New energy center at Loacker Recycling GmbH uses biogas and natural gas

The history of Loacker dates back to 1876. At that time, founder Katharina Loacker collected scrap metal in the Rhine Valley in Vorarlberg. The company has continued to grow steadily over the decades. Today, the Loacker Recycling Group has around 45 operating sites and 1,400 employees in eight countries and is one of the leaders in the European waste management industry.

Through its core competence, the recycling of valuable materials, Loacker makes a significant contribution to climate and environmental protection.

This also applies to the new energy center at the Loacker site in Lustenau, Austria. On the one hand, it supplies local heating to Hard, and on the other hand, it generates process heat, e.g., for the biowaste fermentation plant, and heating for the administration. The heat is produced by two Weishaupt monarch® WM-G30 dual-fuel burners with external exhaust gas recirculation, stored in buffer tanks, and released in a controlled manner. The fuel used is biogas produced in-house and natural gas.

A multi-boiler system can be operated more efficiently, especially in the partial load range, if the boiler output can be optimally adjusted to the heat required. Here, Weishaupt offers a sophisticated and practical system with its patented multi-boiler control. Speed-controlled boiler pumps, together with the innovative control concept, provide the solution for the multi-boiler system at the Loacker Recycling energy center.

The volume flow is measured in the consumer network and at each heat generator. Speed-controlled boiler pumps ensure a balanced water flow at each heat generator and correct deviations before they cause temperature disturbances. The next boiler is switched on as late as possible. This mode of operation reduces burner starts to a minimum.
