INSTALLATION AND METHOD FOR DESTROYING PYROTECHNIC WASTE
An installation for destroying waste includes at least traces of energetic materials, comprising: an enclosure delimited by lateral walls, the enclosure being filled with a liquid medium up to a first level; a chamber comprising: an inlet intended to supply the chamber with waste to be destroyed by combustion in the chamber; an outlet; a discharge line extending between a first end and a second end, the first end being connected to the outlet of the chamber, the second end being situated in the liquid medium, the discharge line rising, between its first end and its second end, to a second level which is higher than the first level, the discharge line being configured to discharge, at the second end, gases and volatile solid residues which are produced in the chamber during combustion.
Method and compositions for rendering opioids safe
Exemplary compositions, methods, systems, and kits are disclosed that render excess pharmaceuticals safe by chemically transforming the active pharmaceutical ingredient into an environmentally benign and biologically inert form. The methods and kits have additional advantages of convenience, low cost, long shelf life, and ease of handling.
Methods for cannabis waste disposal
Systems and methods for rendering cannabis-related waste materials are provided. The method may include inserting a plurality of cannabis-related waste materials into, for example, a mobile rendering vehicle. The method may further include physically altering the cannabis-related waste materials such that the cannabis-related waste materials are unrecognizable and unusable. The insertion of the cannabis-related waste materials into the mobile rendering vehicle may be recorded and/or the physical alteration (e.g., pulverization) of the cannabis-related waste materials may be recorded via one or more cameras disposed on the mobile rendering vehicle to verify proper insertion and/or alteration of the cannabis-related waste materials.

Method for mitigating acid rock drainage potential through the smoldering combustion of organic materials
Methods are provided for the removal of sulfur and other ARD/AMD-generating materials through the smoldering combustion of an organic material. The methods comprise admixing an ARD/AMD-generating porous matrix material with an organic material to produce a mixture, exposing the mixture to an oxidant, and initiating a self-sustaining smoldering combustion of the mixture. Additional embodiments aggregate the organic material or ARD/AMD-generating porous matrix material or mixture thereof in an impoundment such as a reaction vessel, depression or matrix pile. Further embodiments utilize at least one heater to initiate combustion and at least one air supply port to supply oxidant to initiate and maintain combustion.

HYDROGEL-ENZYME SYSTEMS AND METHODS
In one embodiment, a hydrogel-enzyme construct for performing high temperature enzymatic reaction on paraoxon, and/or for performing enzymatic reaction on paraoxon following exposure to high temperature, includes a hydrogel having multiple layers of poly(methacrylic acid) (PMAA) and a plurality of dPTE2 enzyme molecules. Individual dPTE2 enzyme molecules are embedded between adjacent PMAA layers and are covalently bonded with respective individual PMAA layers. The hydrogel-enzyme construct is capable of performing enzymatic reaction on the paraoxon when the paraoxon is exposed to the hydrogel-enzyme construct under a temperature condition of up to above 99° C. and below 100° C. or when the paraoxon is exposed to the hydrogel-enzyme construct after the hydrogel-enzyme construct has been heated to a temperature condition of up to 550° C., where the enzymatic reaction on the paraoxon by individual dPTE2 molecules embedded within the hydrogel occurs at a residual activity of between 20% and 100%.
