The GreenWhey Energy project is a greenfield development that recycles food waste from the dairy industry and generates electricity. Miron has been integrally involved in the development of this project from active participation in the conceptual design, initial estimating, permitting, and assembly to the leading of the detailed design, value engineering, and constructability reviews. Miron also provided rigorous involvement and support of project financing, balance of plant equipment procurement, construction, and start-up/commissioning.
Miron’s scope of work included the following:
High strength wastewater from area dairies is piped and trucked to the site and unloaded into one of several lined reinforced concrete equalization tanks. The contents of these tanks is pumped to a lined reinforced concrete preconditioning tank where the feedstock is blended and fed into two 2 MG reinforced concrete anaerobic digesters that consume and break down the organic material and produce methane. The methane is then supplied to two CAT 3520 biogas engine generators that generate 3.2 MW of electricity that is sold to Xcel Energy for distribution on their grid. Hot water from the biogas engine generator heat recovery systems is captured and utilized for building heat, preheating of the feedstock in the preconditioning tank, and maintenance of the temperature of the anaerobic digesters.
