  • Publication number: 20240110116
    Abstract: A process of making a fuel product as an additive from a non-auto-combustible high protein organic material for the destruction of polyfluoro compounds in a thermal process system is provided. Thermal reactions within thermal reaction equipment are controlled by controlling the moisture and oxygen in the reaction atmosphere of the equipment and energy inputs at or downstream of a thermal reaction chamber. The concentration of protein thermal decomposition by-products, temperature, and residence time and/or additions of energy within the thermal reaction equipment environment are controlled to destroy hazardous polyfluoro compounds.

  • Patent number: 11913213
    Abstract: Described are embodiments of a modular adjustable linear shower drain system. The drain system is customizable in overall length by cutting portions of the drain system while on-site and prior to assembly. The individual components of the system are made to an oversized, or standard, length and then cut to a desired installation size. Once cut on-site, the components are fit together forming the modular adjustable linear shower drain system. The drain system also includes a height-adjustable shower grill that can be set to match a surrounding tiled area height and angle. The shower grill height is set by adjusting screws disposed in the shower grill and which are in contact with portions of the drain system.
