MWC Ash Recycling / AggRite®

Municipal Waste Combustor (MWC) ash is the residue produced when trash is burned to drastically reduce volume (up to 90%) and weight (up to 75%) and/or generate electricity or steam for heating. One of the greatest challenges in effectively managing solid waste is the disposal of MWC ash. Duos addresses this with its patented MWC Ash Recycling Technology.

Housed in a fully-enclosed facility, our technology utilizes state-of-the-art material separation and processing equipment to recovers valuable ferrous and non-ferrous metals and produces AggRite®; a uniform and environmentally safe aggregate. AggRite® possesses the physical and chemical characteristics required for various commercial construction applications, including sub-base material, structural fill, and landfill cover.

Duos MWC Ash Recycling Technology incorporates a Human Machine Interface (HMI) using programmable logic controllers to drive its central motor control system. This fully automated system contributes to safe and efficient control of the ash recycling process.

Some of the benefits of AggRite® recycled material for natural aggregate replacement:

• Zero swell
• Enhanced cold weather handling characteristics
• Requires less dust suppression than natural materials
• Requires less material for some applications
• Consistent manufactured size gradation
• Low permeability
