Title: Innovations by Francis I Daniels
Introduction
Francis I Daniels is an accomplished inventor based in Clearwater, FL (US). He has made significant contributions to the field of environmental engineering, particularly in the area of waste management and construction materials. With a total of 2 patents, his work focuses on the immobilization of toxic elements found in incinerator ash.
Latest Patents
One of his latest patents involves a composition suitable for use as a base in the construction of roads, parking lots, and other areas. This innovative formulation is created from an ash aggregate comprising municipal solid waste incinerator ash (MSWIA) mixed with an aggregate material. Upon the addition of cement, compaction, and curing, a volumetrically stable solid is formed. The process includes combining the incinerator ash with an aggregate material, which is then crushed and sifted to remove larger particles. The moisture content of the mixtures is carefully adjusted to achieve maximum compressive strength. When ash aggregates containing less than 50 percent MSWIA are combined with at least 5 percent cement by dry weight, stable solids are formed within seven days, exhibiting compressive strengths exceeding 300 psi. These stable solids effectively immobilize heavy metals in the MSWIA, ensuring that leachates from EPA toxicity tests meet the maximum allowable concentrations for non-hazardous materials.
