The aim is to utilize the nutrients of the sludge by making cheap and safe recycled fertilizers and producing district heat as a by-product. The benefits of the process are that microplastic or other harmful substances do not pass to the crop with the fertilizers.
Laitex was responsible for the mechanical conveying system between Endev’s dryer and reactor. Drying of the sludge is done with hot sand which is recycled in the system.
The conveying system Laitex delivered can be presented in three phases: Sand feeding to the reactor, Hot sand feeding to dryer and recycling and Sludge-sand mixture feeding to the reactor. The scope also included installation.
Laitex and Endev have a great opportunity to face the challenge together as this first commercial delivery test plant is an example of a circular economy.
