Heat from pig manure

Using air scrubbers to not only filter odours and ammonia from pigsties but also extract heat from the air. Pigs2Heat, developed by Loohuis Agro Neutraal from Ondernemend Vroomshoop in Twente delivers energy savings and concrete sustainability solutions for the livestock farming industry. The heating unit upgrades lukewarm water that is extracted by the air scrubber to a usable temperature of 35 to 65 degrees Celsius. This water can be used to run floor heating in pigsties sustainably.

In short

  • Pigs2Heat delivers energy savings and concrete sustainability solutions for the livestock farming industry

Pigs produce ammonia, among other things. An air scrubber can be installed to filter the outgoing ventilation air from odours and ammonia. This installation prevents the emission of environmentally unfriendly gases.

Air heating

Advanced air scrubbers can not only filter the air but also extract heat from the air into water. This air heat can be used purposefully. Depending on how the pigsty is heated, extracted air is between has a temperature of 25 to 30 degrees Celsius.

Upgraded temperature

Water in the air scrubber is not pure, as all sorts of additions are present. That’s why a plate heat exchanger is needed to transfer the heat stored in the water to the Pigs2Heat unit. In this unit the water temperature is upgraded to 65 degrees Celsius, to be used to heat the pigsty. For example, the heat can be used in the floor heating installation. The Pigs2Heat unit needs to be adjusted to the available ventilation air and required heating capacity.
