Technology for in situ remediation of undetonated explosive material. An explosive apparatus contains an explosive material in close proximity with a carrier containing microorganisms and with nutrient for the microorganisms. An explosive mixture capable of self remediation includes an explosive material that is intermixed with or lies proximate to the carrier. The microorganisms are either mobile or temporarily deactivated by freeze drying until rehydrated and remobilized. The microorganisms are capable of metabolizing the explosive material. Examples of such microorganisms includespp.,spp.,spp.,spp.,spp., and denitrifying microorganisms. If the explosive material fails to detonate, the explosive is remediated by the action of the microorganisms. Remediation includes both disabling of the explosive material and detoxification of the resulting chemical compositions.

Explosive device with accelerated bioremediation capacity

Technology for in situ remediation of undetonated explosive device. An explosive device contains an explosive material in close proximity with microorganisms capable of metabolizing the explosive material that are either mobile or temporarily deactivated by freeze drying. Examples includespp.,spp.,spp.,spp.,spp., and denitrifying microorganisms. A self-remediating explosive mixture includes an explosive material intermixed with microorganisms. Joined with an explosive device is a bioremediation apparatus that contains microorganisms and prevents contact between microorganisms and explosive material in the explosive device using a barrier that is actuated to release the microorganisms by mechanical, electrical, or chemical mechanisms. If the explosive device fails to detonate, remediation by microorganisms includes both disabling of the explosive material and detoxification of resulting chemical compositions.

An explosive mixture capable of self remediation includes an explosive material that is intermixed with or lies proximate to the carrier. The microorganisms are either mobile or temporarily deactivated by freeze drying until rehydrated and remobilized. The microorganisms are capable of metabolizing the explosive material. Examples of such microorganisms include Pseudomonas spp., Escherichia spp., Morganella spp., Rhodococcus spp., Comamonas spp., and denitrifying microorganisms. If the explosive material fails to detonate, the explosive is remediated by the action of the microorganisms.

Methods, apparatus, and systems for accelerated bioremediation of explosives

Technology for in situ remediation of undetonated explosive material. An explosive apparatus contains an explosive material in close proximity with microorganisms. An explosive mixture capable of self remediation in the form of an explosive material is intermixed with microorganisms. The microorganisms are either mobile or temporarily deactivated by freeze drying until rehydrated and remobilized. The microorganisms are capable of metabolizing the explosive material. Examples of such microorganisms include Pseudomonas spp., Escherichia spp., Morganella spp., Rhodococcus spp., Comamonas spp., and denitrifying microorganisms. A bioremediation apparatus that contains microorganisms and prevents contact between the microorganisms and explosive material is joined with an explosive apparatus that houses a charge of explosive material. A barrier is actuated by mechanical, electrical or chemical mechanisms to release the microorganisms into the explosive assembly to enable the microorganisms to begin metabolizing the explosive material, when the explosive apparatus is joined with the bioremediating apparatus. If the explosive material fails to detonate, the explosive is remediated by the action of the microorganisms. Remediation includes both disabling of the explosive material and detoxification of the resulting chemical compositions.

Method for manufacturing explosive device having self-remediating capacity

Explosive with bioremediating capacity

Technology for in situ remediation of undetonated explosive material. A bioremediating apparatus in the form of a storage chamber houses in moist condition type of microorganisms capable of metabolizing the explosive material. Examples of such microorganisms include Pseudomonas spp., Escherichia coli, Morganella morganii, Rhodococcus spp., Comamonas spp., and denitrifying bacteria. The bioremediating apparatus is joined with an explosive apparatus that houses a charge of explosive material. A solution released into the storage chamber by opening a first valve hydrates the microorganisms. The explosive assembly has an actuation means for opening the first valve and a second valve that releases the microorganisms from the storage chamber to begin metabolizing the explosive material, when the explosive apparatus is joined with the bioremediating apparatus. If the explosive material fails to detonate, the explosive is remediated by the action of the microorganisms. Remediation includes both disabling of the explosive material and detoxification of the resulting chemical compositions. The valves utilized are either mechanical, and thus opened by the coupling of the bioremediating apparatus to the explosive apparatus, or comprised of a slowly effacing material, such as gelatin. A micro-scale form of a bioremediating apparatus includes microorganisms encapsulated in gelatin for disposition mixed in or contacting the explosive material.
