In order to comply with new Massachusetts regulations preventing the disposal of food waste in landfills, Ahold sought a way to beneficially reuse unsalable organic material from their grocery stores throughout the New England region, resulting in the development of an anaerobic digester.
Project Highlights
Dennis Group designed and built a Product Recovery Operation (PRO) at Ahold’s distribution center. The PRO facility consists of equipment capable of processing 130 tons of food waste daily, converting the waste into feedstock for a 1.3 MM gallon anaerobic digester.
Biogas produced for the anaerobic digestion process powers a 1.1 MW generator, providing renewable energy to power the distribution center.
The facility reduces Ahold’s food waste to landfill by 25,000 tons annually.
The PRO plan produces 30% of the distribution center’s electricity.
Dennis Group was able to secure $1.3 MM in energy efficiency rebates and grants for the project.
Dennis Group completed a master planning study for the layout of a grass roots facility to be built in Las Vegas. The scope of the project included:
Developing a design basis for the new facility in terms of production and process system capacities
Determination of building size to meet current and future needs
Layout of the employee, process and utility areas of the facility including bulk liquid receiving by rail/truck
Layout of rocess areas for batch and continuous emulsion systems, starch preparation, cooking operations for sauces, dry ingredient blending and line layouts for high speed retail glass, food service, bulk tub and portion control lines
During the implementation phase of the project, Dennis Group provided complete building mechanical and electrical design, environmental design and permitting and coordination of architect, structural engineer, civil engineer activities for a 140,000 SF salad dressing plant.
Segregated waste systems and stringent sanitary design requirements were key features of this project.
