In December 2019, Primco took over the bio-energy plant in Duiven, Gelderland, in a joint venture with three shareholders. The plant (15 MW) its main objective is the drying of potato and carrot steam peels and other organic waste streams from the food industry. Green electricity is also generated for the public electricity network. Primco owns 75% of the joint venture. The plant will be operational in July 2020.
The drying of potato and carrot steam peels is done with a special drying technique. This technique ensures that a lot of moisture is extracted from the residual flows. In addition, the plant works up woody raw materials work for the chipboard industry and green electricity is supplied to the public electricity network.
High efficiency, almost no particulate emissions
When building the plant, Primco works together with a company that specializes in total solutions for bioenergy systems. Primco also built the heat plant in Lelystad (that has an energy efficiency of at least 95%) with this company. By washing the exhaust gasses, extra efficiency is achieved from the power station, but also almost all fine particles are captured. As a result, the fine dust emissions in Lelystad have such a low value that it remains far below the permitted standard and cannot even be measured.
At Primco Duiven, the same techniques are used and there are opportunities to take advantage of even more available low-value residual heat.
Only local biogenic residual flows
To generate heat and electricity, only local biogenic residual streams from necessary landscape and forest management are used. Rene Buwalda, CEO of Primco, says: “Like in Lelystad we only use local biogenic residual flows, so the CO2 emissions from transport will be kept to a minimum. We want to use all the residual heat, so that as little energy as possible is lost.” In operational and organizational terms, Primco Duiven and Lelystad are going to work very closely together to make further efficiency improvements.
