The inventors have found that containers for disposal of source materials can be constructed or constructed and post-processed to have specifically engineered combustion properties and/or a specifically engineered post-combustion ash compositions, where post-processing relates to augmenting the combustion properties of the containers after they are filled with a source material. The containers may include materials and/or components to alter or engineer specific combustion properties of the containers once filled with a source material or materials. The containers may exclude, eliminate or minimize materials and/or components that render the material unfit as a fuel or form an undesirable ash. The containers may also include materials and/or components that change the composition of the ash formed once the containers are burned. The containers may also be constructed or post-processed with materials, structures, and/or components to alter the combustion properties of the source materials contained therein or to alter the resulting ash composition derived from burning a filled container. The containers may also be processed prior to combustion to change the combustion properties of the container and/or the source materials contained therein and/or to change the resulting ash composition of the container and/or the source material contained therein. Thus, the inventors have found that containers may be constructed and/or post-processed to have a dual use: (1) a receptacle for receiving and transporting source materials, and (2) a fuel component along with the source material contained within the container. As a fuel, the containers and the source materials contained therein may significantly reduce landfill requirements for disposing of the filled containers.

In certain embodiments, the engineered containers are constructed from materials having specific combustion properties and a specific post-combustion ash compositions. In other embodiments, the containers are engineered to be clean burning generating little or no ash. In other embodiments, the containers are engineered to generate an engineered ash composition upon combustion. In all embodiments, the containers, through a judicious selection of materials, may be engineered to have specific combustion properties, such as specific fuel value regardless of a composition of the post-combustion ash and vis-a-versa. Post-processing of the filled containers may result in specific alterations of one or more the combustion properties of the filled containers. The containers may also include coatings, liners, inserts, or other components that change, alter, modify and/or augment the combustion properties or resulting ash compositions of the containers and/or of the source materials within the containers.

The containers of this invention may be constructed of a variety of different materials or mixtures or combinations of different materials to engineer combustion and post-composition ash composition properties. These construction materials have different combustion properties. Thus, by a proper selection of materials and by a proper design of the container, the combustion post-composition ash composition properties of the container as well as the materials contained there in may be adjusted, altered, modified, and/or augmented. Table I includes a list of various construction materials and their combustion properties:
From the data presented above, combustion properties of containers of this invention may be engineered to fuel values between about 6,000 BTU/lb to 20,000 BTU/lb. While the containers may be engineered to have desired fuel values by increasing the amount of high BTU/lb compounds such as polymers, the overall fuel value in BTU/lb of a filled container may be modified by adding into the container high BTU/lb compounds. Thus, the filled containers may have liquid fuels, liquid polymers, powdered polymers, powdered fuels, or mixtures thereof added to the filled containers to increase the fuel value of the filled containers. Additionally, for container designed that have pockets or slots, inserts may be added of high BTU/lb compounds to increase the fuel value of the container. For containers that are coated, the coating may be engineered to improve or retard combustion so that the container starts combusting at an engineered temperatures. The post-combustion ash composition of the container or filled containers may also be altered by added metals or metal oxides to the pockets or slots in the container or added to the interior of the container. By a judicious selection of container construction materials, source material makeup, fill component selection, and container shape and size, the fuel and post-combustion properties of filled and unfilled containers may be altered, modified, and/or augmented. In certain, embodiments, the fuel and post-combustion properties of filled and unfilled containers may be maximized.
All references cited herein are incorporated by reference. Although the invention has been disclosed with reference to its preferred embodiments, from reading this description those of skill in the art may appreciate changes and modification that may be made which do not depart from the scope and spirit of the invention as described above and claimed hereafter.
