were € 0.01/kg of live weight. When taking into account the increase in energy prices from 1997 until 2011, this results once again in a savings of 37% of energy costs per kg
We constantly check and measure our energy and water consumption as we want to remain energy effective.
Together with G2 Energy, GPS has realized a solar energy project which consists of 136 thermal solar panels with a total surface of 920 m2. The entire system is installed on the processor’s flat roof.
Each year over 80.000 m3 of gas is saved and 60.000 litres less oil is used compared to before. The CO2 emission has also been reduced by more than 150.000 kg which makes GPS Europe’s most sustainable poultry processor.
The water at GPS is so clean (cleaner than rainwater) that we call it ‘Our spa’.
Years ago, GPS has initiated a pilot project with the government to recycle the water. The water is now for example used to wash the lorries and to clean the floors in the factory.
Processing of feathers
More than half of the feathers are suitable for processing by Ducky Dons. At Ducky Dons they use our feathers to produce 7.000 pillows per day and part is also used to mix in duvets.
The remainder of these by-products goes to Noblesse, where they are converted into flour products and fats for the animal food and pet food industry.
Infiltration project Nunspeet
There are areas on the Veluwe where dehydration of the soil causes problems. In other parts, however, there is a surplus of water. This is also the case in the De Brake district in Nunspeet. During times of relatively heavy rainfall, the groundwater level remains high for a long time, as a result of which water does not drain away from the crawl spaces underneath the houses [Note translator Dutch text: ‘huiden’ should be ‘huizen’]. On the one hand, Water Company Gelderland, in cooperation with the municipality Nunspeet, helps the inhabitants of the De Brake district to combat flooding, while on the other hand they help our poultry processor, which is in need of water.
Water Company Gelderland is working on an infiltration project for the situation in Nunspeet. The surplus of groundwater from the De Brake district is pumped away by means of sump pumps. The water is transported through underground pipes to the nearby woodland. Here, the water will be collected in infiltration ponds where it is infiltrated into the soil. After at least one year (as this is how long it takes before the water reaches a depth of 100 metres) it is then pumped up by GPS where it can be used as first-rate process water.
Drainage of water is provided by three sump pumps with a depth of 40 metres. Drainage is only operational when the groundwater level in the district is high. Since its construction 12 years ago, 25 million cubic metres of water have already been infiltrated. In the same time, 6 million cubic metres of water have been pumped up.
