The present disclosure describes a unique, two-part, water-soluble polymer matrix material and a method of application that immobilizes a wide variety of loose powder or crystalline hazardous materials and renders them safe or at least safer for handling and transport. The polymer matrix material is a two-part polymer material comprising a liquid cross-linking polymer and a cross-linking agent, initiator, or biocide contained in a solution. The cross-linking agent functions to cross-link the polymer and cause it to harden in place.

A composition for removing spillage on asphalt paving of hydrocarbon substances which includes modifiers, chemical oxidizers and bacteria which metabolizes both the spillage and a softened top layer of asphalt paving to aid in rehardening the surface of the mat while not metabolizing the underlying asphalt paving unaffected by the spillage.

Disclosed herein are aggregators that can be cellulosic particles having high oil sorption capacity, high hydrophobicity, high buoyancy in water, and an aggregation quality that can support environmental remediation of hydrocarbon spills (e.g., crude oil spills) by various cleanup strategies including burning, skimming, or bioremediation. Also disclosed are methods of making the materials and methods of using the materials for environmental remediation.

A method for preparing a biological composition for degrading plant pesticide residues includes: (1) preparing a mixture of a dried coconut shell powder having a water content of less than 3 wt % and a particle diameter of not more than 2 mm and a dried licorice powder having a water content of less than 1 wt % and a particle diameter of not more than 2 mm; (2) hydrolyzing the mixture in a cellulase buffer at pH 4.5 to 5.5 for at least 36 hours, and filtering the mixture to obtain an enzymatic hydrolysate; and (3) adding the enzymatic hydrolysate to a bacteria mixture of yeast and lactic acid bacteria and fermenting at 30 C. to 35 C. for 7-10 days, and centrifuging and lyophilizing to obtain the biological composition.

A local neutralizing device for strong acid or strong base accidental environmental contamination is provided in the form of a compressed canister with a content distribution means which is portable and target control specific by a user to dispense a weak base to a strong acid accident location to neutralize the strong acid, or alternatively to dispense a weak acid to a strong base accident location to neutralize the strong base, either alternative intended to reduce, contain, neutralize and assist in the remediation of the accidental spill.

Microbiological cleaning formulations may include an aqueous solution of a microbial component comprising at least one sporogenous microbial species. The microbiological cleaning formulation may also include a nonionic surfactant. The microbiological cleaning formulations may further include additives, solvents, preservatives, stabilizers, and fragrance agents. The microbiological formulations are such that they may removes organic carcinogens from a surface of a material contaminated during firefighting-related activities or from exposure to organic carcinogens. Corresponding methods for removing organic carcinogens from a surface of a firefighting material may include applying the microbiological cleaning formulation on the surface of the firefighting material. Corresponding cleaning kits may include the microbiological cleaning formulation and an optional scrubbing element.

A method and composition for biodegrading or bioremediating a pyrene or other polycyclic aromatic hydrocarbon (PAH) with one or more bacteria of the genus Halomonas or Idiomarina. Bacterial strains useful for degrading or remediating pyrenes and other polycyclic aromatic hydrocarbons.
