Project Innovation + Advantages:

Designs by Natural Processes, Inc., aims to make novel cement at ambient temperature using 55% municipal solid waste (MSW) incinerator ash. The team will add low-cost chemicals to better sequester environmentally problematic combustion gases, chemicals, and heavy metals during incineration, eliminating undesired chemicals in the ash-rich cement leachate. The team's objective is to develop an alternative to traditional ordinary Portland cement (OPC), which cannot sequester nearly as much ash (16%). OPC requires a temperature of 1300°C for its manufacture, and sets up in about a month for a compressive strength of approximately 3000 psi. In contrast, the novel cement uses more ash, is chemically based, uses no heat, gives off no CO2, hardens quickly, and averages high strength.
